Content available remote Ship’s Navigational Safety in the Arctic Unsurveyed Regions
High traffic of the vessels in many regions of the world pressed maritime nations to issue good quality nautical charts. Vessels could proceed safely on planned voyage using nautical chart and GPS position receiver. Above popular assumptions were right in well recognized and charted regions. But some regions were not sufficiently surveyed or not surveyed at all. In this case position fixing system was useless. The only way was to follow the vessel’s hydroacoustic equipment to find out safe route in between dangers. The goal of the author was to settle matters of the unsurveyed regions. First question was quality of the in-formation on charts and role of the vessel’s autonomous hydroacoustic equipment in safety of the navigation. Second question were safety parameters kept by the research vessel.
Content available remote Methods of Iceberg Towing
Mathematical models of iceberg towing by a ship connected to the iceberg by mooring lines are considered. Governing equations describing the towing and the tension of mooring lines in two different schemes of the towing are formulated. Stability of steady solutions describing the towing with constant speed is studied. Numerical simulations are realized to compare results of the modeling with experimental results of model towing in HSVA ice tank.
