DNV GL has developed a new ‘Gas Ready’ notation for shipowners who are looking at LNG as a possible future fuel, and are preparing their vessel for a potential conversion after delivery of a new build.

This new notation comes when the IGF Code is practically finalised and with the imminent introduction of sulphur limits and growing infrastructure and production capability for LNG as a fuel. The new notation is said to provide a clear picture of the level of LNG-fuelled preparedness of a shipowner’s vessel, as well as guidance on the scope of the contemplated work to all parties involved in a newbuild.

“We developed the new Gas Ready notation based on the experience we have gained from our LNG Ready service as well as the 50 LNG fuelled vessels we already have in class with our Gas Fuelled notation”, said Torill Grimstad Osberg, head of section for LNG cargo handling and piping systems, DNV GL.  

“This new notation enables owners to ensure that a future LNG fuelled version of the vessel complies with the relevant safety and operational requirements, while also being very useful in helping owners specify and quantify the level of investment they are making at the newbuilding stage,” he added.

The basic notation with nominators D and MEc – GAS READY (D, MEc) – verifies that the vessel is in compliance with the gas fuelled rules in terms of its overall design for future LNG fuel operations and that the main engine can be converted or operate on gas fuel.

In addition, the owner can choose to add extra optional levels to the newbuilding under the notation. These cover selections such as structural reinforcements and the choice of correct materials to support future LNG tanks (S), preparations for future gas fuel systems (P), certification and installation of LNG fuel tanks (T), and the installation of machinery, which can be converted gas fuel, or which is already capable of burning gas fuel - putting the vessel further along the LNG track and thereby speeding and simplifying a later conversion.
