Siemens Energy, partners develop new LNG carrier design

Siemens Energy, Moss Maritime, Fearnley Offshore, and DNV have developed a new LNG carrier that will be powered by a hybrid combined-cycle power and propulsion plant.

The “Ocean Green” concept had been created using the BlueVault energy storage solution that combines a gas turbine and a steam turbine to power the vessel, DNV said via social media on Friday.

“Studies undertaken by DNV have found that the Ocean Green system will result in an equivalent CO2 reduction of approximately 11-18 percent and reduce the unit freight cost by approximately 9-17 percent compared to today’s LNG carriers and their current market operational profiles,” it said.

According to a video posted on Siemens Energy’s website, the design incorporates its SGT-400 gas turbine in combination with a heat recovery steam generator, steam turbine, and the mentioned energy storage.

Moreover, the new design allows for increased cargo capacity, lower noise and vibration level, and extends the lifecycle of the vessel, Siemens Energy claims.

Martin Cartwright, DNV Maritime’s business director for gas carriers and FSRUs, said in the statement that this “is a crucial step in mapping out the next generation of gas carriers.”

“Maritime transport continues to play an essential role in building up energy security, which is expected to lead to increasing demand for innovative solutions such as the Ocean Green concept,” he said.
