Classification society Lloyd’s Register (LR) has issued an Approval in Principle (AiP) for a liquefied natural gas (LNG) bunker tanker to Shanghai-based Jiangnan Shipyard, a subsidiary of China State Shipbuilding Corporation (CSSC).
Jiangnan has developed a 7,500 m3 LNG bunker vessel (LBV) design to supply gas for ships using LNG as fuel.
“The 7,500 m3 LBV has a compact design for compatibility with quays and ships, a well-developed hull to reach economical speed-power performance,” said Hu Keyi, Jiangnan Technical Director at Jiangnan.
“A dual fuel diesel-electric (DFDE) propulsion system, two azimuth thrusters and one bow thruster to provide excellent manoeuvrability and safety while in port/at anchorage.”
“Two IMO type C LNG tanks and a state-of-art designed cargo handling system are equipped onboard to provide variable means of cargo handling, boil-off gas (BOG) management and ship to ship (STS) transfer.”
The design is a member of the LNGRELAY family, a family of LNG bunker vessels with different cargo capacities developed by Jiangnan, which include a 5,500 m3 LBV, 7,500 m3 LBV, 10,000 m3 LBV, 12,000 m3 LBV, and 20,000 m3 LBV.
“LR has classed several LNG bunkering vessels and is delighted to be able to use our experience in helping industry players develop LNG Bunkering Vessel designs to support Jiangnan with this project,” notes David Barrow, LR Commercial Director – Marine & Offshore.
“Jiangnan prepared the concept design and outline specifications and LR provided assistance and support in terms of the specification review. LR also checked the design against IGC code, LR Gas Ship Rules as well as other relevant applicable standards.”
