Bow Thruster · Bow/Stern Thrusters
Steerable thrusters are a critical component of marine propulsion systems. Manufactured by Wärtsilä, the WST Series (Steerable Thruster) offers a range of models suitable for various vessel types and sizes, with thrust capacities ranging from 200 kN to 6,000 kN. These thrusters are designed as azimuth thrusters (Z-Drive or L-Drive), featuring electric, diesel-electric, or diesel-mechanical drive options. The WST Series includes models such as the WST-14, WST-18, WST-24, and WST-32, each tailored to meet specific power requirements from 700 kW to 4900 kW. These thrusters are designed for seawater environments and are equipped with technologies like the Sternguard In-Water Serviceable Seal (IWSS), which allows for complete under-water maintenance without the need for dry docking. Regular inspections, particularly of propeller blades, seals, and hydraulic systems, are essential to ensure optimal performance and longevity. Spare parts can be sourced from Wärtsilä's global network with standard lead times ranging from 4-8 weeks, or up to 12-16 weeks for gear units.
