This new design is just one of the fruits of the ClassNK Hanjin relationship

ClassNK has issued Approval in Principle (AIP) for a 7,500 cbm LNG bunkering vessel designed by Hanjin Heavy Industries & Construction Co Ltd.

The revolutionary design is the result of joint research carried out by Hanjin Heavy Industries & Construction Co Ltd and ClassNK to improve the efficiency of LNG bunkering vessels.

Takashi Nishibashi, ClassNK’s Country Manager of Korea said: “Hanjin Heavy Industries & Construction Co Ltd. and ClassNK have always enjoyed close cooperation, and this design is just one of the fruits of our relationship. We hope this AIP will help pave the way for a new generation of highly efficient LNG bunkering vessels.”

Cha-Soo Lee, technical director of Hanjin Heavy Industries & Construction Co Ltd added that the new design is the best compromise which deals with the challenges of compact ship’s dimensions, robust hull structure, more cargo capacity, simple operation and lower ship price.

Currently, LNG fuelled vessels are largely dependent on existing infrastructure comprised mainly of fixed bunker locations, potentially limiting their operations.

The new design recognises the greater flexibility that LNG bunker vessels could provide through ship-to-ship bunkering.

It employs type-C bi-lobe tanks, improving on cargo capacity to allow for greater efficiency and productivity.

The AIP was granted after confirming the design complies with ClassNK’s Rules and Guidance for the Survey and Construction of Steel Ships.

Compliance will allow the design to be considered for further individual projects, where tests on the hull structure scantling and direct stress analyses will be carried out to ensure the structural integrity of each specific design.
