Transverse Tunnel Thrusters (TT横向推进器、管隧式推进器).pdfVIP

W?rtsil? specializes in complete ship propulsion systems. Besides our marine engines, we are also well known worldwide as a designer and manufacturer of W?RTSIL?? fixed pitch and controllable pitch propellers, waterjets, gearboxes, transverse tunnel thrusters and steerable thrusters. Several thousand transverse thrusters are in operation today, the first of which were delivered back in 1964. Since 1996 W?rtsil? has produced a standard family of transverse thrusters (controllable, CT, and fixed pitch, FT) in the power range up to 3300 kW. Many operators rely on the performance of the W?rtsil? transverse thruster while manoeuvring in harbour or for maintaining dynamic positioning all over the globe. DESIGN PHILOSOPHY W?rtsil? has given top priority to reliability and durability when designing the current range of thrusters. The transverse thruster offers considerable savings in operational costs due to: ? Reliable and durable components ? Long lifetime of the bearings and gears ? High efficiency ? Maintenance-friendly design. The W?rtsil? transverse thruster design is highly standardized and optimized for use in: ? All sea-going vessels ? Special ships with high demands for dynamic positioning (DP). Although our transverse thruster is a standard design, developed to cover the practical range of applications, special designs may be required in certain cases. Barge carrier Smit Pioneer is equipped with three LIPS CT250 transverse thrusters. The passenger RoRo vessel Seafrance Rodin is equipped with four LIPS CT225 transverse thrusters. 2 We have the know-how and skills to help our customers solve such problems and construct a system tailored to their needs. The W?rtsil? transverse thruster offers major technical benefits: ? Designed with the smallest possible tunnel diameter, which minimizes the mounting space in the vessel and increases hull efficiency ? Designed for maximum thrust (within class requirements) ? H
