Prysmian Submarine Power Cable Burial Tools

With years of experience and ongoing innovation in submarine cable installation, we have established the most extensive range of advanced installation capabilities and burial tools available worldwide. Our expertise in executing submarine cable installations is unparalleled.

Sea Mole

Sea Mole offers advanced trenching capabilities for burying cables at depths of up to 3.0 meters. As a high-powered, class-leading Trenching Remotely Operated Vehicle (ROV), Sea Mole boasts 1200 horsepower and utilizes either high-flow or high-pressure water jetting to optimize trenching based on seabed conditions.

The vehicle can be equipped with a rear eductor or backwash swords to improve cable burial in specific soil types. It is designed to maintain a burial depth of up to 2.5 meters, even in strong soil conditions. Additionally, Sea Mole is fitted with Teledyne Dual Track TSS440 & TSS350 systems, enabling it to provide real-time burial data to ensure that project objectives are met promptly.

Hydroplow

The Hydroplow is a machine designed to lay and bury cables simultaneously. It operates by using pulling forces from the cable-laying vessel and fluidizing seabed materials with high-pressure water from nozzles on the stinger. This allows the Hydroplow to move with controlled towing forces.

Cables are fed from the laying vessel into a funnel on the stinger's top, using a hydraulic, diverless-operated opening system. A safety lock prevents accidental opening and ensures stability during launch and recovery.
