Global coatings supplier Hempel has launched HEMPAGUARD, a new hull coating concept for the shipping industry, which Hempel said offers both outstanding resistance to fouling during idle periods and significant fuel savings. The technology, dubbed ActiGuard, has been five years in development and is based on silicone-hydrogel and biocide science. HEMPAGUARD available as two separate products: HEMPAGUAR X5 and HEMPAGUARD X7.
Hempel’s tests show excellent fouling resistance of up to 120 days during idle periods plus fuel savings of six per cent on average with HEMPAGUARD.
Hempel offers a performance satisfaction guarantee contract for vessels complying with a full HEMPAGUARD X7 specification. Group Product Manager Torben Rasmussen explained, “If you are not satisfied for any reason using Hempel’s top tier product HEMPAGUARD X7, Hempel will pay, under the performance satisfaction guarantee contract, for the conversion of HEMPAGUARD back to conventional antifouling and with no questions asked.”
With rising bunkering costs, tightening environmental regulations and mandatory Ship Energy Efficiency Management Plans (SEEMP), fleet operators turned to Hempel for a new hull coating that really could make a much-needed difference to their business.
As a result, Hempel scientists spent five years developing and testing Hempel’s patented ActiGuard technology. ActiGuard integrates silicone-hydrogel and full diffusion control of biocides in a single coating. Surface retention of the biocide activates the hydrogel, which effectively holds fouling organisms at bay, cutting friction to a minimum while utilizing a minimum amount of biocide. It also has the long-term stability and mechanical properties required of a durable solution, Hempel said.
HEMPAGUARD demonstrates flexibility in that it can cover most combinations of sailing routes and trading patterns.
“Our tests have shown that HEMPAGUARD retains its effectiveness when switching between slow and fast steaming anywhere in the world as well as during extended idle periods of up to 120 days. This is particularly interesting for bulk carriers that can be redirected at short notice, as well as larger container vessels and tankers that may wish to increase speed to meet schedules, or slow steam to achieve extra fuel savings,” Rasmussen said.
