Mitsubishi Shipbuilding, a Mitsubishi Heavy Industries (MHI) Group company based in Yokohama, Japan, held a keel laying ceremony to mark the start of a new demonstration test ship’s construction.

The new ship is being constructed for the transportation of liquefied carbon dioxide (LCO₂).

The ceremony was held at the Enoura Plant of MHI’s Shimonoseki Shipyard & Machinery Works in Shimonoseki, Yamaguchi Prefecture, in the presence of representatives of Sanyu Kisen, the ship’s owner.

The test ship will be used by Mitsubishi in combination with initiatives by the New Energy and Industrial Technology Development Organisation (NEDO) for demonstration projects.

The ship will be chartered to the Engineering Advancement Association of Japan (ENAA), one of the consignees for the NEDO demonstration projects.

ENAA will commission three additional project partners, namely Kawasaki Kisen Kaisha (“K” Line), Nippon Gas Line and Ochanomizu University, to carry out research and development (R&D) on the pressure control and stability of the LCO₂ transported on the ship.
