The problems of developing the northern territories for the purpose of effective use of natural resources are relevant for Russia. This article examines the materials of engineering and hydrometeorological surveys and surveys conducted in the Gulf of the Gulf of Ob. In recent decades, the problem of the reliability of water intake structures from open sources in the North, where the drift of ice, stamukhas and hummocking ice fields have a destructive effect on coastal objects, has become aggravated. In this connection, a substantiation was made about the need for special structures of coastal protection structures that would provide reliable protection for all coastal structures. The research results confirmed the need for new scientific and technical solutions, which, under such difficult natural and climatic conditions, would provide new settlements of the Yamal Peninsula with clean water and reliable protection. On their basis, effective technical solutions were prepared for the construction of water intake and water supply facilities, as well as for the arrangement of coastal zones of the Gulf of Ob. Conclusion. According to the results of the studies and engineering survey materials, a high degree of hummocking of ice fields is observed in the Gulf of Ob Bay. To combat them, special designs have been proposed, which will have to provide reliable protection to coastal infrastructure facilities.
