This leads to a more efficient execution of the job which in turn saves customer costs.

ROV is absolutely required in inspecting nets in the aquaculture industry.

Polishing propellers and hull cleaning

Polishing the propeller and cleaning the hull gives better fuel economy and is a reasonable alternative to taking the ship in dry dock. We use hydraulically operated washing and polishing equipment. We can mobilize both from land with the diver trailer, which is preferable, or we can come by boat. When polishing the propellers and cleaning hull, the diver carefully surveys the entire surface and reports any deviations and damages found.
