CLOSED-CIRCUIT TELEVISION AS AN AID IN SHIP CONTROL

A continuing study of ships bridge design and ship control conducted by the defence research board of Canada has recognized that the conventional method of issuing and executing verbal orders contains inherent delay and is a possible source of error in ship control. As a partial solution to this problem, it was proposed that the officer originating decisions to change the course and speed should implement these decisions himself through the direct control of helm and engines on the bridge. A television camera positioned on a suitably high structure, providing an image of the ship and the surrounding water, would improve visibility from the conning position. A sea trial, described in the present report, was therefore conducted to explore some of the advantages of using television displays to some the critical areas about the vessel which are otherwise blind. Systematic observations were made aboard a Canadian Coast Guard vessel with and without closed-circuit television. The primary areas of interest, in order of importance, were: use of the television as a visual aid in controlling the ship from the centre-line/ use of the television system as the only visual means of ship control, i.e. blind ship control/determination of operator difficulties in the interpretation of the television display/ possible applications of television to the duties of Coast Guard vessels, especially ice-breaking and buoy tending/ optimum arrangement and location of the television cameras and ancillary equipment, e.g. pan and tilt mechanism.
