The relevance of the topic of the article is due to the growing importance of deep offshore oil and gas production, ensuring the safety of personnel during field development, as well as the preservation of the environment. Currently sharply increased depth of water mark, at which the oil and gas. Features of installation and operation of the deep sea pipeline, underwater injection systems for wells located on the seabed prove that emergency cases are closely related to a deeper water level. Archival scientific sources and documents for the period from 2010 to 2019 were studied. A search and selection of relevant literature was carried out using effective selection criteria for sources. Peculiarities of installation and operation of the deep offshore pipeline have been identified, problems and safety of personnel in the conditions of deep offshore oil and gas production and environmental safety conditions have been identified.
