Subsea Tractor “Taurus”

Tractor "Taurus" features a highly modular and open-frame design, enabling flexible integration of subsystems for diverse trenching missions. Its combined track and skid system ensures stability across varying seabed terrains, while customizable buoyancy options support enhanced stability and future upgrades. The tractor is compatible with multiple excavation methods, including jetting, chain cutting, and wheel cutting. Powered by intelligent operation assistance, the system integrates machine learning–driven cable tracking, subsea positioning, and real-time attitude adjustment. Advanced capabilities such as autonomous tracking, multi-level cable tension monitoring, and topology-based fault diagnostics further enhance precision, safety, and operational efficiency in subsea trenching tasks.

Functional Features

Product Highlights

Advanced Cable Protection System

In the burying operation, the track system works with floating jetting system, cable survey devices, and load sensors to achieve fast cable burying while avoid any damage to target cables or other surrounding infrastructures.

Cutting-edge Cable Tracking System

Support powerful cable tracking system and acoustic imaging devices, such as Teledyne and Optimal Ranging, for cable direction and position measurement under high sea state.

Progressive Positioning & Navigation System

GPS and USBL positioning system, INS, DVL, and various combinations of navigation software and hardware are configured for real-time positioning and combination monitoring of the position and direction of the tractor, surface support vessel, and cable at different depths.

Advanced High-pressure Jetting System

The spacing between left and right jetting sword can be adjusted independently to achieve different trenching width. Each water circuit can be on-off independently, adaptive to different seabed soil conditions and burial depth.Optional independent depressor or integrated depressor to cope with different target cable types.Optional front jetting system to further improve trenching efficiency.
