Project Highlights
Cutting Time & Costs - High speed aluminium alloy boats require multiple stringers laid out along many frames and bulkheads. Using ShipCAM’s LoftSpace and StiffenerCutout features, Sumidagawa Shipyard Co. Ltd. was able to produce a high number of cutouts quickly and precisely.

Compared to manual lofting, the software cut time and cost since the design team was able to apply a singular design to the three boats in the series, as well as independently take care of production lofting in addition to regular designing.

Ease & Accuracy - ShipConstructor’s Structure module was used to easily produce shape stiffeners, face plates and flanges for frame and bulkhead parts, which allowed for the quick and accurate calculation of weight and CG that is essential to the design of high speed patrol boats. The 3D product model also allowed designers to check and recreate complex parts in 2D by viewing them as digital mockups, virtually eliminating mistakes before production.

Project Management - The SQL database enabled designers to individually input detailed information like materials, parts and measurements with ease, while creating individual structural parts. As a result, the management of the project was simplified dramatically, without jeopardizing accuracy.
