Bollinger Shipyards, Inc., Lockport, La. The Knockout is the last in a series of ten 58m (190 ft) Platform Support Vessels for Rigdon Marine, Inc., New Orleans, La. The entire series is based on a GPA 654 design from Guido Perla & Associates, Inc., Seattle, Wash. At 190 ft by 46 ft, these vessels are smaller than Rigdon Marine’s previous series of PSV’s. Those 210 ft by 54-ft deepwater vessels were based on a GPA640 class. Perhaps their most distinguishing features are that the Cummins diesel engines and generators are set on the main deck level and the system operates with direct current Silicon Control Rectified current rather than the alternating current on the 210-foot boats. Alstom was selected for the diesel-electric package aboard the 10 GPA40 platform supply vessels, but EPD Ltd., Houston, Tex., worked with Rigdon Marine and Bollinger Shipyards for the GPA654 Class. All 20 of Rigdon Marine’s Platform Support Vessels (PSVs) were designed by Guido Perla & Associates. The previous GPA 640 series were built by Bender Shipbuilding & Repair Co., Inc., Mobile, Ala. The design of the DP2- and FFV1certified GPA 654s, measuring 58 meters in length, incorporates greater operating efficiency compared to similar-sized vessels, increased cargo capacities resulting from locating propulsion generators to above main deck, as well as reduced construction cost due to simplified construction methods. Designed for deepwater offshore operations, the GPA 654’s are capable of carrying 144 cubic meters of bulk material and 652 cubic meters of liquid mud in self-cleaning oval tanks. As a result of the vessel’s diesel-electric propulsion con- figuration, the standard for GPA Offshore vessels, fuel efficiency is increased, thus resulting in cost savings, lower emissions and higher reliability. DIESEL-ELECTRIC PROPULSION Back in 2005, Rigdon Marine had the foresight to select diesel-electric propulsion and was able to leverage the advantages of this system in terms of flexibility of the design and economy of operation. The diesel-electric system provides the designer with more flexibility in the development of the internal arrangements of the vessel, thus making the design more efficient. In addition, diesel-electric propulsion provides greater flexibility in the power management onboard the vessel, thus providing more efficiency and reduced The GPA 654 Class platform supply vessels feature two 1,100 hp Z-drive units on the outside and a 1,100 hp fixed thruster in the middle fuel consumption. “Diesel-electric propulsion,” says John D.
