DNV has issued an approval in principle (AiP) for a new cargo tank design from Wärtsilä Gas Solutions for liquid CO2 (LCO2) carriers
Maritime gas transport technology provider Wärtsilä said the new cargo tank design is for vessels with a total capacity of 7,500 m3, divided into two containment tanks, each of 3,750 m3. Wärtsilä reported it 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.
“Liquid CO2 is increasingly relevant in global efforts to reduce greenhouse gas emissions and promote a greener future,” said Wärtsilä Gas Solutions general manager sales Pål Steinnes. “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,” said Mr Steinnes.
“The review process has been extensive, and we trust their solution will contribute to facilitating the trade in liquid CO2 as a factor in reducing emissions,” said DNV gas carrier segment excellence centre department head Monika Johannessen.
Carbon capture, storage and utilisation can play an important role in efforts to reduce global CO2 emissions. According to the Intergovernmental Panel on Climate Change, global greenhouse gas emissions must be reduced by 50 to 80% by 2050 to avoid dramatic consequences of global warming.
