Linear Cable Engines

Cable Tensioner Types

OceanSi can manufacture offshore cable tensioners in a wide range of pulling capacities, including 2 ton cable tensioner, 5 ton cable tensioner, 10 ton cable tensioner, 15 ton cable tensioner, 20 ton cable tensioner, 25 ton cable tensioner, 30 ton cable tensioner, 50 ton cable tensioner and 65 ton cable tensioner configurations.

​

Each cable tensioner can be designed around the cable diameter, cable weight, minimum bending radius, cable jacket, required pulling force, track length, pad material, clamping method, operating speed, control system and vessel deck layout.

​

Twin-Track Cable Tensioners

Twin-track cable tensioners, also called dual-track cable tensioners, are commonly used for vertical and horizontal cable lay systems. A twin-track arrangement can use one fixed track and one moving track to grip and control the cable during installation, repair, recovery and deck handling operations.

OceanSi can design twin-track cable tensioners around the required cable diameter, clamping force, track length, pad type, line pull and operating speed. Larger twin-track cable tensioner systems can be configured for cables and flexible products up to large project-specific diameters, depending on the required design and cable data.

​

Triple-Track Cable Tensioners

Triple-track cable tensioners can be used for specialized heavy-duty cable handling applications where additional grip, load balance and tractive force control are required.

A triple-track arrangement can help distribute cable contact more evenly than a single-track system while providing more gripping control than a basic dual-track arrangement. These systems are generally project-specific and can be designed for subsea cable, power cable, umbilical and flexible product handling where the cable load, diameter or operating method requires a tailored tensioner design.

​

Quad-Track Cable Tensioners

Quad-track cable tensioners, also called 4-track cable tensioners, are used for higher gripping capacity and improved load distribution during heavy offshore cable operations.

A quad-track arrangement can provide four gripping surfaces around the cable or flexible product, helping distribute clamping force while supporting high pulling force cable lay, recovery and pull-in operations. OceanSi can manufacture project-specific quad-track cable tensioner systems for heavy subsea cable handling, including 50 ton cable tensioner and 65 ton cable tensioner configurations where required by the project.

​

Tracked and Caterpillar Cable Tensioners

Tracked cable tensioner and caterpillar cable tensioner systems are used where the cable must be gripped, supported and moved through the equipment with stable traction.

The tracks can be tensioned to suit the cable diameter, cable jacket and required clamping force. This helps maintain cable control while reducing the risk of uncontrolled movement during offshore cable lay, recovery and deck handling operations.

​

Hydraulic, Electric & Hybrid Cable Tensioners

OceanSi can manufacture hydraulic cable tensioners, electric cable tensioners and hybrid hydraulic-electric cable tensioner systems depending on the project requirement, available power, deck layout and operating method.

​

Hydraulic cable tensioner systems are suitable for heavy-duty offshore cable handling where pulling force, smooth speed control and reliable tension control are important. These systems can be supplied with hydraulic power units, hydraulic manifolds, proportional control valves, operator panels, emergency stop circuits, guards, deck frames and access platforms.

​

Electric cable tensioners can be designed with electric drive motors, gearboxes, variable frequency drives and PLC-based control systems for projects where electric power, accurate speed control, reduced hydraulic complexity or containerized deck integration is preferred.

​

Hybrid hydraulic-electric cable tensioner systems can combine electric drive motors with hydraulic clamping, hydraulic track adjustment, hydraulic lift systems or hydraulic auxiliary functions. This approach can support efficient cable movement while still providing strong gripping force, controlled track pressure and reliable offshore cable handling performance.

​

OceanSi can configure the drive and control package around line pull, cable diameter, cable clamping force, operating speed, power availability, real time monitoring requirements and the wider cable lay spread.

​

Cable Tensioner Capacity Options

OceanSi can manufacture project-specific cable tensioners for different offshore applications, including:

• 2 ton cable tensioner for light cable handling, small subsea cables and compact deck operations

• 5 ton cable tensioner for fiber optic cable, small power cable and umbilical handling

• 10 ton cable tensioner for offshore cable installation, repair and recovery spreads

• 15 ton cable tensioner for subsea cable lay, power cable handling and deck-mounted cable systems

• 20 ton cable tensioner for heavier offshore cable handling and controlled recovery operations

• 25 ton cable tensioner for project-specific subsea cable installation and pull-in requirements

• 30 ton cable tensioner for high pulling force offshore cable lay and recovery operations

• 50 ton cable tensioner for heavy subsea cable handling, pull-in and offshore recovery projects

• 65 ton cable tensioner for large-diameter cable, umbilical and flexible product handling where high gripping capacity is required

​​

Each system can be supplied as a deck mounted cable tensioner, skid mounted cable tensioner, containerized cable tensioner or integrated into a complete cable lay spread with reels, spoolers, tracks, quadrants, chutes, rollers, hydraulic power units and control systems.
