Retractable Azimuth Thruster · Bow/Stern Thrusters
Retractable thrusters are a key component of marine propulsion systems designed for reliable operation in demanding environments. The Wärtsilä WST-24R retractable thruster is part of this family, offering innovative solutions that enhance manoeuvrability and station keeping capabilities. This thruster features an 8-degree tilted propeller gearbox, which increases the available thrust by 15–20% compared to non-tilted models, making it ideal for vessels requiring precise positioning in harsh conditions. With a power range between 750 kW and 6500 kW, the WST-24R is suitable for various applications including wind turbine installation vessels, offshore support vessels, and heavy lift shuttles. Its compact design minimises vessel resistance and allows operation in shallower waters, while its easy maintenance features ensure reliable performance even when the vessel is afloat.
