Destec’s Subsea pipe connector or as known in the subsea industry the ‘Destec GSB Subsea Single
Bolt Connector’ is a purpose designed unit for subsea connection operations where a conventional four bolt G-Range pipe connection would be impractical.
The GSB subsea pipe connectors are supplied with a mounting plate which can if required accommodate guidance / pull-in systems for ease of alignment and provision for stab connectors for electrical and hydraulic circuits.
Standard G-Range or D-Range metal to metal Seal Rings can be used, or the customers own sealing arrangement can be employed.
Larger sizes and special designs (Dual Bore / Multi Bore / Concentric Bore) can also be accommodated. For example some GSB Connectors have been supplied with fabricated Spool pieces for mating to flexible risers.
