Abstract

A chain mooring windlass may include a frame, a wheel, and an axel extending through the wheel and rotatably coupled to the frame. Drive assemblies may be coupled to the axel via a first stage gear reduction including reduction gears. The axel may be coupled to the wheel via a second stage gear reduction including reduction gears. A movable drive mechanism may include reduction gears, and drive assemblies coupled to the reduction gears. The drive assemblies may drive the reduction gears. A drive gear may be coupled to the reduction gears. The reduction gears may drive the drive gear. The drive gear may be configured to couple to a chain wheel of a chain mooring windlass to drive the chain wheel. A chain wheel coupler may be configured to selectively couple the movable drive mechanism to a chain wheel of a chain mooring windlass.
