Elliott Company Awarded Thruster Contract —Literature Offered

Elliott Company's Springfield, Ohio, operation, a subsidiary of United Technologies Corporation, has been awarded a contract to supply two Elliott White Gill Thrusters to Edison Chouest Boat Rental Company in Galliano, La.

The two White Gill Thrusters will produce 9,500 pounds static thrust each. Each will also have a triple mode of operation including manual joystick control, full follow-up dial position control, and Honeywell (TAC) 3-axis control.

The 196-foot anchor-handling and supply vessel is being built by North American Shipbuilding, Inc. in Larose, La., for offshore anchor-handling, cable-laying, and fire-fiighting service. The Elliott thrusters will be used to hold the vessel in precise position in any sea condition. The vessel is capable of holding position without the main engines, using the thruster alone.

The vessel is also equipped with two 10,000-gpm fire pumps and monitors for fire-fighting service. The White Gill Thrusters will be used to counteract the four tons of thrust produced by the fire monitors.

The Elliott White Gill Thruster is a low-lead, high-volume, axial pump capable of delivering thrusts of up to 38,000 pounds (17,000 kg) in every direction— forward, reverse, broadside, and any direction in between. It provides 360 degrees of thrust. No part of the system ever protrudes beyond the vessel's hull line.

Literature is available describing the Elliott White Gill thrusters and some recent applications.
