population energy needs. Our thermal insulation coatings are being used to insulate equipment to reduce heat loss and increase energy efficiency in existing nuclear facilities.

“Additionally, there is a need for lead
abatement in facilities that are being de-
commissioned,” said Crolley. “Nansulate
coatings provide cost effective thermal in-
sulation properties that stand up well to ex-
treme environments, as well as the ability
to easily encapsulate lead contaminated
surfaces for environmental remediation. We
have already begun initial projects in the
U.S. with facilities using our nanotechnol-
ogy-based products. Power generation fa-
cilities, including nuclear, coal, oil and gas,
wind, wave, and solar will continue to be a
market focus of ours this year to expand
the foot print of sustainable nanotechnol-
ogy and the benefits it can offer for energy
efficient power generation.”
The U.S. Department of Energy esti-
mates the world commercial nuclear gen-
erating gross capacity could increase
from 2005 levels by 35 percent in 2015
and by 70 percent in 2030 (U.S. Depart-
ment of Energy, 2006.). Of approxi-
mately 439 nuclear power plants that
currently operate in thirty countries, the
United States, France and Japan operate
about half. Currently, an additional 33
plants are in the process of being con-
structed with another 94 planned, and
222 proposed by countries ranging from
China to South Africa, according to a
2008 report by The Wharton School,
University of Pennsylvania.

ing for coating systems at one of the IMO-approved test institutes—COT in the Netherlands—passing with several tank coating systems. Two test methods are utilized. The first test simulates the composition of the vapor phase in crude oil tanks both in ballast and in fully loaded condition. The second test simulates immersion in a crude oil tank with a model liquid developed to replicate some of the most corrosive crude oils.

According to Jorunn Holdhus Skovly,
Jotun’s product manager for
tankcoatings, Jotun coating sys-
tems performed well in these rig-
orous tests. “Jotun welcomes the
IMO regulations as they ensure a given
standard for the whole coating process,
from steel preparation to control meas-
ures,” she said. “Type approval for coat-
ing systems ensures that our customers
can trust they are selecting appropriate
and high-performance coating systems, fit
for purpose.” CW

Jotun’s protective coatings pass the IMO PSPC COT rules for protecting tanks against corrosion

Jotun recently completed testing of coating systems consistent with the new IMO PSPC rules for cargo oil tanks (COT), scheduled to come into force next year.

The new IMO PSPC rules for cargo oil tanks (COT) will go into effect January 2013. Focused on maintaining the long-term integrity of tanks, the new standard requires that all coatings used in the tanks must provide long-term protection against the corrosive effects of crude oil.
