ABS Approves New MOSS-type LNG Tank Concept
ABS issues Approval in Principle for KHI’s non-spherical shaped MOSS-type LNG tank.
ABS, a leading provider of classification and technical services to the marine and offshore industries, granted Approval in Principle (AIP) for a new MOSS-type LNG tank design concept developed by Japan’s Kawasaki Heavy Industries (KHI).
“We are pleased to issue this AIP that further demonstrates our commitment to technology advancements and safety,” says ABS Vice President for Global Gas Solutions Patrick Janssens. “KHI’s concept applies the latest technologies, introducing new efficiencies and innovations that promote a safer and more sustainable shipping industry.”
Designated as an IMO Type B independent tank, this concept takes a new approach by applying a non-spherical tank design to increase the use of space on board an LNG carrier. According to KHI, the non-spherical design concept allows Panamax-size LNG carriers to expand their total carrying capacity to 180,000m³, a 25,000m³ volume increase when compared to using spherical tanks. In issuing its AIP, ABS reviewed the strength and fatigue analysis to support KHI in demonstrating the feasibility of the new concept.
“As the Panama Canal expands and LNG demand increases, owners and operators are looking to gain efficiencies without compromising safety,” says KHI Ship & Offshore Company General Manager for the Engineering Division Hideaki Naoi. “This new concept adds 15% more carrying capacity while maintaining the size of the new Panamax tankers. By working with a proven technology leader like ABS, we were able to prove the feasibility of this innovative design.”
Recognizing the changing landscape and increased industry focus on gas, ABS launched its Global Gas Solutions team in 2013 to support industry in developing gas-related projects. The ABS Global Gas Solutions team provides industry leadership, offering guidance in liquefied natural gas (LNG) floating structures and systems, gas fuel systems and equipment, gas carriers, and regulatory and statutory requirements. ABS has extensive experience with the full scope of gas-related assets and is the classification society of choice for some of the most advanced gas carriers in service.
