LAUNCH AND TRIP IN TOW SURVEY HOPPER BARGEProject SummaryIn November 2007, after delivery by the ship yard in Portland, OR, the 4,500 ST inland hopper barge GINA ELIZABETH was to be towed to its owners in Petaluma, CA. Argonautics Marine Engineering, Inc. was hired for the before and after launch surveys as well as the trip in tow survey. The 254 x 55 x 14.5 ft barge and its tow gear was surveyed at the Gunderson yard. The 4,300 hp oceangoing tug RICHARD BRUSCO was surveyed at the tug owner's facility. The 1966 build tug was just out of dry dock and in excellent condition with re-built engines and new tow wires. Because of the open hopper, a Survey Certificate with weather restrictions was issued. Upon receipt of a favorable weather window, the tow departed Portland on November 23 and the barge was successfully delivered to its owners 4 days later. Similar surveys were provided for the tows of the second and third hopper barges of this series in March 2008 and January 2009 respectively.
