Abstract: For work of hydrotechnical structures in difficulties ice condition is required the development of actions for maintenance of its careful exploitation. The results of nature research had permitted to begin the development of actions for protection from ice influence in bases structures of Tugur tide power station. The energy of tide power stations is essential alternative for thermal and atom power stations. There are on in Russia many regions with high value of tide. Particularly, Kola peninsula – the value of tide is about 4 m, Lumbov Gulf - about 7 m, Mezen Gulf - about 9 m. The essentials values of tide are observed in Okhotsk sea, for example, in Penzhin Bay - about 13 m, in Tugur Gulf - about 9 m. In the regions of these water areas are difficulties ice and climatic conditions that are considered by designation, construction and exploitation of tide power stations. The above mentioned Tugur Gulf lies in west part of Okhotsk sea. The length of lied from north to south Tugur Gulf is 74 km and the width is about 37 km. The Shantar islands from north side are natural protections by influence of ices (The tides power stations, 1994). The length of dam of tide power station with the building of station lied inside of it will be 18 km. The water will be passed as well across water aggregates as across culvert holes. For careful exploitation of aggregates including in period of Freeze-up must be developed respective actions. For reception of dates about ice conditions in Tugur Gulf by small level of scrutiny for this question (Monosov and other, 1991) was necessary the carrying out of ice-research works in Tugur Gulf. Particularly, the air and ice investigations bas carried out, including ice-mesure survey and determination of ice and water salinity. Resulting of investigations are received the dates, permitting to determine the bases characteristics of ice regime of Tugur Gulf in natural conditions.
