The wellhead connector is a hydraulically operated connector that can be locked to, and unlocked from, a matching profile at the top of the subsea wellhead housing. The wellhead connector carries a metal seal gasket which provides a seal between the wellhead housing and the wellhead connector.
This metal seal gasket is fully energized by the locking force of the wellhead connector.
The NS-T Threaded Connector has the following features:
• Collet finger segments for direct tensile load path
• Single piece housing for increased bending capacity
• Robust piston seals
• Large actuating piston area creates a greater preload and unlocking force
• Three hydraulic circuits (primary lock, primary un-lock, secondary un-lock)
