The Envirocart™: An Award-Winning
In-Water Hull Cleaning Solution

This innovative technology tested and supported by the required regulatory certifications in hand, removes the very costly and time-consuming exercise of dry-docking commercial vessels for hull cleaning. This in turn enables a viable, regular, in-water cleaning maintenance protocol that significantly reduces fuel consumption and carbon emissions, in the maritime sector.

Envirocart™ In-Water Hull Cleaning activity has received Operational Planning Approval from the Fremantle Port Authority and is registered with the Department of Water and Environmental Regulation, while the company also works closely with the Department of Fisheries.

CleanSubSea’s Envirocart™ has completed a number of commercial cleans, through its Licensed Operator and is working through its final optimisation process as it prepares to manufacture further units to establish operations in other locations. The Envirocart™ is set to revolutionise the international hull cleaning industry as we know it today.

With our specialised and fully in-house developed technology, our Licenced Operator can provide environmentally friendly underwater hull cleaning, inspection and propeller polishing services—compliant with the International Maritime Organization (IMO) and Marine Environment Protection Committee’s (MEPC) Guidelines—for biofouling control and management.

Increasing regulations from IMO, port authorities and government environmental agencies require proper documentation and retention of vessels’ biofouling management where non-compliance may come with hefty fines for the owner. We, therefore, assist the vessel with their biofouling management record book and provide certification for inspection findings and remedial actions which comply with regulations and ensure compliance during port state control inspections.
