MEASUREMENT OF ICE THICKNESS IN THE SEA PORT WATER AREA USING PICOR-ICE DEVICE

A difficult ice situation had developed during the winter navigation of 2017/2019 in the waters of the seaport of St. Petersburg, near the St. Petersburg oil terminal and in the Golden Gate area of the St. Petersburg sea channel. Large and small ships had been getting stuck in the channel with fast ice and icebreakers and tugboats had been having to free the ice channel. The use of radar equipment for remote measurement of the ice thickness in the channel with fast ice had helped to solve this problem. In the winter navigation of 2017/2019 in the water area of Saint Petersburg marine port the series of telemetering of ice thicknesses was executed from the boards of sea vessels and ice-breakers. Researches of ice thickness, conducted with using «PikoR-ICE» radar device, are considered. Measurements, conducted on the channels with fast ice and at port berths, are explored. Of greatest interest are measurements of ice thickness in the area of the Golden gate and Petersburg Oil Terminal, where ballast bulkers and dry-cargo ships were often stuck. The measured thickness of pressed ice is 140-200 cm. Overcoming such ice thicknesses is only possible for the powerful icebreaker fleet. Information about measuring the ice thicknesses is studied on the courses of training of marine navigators on ice courses to the program of the Arctic Polar Code at the Admiral Makarov Training Center. Taking into account the opinion of navigators, it has been decided that such measuring device of ice thickness is needed on ships board in Polar waters and it is advisable to know the ice thicknesses along the vessel route at distances of 5-10 cbl with using the flying apparatus.
