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

Subtrench Two Trenching Machine: Cables, Flexibles & Umbilicals.

Similarly to the requirements for the pipeline and stiff flexible and umbilical trenching machine - Subtrench One - modern day cable, umbilical & flexible projects also place a much higher demand on the capability, performance, safety, environmental impact and reliability of subsea trenching equipment and associated operating methodologies than in the past.

Cables, flexibles and umbilicals are less robust than pipelines and hence the trenching machine needs to provide additional measures to minimise the risk of damage during trenching operations. With the advent of offshore wind farms, power cable sizes are increasing and require a handling system suitable for the larger minimum bend radius whilst still maintaining relatively low external loads on the cables. The cable, flexible or umbilical is being required to be trenched to depth on a single pass. The trenching depth is increasing for longer distances and in the case of wind farms; the shore crossing is often in densely populated and environmentally sensitive areas. The need to operate in the range from above the water line and very shallow waters inaccessible to most vessels through to deeper waters is also required. The trenching equipment is required to handle a wider range of soil types, often unknown, at greater reliability and faster trenching speeds. There is also the need to be able to perform remedial trenching of cables that have become exposed over time.

To accommodate the changing requirements for cable, flexible and umbilical trenching, Subtrench has built and operated the proprietary Subtrench Two , a modern day cable trenching machine to achieve these objectives.
