1 June 2022

Adopted by MEPC 75: 

Amendments to BWM Convention 

• Amendments to the International Maritime Dangerous Goods Code (IMDG Code) (amendment 40-20) related to segregation requirements for alcoholates; segregation in relation to liquid organic substances; classification and transport of carbon, following incidents involving the spontaneous ignition of charcoal; classification of UN portable tanks for multimodal transport; and provisions for labels.

• Entry into force of  Revised MARPOL Annex VI  – including carbon intensity measures (requirements for ships to calculate their Energy Efficiency Existing Ship Index (EEXI) following technical means to improve their energy efficiency and to establish their annual operational carbon intensity indicator (CII) and CII rating – read more)
• Entry into force of amendments to MARPOL Annex I (addition of a new regulation 43A) to introduce a prohibition on the use and carriage for use as fuel of heavy fuel oil (HFO) by ships in Arctic waters on and after 1 July 2024. The prohibition will cover the use and carriage for use as fuel of oils having a density at 15°C higher than 900 kg/m3 or a kinematic viscosity at 50°C higher than 180 mm2/s. Ships engaged in securing the safety of ships, or in search and rescue operations, and ships dedicated to oil spill preparedness and response would be exempted. Ships which meet certain construction standards with regard to oil fuel tank protection would need to comply on and after 1 July 2029. A Party to MARPOL with a coastline bordering Arctic waters may temporarily waive the requirements for ships flying its flag while operating in waters subject to that Party’s sovereignty or jurisdiction, up to 1 July 2029.
• Entry into force of amendments to  MARPOL Annexes I and IV concerning the exemption of UNSP barges from survey and certification requirements. The amendment specifies that the Administration may exempt a UNSP barge from the annual survey and certification requirements, for a period not exceeding 5 years provided that the UNSP barge has undergone a survey to confirm that certain conditions are met. The amendments also provide the form for the International Oil Pollution Exemption Certificate for Unmanned Non-self-propelled Barges.

• Amendments to the IMO Convention for the Control of Harmful Anti-fouling Systems on Ships (AFS Convention), to include controls on the biocide cybutryne. Ships shall not apply or re-apply anti-fouling systems containing this substance from 1 January 2023. Ships shall remove or apply a coating to AFS with this substance at the next scheduled renewal of the anti-fouling system after 1 January 2023, but no later than 60 months following the last application to the ship of an anti-fouling system containing cybutryne.

• Amendments to the appendix to the annex to the 1974 SOLAS, concerning the addition of a footnote to Forms C, E and P in the Records of Equipment.
• Amendments to chapter 15 of the International Code for Fire Safety Systems (FSS Code), relating to inert gas systems.
• Amendments to parts A and A-1 of the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), including those relating to regulations on loading limit for liquefied gas fuel tanks, regulations for fuel distribution outside of machinery space, regulations for internal combustion engines of piston type and fire protection for fuel storage hold space; and amendments relating to the protection of the fuel supply for liquefied gas fuel tanks, aimed at preventing explosions.
• Amendments to chapters IV and VI of the International Life-Saving Appliance Code (LSA Code), relating to general requirements for lifeboats and launching and embarkation appliances.

Adopted by MSC 102: safe mooring  

• Amendments to chapter II-1 of the International Convention for the Safety of Life at Sea (SOLAS), related to towing and mooring. The amendments to SOLAS regulation II-1/3-8 (Towing and mooring equipment), require appropriate and safe-to-use designs of mooring arrangements, and introduce a maintenance and inspection regime, as well as proper documentation. Related  guidelines were also adopted, covering the design of mooring arrangements and the selection of appropriate mooring equipment and fittings for safe mooring; and inspection and maintenance of mooring equipment including lines; as well as revised guidance on shipboard towing and mooring equipment.
• Amendments to parts B-1, B-2 and B-4 of SOLAS chapter II-1 related to watertight integrity requirements. The amendments are expected to enter into force on 1 January 2024.
• Amendments to the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code),  related to the fuel containment systems, fire safety, welding of metallic materials and non-destructive testing.
• Amendments to the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code), related to welding procedure tests for cargo tanks and process pressure vessels.

Adopted by MSC 103:

• New SOLAS regulation II-1/25-1, requiring water level detectors on multiple hold cargo ships other than bulk carriers and tankers.
• Amendments to SOLAS regulation III/33 and the LSA Code, aiming to remove the applicability of the requirements to launch free-fall lifeboats to test their strength with the ship making headway at speeds up to 5 knots in calm water on cargo ships of 20,000 GT and above.
• Chapter 9 of the International Code for Fire Safety Systems (FSS Code), relating to fault isolation requirements for individually identifiable fire detector systems installed, in lieu of section identifiable fire detector systems on cargo ships and passenger ship cabin balconies; and clarifying the acceptability of less complex and costly section identifiable fault isolation for individually identifiable fire detector system on cabin balconies; and clarifying the acceptability of less complex and costly section identifiable fault isolation for individually identifiable fire detector systems.

Adopted by MSC 104:

• Entry into effect of amendments to MARPOL Annex I (addition of a new regulation 43A) to introduce a prohibition on the use and carriage for use as fuel of heavy fuel oil (HFO) by ships in Arctic waters on and after 1 July 2024. The prohibition will cover the use and carriage for use as fuel of oils having a density at 15°C higher than 900 kg/m3 or a kinematic viscosity at 50°C higher than 180 mm2/s. Ships engaged in securing the safety of ships, or in search and rescue operations, and ships dedicated to oil spill preparedness and response would be exempted. Ships which meet certain construction standards with regard to oil fuel tank protection would need to comply on and after 1 July 2029. A Party to MARPOL with a coastline bordering Arctic waters may temporarily waive the requirements for ships flying its flag while operating in waters subject to that Party’s sovereignty or jurisdiction, up to 1 July 2029.
