Subsea now offers a Ship Hull Cleaning ROV for those situations where cleaning with other methods is not possible

Our new ROV vessel hull cleaning system works great with:

  • Deep depths with no time restrictions
  • Locations where “manned” diving is restricted
  • In environmentally sensitive areas where spoils collection is essential

Cleaning with our ROV can be fully filtered with a 3-stage filtering process reducing the effluent to less than 1 micron with clean water returned to the sea. It can also be deployed offshore with no filtering.
