OUR ROV FLEET
SMD CMROV TRENCHER

The SMD CMROV is a cable trencher ROV with hydraulic tracks and a powerful jetting tool with 2 m swords for good trenching performance. The SMD trencher ROV has built up an excellent reputation as a powerful submersible which achieves quality burial in adverse conditions.
First and foremost the ROV is designed for trenching. This means that the driving force behind the design is centered around the jet burial tool. SMD’s high flow jetting technology uses twin jet legs with remote width adjustment and positive (independent) depressor which includes integral cable detectors.
