The American Bureau of Shipping (ABS) has awarded a certificate of general design approval (GDA) to an LNG fuel tank design developed by South Korea's Hyundai Heavy Industries (HHI).
The new design is compliant with International Maritime Organisation (IMO) Type B requirements, and has been developed to help reduce the loss of cargo space, as well as enable more effective use of a vessel's onboard space.
ABS' proposed tank can be used to power gas-fuelled vessels and is based on a 14,500 twenty foot equivalent unit (TEU) containership design. It can also be customised for use in other ship types and sizes.
ABS chairman, president and CEO Christopher Wiernicki said: “We are pleased to issue this approval that represents our involvement in the expanding gas fuel market and further promotes the adoption of LNG as fuel.
“As a technology leader, ABS works collaboratively with project stakeholders to evaluate new innovations and navigate the associated safety challenges.”
ABS also noted that the tank design is in compliant with the society’s relevant rules and guides, as well as the International Code of Safety for Ships using Gases or other Low-Flashpoint Fuels (IGF Code).
Hyundai Heavy Industries senior executive vice-president Yunsik Lee said: “Working with ABS as our advisor, we were able to prove and determine the feasibility of our Type B fuel tank design concept.
“Together, we applied the latest safety standards to the design, bringing us closer to incorporating this innovative fuel tank design into new containerships.”
The company currently provides various solutions for the shipbuilding, offshore and engineering sectors.
