Marine methanol fuel engine

1 Scope

GB/T 47317-2026 is the Chinese national standard covering the marine engine burning methanol - one of the few alternative fuels that is liquid at ambient conditions, with the fuel system materials, the pilot ignition, the emissions and the safety of a fuel that is toxic and burns invisibly. Methanol has become the fuel a large share of new container ship orders are specified for. First edition, in force since 1 July 2026, with the road counterpart GB/T 47585-2026. It was issued on 31 March 2026 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the classification, models, and test methods for marine methanol-fueled engines (hereinafter referred to as "engines"), and specifies the engine... Technical requirements, inspection rules, marking, packaging, transportation and storage. This document applies to the design, manufacture, testing, and acceptance of marine methanol-fueled engines.
