MISALIGNMENT CONNECTOR ELIMINATING TIE-IN MOMENT
SeAlign is the first and only ROV operated connector in the market providing misalignment capability. In addition, it combines robustness and a sealing system that is not affected by external loads.
The SeAlign connector can be supplied as diver flanges with swivelling clamp rings and stud bolts, or ROV operated connectors with 3-segmented, single drive screw clamps and complete vertical or horizontal tie-in systems

The main features include:
- Up to +/- 3˚ hub misalignment
- Acts as ball joint – locked at make-up
- Eliminates tie-in bending moment, only axial load required
- Mechanical end stop in hub profile
- Leak tight at all misalignment angles, M2M
- Design pressure and depth rating to suit most applications
