Technical data from manufacturer or class sources · not yet verified by a person

Steerable thrusters operate by allowing vessels to maneuver in tight spaces and maintain precise positions. Wärtsilä’s WST-18E model, launched in April 2024, is part of a comprehensive family of steerable thrusters designed for efficient operation in competitive maritime environments. These thrusters offer robust reliability and superior hydrodynamic performance, with power ratings ranging from 700 kW to 4900 kW. They are ideal for offshore vessels, tugs, double-ended ferries, and river-going ships. The WST-18E features compact dimensions, reliable propeller shafts, and easy-to-service design elements that minimize downtime. It also includes field bus technology and an intuitive control system with ergonomic levers, ensuring both indoor and outdoor operability. With a wide range of configuration options for drive layouts and auxiliaries, Wärtsilä’s thrusters can be tailored to fit specific vessel needs, enhancing performance in dynamic positioning or bollard pull applications.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
