WYANDOTTE, Michigan -- BASF has collaborated with Perma-Pipe Oil and Gas, under a contract for The Bayou Companies, to supply glass syntactic polyurethane (GSPU) insulation for the Peridido development in the Gulf of Mexico.

Perma-Pipe applied its Auto-Therm GSPU "wet" insulation to fusion bonded epoxy (FBE) coated pipe for the project, which boasts the deepest subsea insulated flowline installed in the world to date, according to the companies.

Installed in a water depth of 9,627 ft (2,934 m), BASF Elastoshore polyurethane technology was employed as part of the GSPU wet insulation to more than 15 mi (24 km) of insulated flowline pipe. Elastoshore polyurethane systems use a proprietary technology that results in a finished product with temperature and hydrolysis resistance with very low water absorption, the companies say.
