LAYING OF PIPELINES IN SUBSEA TAKING INTO ACCOUNT THE PROTECTION OF THE ENVIRONMENT

Abstract

This article is devoted to the construction of offshore pipelines, taking into account the protection of the environment. Initially, information was provided on the conditions of the pipelines. Then there was a discussion about the methods of laying pipelines, their pros and cons, and therefore the choice of method, which is economically viable and takes into account the environment. We know that the main factor in choosing any method of laying a submarine pipeline is economic and environmental factors. Underwater pipelines are invaluable for offshore oil and gas transportation and water supply to the islands. The construction method is very important for the installation of an expensive and time-consuming offshore pipeline and should be selected after a general consideration of equipment, capital and time. In addition, the environmental impact and safety of construction and its impact on surrounding marine operations are also determining factors. Decks, pipelines and cables, valves and switches, pumps, cleaning and all equipment must work without hindrance and must be tested repeatedly to avoid endangering people and the environment. At present, submarine gas pipelines continue to develop, accounting for 45% of natural gas exports to the west. Therefore, before the submarine is laid, the entire route along the seabed must be carefully studied, and all potential obstacles, including the sunken ship, large rocks must be identified, eliminated or bypassed. Subsea pipelines are the safest, most cost-effective, and most environmentally friendly route. Keywords: subsea pipelines, construction technologies, submarine pipeline installation, environment supervision, management and control of industrial waste, prevention of pollution, pipeline laying.
