Foreign Vessel - Liquefied Gas as Fuel Training Development

Marine inspectors will need to develop skills to prepare as a growing number of vessels elect to employ liquefied gas as fuel.

We have a workgroup in the process of developing help guides as an interim measure in the absence of standardized national tools.

Individuals both internally and externally are welcome to submit suggestions that might assist marine inspectors to perform inspections. They can include a helpful YouTube video link, or just offering a suggestion on what items you feel should be checked, why, and what to look for during an annual inspection.

In the meantime, you will see this page develop with helpful information to assist inspectors. This is not national policy, it is a starting point in the absence of national policy.

More information will be made available as we move forward.

Reach out to Scott Mercurio (See Staff Contacts) for any interest or questions you may have.

Sources of IMO Regulatory Guidance and Requirements, in order of publication date, are:

a) IMO: Resolution MSC.285(86) (2009)  Interim Guidelines on Safety for Natural Gas-Fuelled Engine Installations in Ships (2009)

Resolution MSC.285(86) is guidance prior to the IGF Code. Vessels should have additional approval to make use of LG as Fuel.

b) IMO: IGF Code (2017)  Read about the International Code of Safety for Ship Using Gases or Other Low-flashpoint Fuels (IGF Code) on the IMO website.

IGF Code (2017) is a requirement effective 01 January 2017. Vessels built since 01 January 2017 must comply with the IGF Code to make use of LG as Fuel.

The below items come directly from the Foreign Gas Carrier Foreign Examiner PQS. These PQS items serve as a great training starting point for foreign vessels using liquefied gas as fuel.

Items noted with " * " are still under discussion within the work group. Some items may be added, some itmes may be deleted.
