Project Highlights
Easy to Learn, Easy to Use – Sembawang undertook the turret as a fast-track ShipConstructor pilot project. With only one week of user training, the project team was able to model the complex turret in less than two weeks. With each subsequent design iteration, the team was able to create a completely new 3D model of the turret in about one week.

Plate Expansion and Interference Checking – The turret design consisted of many curved, thick steel plates requiring expansion and forming templates from ShipConstructor. These plates were also penetrated by riser tubes leading from the FPSO to the deep sea oil field, so full 3D modeling of the complete turret structure was imperative to ensure accurate plate cutting, plate forming, and structure and pipe interference checking.

Production Drawings and CNC Integration – Once the design was complete, nesting and assembly drawings and NC code were automatically output from ShipConstructor. The project coincided with the commissioning of a new CNC machine at Sembawang, and ShipConstructor interfaced smoothly with it on the very first trial cut.
