TECHNOLOGY company Wärtsilä Gas Solutions has developed a cargo tank design suitable for LCO2 applications, which was recently awarded Approval in Principle by the classification society DNV

Since new LCO2 carriers are an emerging concept they require detailed attention at the conceptual level.

The total cargo capacity of the Wärtsilä vessel is 7500 cbm, divided into two containment tanks, each of 3750 cbm. Wärtsilä has carried out an intensive engineering analysis to formulate an optimum design for the vessels’ containment system and cargo handling systems, bearing in mind the specific nature of LCO2.

Pål Steinnes GM sales, Wärtsilä Gas Solutions, said, “Liquid CO2 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.

“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.”

Monika Johannesen, head of department, Gas Carrier Excellence Center at DNV, said, “We have been pleased to work with Wärtsilä Gas Solutions on this reliable design concept.

“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.”
