CleanSubsea

CleanSubsea operates as an Australian maritime technology firm specializing in biofouling management and in-water hull cleaning solutions. Headquartered in Henderson, Western Australia, the organization was established to address the dual challenges of maintaining vessel efficiency and protecting marine ecosystems. As global shipping regulations have increasingly targeted the transport of invasive marine species and the release of toxic anti-fouling paint residues, CleanSubsea focused its engineering efforts on developing systems capable of cleaning ships while simultaneously containing the resulting debris. The company’s emergence in the maritime sector responded to a significant gap in port services. Historically, many ports prohibited in-water cleaning due to the pollution risks associated with traditional scrubbing, which releases heavy metals and biological material into the water column. CleanSubsea developed a proprietary approach centered on a fully contained capture and filtration process. This technology allows the company to remove marine growth from hulls without damaging the underlying anti-fouling coating or contaminating local waters. By vacuuming and treating effluent at the source, they ensure that solid waste is separated and disposed of onshore rather than being dispersed into the harbor. This operational capability serves a diverse spectrum of the maritime industry, ranging from commercial bulk carriers and container ships to naval defense fleets and offshore energy infrastructure. CleanSubsea plays a vital role in vessel maintenance strategies, as clean hulls significantly reduce drag, leading to lower fuel consumption and reduced greenhouse gas emissions. Consequently, the firm supports the industry’s broader decarbonization goals while facilitating compliance with strict biosecurity protocols. Their presence in Western Australia, a region known for stringent environmental protections, has allowed them to validate their methods against some of the world's most rigorous standards. Through its specialized services, CleanSubsea enables port authorities to safely reopen their waters to maintenance activities, bridging the divide between operational logistics and environmental stewardship in the global shipping trade.
