MISCELLANEOUS SHIP AND MARINE EQUIPMENT N0018925Q0426
Summary
AI-generated · Aug 24, 2025Procurement of steering components for ship systems, specifically steering VFDs (Variable Frequency Drives) that control the speed and torque of electric motors in the vessel’s steering setup. These drives enable precise rudder movement and are described as reducing power consumption, smoothing steering, and increasing overall system reliability.
Also included is Z-drive marine propulsion, or azimuth thrusters, which provide both propulsion and steering with the propeller capable of 360-degree rotation. This design eliminates the need for a conventional rudder and offers enhanced maneuverability. The Z-drive operation is achieved via a gear-and-shaft arrangement that creates a Z-shaped power path from engine to propeller.

Z-drive marine propulsion, also known as an azimuth thruster, is a type of marine propulsion system that uses a steerable thruster to provide both propulsion and steering to a vessel. It allows for 360- degree rotation of the propeller, eliminating the need for a rudder and offering superior maneuverability. The name "Z-drive" comes from the Z-shaped path the power takes from the engine to the propeller, achieved through a combination of gears and shafts
