Wärtsilä’s LNGPac System: AIP Certificate SMM Presentation

The new Wärtsilä LNGPac, the upgraded version of the company's successful LNG fuel handling system, has been granted an AIP (Approval in Principle) Certificate from the classification society DNV GL. The certificate will be presented at the Wärtsilä stand in Hall A4, Booth 305 at the SMM conference and exhibition in Hamburg, Germany, 9 September.

The AIP Certificate covers Wärtsilä's innovative improvements to the original LNGPac. The new solution has removed the heating media skid and its pumps, and includes an improvement to the Wärtsilä Cold Recovery solution. The certificate is based on technical material and safety analyses, and includes documentation concerning normal operation of the system and a presentation of risk scenarios. In effect it means that the system is judged to be safe and reliable and that it will be approved by classes in actual projects.

"This is an important step in making this new feature of the Wärtsilä LNGPac available to the marine market, and represents an expected verification of the technical aspects that have gone into the development of this system," says Jaakko Eskola, Senior Executive Vice President & President, Ship Power, Wärtsilä Corporation.

"The presentation of this approval in principle marks another chapter in a longstanding and successful cooperation between Wärtsilä and DNV GL. The development of the first LNGPac and its installation onboard the Bit Viking, the first LNG conversion of a vessel in service, were milestones in the uptake of LNG as a ship fuel, and this upgraded LNGPac is another significant step forward," says Dr Gerd-Michael Würsig, DNV GL Business Director for LNG fuelled ships.

"As DNV GL's experience with LNG has grown over the years, so too has our conviction that LNG can make a significant and positive contribution to the efficiency and sustainability of the maritime industry as a whole. To keep this momentum for the use of LNG as a ship fuel, DNV GL will continue to work with partners like Wärtsilä to ensure that owners and yards can be confident that this technology meets strict safety and reliability standards," he added.
