Subsea connector specialist, First Subsea Ltd, has announced the integration of Hyperlast 101 Twin Sealing system with its range of pipeline recovery tools (PRT) used to recover subsea flowline and gas export production pipelines to the surface. The twin polyurethane seals increase the PRT’s resilience and scope for long-term deployment in deepwater and ultra-deepwater.
The twin seal system follows an 18 month research and development programme with a leading subsea plug OEM. Key features of the sealing system include the primary and secondary composite Hyperlast 101 seals in combination with an internal check valve for shallow and deepwater applications. The tool’s patented Ballgrab pipe grip mechanism is suitable for loads in excess of 1,200mT.
