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

First Headline

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.

Double Bow Thruster Removal by Subsea Global Solutions

The benefits of removing a damaged bow thruster afloat are many. The customer was able to prevent further damage to the bearings and gears caused by the presence of seawater in the gear housing and the procedures allows the units to be overhauled prior to the vessels next dry-dock—or, they can be re-installed afloat by Subsea Global Solutions, which would help to eliminate the need for additional tug cost.
