A twin-hulled ship is powered by a gas turbine engine in each hull, the engine being located near the waterline in vertical alignment with a position outboard of the superstructure's internal sidewall, but preferably inboard of the superstructure's external sidewall. This is facilitated by the outward bulge of the hull relative to the superstructure's external sidewall. An air inlet filter bank is mounted in the side of the superstructure sufficiently far above the waterline to avoid swamping. Air intake ducting leads from the filter bank to the engine, and exhaust ducting leads from the engine to an exhaust outlet at a higher level than the filter bank. This arrangement enables intrusion of intake and exhaust ducting into the main loading deck space to be avoided while minimizing deviation of intake and exhaust ducting from a straight line path. Preferably, to minimize spoiling of the lines of the ship's sides, the filter bank and the intake and exhaust ducting are housed entirely between the superstructure's internal and external sidewalls. |
