Elliott Awarded Additional Contract For Thruster Unit

Elliot Company's Springfield, Ohio operation, a subsidiary of United Technologies Corporation, has been awarded a contract to supply a thruster to Woods Hole Oceanographic Institute, Woods Hole, Mass.

The unit, which is the fourth Elliot White Gill Thruster contracted by Woods Hole Oceanographic Institute within the past several years, will be retrofitted into the research vessel R.V.

Atlantis II to replace a tunnel thruster. The vessel will act as a mother-ship to a small submersible.

During such operations, propellers cannot be operated due to the danger of cutting life support lines.

The Elliott White Gill Thruster is a low head, high axial pump capable of delivering thrusts of up to 38,000 pounds (17,000 kg).

It has no external propeller, but provides 360 degrees of thrust without extending beyond the hull lines of the vessel. The main engines of the Atlantis can be shut down, and the Gill unit will be used to provide thrust in precisely the amount and the direction required to maintain a steady position or to maneuver with ease to extend the range of the sub.

The Oceanographic Institute's other three Elliott Gill Thrusters are also used on vessels requiring precise dynamic positioning. Sea trials for the R.V. Atlantis II are scheduled for March 1983.
