Russian Maritime Register of Shipping has released its Q3 2026 regulatory update for partners and clients, summarizing new requirements of the International Maritime Organization (IMO) and the International Association of Classification Societies (IACS) entering into force after July 1, 2026.
Key IMO regulatory developments:
July 1, 2026 – amendments to the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) enter into force.
Paragraph 16.9 – Alternative fuels and technologies – addresses the possibility of using toxic cargo as fuel, subject to special approval by the Administration. The amendments apply to new and existing 2G/2PG ships carrying cargoes defined as toxic products in the IGC Code and subject to the Code.
September 1, 2026 – amendments to the NOx Technical Code 2008 enter into force.
A procedure is established for the re-certification of already installed engines that have undergone substantial modification. This applies to any marine diesel engine with a power output over 130kW which undergoes a substantial modification, or is to be certified to a NOx Tier to which it was not certified at the time of certification, therefore requiring recertification.
Key IACS regulatory developments:
July 1, 2026 – IACS UR Z15 (Rev.4 Jan 2025) enters into force. IACS decided that the requirements of UR Z15 could be applied not only to mobile offshore drilling units but also to other units. Necessary changes were made to existing requirements, e. g., deletion of the word “drilling”, addition of the term “other similar units”.
July 1, 2026 – IACS UI SC73 (Rev.3 Dec 2025) enters into force.
Revision 3 of UI SC73 provides a unified interpretation of SOLAS regulation II2/20.6.3.1 relating to portable fire extinguishers on weather decks used as ro-ro cargo spaces. The UI was revised to remove elements what were clarified by the adoption of SOLAS amendments in resolution MSC.550(108) and to align with the unified interpretation in MSC/Circ.1120.
