With the introduction of new technologies, such as waste heat recovery units (WHRU), associated gas utilization, the energy flow coupling relationship is further deepened within the energy system of the offshore oil and gas production platform. Besides, the energy system is closely linked with the oil and gas production system, and a closed-loop relationship between energy flow and material flow can be revealed. Uncertainties of energy supply and production process may lead to system-wide fluctuations, which threaten the stable operation of the platform. Therefore, an optimal planning model of integrated energy system for offshore oil and gas production platform is proposed in this paper. Firstly, a generalized energy and material flow model is proposed, three matrixes are defined based on laws of thermodynamics, including energy matrix, process matrix and feedback matrix. Secondly, the energy-material conversion relationship between the energy system and production system of a typical offshore oil and gas platform is quantitatively described, together with the coupling between the input and output of the two systems. Thirdly, considering the energy-material balance constraints and the uncertainties of production system, a multi-objective stochastic planning model for the offshore integrated energy system is established, which takes economics and environmental protection into consideration. A Monte Carlo simulation-based NSGA-II algorithm is proposed to solve the model. Finally, the validity and feasibility of the proposed methodology are demonstrated through an offshore oil and gas platform in Bohai, China. Compared with the traditional planning method, the total cost and CO2 emissions of the proposed method are reduced by 18.9% and 17.3%, respectively.

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.
