PROPULSION UPDATES

Mermaid Podded Propulsion Installed

Sedco Express — the first of a new fleet of DPS3 semi-sub- mersible oil and gas drilling explo- ration rigs for operation in depths to 8,500 ft. — is the first use of the

Mermaid podded thruster drive in an offshore application. Mermaid was jointly developed by Kamewa and Cegelec. The system aboard

Sedco Express consists of four sets, each comprising synchronous 7

MW AC motor, pod cubicle and slipping unit, large and small pod domes, 12 pulse synchroconvertor and 11 kV supply transformer. "And with greater accura- cy! TheSSS-lOOKisthe only low cost side scan that conies with a built-in IT thermal printer as standard equipment and a full set of operator controls to give you complete control of the unit It has a range of 1,800 ft. on each side, and comes complete with fish and tow cable."

Mermaid units reportedly can reduce required generating capaci- ty by up to 17 percent, and cooling requirements by about 25 percent.

Mermaid units are designed to save time and money on the repair and maintenance fronts as well, as the units can be fitted and replaced underwater. Shaft seals and propellers can also be changed underwater. For the project,

Cegelec was tasked with a wide range of vessel power and control systems, including the overall power system, the AC drilling package, integrated control sys- tem and dynamic positioning equipment. The dynamic position- ing (DP) system consists of a thruster, power system and opera- tor interfaces, hydro-acoustic posi- tion reference system, DGPS sys- tem, anemometer, gyro compasses and vertical reference units for automated control of the vessel's position. The DP system provides joystick manual control of all thrusters.
