Control for transfer system having inhaul and outhaul winches

摘要

An automatic control system for operating the inhaul and overhaul winches of a high line transfer system automatically changes the velocity of a trolley between set landing and set transfer velocities and between set landing and set terminal velocities at a constant rate with respect to distance. Digital and graphic displays of trolley distance from a receiver ship and a supply ship and a graphic display of trolley velocity relative to the ship it is approaching are provided.
