Motion-compensated rail quadrant systems for second-end deployment of submarine cable. Two delivered packages: 15 MT with 4 m MBR and 20 MT with 5 m MBR.
Both builds deploy the second end of offshore wind export and inter-array cables with active motion compensation, extending the weather window and vessel uptime. Choose by lifting capacity, cable bend radius and how much of the handling package you need.
Rail quadrant with integrated overboarding chute for the GL 2030 DP2 barge.
Full quadrant handling package with A-frame, winches, tracks and monitoring. ABS class.

Every quadrant package arrives at the shipyard class-approved, load-tested and supported by the Dimension commissioning and operations crew.
Quadrant and chute track vessel heave and pitch in real time, reducing dynamic loads on the cable.
Track quadrant with polyurethane-coated rollers holds the cable to its minimum bend radius.
Overboarding chutes with low-friction contact surfaces protect the cable at the stern.
Operates in step with the tensioner and the vessel's cable-lay control system.
Structure checked for dynamic and impact load cases, with amplification factors on SWL and design loads.
Fail-safe locking, emergency stop, marine-grade corrosion protection and a robust deck interface.
The 20 MT / 5 m MBR quadrant was delivered as a complete handling package within the SFE Adventurer cable-lay spread: launch & recovery A-frame, overboarding motion compensation, rail quadrant, stern chutes, winches, tracks, cable highway and monitoring. Engineered and fabricated in Singapore.
A sister 15 MT / 4 m MBR rail quadrant and overboarding chute spread was delivered for the GL 2030 DP2 Cable Lay Barge (LS Marine Solution).
From feasibility through commissioning — Dimension delivers in-house engineered marine equipment, backed by 14+ years of offshore operations.
