Delta Shipyard Delivers 120-Foot Seismic/Utility Vessel To Shell Oil
Delta Shipyard, a unit of Chromalloy American Corporation, has announced the completion of the M/V Echo, a seismic/utility vessel for Shell Oil Company. Primarily for use in the Gulf of Mexico, the M/V Echo is designed for shallow-water operation with a minimum draft of 5 feet 6 inches.
The Echo will enable engineers to determine the prospects of oil reserves near coastal areas where deep-draft vessels were previously unable to venture.
The Echo measures 120 feet in overall length, 36-foot beam, with a hull depth of 8 feet. Being a triple-screw vessel, her propellers are driven by three General Motors 12V-71 diesel engines rated at 240 horsepower each at 1,800 rpms, through Twin Disc MG 514 reduction gears. Slow-speed maneuverability of the vessel is increased by use of The Waterways Company Steermaster Bow Steering System using a GM 4-71 engine developing 120 horsepower.
All engine controls are manufac tured by WABCO. The steering system was designed by Skipper Hydraulics.
The Echo is equipped with two radars—Decca 916 A and Decca 101. Navigation of the vessel is aided by the installation of a Sperry Auto-Pilot and Gyrocompass. Equipped with a complete galley and accommodations for 22 men, the Echo can support 24- hour seismic activities in the coastal areas.
