DWHC
Deepwater, high-capacity collet connector
Stand up to the high loads encountered in ultradeepwater applications.
HC
High-capacity collet connector
The HC high-capacity collet connector is similar to the popular Model 70 connector but is designed to provide greater clamping force to withstand higher separating forces. Similar to the Model 70, it locks to mating hub via pivoted locking segments, or fingers, which form a funnel to guide the connector into position. It has a large actuating piston area that creates greater preload at a given hydraulic pressure than the Model 70, as well as higher locking and unlocking forces.
The HC connector has a short swallow (shorter than any major wellhead connector on the market), tapered hub profile, and positive unlocking system that allow disconnection at angles up to 30°.
