Gosho, 661 Ryoseimaru, and 381 Ryoseimaru, our grab dredger vessels, have completed a dredging work to construct a new container berth called Tuas Terminal Finger 2 and its access channel in the Tuas Terminal Phase 1 project in Singapore. The project was operated by Dredging International Asia and Pacific (DIAP)

At present, 381 Ryoseimaru came back to Japan and is working on domestic projects. Gosho and 661 Ryoseimaru are on maintenance for a new opportunity.
