Hull Cleaning keeps your ship profitable

Our Hull Cleaning ROVs have been developed to remain operational even during harsh sea conditions and strong tide. A powerful propulsion system enables the ROVs to defeat extreme forces that are exerted on the Hull Cleaning unit.

In many cases, we can eliminate workboat charter costs, as we have completed various Hull Cleaning services from the deck of our client’s vessel itself. Bulk carriers, in particular, are very suitable for this approach. During ship to ship ops or other cargo operations, our teams will remain productive. Usually, without any delays or downtime. Our Hull Cleaning and inspection ROVs are launchable from a containerized or portable control station.
