International classification society DNV GL has developed the GAS READY class notation that gives owners, who at the new building stage want to prepare their vessel for a potential conversion to LNG operation after delivery, a useful framework for contracting.
It provides a picture of the level of LNG fuelled preparedness of their vessel, as well as guidance on the scope of the contemplated work to all involved parties.
“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”, says Torill Grimstad Osberg, DNV GL Head of Section for LNG Cargo Handling & Piping systems .
“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.”
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.
The owner can also 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.
In 2014 the industry hit a significant milestone with over 120 LNG fuelled ships in operation or on order worldwide (excluding LNG carriers).
