A forward-looking sonar from Marine Electronics Ltd of Guernsey, UK, has been installed aboard a British-operated tanker as a major initiative to refine operational safety. The See Echo system was developed by Marine Electronics in cooperation with the ship owner to provide a three-dimensional image of the sea up to one kilometre ahead of the vessel. It is now undergoing a trials programme which, if successful, will result in its installation aboard other ships in the company’s substantial fleet.
