The Location
COSCO Shipyard Zhoushan, China
The Challenge
Long-term anticorrosive protection for the harsh conditions
encountered in water ballast tanks
The Solution
SIGMAPRIME 700 universal primer compliant with the IMO
PSPC standard
The Benefits
Universal, premium-quality epoxy primer with excellent
anticorrosive performance, ideal for new-building projects,
including in water ballast tanks
The Result
After 5 years in service, Mariloulas water ballast tanks are in such
an excellent condition that no repair work has been required
The Challenge
Over the years, corrosion in water ballast tanks has been
identified as a major concern. This issue triggered the
establishment of a new set of regulations under the auspices
of the International Maritime Organization. This Performance
Standard for Protective Coating (PSPC) is dedicated to seawater
water ballast tanks and is compulsory for all steel ships above
500 GT, which have building contracts that were signed after July
1, 2008. Under these regulations, the coating requires regular
assessment and the service lifetime should be at least 15 years.
SIGMAPRIME 700
Outstanding ballast tank protection for long-lasting performance
The Solution
The SIGMAPRIME 700 primer is specially designed to provide
excellent and long-lasting cracking resistance, even after
multiple immersion and temperature cycles. It is not only an
ideal choice for the harsh water ballast area but also a coating
solution that reduces complexity during the new-building period.
The SIGMAPRIME 700 primer can be applied all year round to
virtually all vessel areas and in all temperatures.
The Benefits
The water ballast tank area is a critical area for the safety of the
ship and its crew at sea. It is compulsory to regularly survey the
ballast tank and conduct repairs whenever appropriate.
However, repairs in this area are very difficult due to its physical
nature: its confined space reduces accessibility and makes any
surface preparation and coating application complicated.
That is why repair costs per square meter are among the highest
in the business.
The excellent performance of the SIGMAPRIME 700 coating
provides customers with significant savings by avoiding complex
and lengthy repair procedures and by allowing the vessel to
immediately resume its commercial operations after inspection.
The Results
Top image: The water ballast tank area is vast and complex making access and
repairs very difficult. The SIGMAPRIME coating is the optimal solution for any water
ballast tank project
Middle image: SIGMAPRIME 700 has been designed for optimal edge protection:
no corrosion has been found
Bottom image: The sacrificial zinc anode is as good as new as a result of the
outstanding anti-corrosive properties of the SIGMAPRIME coating
