PAINT and COATING developments
Hempasil X3 is an innovative new coating for ships' hulls that
can save shipowners thousands of dollars in fuel bills and
drastically cut the amount of CO2 released into the environment,
according to Hempel -- and it has now won a prestigious award
for outstanding product development and innovation.
Hempasil X3, the new antifouling coating developed by Denmark-
based Hempel, has won Ingeniørens Product Award 2009. The prize is
given by Ingeniøren, a magazine published by the Danish Society of
Engineers, to new Danish products that demonstrate a clear market
focus with outstanding technological innovation.
"We are extremely proud of this award," says Martin Wiese,
Hempel's Group Vice President R&D. "It's the result of a clear
development strategy that encourages direct collaboration between
our Marketing and R and D departments to ensure that our R and
D focuses directly on customer needs. More and more customers
demand products that lower operating costs and help reduce the
impact of their activities on the environment. Hempasil X3 does
both these things. Our creative product engineers have taken an
exciting idea and created a product with incredible economic and
Hempasil X3 is Hempel's third-generation fouling release
coating system and uses pioneering hydrogel technology to stop
fouling organisms (from biological slime and seaweed to barnacles)
from attaching to a ship's hull. The hydrogel fools the organisms
into thinking the ship's hull is liquid, essentially rendering the hull
invisible so they don't attach. This keeps the hull smooth and
reduces drag in the water.
As a result, Hempasil X3 can guarantee fuel savings of between
four and eight per cent in the first year of use, depending on the
vessel type. Hempel supplies SeaTrend software as standard with
Hempasil X3 to enable shipowners to measure the fuel-saving
effects for themselves.
Hempasil X3 has the potential to save the world from millions
of tonnes of CO2 each year, because less fuel means an equivalent
reduction in CO2 emissions from vessels. "Imagine Hempasil X3
was applied to the entire world fleet. Potentially, it could save the
world from 90 million tonnes of CO2 a year, the same amount of
CO2 emitted from Greece," says Torben Rasmussen, Group Product
Manager at Hempel.
Based on hydrogel silicone, Hempasil X3 is designed for vessel
speeds down to eight knots and vessels operating at low activity.
The hydrogel is made up of a network of water-insoluble, super-
absorbent polymer chains, and these form a microlayer between
the solid silicone and the seawater. Due to the high water content,
the hydrogel appears as liquid to fouling organisms, making the
