Rigdon Continues With Ten Boat Program

The 54-foot beam on the GPA-640 class PSV St. Louis contrasts with the narrower 46-foot beam on the GPA-654 class Triple Play in this image of the two vessels at Port Fouchon?s Seaport Terminal.

On December 7, 2007, the fourth in a 10 boat series of GPA-654 class diesel-electric platform supply vessels for Rigdon Marine, the Slam Dunk, was delivered alongside Bollinger’s facility in Port Fourchon. At the same time the fifth and sixth of the series were taking shape at Bollinger’s Lockport, La., facility on Bayou Lafourche. While at the same time the second and third in the series were working out of Port Fourchon a few miles down the road. At 190 x 46 ft., these are smaller than the 210 x 54-f.t 640 class PSVs. 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-ft. boats.
