Modularity: A modular system that is road transportable for economical road/sea transport.
Easily mobilised: Assembled on the quayside and lifted on board in one lift for the HLS, and second lift for the tensioner.
User friendly: The main HLS structure combines a tensioner frame, overboarding chute and moving work table. The system also has a low tension chute and integrated runway beams & davits for buoyancy installation/removal. Pad basket storage located beside the tensioner to provide access for safe and efficient tensioner pad change out when offshore
Accessible: All operational areas of the HLS are accessible by ladders and platforms, complete with handrails. Sufficient lighting throughout to facilitate 24-hour operations with an integrated power supply.
Versatility: Designed to integrate with MDL range of tensioners up to 50Te line pull.
Project Focused: The HLS structure and work table system have integrated 10Te SWL swivel hoist rings to aid product handing operations.
Safe: E-stops are mounted at each end of the HLS base frame allowing for safe control of operations.
Optional Extras: As each project has different requirements, the following optional extras can be supplied with the HLS:
4.2m radius overboarding chute insert.
2x2Te SWL hydraulic davit arms, complete with 180 degree pivot to aid jewellery handing.
Samson Post with sheaves for direction change for lowering and recovering ends via an A&R winch system.
Integrated pull-through 10Te SWL winch.
Dedicated 3.75m radius deck deflector with firing line adjustment of 3.2m via hydraulic cylinder system.
