Gulfstar FPS™

Alliance Eng. Houston, Texas were awarded the detailed engineering and design of the topside facilities and deck for Williams Partners’ Gulfstar FPS™ spar production platform.

Tungum used on new platform concept for the Gulf of Mexico Tungum tube is well known for its long life (25 years +) in offshore environments and has a very successful history of use in non-process application in the North Sea. The knowledge and confidence in Tungum has over the last 10 years grown to include assets in the Gulf of Mexico. Where instrument tube failures of other materials have occurred due to pitting and crevice corrosion, operators have begun to refit with Tungum tube. This confidence in the material has now extended to a new build on the Williams Partners with Hess and Chevron Gulfstar in the Tubular Bells Field. Engineering design of this platform was carried out by Alliance Eng. Houston, Tx. This is the first of 5 planned for production over the next 10 years.
