GAC EnvironHull Unveils Fuel Savings Calculator

Ship owners and operators can now compare fuel cost savings reaped by hull cleaning with GAC EnvironHull’s online fuel savings calculator.

A foul-free hull offers the benefits of significantly enhanced fuel efficiency and lower operating costs by reducing resistance in the water. A clean ship sails smoother through the water, gives a greener and more sustainable solution and offers energy savings of up to 10% of fuel.

GAC EnvironHull’s online calculator was developed over the past year in response to market calls for a quick, easy-to-use method of comparing savings achieved through different hull-cleaning techniques at a time when owners and operators are under intense pressure to cut costs. It factors in vessel size, speed, voyage, fuel type, temperature and anti-fouling coating used for a range of vessels including bulk carriers, container ships, LNG/LPG vessels and tankers. It also takes into consideration the hidden costs of divers using brushes or others abrasives, which can damage expensive coatings, when comparing fuel saving achieved through traditional cleaning methods and the HullWiper Remotely Operated Vehicle (ROV).

The system does not require divers, just an operator alongside, and uses pressurised sea water jets to dislodge and remove fouling without damaging the paint beneath. Using GAC EnvironHull’s environmentally-friendly system also saves up to 30% on costs related to antifouling coatings. Taking all the operational costs into consideration, using HullWiper can help reap savings of 50-100% for shipping companies.

The calculator – at http://gacc.environhull.com – can accessed and used by PC, laptop, tablet and smart phone.

HullWiper inventor and GAC EnvironHull’s Technical Director Robert Anderson says: “This new tool gives users an easy way to plan their route, calculate and compare savings. With it, they can make an informed decision about which hull cleaning system to use to optimise their vessel’s performance and profit.”
