WORKBOAT ANNUAL Trico Revives Sunken Workboat After sitting at the bottom of the Mississippi River for 14 months as a result of a collision with an ocean-going freighter, workboat M/V Galveston was recently raised by Trico Marine Operators, Inc. Trico executives opted to refur- bish the newly-raised vessel — now re-christened M/V Stones River — with the help of Eastern Shipbuilding Group. The eight- month refurbishment effort includ- ed major upgrades along with a midbody modification to extend the vessel from 170 to 220 ft. (52 to 67 m). Trico turned to Woodward Governor Company — a worldwide designer and manufacturer of industrial con- trols for engine efficiency solu- tions — and Gerhardt's, Inc.

For speed control on Stones River's two rebuilt EMD engines and its Detroit Diesel bowthruster, Gerhardt's supplied three Woodward 701A Digital Speed Controls 16-bit microprocessor- based digital controls for enhanced dynamics. Gerhardt's also provid- ed two Woodward PG-12 R actua- tors to work with TYico's EMDs and Woodward's 701A Digital Controls and a Woodward EG-3P actuator for the Detroit Diesel bowthruster. New Woodward 701A Digital Speed Controls replaced the Stones River's old PGA hydraulic governors. The new controls are faster and pro- vide better transient and steady- state performance. According to Gerhardt's Application engineer Kenny Dennis, the 701A controls offered the benefit of fewer moving parts, a significant preventive- maintenance advantage. "It was cheaper for the shipyard to install all-electronic speed set- ting units like the 701As (digital speed controls) than it would have been to install the older PGA gov- ernors since the older technology requires pneumatic lines/tubing from the wheelhouse," commented Mr. Dennis. "Trico executives were impressed at how quickly the 701A controls responded to speed transients." Trico's decision to retrofit Stones River is typical of the recent resur- gence of activity in the Gulf of Mexico. "To respond to the market, com- panies are working hard to ready vessels as quickly as possible," said Les Casterline, Gerhardt's director of Sales and Marketing. "Using controls like Woodward's 701A Digital Speed Controls can help companies reduce or mini- mize maintenance expenses while increasing equipment reliability." Stones River is reportedly the first offshore supply vessel equipped with digital controls on the main engines and more are in the works. Gerhardt's has two more Trico 701A Digital Speed Control projects in the works. Circle 291 on Reader Service Card Circle 289 on Reader Service Card Maritime Reporter/Engineering News
