HullWiper has signed an agreement with Indian Ocean-based underwater hull cleaning specialists Immersub, marking its first step into the African continent.

HullWiper’s Remotely Operated Vehicle (ROV) uses adjustable seawater jets under variable pressure to remove fouling. No brushes or divers are required, minimising the risk of damage to hull coatings and to human life. Removed residues are collected by an on-board filter and deposited into dedicated drums onshore for locally-approved environmental disposal. The filter also reduces the risk of cross-pollination of waters with alien species.

HullWiper extended its leasing programme in 2017 to work with partners around the world to offer shipowners and operators a cost-efficient, brush- and diver-free alternative to traditional hull cleaning methods.

Protected from the open sea by the world’s third-largest coral reef, which surrounds the island, Mauritius is one of 12 countries spearheading the IMO’s GloFouling project, a collaboration between the Global Environment Facility (GEF), the United Nations Development Programme (UNDP) and IMO.

Simon Doran, HullWiper’s managing director, commented: “As home to some of the world’s rarest plants and animals, Mauritius recognises the need to implement measures to stop the growing threat of foreign aquatic species. “In line with the Mauritius Port Authority’s commitment to sustainable and eco-friendly port activities, it was an obvious choice for our first operational base in East Africa.”

Immersub’s CEO Capt. Pierre Yves Rochecouste, added: “For the past three years, Immersub has been searching for new hull cleaning technologies around the globe that would comply with our two main goals: efficiency and being environmentally friendly. We consider HullWiper to be the future of underwater hull cleaning that underpins our values and goals to provide a safe, sustainable and efficient service to the shipping industry.
