Guido Perla & Associates said that the fifth in the GPA 654 PSV 10 series owned by Rigdon Marine was christened at Bollinger Shipyard in Lockport, Louisiana on January 3, 2008. With this multi-vessel order, which was placed in January 2006, Rigdon’s GPA-designed fleet has increased to 20 PSVs, including the Slam Dunk’s sister vessels First and Ten, Double Eagle, Triple Play and Grand Slam, which have been delivered or christened earlier this year, as well as ten 64-meter GPA 640 PSVs. The design of the DP2- and FFV1-certified 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.
