Wärtsilä Gas Solutions has developed a cargo tank design suitable for liquid carbon dioxide (LCO2) applications – and it’s been awarded Approval in Principle (AiP) by the classification society DNV.

Unveiling the concept on Monday (26th April), Wärtsilä said the total cargo capacity of the vessels is 7500 cubic meters (cbm), divided into two containment tanks, each of 3750 cbm.

Intensive engineering analysis was carried out to formulate an optimum design for the vessels’ containment system and cargo handling systems.

“LCO2 is increasingly relevant in global efforts to reduce greenhouse gas emissions and promote a greener future. It represents an important link in the value chain for the entire carbon capture infrastructure,” said Pål Steinnes GM Sales, Wärtsilä Gas Solutions.

“In developing a robust and proven concept, both in the cargo containment and cargo handling requirements for LCO2 Carriers, we have drawn on our unparalleled experience in gas carrier segments. The AiP from DNV is a valuable endorsement of this work.”

“We have been pleased to work with Wärtsilä Gas Solutions on this reliable design concept,” added Monika Johannesen, Head of Department, Gas Carrier Excellence Centre at DNV. 

“The review process has been extensive, and we trust that their solution will contribute to facilitating the trade in liquid CO2 as a factor in reducing emission.”
