The Methanol Institute has welcomed the decision of the IMO MSC 99 in June to invite the International Organization for Standardization (ISO) to develop a standard for methyl/ethyl alcohol as a marine fuel and a standard for methyl/ethyl alcohol fuel couplings. The decision is expected to provide a pathway for very low carbon fuels in future, the Institute noted.
The global chemicals industry currently relies on the IMPCA specification for producers and consumers but a dedicated ISO standard will help shipowners understand the fuel in a marine fuel context. We are seeing increasing interest around Methanol as a liquid fuel that is safe to handle easy to ship and store and is more widely available than other low sulphur alternatives,
…said MI Chief Operating Officer Chris Chatterton.
There are currently eight ships trading internationally operating on methanol as fuel – the ropax ‘Stena Germanica’ and seven tankers operated by Waterfront Shipping, with at least four more expected to enter into service in 2019.
Several recent research projects, including a research under the Sustainable Marine Methanol (SUMMETH) project, have independently confirmed Methanol’s suitability as a suitable replacement for conventional marine fuels in coastal, inland and short sea sectors.
ISO will work to develop the standards and provide them as soon as possible, the first time it has considered these fuel types.
IBIA’s IMO Representative, Unni Einemo, said:
A comment was made during MSC 99 that fuel standards should be developed before ships begin using such low-flashpoint fuels so that safety concerns are adequately addressed before, not after, larger numbers of ships start using them. However, ISO has traditionally developed fuel standards only after user experience to be able to assess which parameters need to be specified, and also what relevant limits should be.
The decision to invite ISO to develop standards for methyl/ethyl alcohol fuel for ships was taken when MSC 99 discussed the report from the fourth session of the Sub-Committee on Carriage of Cargoes and Containers (CCC).
CCC has been tasked with drafting technical provisions for using methyl/ethyl alcohol as a ship fuel under an ongoing item on its agenda regarding amendments to the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code).
