Propulsion Train

Assembly

Twin medium-speed engines driving controllable-pitch propellers, plus thrusters, because a dredger must hold a precise track and low speed while trailing on the bottom. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
