Long, economical service life
The H - 4 line of connectors has reliable, simple operating characteristics; excellent bending and tensile load capabilities; and a long, economical service life.
Design Philosophy
The H - 4 connector is a hydraulically operated subsea connector. It connects onto a subsea wellhead profile by dog segments engaged by a cam ring. The connector ensures positive engagement and release using a primary and secondary system. Combined use of the systems produces a releasing force 125% greater than the locking force.
Applications
- BOP stack to wellhead
- LMRP to BOP stack
- Completion tree to wellhead
- TLP/subsea template tieback
- Production riser assembly to subsea manifold
- Single point mooring to anchor base
- Caisson completions and artificial island drilling
- Specially adapted applications
Product Characteristics & Benefits
- Optional upper body configurations
- Easy primary seal replacement
- Seal is ROV replaceable and retrievable
- Visual position indicator rod
- Pressure-tight self-energizing seal
- Primary and secondary hydraulic circuits
- Positive mechanical release
