Ship’s Navigational Safety in the Arctic Unsurveyed Regions

High traffic of vessels in many regions of the world pressed maritime nations to issue good quality nautical charts. Vessels could proceed safely on planned voyages using nautical charts and global positioning system (GPS) position receivers. The above popular assumptions were correct in well recognized and charted regions. But some regions were not sufficiently surveyed or not surveyed at all. In this case position fixing systems were useless. The only way was to follow the vessel’s hydroacoustic equipment to find out safe routes in between dangers. The goal of the author was to settle matters of the unsurveyed regions. The first question was quality of the information on charts and the role of the vessel’s autonomous hydroacoustic equipment in the safety of the navigation. The second question was safety parameters kept by the research vessel.
