abstract

The paper describes the modifications required to make the GT35 industrial gas turbine suitable for use in fast ferries as propulsion machinery. The modifications made to get the unit to meet pitch and roll requirements are dealt with, as well as the engine support system modifications.

The GT35’s capability to burn low quality, liquid fuels is discussed, and a close look is taken at the effect such fuel has on the life of the unit and the time between service.

In order to facilitate power production on the ship, the GT35 has been equipped with a starting motor which during operation is used as a shaft driven generator. The generator is driven by the low pressure rotor. Each generator can produce 500 kW, which means 1000 kW for the ferry. The effect of the arrangement on the rotor system behavior is described.

At the time of writing this paper ABB has sold 6 GT35 units for operation in 3 fast ferries. The speed of the ferries varies between 40 knots and 60 knots. At the time of writing this paper, the first of the two HSS 900 ferries for Stena Line, Sweden, has just completed its first set of sea trials.
