PropSpeed applied to two Chouest newbuilds

Two Edison Chouest Offshore newbuilds have been given applications of PropSpeed, a coating designed to prevent marine growth adhering to exposed metal surfaces below the waterline. In the case of the Chouest newbuilds, the coating was applied to the propellers, shafts, thruster wheels and keel-coolers.

The first of these PropSpeed application was to a newly constructed 148 ft tugboat built at Chouest's TampaShip shipyard in Tampa, Florida. The second was to a newbuild 268 ft supply vessel at Chouest's North American Fabricators facility in Houma, Louisiana.

Propspeed prevents marine growth from bonding to metal surfaces because it is slick, not because it is toxic. Originally developed for fishing fleets hunting tuna in the South Pacific, PropSpeed soon gained popularity with recreational boaters, who found that its application to propellers and running gear yielded improved performance and increased fuel efficiency.

Now the product's licensed importer and distributor, PropSpeed USA of Fort Lauderdale, Fla., is hoping that the two Chouest applications will give it a breakthrough into the commercial vessel market, where it promises the added performance benefit of foul-free keel-coolers.

Commercial vessels that are equipped with keel-coolers and coated with PropSpeed can increase their performance by keeping the grids free from marine growth, says PropSpeed USA. Cooled engine water means less engine fatigue and reduced maintenance. A metallic surface, particularly a warm metallic surface below the waterline like a keel-cooler, is a breeding ground for marine growth. PropSpeed is claimed to eliminate this problem without infringing on the keel-cooler's ability to do its job of transferring heat.

"I am very excited about the long-term benefits PropSpeed will provide to the keel-coolers and the propulsion system on both of these newbuilds," said Mark Billingsley, Technical Support Manager of PropSpeed USA, "PropSpeed is the most cost effective way to keep all types of marine vessels running at peak performance."
