HLS-200
The MDL HLS-200 is a portable horizontal lay system for the deployment and recovery of subsea umbilicals, risers and flowlines (SURF).
The system allows for safe and efficient deployment of product from on-deck reel drive systems and carousels.

Additional Information
A modular system that is road transportable for economical road/sea transport.
The main HLS structure combines a tensioner frame, overboarding chute, a moving work platform and centraliser tulip. The system also incorporates an inboard end termination support table or low tension chute and integrated runway beams for buoyancy installation/removal.
All operational areas of the HLS are accessible by ladders and walkways, complete with handrails.
The HLS integrates with MDL range of tensioners up to 60Te line pull.
E-stops are mounted at each end of the HLS base frame allowing for safe control of operations.
For alternative deck layouts, the system can be supplied with a dedicated 3.75m radius deflector, fixed on a frame foundation which can slide on a deck grillage via a hydraulic cylinder system.
A Samson Post can be provided c/w sheaves for direction change for lowering and recovery ends via an A&R winch system. There are further sheaves incorporated into the HLS for this purpose also.
