Hempel launches new fuel-saving fouling defence system

Hempel has launched a new three-coat fouling defence system Hempaguard MaX, which delivers a guaranteed maximum speed loss of 1.2 per cent over five years*.

Hempaguard MaX is applied in three layers, cutting application time and reducing the time vessels need to spend in dry-dock by up to two days. The three-coat system reduces drag and results in significantly lower fuel requirements. The combination of less time in dry-dock and increased fuel savings is expected to result in a payback time of three months, according to Hempel**.

Speaking at the launch in London, today, Hempel’s head of marine group product management, Davide Ippolito, said: “The high level of fuel savings and hull protection are achieved due to the low average hull roughness (AHR) level delivered by the whole coating system, very low speed loss over the entire operational period and improved anticorrosive capabilities.”

“Hempaguard MaX is the next logical step for shipowners and operators seeking to maximise their efficiency and reduce associated CO2 emissions. At a time where marginal gains are of importance and environmental regulations are becoming stricter, the choice of hull coating can make a significant difference.”

The new system builds on the success of its flagship hull coating Hempaguard X7. Since its launch in 2013, this coating has been applied to over 1500 vessels and according to Hempel, has allowed owners to collectively reduce their annual bunker bill by USD 500 million and over 10 million tonnes in CO2 emissions.

Hempaguard MaX is able to exploit the synergies between its three different layers: Hempaprime Immerse 900, tie-coat Nexus II, and Hempaguard X8.

The top coat Hempaguard X8 is built on Hempel’s enhanced patented Actiguard technology. This coating combines the smoothness of a silicone coating with an improved hydrogel microlayer and active ingredient to provide outstanding antifouling performance, full operational flexibility and smooth hull.

Hempaprime Immerse 900 and Nexus II contribute significantly to Hempaguard MaX’s low AHR. A smoother hull delivers less drag and improved fuel efficiency from day one.

Hempaprime Immerse 900 is an anticorrosive primer that can be applied in one coat, while Nexus II is a next generation tie-coat technology with improved anticorrosive capabilities. Together, they provide the same protection delivered by two standard maintenance epoxy coats, reduce time in the dock for faster return to service and ultimately save money for the shipowner and operators.

Hempaguard MaX delivers:

– Powerful advanced fouling defence coating system with increased smoothness

– Low Average Hull Roughness (AHR) driven by the whole coating system – improving fuel efficiency

– 1.2 per cent maximum guaranteed speed loss1 over five years

– Enhanced anti-corrosive capabilities

– Three coat system that saves up to two days in dock – saving time and money.

– Improved idle time antifouling guarantee of 120 days

*Speed loss: If a vessel’s main engine is set at a certain power output, it will propel the ship through the water at a certain speed. Over time, fouling accumulation will increase drag and cause the speed of the ship to reduce even if the main engine power output remains constant. This reduction in speed is termed “speed loss”.

**Based on a VLCC with activity level of 70 per cent and burning low sulphur fuel costing 35 per cent more than standard bunker fuel over a five-year life cycle. Hempaguard MaX system delivers an annual saving of around USD 1.8 million compared to a market average antifouling. This equates to a ROI (return on investment) of three months.
