The first installation of the recently developed Mitsubishi TONAC total navigation control system has been carried out on the 237,000 d.w.t. tanker Heiwa Maru. The system is programmed with the 85 charts used for the navigation of the ship between Japan and the Arabian Gulf; it, therefore, picks the relevant chart for the current position and displays it. A collision prevention system has been built into the machine which processes radar and chart data to determine when a potentially dangerous situation will develop. The machine will also compute the programmed route along with the ship's draught and sea depth, obtained from the chart, to determine if possible stranding situations will arise. Taking all these factors into consideration, as well as the meteorological and current conditions, the navigation system is thus able to steer the optimum course for the ship, resulting in less distance travelled to give a saving in fuel.
