WINDLASS Windlass seating :- The forces acting on the windlass when the ship is anchored is much more than the mass of the windlass and hence has to be specially strengthened, the details of which are as described under and illustrated by sketch below. The deck plating at forecastle and main deck in forecastle space […]
Electrically operated windlass for ship The windlass including mooring winch machinery is common for both hydraulically operated or electrically operated equipment. In the case of the electrically operated windlass cum mooring winch the driving motor is a two speed motor controlled by a suitable pole changing device.
