Deltamarin and Brevik Technology launch a revolutionary multigas carrier design

Deltamarin Ltd and Brevik Technology AS, a VARD affiliate, have joined forces by developing a novel multigas carrier design, G.Delta, which is expected to change the nature of the gas carrying industry. The concept combines in unprecedented way the successful design of Deltamarin’s B.Delta and the new-generation patented cylindrical gas tanks by Brevik Technology.

By combining the readily available and proven B.Delta design and separate cylindrical gas containment tanks, a cost-efficient and easy-to-build G.Delta solution is now available to the gas carrier market. The design can be utilised for LNG, LPG, LEG and ethane carriers.

“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”, explains Brevik Technology’s Managing Director Øystein Kristoffersen Sæther. Based on Brevik Technology’s extensive research and development a unique independent gas carrying method has been created to challenge the traditional and expensive way of building the vessel and the tanks as one entity. The patented containment design has already been approved by classification societies.

The cylindrical tank design allows the tanks to expand in all directions without putting stress on the vessel hull. The independent containment system, which can be built into a vessel as is, results in better possibilities to utilise the existing well-proven ship design. “This is where the ship owner can get significant benefits by choosing a readily available and highly efficient B.Delta hull design already proven in operation”, says Deltamarin’s Managing Director Mika Laurilehto. The G.Delta design based on the B.Delta is actually a bulk carrier design equipped with cylindrical tanks for the gas cargo. “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”, continues Laurilehto.

A highly competitive economical and easy-to-build product is now available for the market for smaller-scale gas carriers of 31,000 m3. In future, it is planned that medium- and larger-scale vessels will also be provided with a similar design. Along with newbuilds, the G.Delta design will also be available for retrofit vessels such as the conversion of a bulk carrier to gas carrier. “Gas transportation needs are constantly growing along with increasing gas utilisation. We are very proud to boost industry development by offering ship owners a cost-efficient solution and making the construction of gas carriers easier”, say Sæther and Laurilehto.
