The main criterion is the requirement for operation of subsea gas pipelines in developing main technical solutions for the preparation and transportation of gas from offshore fields. In the article were shown the results of analyzes of the treatment units and gas transportation systems in offshore conditions, and the causes of technological complications that have arisen in these processes as well as ways to eliminate such complications.In addition, the operating mode of existing separators for primary gas treatment has been studied and their low efficiency in gas was noted.Taking into account specific features of offshore conditions, the multifunctional device for complex gas preparation was developed and tested. Positive test results are given.
Key words: offshore development, gas, condensate, transport, separator, technological complications, gas drying, dew point.
