World's largest subsea motor
Hayward Tyler Ltd, a manufacturer of pumps and motors for the power and oil and gas industries, has announced that the largest subsea motor ever built has been successfully tested.
The 2500kW subsea motor is the first of three ordered by Aker Kvaerner Subsea, a provider of surface and subsea solutions for the oil and gas industry, to drive their seawater injection pumps on the StatoilHydro Tyrihans project in the Norwegian Sea. The motors have been developed in close cooperation with Aker Kvaerner Subsea.
The qualified Hayward Tyler design for the 2500 kW variable speed, super synchronous motor will operate at speeds ranging from 2500 to 4000 rpm. The subsea motors will have increased insulation (11 kV) to accommodate the electrical challenges faced by the world’s largest subsea motor and longest step out (31,4 km) from the Kristin platform.
News of these record-breaking developments has created further interest in the market and the company is now negotiating supply agreements for its subsea motors with a number of Integrators.
