reduces drag and increases vessel efficiency giving average fuel consumption and associated emissions savings of fiver percent annually compared to typical controlled depletion polymer antifoulings. The coating surface also swells on contact with seawater, helping to smooth out imperfections and potentially further reducing drag.

LUBYON technology reacts with seawater via a constant surface active zone releasing only the optimum amount of biocide over the scheme life to control fouling settlement. Critically, this biocide release rate is largely unaffected by seawater temperature meaning Intercept

8000 LPP has total trading flexibility and can operate across global routes and through all seasons.

Unlike typical silyl and metal acrylate antifoulings, Intercept 8000 LPP replicates the linear polishing of the former shipping industry benchmark tributyltin-based coatings, meaning total predictability with the polishing rate remaining constant throughout the in service period.

Designed for the deep sea market at newbuilding and maintenance and repair, the coating has been extensively monitored with in-service performance validated on multiple vessel types including containers, tankers, bulk carriers and LNGs representing over 4 million dwt.

Also available is an economical version of Intercept 8000 LPP, Intercept 7000. Intercept 7000 features all of the attributes of a typical mid-range biocidal antifouling product with the added benefit of linear polishing.

International Paint has launched Intersleek 1100SR, the shipping industry’s first biocide-free, fluoropolymer technology that tackles the market’s age-old “slime challenge.” Slime, a complex, varied and dynamic organism which begins to colonise surfaces as soon as they enter the water, has been proven to have an adverse effect on the efficiency of all vessel types.

Designed for all commercial vessels, even when slow or ultra-slow steaming, new Intersleek 1100SR slime release technology delivers outstanding macro and micro fouling control with good static resistance, even in warm waters. Slime that can build up during static periods is released by the movement of the vessel through water. This has been achieved by the new patented fluoropolymer in Intersleek 1100SR, which has been developed by enhancing the slime-resistant polymer groups used in earlier generations of Intersleek technology, creating new surface chemistry that specifically resists the adhesion of slime.

International Paint has also introduced Interline 9001, a new
bimodal epoxy coating for the cargo tanks of chemical tank-
ers. Interline 9001 is designed to deliver greater efficiency and
flexibility in the operation of chemical tankers, easily switching
from one cargo to the next with minimal downtime. It can carry
all of the cargoes standard epoxy phenolic technology can, plus
a further 25 percent of the large volume cargoes that it cannot
and has over 60 percent fewer cycling restrictions.
In 2013, Hempel launched several new products aimed at
helping customers reduce
operating costs. This in-
cluded HEMPAGUARD,
a fouling defense product
that promises to have the
most significant impact on
vessel fuel consumption –
and associated CO2 emis-
sions – for many years.
“The only prod-
uct of its kind to come
with a Customer
Satisfaction Guarantee,
HEMPAGUARD delivers
average fuel savings of six
per cent a year compared
to conventional antifoul-
ings, even during vessel
idle periods of up to 120
days, and has seen several
drydock applications each week since it was first launched on
the market in September 2013,” Ottosen said.

In 2013, Hempel completed the launch of its high-solids antifouling range with the introduction of GLOBIC 6000 and GLOBIC 9000. “Based on proven NCT technology, these products deliver outstanding antifouling performance and contain less volatile organic compounds than previous formulations. In total, more than 10,000 vessels have been coated with proven NCT technology since it was first launched,” Ottosen explained. “We also launched HEMPADUR IMPACT 47800 a new cargo hold coating for bulk carriers that ensures vessels spend less time in drydock and significantly reduces maintenance costs for owners.

PPG has a number of new products to speak of. The two most notable ones are PPG’s SigmaGlide 1290 foul release technology and Sigma Nexeon Antifoulant range. “SigmaGlide 1290 is the fourth generation of our core fouling release hull coating technology with an impressive 15-year track record,” said Molenda. “The foul release properties against slime, at low steaming speeds, and its long-term performance characteristics are a competitive advantage. Sigma Nexeon’s range of antifouling products provides very low levels of frictional resistance, outstanding fouling protection and amazing color retention. In addition, this technology is a more environmentally friendly option than the industry’s typical offerings, as it is a copper free antifouling technology. Both the SigmaGlide and Nexeon technology can be used over a wide range of vessels and deliver benefits over a broad range of operating conditions.”CW
