LNG: the fuel of tomorrow

DNV GL has released a new contracting framework for owners seeking to prepare their newbuild vessels for a potential conversion to LNG operation after delivery.

The GAS READY notation provides a clear picture of the level of LNG-fuelled preparedness of vessels, as well as guidance on the scope of the contemplated work to all involved parties.

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.

Torill Grimstad Osberg, DNV GL Head of Section for LNG Cargo Handling and Piping systems, said: “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 […] 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.”

Dr Gerd-Michael Wuersig, DNV GL’s Segment Director for LNG fuelled ships, added: “DNV GL’s unique LNG Ready service has been in place for over two years and has proven its value in assisting many shipowners, operators, yards and designers in identifying the most attractive compliance option for their ships. Through a detailed technical and financial feasibility study, the LNG Ready service investigates all the potential options for compliance and fuel cost reduction, uncovers any technical showstoppers, as well as calculating the financial attractiveness of each option […] The new class notation GAS READY provides a formalised framework for documenting the compliance option and preparation level chosen, and thereby is a natural extension of the LNG Ready service.”
