Deltamarin and Brevik Technology have partnered to develop a new multigas carrier design for LNG, LPG, LEG and ethane carriers.
The concept combines the design of Deltamarin’s B.Delta and the patented cylindrical gas tanks concept of Brevik Technology.
The design involves an independent containment system built into a vessel unlike the traditional concept of building the vessel and the tanks as one entity.
Brevik Technology managing director Oystein Kristoffersen Saether said: “Up to now gas carriers have been complex and expensive to design and construct.
“This is not the case anymore as Brevik Technology has developed cylindrical steel tanks, which are separate from the vessel hull.”
The cylindrical tank design reduces stress on the vessel hull by allowing the tanks to expand in all directions.
The design promises high-speed during transit, no restrictions on cargo level in the tanks, and parallel fabrication of LNG containment and the ship hull.
Deltamarin managing director Mika Laurilehto said: “As a bulk carrier, the vessel is easier and cheaper to build compared to a traditional gas carrier, and there may be many new potential yards capable of constructing such a vessel.”
The patented containment design has been approved by classification societies, and is available for smaller-scale gas carriers of 31,000m³.
The companies expect to provide medium- and larger-scale vessels with a similar design in future.
In September, Deltamarin and Aker Arctic Technology launched the Aframax-sized tanker concept for crude oil and oil product transports in the arctic.
