Power

Nameplate data does not always translate to available power for specific operations. When considering the trencher power, calculate the resulting power that is actually available to power the tracks, water jets and ancillary equipment. In surface fed units where the water pressure is actually generated on the surface, the power available for water jetting on the sea floor is inversely proportional to the water depth. In addition to the extra piping losses, you will generally lose 1 bar (15 psi) per 10m (30 feet) of water depth. Attempting to do work too deep will be slow or fruitless.
