Saipem’s unit Moss Maritime has won an approval in principle from classification society DNV for a liquefied hydrogen (LH2) containment system design.
Norway-based Moss Maritime said in a statement that ship transport of LH2 is one of the “key technical challenges in realizing the energy transition to a carbon-free future, and the approval in principle issued by DNV is an important step in validating Moss Maritime’s design.”
Moss Maritime said the inspiration for the LH2 containment system design comes from the well-known Moss LNG spherical containment system, having 50 years of track record in the LNG shipping industry.
The firm has modified and upgraded the Moss LNG tank technology to meet the strict requirements for transport of LH2 at a temperature of -253°C.
Moreover, the Norwegian firm has developed the design in cooperation with the Norwegian research institute SINTEF, as well as having received technical support from DNV and funding from the Research Council of Norway.
Moss Maritime Shell International Trading and Shipping, a unit of Shell, Equinor, and also TotalEnergies EP Norge, a unit of TotalEnergies, have contributed to, and participated in, the design development, it said.
Last year, Moss Maritime also joined forces with Siemens Energy, Fearnley Offshore, and DNV to develop a new LNG carrier.
The partners created the “Ocean Green” concept using the BlueVault energy storage solution that combines a gas turbine and a steam turbine to power the vessel.
