Peter Livanos-controlled EcoLog has won approval in principle for its new design of low-pressure, shallow-draft liquefied CO2 carriers as it prepares to build out a large-scale business in this sector.

Classification society ABS awarded the AiP for the LCO2 carrier, which has been designed to have a low carbon footprint.

EcoLog head of shipping Panos Deligiannis said the company — which is looking at building out LCO2 terminals and a fleet of owned LCO2 carriers — is developing the world’s first large-scale CO2 service platform in the carbon capture utilisation and storage supply chain.

Deligiannis said: “EcoLog has the ambition to build a business that can liquefy, transport and store 50 million tonnes of CO2 annually anywhere in the world.”

ABS said the AiP follows a joint industry project team including shipbuilder Hanwha Ocean, which developed the hull and cargo tank design, and Babcock LGE, which advised on the cargo handling systems and integration.

EcoLog also contributed to the project with its knowledge of cryogenic gas transportation and how LCO2 shipping fits into the wider CCUS supply chain, ABS said.

For the AiP, the team looked at the detailed design development of this new breed of vessel, taking into account LCO2 critical characteristics, including operational requirements with respect to low pressure and shallow draft.

The effect of a wide variety of CO2 compositions on the resilience and commerciality of the containment and cargo handling system versatility was a key consideration in the AIP study, ABS added.

“The design maximises energy integration and minimises greenhouse gas emissions,” ABS said.

EcoLog recently firmed up a wind-assisted LCO2 carrier design, with design company Deltamarin, which the ship designer said was in readiness for tendering at shipyards.

ABS vice president of global sustainability Panos Koutsourakis said: “The safe transportation of CO2 plays a vital role in the carbon value chain, and we are ready to support such projects with guidance to minimise risks to the crew, vessel and the environment.”

Hanwha Ocean head of engineering and technology unit Seung-Han Moon said: “This vessel that received AiP from ABS is a new type of LCO2 carrier capable of transporting large quantities of liquid CO2, which can dramatically improve operating costs.”
