DNV GL has announced a new "GAS READY" notation, which aims to give shipowners a useful framework for future-proofing a vessel newbuilding for potential conversion to LNG post-delivery.
The notation provides a clear picture of the level of LNG-fuelled preparedness of a vessel, as well as guidance on the scope of the contemplated work to all involved parties, said the classification society.
Torill Grimstad Osberg, DNV GL's Head of Section for LNG Cargo Handling and Piping systems, said the notation was developed from the society's experience with its LNG Ready service, as well as the 50 LNG-fuelled vessels.
"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," said Mr Osberg.
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, said DNV GL.
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).
