The UTV1100 can operate in variable conditions, as shown in a recent project off the coast of Denmark. The UTV1100 was tasked with jet trenching a cable from the beach to 2.3km offshore where the UTV1100 tackled rip currents, gulleys, and zero metres water depth. Despite these conditions, the UTV1100 successfully buried a cable bundle consisting of a dual DC power cable and telecoms
The UTV1100 is a light, road transportable, compact shallow water cable burial solution, allowing it to be crane-launched from a wide range of platforms such as multicat, barges or larger vessels. Moreover, this shallow-water TROV spread is provided complete with a dedicated water hose reel and dual surface fed water pumps. The entire spread can be mobilised within just three days.
… we would not hesitate to consider utilising the UTV1100 again.

The UTV1100 exceeded expectations on the project.
… the entire route was able to be buried in excess of the required depth of cover with a single pass.

Having recently undertaken several upgrades and improvements, the UTV1100 is uniquely positioned for shallow water cable burial. The UTV1100 benefits from two 550hp surface water pumps which deliver all their power direct to the jetting sword. This gives the TROV an excellent power-to-size ratio and can trench to approximately 3m deep. With in excess of 200m of umbilical and water hose, the system can operate from 0msw to 200msw. Alternately, the UTV1100 can access remote sites 200m from the host vessel.
In a project off the coast of Saudia Arabia, the UTV1100 performed shallow
water cable burial on over 60km of interconnector power cable for a multi-island
infrastructure development project. The Pharos crew achieved successful burial
in challenging seabed conditions.
This project encountered areas of significant environmentally sensitivity. To
overcome this, Pharos designed a unique silt mitigation solution which was
fitted to the UTV1100, ensuring minimal disruption to the surrounding seabed.
