OTC 2018: New subsea isolation cap prevents corrosion, marine growth
Offshore staff
HOUSTON– Universal Subsea Inc. unveiled the patent-pending Wellhead Defender subsea isolation cap on Monday, April 30, at the Rice Alliance Startup Roundup at OTC.
Sean Thomas, founder and general manager, Universal Subsea Inc., said: “At the seafloor, various types of corrosion and marine growth cause lost time, lost production, and increased risk to the offshore E&P industry. I have witnessed these issues first hand, working for years with a major wellhead supplier and then as a subject matter expert with a supermajor operator. I was determined to come up with a better subsea protector cap.
“Our Wellhead Defender subsea isolation cap is that solution, with numerous innovative features in the body design and the sealing, locking, and injection features, with five US patents pending. Used in conjunction with our Defender Stasis isolation fluids, the Wellhead Defender subsea isolation cap effectively prevents corrosion and marine growth on critical sealing and locking features of subsea wellheads, preserving the subsea wellhead in a stasis condition.”
The company said that it spent more than 2,000 hours analyzing, selecting, testing, and qualifying the one-piece, corrosion-proof, thermoplastic body.
In contrast, metal subsea protector caps can foster corrosion. It added that competing subsea protector caps typically have ineffective body seals, allowing isolation fluid to quickly leak out to the ocean.
