HEAVY DUTY ROPE TENSIONER FOR BOP TETHERING
The Linear Rope Tensioner (LRT) is a rope tensioner with capability to continuously pull excess length of wire before application of final pretension.
The tensioner is designed for subsea use in the Wellhead Load Relief (WLR) system.
features and benefits
- Capability to continuously pull excess length of wire, significantly reducing the rig time for BOP tethering
- Provides flexibility in adjusting length of wire required for each tension line which overcomes the need to have several lengths of adjustment wire
- Integrated load monitoring
- Final pretension application using SubseaDesign drive screw system
- Interfaces with standard guide pods for templates, clump weights and suction anchors
2 configurations
LRT with Initial Tension Unit (ITU) ROV operated with hydraulic initial tensioning
LRT with Snatch Block (SB) ROV operated with rig assisted initial tensioning
