Subsea Cables & Pipeline Trenching
Maximising Reliability & Minimising Risk. Safety Underpins Everything We Do!

Undersea Trenching Research & Development

Subtrench has performed extensive R&D in order to provide state of the art trenching equipment and operational methodologies to minimise the risks whilst maximising the reliability and performance in the field. Scale model testing and full size equipment testing has been performed as well as various studies and research.

R&D has covered:

• Jetting performance in various soils including actual field trenching performance;
• Mechanical cutter performance in various soils including actual field trenching performance;
• Trenching tool development and performance with Professor Cees van Rhee of the world renowned Delft University in the Netherlands;
• Development of proprietary trenching tools;
• Performance of tracked vehicles under the water;
• Detailed analysis of all the various types of lowering processes covering ploughing, jetting without transport, jetting with transport, mechanical cutting, mass flow and eduction and their suitability for different soils and the different trenching requirements for pipelines, cables, flexibles and umbilicals;
• Detailed analysis of the various types of equipment to deliver the trenching processes including free flying, ride on the pipe, sled, tracked, plough and mass flow machines and their suitability for different soils and the different trenching requirements for pipelines, cables, flexibles and umbilicals;
• Detailed analysis of a short listed fifteen recommended trenching machine features covering safety through to support vessels through to the environment.
