DNV technical regulatory news: Highlights on IMO Maritime Safety Committee (MSC 106)

15 Nov 2022

Classification society DNV on Saturday (12 November) published a technical regulatory news titled ‘IMO Maritime Safety Committee (MSC 106)’.

It focuses on highlights of the 106th session of the IMO’s Maritime Safety Committee (MSC 106) held in London, UK, from 2 to 11 November.

The highlights include MSC 106 adopting amendments to SOLAS Chapter II-2 to prevent the supply of fuel oils with flashpoints lower than permitted.

Requirements to permit LNG tanks constructed from high manganese steel were also adopted, and new safety guidelines for lifting appliances and anchor handling winches were approved.

The following is an excerpt from the news update relating to bunker fuels:

Safety of ships relating to the use of fuel oil

Low-flashpoint fuels are attractive from an environmental perspective due to their clean burning characteristics and low sulphur content.

MSC 106 adopted amendments to SOLAS Chapter II-2, Regulations 3 and 4, requiring new and existing ships carrying oil fuel to be provided with a bunker delivery note, prior to bunkering, stating that the flashpoint of the actual fuel batch is in conformity with the flashpoint requirements of SOLAS. The amendments further request contracting governments to inform the IMO of cases where oil fuel suppliers have delivered fuels that do not meet the SOLAS flashpoint requirements, and to take appropriate action against oil fuel suppliers accordingly.

The amendments will enter into force on 1 January 2026.

Metallic materials for cryogenic service

MSC 106 adopted amendments to the IGC and IGF Codes to include high manganese austenitic (hi-Mn) steel for cryogenic service. The amendments permit the use of high manganese austenitic steel for type A, B and C tanks, for among others butane and methane (LNG) as cargo or fuel.


The amendments will enter into force on 1 January 2026.
