In the scientific study, the offshore oil and gas production platforms were considered after the exhaustion of hydrocarbon reserves. An alternative to dismantling is the possibility of  refitting and retrofitting prospective structures for the function of energy production. The  general problem of determining the climatic offshore oil and gas fields is also considered. For the development of maritime infrastructure, a design development was added to  complement the functionality of offshore platforms for energy production. The chosen methods for developing.The subject of the study: the subject of the study are offshore oil and gas production platforms, marine power plants for power generation and bioenergy objects.Objectives: the purpose of the study is to identify options for the use of offshore hydraulic installations in marine offshore platforms for generating energy and locating bioenergetic facilities.Materials and methods: in the course of the work, various options for the use of offshore platforms in the field of renewable energy sources are considered, without the need for disposal of objects.Results: as a result of the work, the project of the experimental energy complex of bioreactor and biocultivator EECBB and RES.Conclusions: the energy sector has the opportunity to be environmentally friendly and rely on the principles of sustainable development.

Damage detection based on changes in dynamic characteristics is considered for eight-legged k-braced steel offshore oil and gas production towers. Both experimental and analytical results are presented to improve damage detection capabilities. A 1/50th scale plastic model representing the structural system of a typical full-scale tower in 218 ft (66m) of water is used for the studies. Effects of severance of diagonal bracing members on selected vibration frequencies and mode shape parameters measurable at the deck are investigated. The effects of changes in deck mass, increase in jacket mass, and deck mass eccentricity on the selected parameters are also investigated and are shown to be different from the effects of damage.

Production units located in the Brazilian marine environment are responsible for the production of 95.7% of oil and 78.8% of natural gas of Brazil causing economic, environmental, and social impacts motivating us to construct a system of indicators as a tool aimed to improve the sustainable management practice of these production units. To date, one of the tools most used by the oil industry is the sustainability report, oriented by guidelines from international organizations. However, these reports have a corporate character being unable to help the sustainability management of production units’ activities. The indicators were selected based on a systemic approach, using current knowledge on sustainability indicators, together with the survey of aspects relevant to the operation and management of offshore oil and gas production units. This paper describes the proposed indicators and presents the hierarchical structure of the system, built on the economic, environmental, social, and operational dimensions. The application of the proposed system of indicators, based on multicriterial and multiple decision-making analyses, validates a complex decision process, providing improved sustainable management of offshore production units by identifying points for which the necessary measures and actions can be implemented. Keywords: offshore oil and gas production; sustainability indicators; multicriteria and multiple decision-making analyses.
