DSTI subsea swivels allow relative rotation between flowline equipment and flowline pipe to maintain proper angular positioning during installation, therefore reducing installation time and eliminating bending moments to prevent equipment / pipe damage as subsea equipment is lowered to the sea floor. To date, we've manufactured, tested, qualified, and delivered nearly 200 subsea swivels - reliably installed and operating in field locations worldwide. Committed to the ever-changing challenges of offshore oil and gas development, we've made significant and ongoing investments including capacity manufacturing and custom pressure and load test equipment for testing products up to 55” [1400 mm] in diameter, bending loads up to 3 million ft-lbs [4100 kNm] and tensional loads up to 3.1 million lbf [13900 kN].
