ClassNK has issued an Approval in Principle (AiP) for the designs of a liquefied CO2 carrier intended to Socket SPAR Unit for injection facility. The certification demonstrates its feasibility from regulatory and safety perspectives.
As CCS projects continue to advance worldwide, Japan faces unique challenges due to its deep and steep offshore waters, where subsea pipeline-based CO2 storage is not always feasible.
Under the Ministry of the Environment’s “Environmentally Friendly CCS Demonstration Project,” a floating offshore injection facility—the “Socket SPAR”—is being considered for installation above storage sites to enable CO2 injection from transport vessels even in such deep-water environments. In 2023, ClassNK issued AiP for the Socket SPAR.
At this time, for the liquefied CO2 carrier designed to accommodate the Socket SPAR, which has been under research and development by Shin Kurushima Sanoyas Shipbuilding Co., Ltd. under a commission from Uyeno Transtech Ltd., a member of the project consortium, ClassNK reviewed the design concept of the vessel based on
