Project Highlights
Project Management - A $200M project involving designers, engineers and fabricators around the world to produce a high-tech SPAR for operation in 5,600 feet of water. The SPAR was designed by SparTEC Inc. of USA with the main structure built in the remote island of Batam, Indonesia, and the top-side built in the USA.

The project takes advantage of open database technology to link engineering data in ShipConstructor’s SQL server database with corporate ERP systems including the Primavera P3e project management system. This turnkey engineer-procure-construct-install project demonstrates the powerful ERP database integration capabilities to enable complex rig construction in remote low-cost facilities.

Virtual Reality Fly-Throughs - The SPAR is one of the world's deepest dry tree platforms and demands extremely high fabrication quality control as it is impossible to dry-dock the structure once it is ‘launched’ into the sea. At its Batam Island fabrication yard in Indonesia, J. Ray McDermott designers and engineers make extensive use of Virtual Reality fly-through meetings with class society, production and Owner to ensure smooth project planning and design approval cycles. Virtual Reality techniques also helped to speed up training of the steel fabricators in Batam who were handling complex SPAR building for the first time.

Short Learning Curve - A small team of Indonesian engineers spent 10 days training to use ShipConstructor for the structural 3D modeling, production drawings, nesting, and NC-cutting. The detailed production drawings of the complete SPAR lower structure of some 12,900 tonnes of structural steel were completed in less than eight months by six engineers – a testament to the user-friendliness of ShipConstructor’s software suite!
