Shipyard Facilities
& Equipment Overview

What sets the Sumidagawa Shipyard Company apart is its holistic approach. We undertake everything from design to manufacturing, making us a unique one-stop "shop" in the shipbuilding industry.
In the shipbuilding industry, where division of labor (sectionalism) is common, our approach provides a rare opportunity to make it possible
to directly respond to the customer's needs while creating
an environment that promotes a rapid turnaround.

Shipbuilding Process

Specifications consult
Based on the customer's specifications (size, gross tonnage, sailing speed), the quality of the ship, hull form, main engine, etc. are determined.
Design & Procurement
Based on the specifications move to the design of the hull, piping, electricity, etc. Once completed, orders are placed with manufacturers based on the drawings.
Cutting & Processing
The procured steel or aluminum sheets are cut (or pressed) using NC plasma cutting machines to produce the necessary parts.
Assembly
As the components are assembled, they are welded together to create the hull and on deck structures.
Launch
Once the hull is completed and painted the ship is ready for launch. In some cases, a launching or christening ceremony is held.
Rigging
After the launch, outfitting is completed, including the installation of on-board equipment, along with finishing the interior and other finalizing work.
Trial run
To test the performance of a completed ship the vessel is put through its paces on the open water in order to conduct any tests required by governing regulations.
Final Completion
& Delivery
Final adjustments and finishing touches are made to each piece of equipment and the ship is handed over to the owner.
