Wärtsilä has conducted a study on the systems and solutions required for Liquid CO2 Carrier (LCO2) vessels, resulting in Wärtsilä Gas Solutions developing a cargo tank design suitable for LCO2 applications, which has been awarded Approval in Principle (AiP) by the classification society DNV.

Since new LCO2 Carriers are an emerging concept and requires detailed attention during conceptual level, Wärtsilä says its experience in gas cargo and handling systems proved invaluable to the results.

The total cargo capacity of the vessels is 7500m3, divided into two containment tanks, each of 3750m3. The company 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.”

“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” said Monika Johannesen, Head of Department, Gas Carrier Excellence Center, DNV.

Capturing and storing CO2 is an important strategy in efforts to reduce global CO2 emissions. According to the Intergovernmental Panel on Climate Change (IPCC), global greenhouse gas (GHG) emissions must be reduced by 50% to 80% by 2050 to avoid dramatic consequences of global warming.

Wärtsilä Gas Solutions offers systems and lifecycle solutions for the gas value chain, the main focus being handling of gas in seaborne transport (storage, fuel, transfer and BOG management), gas to power, liquefaction and biogas solutions.
