EDITOR'S NOTE: Several astute readers have commented that All American's claims of 'Sea Scout' being the first quad propeller catamaran are incorrect. Our readers are right. Dozens, if not hundreds of four-engined catamarans have been built in the last two decades.
All American Marine, Inc. (AAM) delivered the research vessel 'Sea Scout' to C & C Technologies, Inc. (C & C) of Lafayette, La. The 41m aluminium vessel is believed to be the first catamaran featuring quad propeller propulsion and was custom designed to significantly increase C & C’s surveying capabilities.
The design of 'Sea Scout' marks a shift for C & C, which typically operates steel monohull vessels. A high performance and versatile catamaran design was deemed most appropriate for C & C’s diverse multi-mission requirements. Getting to the site quickly means more time on the job and fewer trips offshore. In addition, the catamaran design offers enhanced seakeeping ability which allows the survey team to operate in all weather conditions.
“With this boat, we will be able to do more work in rougher seas,” said 'Sea Scout’s Captain, Jeramie Rivette of C & C Technologies. “That’s really important in survey work where pitch, roll and heave will often stop you from getting good data.”
“The challenge was to design a vessel that would run at high speeds and over long distances to reach the project site, but also a vessel that would be efficient spending a long time on low power and low speed during surveying work,” said Nic de Waal of Teknicraft Design Ltd., naval architect behind 'Sea Scout'. To meet this challenge, Sea Scout’s two engine rooms are each equipped with a C32 ACERT 1,200kW diesel engine, a C18 ACERT 412kW diesel engine and a C6.6 170 ekW generator, all supplied by Caterpillar. The vessel can travel to a work site on all four engines at a cruising speed of 26 knots. At the job site it runs on the smaller two engines coupled to ZF Marine gears with trolling valves to provide an economical speed range from 4 to 11 knots. For long range capabilities, the vessel has a fuel tank capacity of 25,000L, plus two reserve tanks provide an additional capacity of 16,600L. Ballast tanks are located fore and aft to ensure optimal trim in various loading conditions.
The 'Sea Scout’s Chief Engineer, David Wright of C & C Technologies added, “If James Bond were to own a survey boat, this would be it.”
