Spanish engineering and technology group Sener has been granted an approval in principle (AiP) by DNV GL for its LNG-fueled bunkering vessel designs.
The company noted in its statement the design was in compliance with DNV GL class rules as well as the current and upcoming regulations, including the new emission control regulations and the IGF Code for fuel with a low flashpoint.
Two separate AiPs have been issued, covering the new design of the Sener LNG bunkering vessels (LBV) family which consists of a small unit having a bunker capacity of 4,000 cubic meters and a bigger unit with a bunkering capacity of 8,000 cubic meters.
Rafael de Góngora , general manager of marine at Sener, said, “LNG is emerging in several ship sectors and has a great potential but should be accomplished by the necessary port facilities and infrastructure capable of providing a quick and efficiency gas refueling, in which LNG bunkering vessels will play an important role.”
Sener adds that apart from the traditional focus points like the hull structure and stability, the approval process paid special attention to the innovation in the design related to cargo handling (liquid and vapor), hazardous zones and risk assessment, mooring arrangement and quick release, manifold, transfer arms and hoses as well as boil-off.
