Wyandotte, Michigan -- BASF is helping two deep sub-sea developments sited in the Gulf pf Mexico by supplying mercury-free PU systems for glass/foam insulation for a range of components. The chemicals group is working with Perma-Pipe Oil and Gas, of New Iberia, Louisiana, to supply glass syntactic polyurethane (GSPU) insulation for the Mandy and Who Dat subsea developments.
Permpa Pipe is using BASF's Elastoshore ZeroHg technology for its Auto-Therm GSPU "wet" insulation, applied to the flowlines, risers, pipeline end terminations (PLETS), manifold, jumpers and shrouds required for the subsea developments.
The announcement said Perma-Pipe has insulated more than 81 000 ft, or 16 miles, of 4- and 6- inch flowlines and risers for the subsea developments. BASF's Polyurethane Solutions team worked closely with Perma-Pipe to develop customised Elastoshore products that fit Perma-Pipe processes for both line pipe and custom coating applications.
BASF commented that Perma-Pipe's Auto-Therm GSPU technology, using BASF's materials, is being used in more than 100 miles of flowline and riser pipe insulation currently installed in the Gulf of Mexico, in projects where Perma-Pipe is under contract to LLOG Exploration Co. llc, based in Houston, Texas.
"Our customised polyurethane solutions enable Perma-Pipe to factory insulate pipe and field equipment of various shapes and sizes with minimal adjustments to the process," said Dr Karl Gust, Market Manager, Polyurethane Solutions for BASF in North America. "We recently moved the manufacture of our GSPU product line to our Polyurethane Solutions Systems House in Houston, and believe it is critical to keep our product manufacturing as close to our customers as possible."
Both deep-ocean sites are in the Mississippi Canyon Blocks of the Gulf of Mexico: Who Dat is in Block numbers 503 to 547 at a depth of 3000 ft. The field, which became operational in December 201, required insulation of 51 000 ft of flowline as well as four PLETS, eight jumpers and fifteen shroud covers.
BASFsaid the Mandy field, in Block number 199 at 3000 ft, needed insulation of 31 000 ft of flowlines and risers, four PLETS, six jumpers, nine shroud covers, and one manifold. Installation of the equipment is planned for March 2012, and the field will become operational in April 2012.
"Keeping the same chemistry of wet insulation for the flowlines and subsea equipment is an advantage for our operators," said Hank Reuser, vice president of sales and marketing for Perma-Pipe Oil and Gas, in the announcement. "Using the same materials, Auto-Therm GSPU, for the entire scope of flow assurance promotes consistency, and a strong sense of confidence."
