Development of offshore oil and gas fields on the continental shelf is fundamentally different from their development on land. High complexity, specific peculiarities of carrying out and organization of works at sea are determined by various factors, including, first of all, climatic and engineering-geological conditions. The main problems during the development of these fields are caused by high cost and uniqueness of the applied technical means as well as challenges, which are connected with the necessity of works under the water, special technologies of construction organization, ecological safety, etc. The right choice and accuracy of offshore operations have a significant impact on the cost of produced hydrocarbons. Offshore operations are a set of technical and technological activities for transportation, assembly, docking and installation at the point of operation of the offshore oil and gas facility or its components, performed while the object is afloat, or using floating crafts.
The implementation of offshore operations projects in the fields of Vietsovpetro JV is associated with the creation of complex engineering structures both onshore and offshore, the operation of specialized vessels, technical facilities and special equipment. The article describes the stages of oil and gas field development, design, construction, operation, liquidation of offshore facilities and subsea communications of Vietsovpetro JV fields. The characteristics of production conditions, the principle of selection of technical means to perform work both at the onshore construction site and for offshore operations at sea are given.
