Subsea Plough

The Seabed Cable & Pipeline Burying Plough is designed to bury optical fibres, power cables, umbilicals, and flexible pipelines to depths of up to 5.5 m in water depths of 650 m. Its high-strength chassis, combined with an adjustable high-flow, high-pressure jetting system and seabed skid landing, ensures efficient and reliable burial operations.

Towed by the support vessel, the plough performs simultaneous lay-and-bury operations. Skids are available in multiple sizes and can be fitted with buoyancy modules to match different seabed conditions. A towing-and-lifting integration design allows deployment and recovery with a single vessel crane, simplifying deck operations and reducing handling risks.

Main Features

Transportation & Installation

A highly modular design allows quick assembly and disassembly of the chassis, jetting system, buoyancy units, and main lift point. Supplied with dedicated tools, the system can be packed into standard containers, ensuring efficient transport and reduced mobilisation costs.

Performance Upgrade

Jetting swords are customizable to meet different burial depths and can be quickly changed when required. Skids are available in multiple sizes and can be fitted with buoyancy modules to adapt to complex seabed conditions. Towing and lifting are integrated into a single system, significantly improving operational efficiency.

After-sales Maintenance

We provide 24/7 after-sales support, including product leasing, engineering and operational assistance, repairs, maintenance, and upgrades.

Product Highlights

Leading Cable Detection and Positioning System

Configured with sonars, GPS, USBL, INS, and DVL to provide an integrated solution for navigation and precise cable positioning.

Cutting-edge Towing and Lifting Mode

Towing and lifting functions are fully integrated and switchable by cylinder adjustment. The system adapts to different towing angles autonomously, with real-time feedback on parameters such as angle and towing force.

Advanced High-Pressure Jetting System

Adjustable pressure and flow of the jetting swords, supported by a spare water pump to maintain consistent operational efficiency.
