The partly Norwegian state-owned oil and gas company Equinor, formerly known as Statoil, has signed a hull cleaning frame agreement for its fleet of oil and gas tankers operating in Scandinavia, Asia, the Middle East and Europe with HullWiper.
HullWiper is an award-winning remotely operated vehicle (ROV) system that uses adjustable seawater jets under variable pressure to remove hull fouling, instead of brushes or abrasives, minimising the risk of damage to expensive anti-fouling coatings.
According to HullWiper, no divers are needed in the hull cleaning process, reducing the risk to human life and the ROV-based cleaning can be conducted day or night, in most weather conditions and while cargo operations are underway.
The HullWiper ROV's removed residues are collected by an onboard filter and deposited into dedicated drums onshore for locally approved environmental disposal.
The filter is said to reduce the risk of cross-pollination of waters with alien species.
HullWiper managing director Simon Doran said “We help shipowners and operators to act proactively to comply with ever-more stringent rules and regulations governing the entry of vessels into ports and operations offshore.”
HullWiper now operates from ports in Sweden, Singapore, Spain, Denmark, Norway, Egypt, Australia, Gibraltar and the UAE, as well as other key locations in the Middle East on an ad hoc basis.
New HullWiper operations in Panama and Mauritius are coming in Q2 2019, with advanced discussions ongoing for other locations.
