After five years development: Researchers at Hempel know that their development save fuels.

Global coatings supplier Hempel launched "Hempaguard", a new hull coating concept for the shipping industry which offers both: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.

Silicon-hydrogel activated with surface retention of the biocide

With rising bunkering costs, tightening environmental regulations and mandatory Ship Energy Efficiency Management Plans (SEEMP), fleet operators turned to the inventor for a new hull coating that really could
make a much-needed difference to their business.
As a result, scientists spent five years developing and testing the patented 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.
The result is a unique fouling defence system during long idle periods, plus remarkable fuel savings and flexibility.

Increased flexibility

The coating is extremely flexible - a product covering most combinations of sailing routes and trading patterns.
"Our tests have shown that it 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,” Claes Skat-Rørdam says.

Satisfaction guarantee contract inclusive

The company is so convinced of the performance that it is offering a performance satisfaction guarantee contract for vessels complying with a full specification.
Launching the product in London to global fleet owners and operators during London International Shipping Week, Fouling Control Marketing Manager Claes Skat-Rørdam said:
"If you are not satisfied for any reason using Hempel’s top tier product , Hempel will pay, under the performance satisfaction guarantee contract, for the conversion back to conventional antifouling and with no questions asked.”
