A hastily adopted compromise decision that was taken without any impact assessment, despite the risk that it will negatively affect the environment and the health of Europeans.

In early April the International Maritime Organization (IMO) decided to abandon the fixed start date for the stricter Tier III emission standards that will apply to new ships when plying in NOx Emission Control Areas (NECAs). Instead, the IMO will replace the 2016 application date with flexible provisions for any NECAs established after that date.

The law on NECAs, including the 2016 application date, was adopted unanimously by the IMO in 2008 as part of the revision of MARPOL Annex VI, the global instrument that regulates air pollutant emissions from international shipping.

Under the original 2008 rules, all ships built after 1 January 2016 sailing in designated NECA waters would have to comply with stricter NOx standards. As a result of the change adopted on 4 April, only ships built after the adoption of a NECA would have to comply, which means that if a new NECA enters into force in 2020 for example, the Tier III standards would not apply to ships built in the four years 2016–2019.

The North American NECA, which has already been approved and adopted, will not be affected and here the Tier III standards will apply as from 2016.

However, over the last few years, the countries surrounding the Baltic Sea and the North Sea have been preparing submissions to the IMO in a move to get these two sea areas – which are both already designated as Sulphur Emission Control Areas (SECAs) – also designated as NECAs. The new amendment means that delays in the adoption of these, or any other, sea areas as new NECAs will result in even higher NOx emissions.

“The IMO’s decision to delay NOx regulations is a serious setback for efforts to tackle the biggest source of nitrogen oxides in Europe, which is an invisible killer causing cancer and lung disease,” said Bill Hemmings, programme manager for shipping at the green group Transport and Environment (T&E).

The outcome was, however, welcomed by Russia, which last year proposed a five-year delay for the entry into force of the Tier III NECA standards. Russia has for some time now also been blocking a decision by the Baltic Sea countries to submit the Baltic Sea NECA proposal to the IMO.

Some countries argued that without a delay for the Tier III standards for new NECAs, the prospect of having a NECA approved in the near future for the Baltic Sea would be slim, and that the same might apply to other prospective NECAs as well.

“It remains to be seen whether this decision will enhance the prospects for the establishment of NECAs in the Baltic and North seas. If such applications are not soon forthcoming, it may have the reverse effect of hastening the need for retrofitting of ships serving ports in Europe in order to curb growing emissions. We urge the Baltic and North Sea countries to submit their applications for new NOx emissions control areas as soon as possible,” Hemmings concluded.

The Clean Shipping Coalition pointed out that the decision risks bringing the IMO’s credibility as a regulatory body into question, making future negotiations at IMO more difficult and protracted, as negotiators will have no assurance that agreements made today will be respected tomorrow. Moreover, it may signal to shipowners and manufacturers of engines and after-treatment technologies that the IMO rulemaking process is arbitrary and that adopted IMO regulations cannot be relied on but should be treated as provisional only.

What is IMO 2020?

The International Maritime Organisation (IMO) has ruled that from 1 January 2020, marine sector emissions in international waters be slashed. The marine sector will have to reduce sulphur emissions by over 80% by switching to lower sulphur fuels. The current maximum fuel oil sulphur limit of 3.5 weight percent (wt%) will fall to 0.5 wt%. IMO 2020 regulations will see the largest reduction in the sulphur content of a transportation fuel undertaken at one time.

Why is everyone talking about a fuel specification?

The marine sector, which consumed 3.8 million barrels per day of fuel oil in 2017, is responsible for half of global fuel oil demand. IMO sulphur regulations therefore have the potential to be highly disruptive to the pricing and availability of compliant fuels.

Who will be affected by IMO 2020?

The costs of ocean going freight will increase as the marine sector uses more costly fuels, which has wide reaching consequences across the global economy. The impact could be felt from mid-2019 onwards and last for a few years, as the refining and shipping sectors adapt.

What does IMO 2020 mean for my business?

Growing demand for middle distillates could result in upward price pressure on fuels such as diesel and jet fuel. Knock-on effects from the upcoming cap on sulphur emissions in marine bunker fuel could even wind up giving you a more expensive plane ticket in 2020. Get detailed analysis for your industry and sector below.

Merchant shipping is one of the most heavily regulated industries and was amongst the first to adopt widely implemented international safety standards.

Regulations concerning shipping are developed at the global level. Because shipping is inherently international, it is vital that shipping is subject to uniform regulations on matters such as construction standards, navigational rules and standards of crew competence. The alternative would be a plethora of conflicting national regulations resulting in commercial distortion and administrative confusion which would compromise the efficiency of world trade.

 

IMO headquarters London

The shipping industry is principally regulated by the International Maritime Organization (IMO), which is the London based United Nations agency responsible for the safety of life at sea and the protection of the marine environment. The International Labour Organisation (ILO) is also responsible for the development of labour standards applicable to seafarers worldwide.

IMO has adopted a comprehensive framework of detailed technical regulations, in the form of international diplomatic conventions which govern the safety of ships and protection of the marine environment. National governments, which form the membership of IMO, are required to implement and enforce these international rules, and ensure that the ships which are registered under their national flags comply.

The level of ratification and enforcement of IMO Conventions is generally very high in comparison with international rules adopted for shore based industries.

The principal responsibility for enforcing IMO regulations concerning ship safety and environmental protection rests with the flag states (i.e. the countries in which merchant ships are registered – which may be different to the country in which they are owned).

Flag states enforce IMO requirements through inspections of ships conducted by a network of international surveyors. Much of this work is delegated to bodies called classification societies.

However, flag state enforcement is supplemented by what is known as Port State Control, whereby officials in any country which a ship may visit can inspect foreign flag ships to ensure that they comply with international requirements. Port State Control officers have the power to detain foreign ships in port if they do not conform to international standards. As a consequence, most IMO regulations are enforced on a more or less global basis.

October 13, 2020 IMO

On 1 January 2020, a new global cap by the IMO on sulphur content in marine fuels will come into effect. The new regulations, known as IMO 2020, mandates a maximum sulphur content of 0.5% in marine fuels globally.  The driver of this change is the need to reduce the air pollution created in the shipping industry by reducing the Sulphur content of the fuels that ships use. The impact of the new regulations on Africa will be profound given the mix of lower and higher Sulphur in oil production across the continent.

Many industry experts and researchers have written on the impact of the regulations from various perspectives with very little detail on the impact on Africa. PwC Nigeria in partnership with Energex Partners and Downstream Advisors Inc. has developed a report examining the impact of the regulation on Africa in detail considering key actors in the African market viz producers, refiners, consumers, governments, industries among others.

International Maritime Organization (IMO) is an agency of the United Nations which has been formed to promote maritime safety. It was formally established by an international conference in Geneva in 1948, and became active in 1958 when the IMO Convention entered into force (the original name was the Inter-Governmental Maritime Consultative Organization, or IMCO, but the name was changed in 1982 to IMO). IMO currently groups 167 Member States and 3 Associate Members.IMO ship pollution rules are contained in the “International Convention on the Prevention of Pollution from Ships”, known as MARPOL 73/78. On 27 September 1997, the MARPOL Convention has been amended by the “1997 Protocol”, which includes Annex VI titled “Regulations for the Prevention of Air Pollution from Ships”. MARPOL Annex VI sets limits on NOx and SOx emissions from ship exhausts, and prohibits deliberate emissions of ozone depleting substances from ships of 400 gross tonnage and above engaged in voyages to ports or offshore terminals under the jurisdiction of states that have ratified Annex VI.

The IMO emission standards are commonly referred to as Tier I…III standards. The Tier I standards were defined in the 1997 version of Annex VI, while the Tier II/III standards were introduced by Annex VI amendments adopted in 2008, as follows:

  • 1997 Protocol (Tier I)—The “1997 Protocol” to MARPOL, which includes Annex VI, becomes effective 12 months after being accepted by 15 States with not less than 50% of world merchant shipping tonnage. On 18 May 2004, Samoa deposited its ratification as the 15th State (joining Bahamas, Bangladesh, Barbados, Denmark, Germany, Greece, Liberia, Marshal Islands, Norway, Panama, Singapore, Spain, Sweden, and Vanuatu). At that date, Annex VI was ratified by States with 54.57% of world merchant shipping tonnage.Accordingly, Annex VI entered into force on 19 May 2005. It applies retroactively to new engines greater than 130 kW installed on vessels constructed on or after January 1, 2000, or which undergo a major conversion after that date. The regulation also applies to fixed and floating rigs and to drilling platforms (except for emissions associated directly with exploration and/or handling of sea-bed minerals). In anticipation of the Annex VI ratification, most marine engine manufacturers have been building engines compliant with the above standards since 2000.
  • 2008 Amendments (Tier II/III)—Annex VI amendments adopted in October 2008 introduced (1) new fuel quality requirements beginning from July 2010, (2) Tier II and III NOx emission standards for new engines, and (3) Tier I NOx requirements for existing pre-2000 engines.The revised Annex VI entered into force on 1 July 2010. By October 2008, Annex VI was ratified by 53 countries (including the Unites States), representing 81.88% of tonnage.

Emission Control Areas. Two sets of emission and fuel quality requirements are defined by Annex VI: (1) global requirements, and (2) more stringent requirements applicable to ships in Emission Control Areas (ECA). An Emission Control Area can be designated for SOx and PM, or NOx, or all three types of emissions from ships, subject to a proposal from a Party to Annex VI.

Existing Emission Control Areas include:

  • Baltic Sea (SOx: adopted 1997 / entered into force 2005; NOx: 2016/2021)
  • North Sea (SOx: 2005/2006; NOx: 2016/2021)
  • North American ECA, including most of US and Canadian coast (NOx & SOx: 2010/2012).
  • US Caribbean ECA, including Puerto Rico and the US Virgin Islands (NOx & SOx: 2011/2014).

Greenhouse Gas Emissions. 2011 Amendments to MARPOL Annex VI introduced mandatory measures to reduce emissions of greenhouse gases (GHG). The Amendments added a new Chapter 4 to Annex VI on “Regulations on energy efficiency for ships”.

NOx Emission Standards

The NOx emission limits of Regulation 13 of MARPOL Annex VI apply to each marine diesel engine with a power output of more than 130 kW installed on a ship. A marine diesel engine is defined as any reciprocating internal combustion engine operating on liquid or dual fuel. There are two exceptions: engines used solely for emergencies and engines on a ships operating solely within the waters of the state in which they are flagged. The later exception only applies if these engines are subject to an alternative NOx control measure.

NOx emission limits are set for diesel engines depending on the engine maximum operating speed (n, rpm), as shown in Table 1 and presented graphically in Figure 1. Tier I and Tier II limits are global, while the Tier III standards apply only in NOx Emission Control Areas.

Table 1. MARPOL Annex VI NOx emission limits
Tier Date NOx Limit, g/kWh
n < 130 130 ≤ n < 2000 n ≥ 2000
Tier I 2000 17.0 45 · n-0.2 9.8
Tier II 2011 14.4 44 · n-0.23 7.7
Tier III 2016† 3.4 9 · n-0.2 1.96
† In NOx Emission Control Areas (Tier II standards apply outside ECAs).
 

Tier II standards are expected to be met by combustion process optimization. The parameters examined by engine manufacturers include fuel injection timing, pressure, and rate (rate shaping), fuel nozzle flow area, exhaust valve timing, and cylinder compression volume.

Tier III standards are expected to require dedicated NOx emission control technologies such as various forms of water induction into the combustion process (with fuel, scavenging air, or in-cylinder), exhaust gas recirculation, or selective catalytic reduction.

Pre-2000 Engines. Under the 2008 Annex VI amendments, Tier I standards become applicable to existing engines installed on ships built between 1st January 1990 to 31st December 1999, with a displacement ≥ 90 liters per cylinder and rated output ≥ 5000 kW, subject to availability of approved engine upgrade kit.

Testing. Engine emissions are tested on various ISO 8178 cycles (E2, E3 cycles for various types of propulsion engines, D2 for constant speed auxiliary engines, C1 for variable speed and load auxiliary engines).

Addition of not-to-exceed (NTE) testing requirements to the Tier III standards is being debated. NTE limits with a multiplier of 1.5 would be applicable to NOx emissions at any individual load point in the E2/E3 cycle.

Engines are tested using distillate diesel fuels, even though residual fuels are usually used in real life operation.

Further technical details pertaining to NOx emissions, such as emission control methods, are included in the mandatory “NOx Technical Code”, which has been adopted under the cover of “Resolution 2”.

Sulfur Content of Fuel

Annex VI regulations include caps on sulfur content of fuel oil as a measure to control SOx emissions and, indirectly, PM emissions (there are no explicit PM emission limits). Special fuel quality provisions exist for SOx Emission Control Areas (SOx ECA or SECA). The sulfur limits and implementation dates are listed in Table 2 and illustrated in Figure 2.

Table 2. MARPOL Annex VI fuel sulfur limits
Date Sulfur Limit in Fuel (% m/m)
SOx ECA Global
2000 1.5% 4.5%
2010.07 1.0%
2012 3.5%
2015 0.1%
2020 0.5%
 

Heavy fuel oil (HFO) is allowed provided it meets the applicable sulfur limit (i.e., there is no mandate to use distillate fuels).

Alternative measures are also allowed (in the SOx ECAs and globally) to reduce sulfur emissions, such as through the use exhaust gas cleaning systems (EGCS), aka scrubbers. For example, in lieu of using the 0.5% S fuel (2020), ships can fit an exhaust gas cleaning system or use any other technological method to limit SOx emissions to ≤ 6 g/kWh (as SO2).

Greenhouse Gas Emissions

MARPOL Annex VI, Chapter 4 introduces two mandatory mechanisms intended to ensure an energy efficiency standard for ships: (1) the Energy Efficiency Design Index (EEDI), for new ships, and (2) the Ship Energy Efficiency Management Plan (SEEMP) for all ships.

  • The EEDI is a performance-based mechanism that requires a certain minimum energy efficiency in new ships. Ship designers and builders are free to choose the technologies to satisfy the EEDI requirements in a specific ship design.
  • The SEEMP establishes a mechanism for operators to improve the energy efficiency of ships.

The regulations apply to all ships of 400 gross tonnage and above and enter into force from 1 January 2013. Flexibilities exist in the initial period of up to six and a half years after the entry into force, when the IMO may waive the requirement to comply with the EEDI for certain new ships, such as those that are already under construction.

In April 2018, the IMO adopted an Initial Strategy on the reduction of GHG emissions from ships [3949], with a target to reduce the total annual GHG emissions by at least 50% by 2050 compared to 2008. The strategy calls for strenghtening the EEDI requirements and a number of other measures to reduce emissions, such as operational efficiency measures, further speed reductions, measures to address CH4 and VOC emissions, alternative low-carbon and zero carbon fuels, as well as market-based measures (MBM).

Other Provisions

Ozone Depleting Substances. Annex VI prohibits deliberate emissions of ozone depleting substances, which include halons and chlorofluorocarbons (CFCs). New installations containing ozone-depleting substances are prohibited on all ships. But new installations containing hydro-chlorofluorocarbons (HCFCs) are permitted until 1 January 2020.

Annex VI also prohibits the incineration on board ships of certain products, such as contaminated packaging materials and polychlorinated biphenyls (PCBs).

Compliance. Compliance with the provisions of Annex VI is determined by periodic inspections and surveys. Upon passing the surveys, the ship is issued an “International Air Pollution Prevention Certificate”, which is valid for up to 5 years. Under the “NOx Technical Code”, the ship operator (not the engine manufacturer) is responsible for in-use compliance.

In 2018, the International Maritime Organisation (IMO) received widespread support when it announced a landmark strategy to reduce shipping emissions. It outlined a plan to reduce carbon emissions intensity by at least 40 per cent compared with 2008 levels by 2030, and by at least 70 per cent by 2050, as well as reducing total emissions by 50 per cent by 2050, thereby ensuring that the international shipping industry plays its part in helping to achieve the objectives of the Paris Agreement. Reducing shipping emissions is a vital component of the fight against global climate change, yet greenhouse gas emissions from the maritime sector are increasing. According to an IMO study published last month, emissions are projected to increase by as much as 130 per cent by 2050 compared with 2008 levels if mitigation measures are not urgently put in place. This is an important issue for the global commodities trade, which is a major user of the shipping fleet. It is time to consider radical measures to close the competitiveness gap between carbon-intensive fuels and low or zero-carbon alternatives. The IMO has immense influence, for instance new rules brought in by the IMO since the beginning of the year have forced the use of shipping fuels with stricter sulphur standards, and further ship efficiency improvements are in the pipeline. We propose the IMO now use its influence to incentivise greater use of low- or zero-carbon maritime fuels. The ships in use, the fuels that power them and the related infrastructure all need to change. Trafigura believes the best way of promoting such change is through the adoption of a market-based measure that would charge a levy on carbon-intensive shipping fuels and subsidise low- and zero-carbon fuels. To this end, we have just submitted a proposal to the IMO for a partial “feebate” system to decarbonise global shipping. We propose a self-financing system where a levy is charged on the use of fuels with a CO2-equivalent intensity above an agreed benchmark level, and a subsidy is provided for fuels with a CO2-equivalent profile below that level. It is now time to put a price on carbon emissions in the shipping industry Our own in-depth analysis and commissioned independent research indicates that the levy should be between $250-$300 per tonne of CO2-equivalent. While primarily bridging the cost gap between carbon intensive and low or zero carbon fuels, this partial “feebate” would also raise billions of dollars for research into alternative fuels and could help assist small island developing states and other developing countries mitigate the impact of climate change. The idea of taxing carbon in shipping is not new. Indeed, the European Commission has just put forward a proposal to include shipping in its emission trading system as part of updated climate goals. But our approach builds on a number of proposals from the shipping industry including that the IMO establish a research and development programme financed by a global tax of $2 per metric tonne of bunker fuel. Our proposal is different in that it would create a genuine market-based measure — a partial “feebate” system — to reduce emissions, together with funding for R&D and for climate change-affected small island developing states. The carbon levy would need to be adjusted as economies of scale are found in the production of lower-carbon fuels and the cost competitiveness gap narrows.

Every Tuesday and Thursday, direct to your inbox, Energy Source brings you essential news, forward-thinking analysis and insider intelligence. Sign up here. The initial levy of between $250-$300 per tonne of CO2 equivalent may sound high, but we believe it is necessary. As one of the world’s largest charterers of vessels, responsible for more than 4,000 voyages each year, we recognise that a carbon levy will have an immediate effect on shipping costs which companies — including ours — would bear. This increase in operational costs will spur charterers to change behaviour to reduce emissions, charter more efficient ships and switch to lower carbon fuels. Great efforts have been made in recent years through the Global Maritime Forum, the Getting to Zero Coalition and through other initiatives to create awareness, develop solutions and catalyse a modern maritime sector to take responsibility for its climate impact. It is now time to put a price on carbon emissions in the shipping industry in the form of a global, mandatory industry levy.

In 2016, the IMO set out new mandatory requirements on electronic data interchange, stating that national authorities have until April 2021 to establish systems for the electronic exchange of information to assist ship clearance processes.

Many port states have already established such systems (maritime single windows) for the exchange of so-called administrative data. However, also port operational data, like notifications and timestamps, as well as nautical data, are part of such exchange of data, which in combination will pave the way for more efficient port operations.

“The software platforms which link ship and shore communication may differ on national levels, and therefore, we should call for international guidelines for the electronic data interchange, using common standards. This is to ensure that all actors in the port process make use of an identical data structure and common interfaces when exchanging information,” says Jeppe Skovbakke Juhl, Manager, Maritime Safety and Security, adding,

“With more than 95,000 ships operating nationally and internationally between approximately 9,000 ports, globally agreed methods and standards to interact and interface are prerequisites for maritime digitalization to succeed.”

Proposal on the table from BIMCO

For FAL 44, BIMCO has co-authored a proposal (FAL 44/18/2) for developing international guidelines for the electronic interface between ship and shore, and for all actors in the port call operation.

The proposed guidelines will ensure interoperability between port stakeholders and ships and facilitate electronic interaction between ports worldwide. This will optimise the efficiency of both ports and ships, and in turn, benefit the global supply chain.

“Although a bit technical, such guidelines should provide the necessary information on authentication of the users, integrity and confidentiality, but also include technical requirements. This could be service interface descriptions, data structures used by the service(s), dynamic behaviour of the service(s) and sequence of operations. This also covers technical issues like choice of protocols and technology for data exchanges, taking due consideration of international standards developments,” Juhl explains.

“A positive side effect of the COVID-19 pandemic is that we have been forced to re-examine our daily routines in shipping, taking a gigantic leap forward by establishing digital solutions. The IMO framework is a huge step forward for harmonising the machine-to-machine data exchange communication,” Juhl says.

Timing is extremely important to avoid local or regional standards being implemented. Therefore, BIMCO also calls for the establishment of a robust roadmap and time plan for the completion of an electronic information exchange framework in general, allowing all stakeholders to aligning national projects with the IMO progress. The schedule should also include completion of IMO reference data model and guidance.

Key to the balance of plant equipment in the engineroom, pumps are enablers of broad technological trends in shipping. Recent pump technology and application has sought to satisfy requirements for efficiency, fuel flexibility, exhaust gas cleaning system duty, and the use of sulphur cap-compliant fuels.

Since fuel costs can account for more than half of ship operating cost, efficiency has always been a driver in pump innovations. But with new measurable efficiency indices in place to drive down carbon emissions, pumps are contributing to achieving that goal, too.

The efficiency of engineroom pumps can vary by as much as 10 percentage points, says Desmi key account manager John Nielsen. He adds that although space is at a premium on board, prioritising efficiency in piping design and other engineroom infrastructure can greatly offset upfront sacrifices with savings in future. “Too often, we see corners cut in piping design, and it can seem easy to save money by choosing cheaper, smaller-diameter pipes for your newbuild,” says Mr Nielsen. “But, over time, higher pressure in the pipes reduces the lifetime of both the piping and the associated equipment, resulting in much higher long-term costs by way of unnecessary maintenance or even loss of equipment. Cavitation, for example, can demand early replacements, which could be avoided by choosing the optimal pipe sizes during installation,” he adds.

“Higher pressure in the pipes reduces the lifetime of both the piping and the associated equipment”

Mr Nielsen cites a recent Green Ship of the Future study to show that pumps can play a significant role in achieving IMO efficiency mandates, and discusses the DESMI OptiSave pump/fan control system that can optimise pump and fan operating speeds. In times of slow steaming and engine derating, pump operational profiles can be optimised to sync with the overall vessel operational profile, so they do not have to work harder than they have to. Mr Nielsen, though, warns that many shipowners are still lukewarm about leveraging new technology to boost overall plant efficiency through pumping technology. He says familiarity with old designs is often the overriding selection criterion.

Scrubber pumps

Meanwhile, the scrubber market may have ground to a standstill due to the Covid-19 pandemic and the low cost of compliant fuels, but Iron Pump is gearing up with new products for an expected second wave of scrubber demand.

The first wave of scrubbers was dominated by retrofits, which meant varying project parameters. Moving the scrubber pump from one deck to another, as may be required for a particular retrofit, may change the power requirement for the pump significantly, which has an impact on first and service costs. Scrubber capacity regulation during operation is a challenge and it directly impacts control of the scrubber centrifugal pump. Parallel operation of two or more pumps requires optimal programming of the frequency controls because the work has to be divided among the pumps. The second wave of scrubber pump selection and operation will incorporate lessons from the first wave.

Pumps need fuel flexibility

Among the promising pathways for decarbonisation of shipping is the use of renewable energy to power processes that produce carbon-neutral fuels. While the phasing in of these fuels will take several decades, ships that are being built this decade will likely see decarbonisation. With the ability to meet current IMO emission standards and significantly reduce NOx emissions up to 85% and CO2 emissions by 20%, liquefied natural gas (LNG) is touted as a transition fuel. This would mean equipment and systems used in ships coming out of yards today may need to handle a different set of fuels in the future. This calls for greater fuel flexibility in equipment.

In 2016, Svanehøj launched a new deepwell fuel pump for gas. The Svanehøj DW Fuel Pump has been developed for LNG, but it is fully compatible with other liquid gas fuels, such as ethane and LPG, as well as synthetic carbon-free electrofuels, such as ammonia and synthetic natural gas (SNG).

The Svanehøj DW Fuel Pump is a long-shafted cryogenic deepwell, multistage centrifugal pump designed for continuous operation with variable-speed drive. All electrical components, including the motor, are situated outside the tank, which means that excessive heat from the motor does not increase boil-off gas and pressure in the tank. The pump is built with a five-year/25,000-hour service interval, and maintenance is made easy with bearings situated outside the tank. The motor and outer Magdrive can be removed and serviced at any time. When the static seal is active, the main bearing and inner Magdrive can be serviced, even with gas in the tank. The pump can be installed in a caisson pipe with a retraction system, which enables pumps to be extracted for maintenance, even with liquid gas in the fuel tank. The pump can be lifted in one piece or in sections of 700 mm.

The technological changes brought about by the sulphur content rules extend to fuel-handling systems such as fuel pumps. Sulphur is important for the lubrication quality of fuels. Low viscosity and poor lubricity may damage the fuel pump. Compliant low sulphur residual fuels have poor lubricity, and the quality of fuel varies with the blend and the bunker supplier.

Screw pumps used for fuel pumping in the engineroom need lubricity of the pumped medium to reduce friction, especially at high pressures. Two types of wear may result in low sulphur fuels: adhesive and abrasive wear. Adhesive wear may lead to scratches, grooves, scoring and the formation of crests on the screws. When adhesive wear reaches a certain point, the pump drive can no longer move the screw against the surface of the pump housing.

Abrasive wear leads to material removal mainly in the screw bores. This increases the internal backflow, and the pump can no longer maintain the required system pressure. The pump runs, but the flow rate significantly decreases.

To prevent this, the surface hardness of the pump components can be increased. Due to the high process temperatures, certain hardening processes can lead to distortion of the components, which is impossible to correct, rendering the components unusable.

Screw-pump manufacturer Kral has a simple solution to abrasive wear. It applies a binding coating to the metal screws used in Kral pumps. Through this coating the screws receive a strongly hardened surface with much less friction.

The friction coefficient of the coated screws in Kral pumps is reduced by a factor of 10. At the same time the screw surface achieves a high degree of hardness.

Some 400,000 seafarers from across the globe are now stranded on ships, continuing to work but unable to be relieved, in a deepening crew change crisis which threatens trade and maritime safety.

During a high-level event on the margins of the United Nations General Assembly (24 September), Captain Hedi Marzougui, who was in command of a vessel between December 2019 and May 2020, appealed to Governments to act to allow seafarers to come home.

“Not knowing when or if we will be returning home brings a severe mental toll on my crew and myself,” Captain Marzougui said. “I would encourage each and every one of you to think of how you would feel, if you had to work every day, for 12 hours, with no weekends, without seeing your loved ones, and trapped at sea. Now add that you have to do that with no idea of when you will be repatriated.”

Captain Hedi Marzougui joined UN chiefs in appealing to Governments to act to allow stranded seafarers to come home.

The COVID-19 pandemic restrictions on travel and transit have severely impacted on seafarers.  Despite multiple pleas to Governments to designate them as essential key workers and to facilitate their travel, the number of seafarers whose contracts have been extended by several months has continued to increase. Some seafarers have now been at sea for 17 months without a break, well beyond the 11-month limit set out in the Maritime Labour Convention (MLC). Besides the 400,000 seafarers stuck at sea, another 400,000 are unable to join ships.

This threatens the fundamentals of ship safety standards which the International Maritime Organization (IMO) has worked to develop over six decades, IMO Secretary-General Kitack Lim (download speech here) told the online event, which brought together leaders from major global businesses, the maritime industry, government, the UN and unions.

“Overly fatigued and mentally exhausted seafarers are being asked to continue to operate ships,” Mr. Lim said. On more than 60,000 cargo ships which continue to deliver vital goods, foods and medicines, ship safety is hanging in the balance, just as seafarers’ lives are being made impossible. The safety of navigation is in peril.”

Secretary-General Lim restated his plea to Governments: “Action is needed – and is needed now. We all depend on seafarers. They should not be the collateral victims in this pandemic. Seafarers deliver for us – and now we need to deliver for them.”

In a statement read out at the event, to mark World Maritime Day 2020, UN Secretary-General António Guterres reiterated his concern for seafarers stranded at sea. He renewed his appeal to Governments “to address their plight by formally designating seafarers and other marine personnel as ‘key workers’, ensuring safe crew changes and implementing the protocols developed by UN agencies, as well as the International Chamber of Shipping and the International Transport Workers’ Federation, allowing stranded seafarers to be repatriated and others to join ships.”

In a letter issued to the UN Secretary General, the CEOs of 30 Consumer Goods Forum companies, including Unilever and Danone, have called on governments to designate seafarers as “key workers” and raised strong human rights concerns, stating: “the situation has also inadvertently created a modern form of forced labour”.

Unilever’s Chief Supply Chain Officer Marc Engel said COVID safe crew changes were needed without delay. “When the ships stop, so does everything else. We are now close to an entirely avoidable breaking point which could ripple out through the economy. Even a temporary interruption could push companies and countries over the edge,” he said. Ms. Henriette Hallberg Thygesen, VP and CEO, Fleet and Strategic Brands at A.P. Moller-Maersk echoed the call for words to be followed by action.

Sanda Ojiambo, CEO and Executive Director of the UN Global Compact, the world’s largest corporate sustainability initiative, encouraged businesses to call on governments to end the labour abuses that seafarers are suffering, noting that the Ten Principles of the UN Global Compact represent pillars of responsible business which “are connected to the humanitarian, economic and safety crisis unfolding on our seas.”

Both Guy Platten, Secretary-General of the International Chamber of Shipping and Stephen Cotton, General Secretary of the International Transport Workers’ Federation called on governments to intervene to end the crew change crisis, warning the numbers of seafarers impacted would only continue to increase without coordinated action by governments.

ILO Director General Guy Ryder called on governments to implement urgent and pragmatic solutions that fully respect seafarers’ rights. “Seafarers are exhausted and simply cannot continue working on board indefinitely,” Mr. Ryder said.

Transport and maritime ministers from Canada, France, Kenya, Panama and the Philippines also addressed the virtual event. They urged other Governments to join them in designating seafarers as essential workers, implementing measures for safe crew change and facilitating COVID-safe transit for seafarers.

The meeting was convened by the UN Global Compact, the International Maritime Organization and the International Labour Organization, in collaboration with the International Chamber of Shipping and the International Transport Workers’ Federation.

The International Chamber of Shipping (ICS), which represents the world’s national shipowners’ associations and more than 80% of the world merchant fleet, has published its Annual Review for 2020. The Review covers a broad cross-section of issues in which ICS is engaged on behalf of the global shipping industry.

The Review explores, in depth, the significant issues faced by the industry in 2020, including:

  • The impact of COVID-19 and the intensifying crew change crisis – COVID-19 related restrictions on travel and the ability to rotate crew, leaving 400,000 seafarers stranded at sea.
  • Efforts to decarbonise shipping, including the ongoing negotiations at the UN International Maritime Organization (IMO) and the radical industry proposal for a USD 5 billion fund to accelerate the R&D of zero-carbon technologies.

This year’s Review offers a comprehensive analysis of ICS’s activities across a wide range of subjects. This includes: piracy in West Africa and the continuing migrant crisis in the Mediterranean; supporting the successful implementation of the IMO 2020 Sulphur Cap and the IMO Ballast Water Management Convention; defending the global pollution liability regime; and pushing for a fundamental review of the STCW Convention on seafarers’ training standards.

The Review is of interest to anyone involved with international shipping, including shipping companies, maritime administrations and policymakers. A full copy of the Annual Review can be downloaded here.

Speaking on the publication of the Annual Review, Esben Poulsson, ICS Chairman said:

“For the global shipping industry, 2020 is a year that will be long remembered. As remarked in this year’s Annual Review, the COVID-19 pandemic has led to significant disruptions to the industry’s way of working. ICS continues to be at the forefront of addressing the ongoing crew change crisis, making every effort to persuade governments to facilitate the repatriation of 400,000 seafarers stranded at sea.”

“While much of this Review necessarily focuses on COVID-19, the vital work of ICS continues, representing the global industry with its global regulators.

“This includes critical work on the reduction of the industry’s CO2 emissions, to which ICS remains fully committed. Last December, ICS, along with industry partners, proposed the establishment of a USD 5 billion global R&D fund dedicated to zero-carbon technologies. Support from governments for this bold initiative will be critical if we are to deliver on the ambitious IMO objective to at least halve total emissions from shipping by 2050.”

“As we move into ICS’s centenary year, which will hopefully be far less challenging than 2020, there is still much work for ICS to do in helping to shape the future of shipping.”
