No other part of a ship receives the same kind of battering as a
With that in mind, Hempel set about creating a coating that
was tough enough to cope with both the unique abrasive and
impact stresses imposed by dry cargoes, and the intense stresses
placed on other exposed areas of the ship. The result is Hempadur
Ultra-Strength 47500, a powerhouse of a coating that delivers
superior asset protection.
Hempadur Ultra-Strength is a new epoxy coating for ship cargo
holds with an industry-leading repair interval. Officially released in
July, the durable coating provides excellent abrasion and impact
resistance -- making it ideal for protecting ship cargo holds from
rough treatment, according to Hempel.
Hempadur Ultra-Strength 47500 protects ship cargo holds from
both mechanical damage and the severe abrasion caused when
loading hard cargoes. With a ten-year repair interval, the best on
the market, it enables shipowners to extend periods between
repairs -- and so helps bring down maintenance costs.
Michael Aamodt, Group Marine Product Manager at Hempel,
commented: "The cargo hold is exposed to more battering and
rough treatment than any other part of a ship, so shipowners need
an extremely tough cargo hold coating. Hempadur Ultra-Strength
offers better protection than any other epoxy coating. This means
it lasts longer and shipowners can save time and money as they
have to do less repairs or recoating."
Scientific & Technical Services Limited in the UK has performed
independent coal cargo testing on Hempadur Ultra-Strength and
ranks it as the best performing epoxy coating against warm, hard
According to Hempel, Hempadur Ultra-Strength is also best in
class in application performance. It dries quicker than similar
coatings on the market, and can be applied all year round in
most weather conditions. With a high glass transition
temperature, the coating will remain hard even when exposed to
very warm coal cargoes.

Being able to efficiently control the speed of a vessel's cooling
pumps according to the temperature of the sea significantly
reduces energy consumption and costs below deck.
Grundfos' speed-controlled cooling solutions for marine
applications offer savings of up to 50 percent, according to
Looking to reduce energy consumption at sea? A control
solution from Grundfos is the obvious choice. The advanced
technology automatically adjusts the speed of the cooling pumps
according to the actual temperature of the seawater. This means
that no energy is wasted cooling the engine at maximum speed
when there is in fact no need for it.
Break with tradition
Cooling solutions are designed to cool at a constant seawater
temperature of 32°C -- regardless of whether the vessel is sailing
around the Persian Gulf or the Baltic Sea in January. Grundfos now
breaks with this, offering a variable-speed alternative that is as
beneficial to the environment as it is to the ship owner's economy.
Reduced energy consumption equals reduced CO2 emissions and
fuel costs -- an increasingly important factor in every industry and
one that Grundfos takes very seriously.
The advanced Grundfos solution efficiently controls the speed
of virtually any Grundfos pump, new or old, irrespective of size
and power range. The series is suitable for a variety of marine
applications including: Seawater cooling pumps; freshwater cooling
pumps; boiler feeds; utilities (HVAC, water supply, etcetera).
The versatility of the advanced solution makes way for
enormous energy savings on a vessel. In addition, the solution
keeps everything under automatic control.
Know-how leads the way
Speed control by means of frequency converters has been part
of Grundfos' portfolio for 25 years. Industries all over the world
benefit from the extensive know-how built into every Grundfos
solution, ensuring that energy consumption is kept at bay. The
advanced controls are part of Grundfos' comprehensive E-solution
programme of speed-controlled pump systems, developed to make
way for more energy-efficient operations. And since around 70
percent of the total costs incurred over a variable-speed pump's life
are attributed to energy consumption, there is good reason.
Please feel free to meet with Grundfos at the KORMARINE
Exhibition in South Korea, October 21-24, 2009.
