Jiangnan Gets AiP for LNG Bunker Vessel Design

 Chinese shipbuilder Jiangnan Shipyard has received an Approval in Principle (AiP) from Lloyd’s Register for its 7,500 m3 LNG bunker vessel (LBV) design at this year’s Gastech, taking place in Barcelona, Spain.

The vessel is intended to supply gas for ships using LNG as fuel in support of the rapid growth of LNG fuel demand in the marine market, connected to the approaching global sulphur 2020 limit.

“The 7,500 m3 LBV has a compact design that is compatible with quays and ships, a well-developed hull to reach economical speed-power performance. 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,” Hu Keyi, Jiangnan Technical Director, said.

The vessel is equipped with two IMO type C LNG tanks and a modern cargo handling system.

“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,” David Barrow, LR Commercial Director – Marine & Offshore, commented.

This design is a member of the LNGRELAY family, the 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.

Separately, Jiangnan has secured AIP from ABS for its LNG Jumbo, 175,000 cbm Mark III Flex LNG carrier.

The “LNG JUMBO” design specifies a WINGD X-DF low-pressure, low-speed two-stroke dual-fuel main engine propulsion system that meets IMO NOx Tier III requirements without the need for exhaust gas treatment systems. The design also includes a United States Coast Guard (USCG) certified ballast water treatment system.
