Link latch is our economy subsea connector which is constructed almost entirely from fabricated plate materials.

Operational benefits include automatic azimuth alignment and latch, with manual lock and unlock with clear visual indication.

It is ideal for low tensile load, high shear load, and relatively static applications, or manufacture by a fabrication yard locally / in-country.

Link latch can be integrated directly to a hull, gravity base or pile structure; and as with any of SRP’s subsea connectors, we can integrate sensors, acoustic remote controls and complete automation.
