Coating Plays Role in Shipbuilding’s Return

João Candido

A Sherwin-Williams marine coating that requires hydroblasting, rather than abrasive blasting, for secondary surface preparation has reportedly joined Brazil’s shipbuilding renaissance.

Shipbuilder Atlântico Sul recently launched Brazil’s first ship in 14 years, João Candido, under the Brazilian government’s Program for Modernization and Expansion of the Fleet (PROMEF).

The 150,000 dwt tanker is the first of a series of 22 ships that are already on the shipyard’s order book, along with the hull of the P-55 platform of Brazilian oil giant Petrobras, according to Angelo Alberto Bellelis, Atlântico Sul president.

Increased Productivity

Sherwin-Williams reports that its Euronavy ES301 coating system, which was used for the new ship’s ballast tanks, was “a significant factor in the shipyard’s productivity as it fulfills its contract to build 10 Suezmax (able to carry up to one million barrels of oil) tankers under PROMEF for Petrobras.”

Using the ES301 coating technology, Sherwin-Williams said, Atlântico Sul “has been able to double its productivity in terms of square meters of surface prepared.” Construction of João Candido occurred while the shipyard itself was being completed.

Typically, secondary surface preparation at the block stage involves abrasive blasting to prepare steel surfaces and weld seams prior to topcoating. Sherwin-Williams says ED 301 can accomplish the same task using ultra-high-pressure (UHP) water jetting, or hydroblasting, saving shipbuilders time and money.

“Petrobras pioneered the concept of combining hydroblasting and coatings that are solvent-free and tolerant of humidity across the operations of Transpetro, its shipowner subsidiary,” Sherwin-Williams said. It called ES301 hydroblasting “the new standard for coating in the shipping industry.”
 
Pre-Construction Primer

The project also involved Euronavy zinc-free pre-construction primer. The primer was applied before undertaking block construction as a precaution against flash rust on the steel following its initial pass through an automated abrasive blasting system

Euronavy PE 31 PCP has a lower-cost projection than zinc-based primers and was the first non-zinc product to be IMO PSPC-type approved, according to Sherwin-Williams.

Atlântico Sul Shipyard, established in 2005 is the largest naval and offshore construction and repair shipyard in the Southern Hemisphere.
