The gas compression units in the processing plant are used for various purposes. Compression of the associated gas is designed to adjust for the different operating pressures. In addition, the injection of CO2 into oil reservoirs is used for enhanced oil recovery (EOR) and/or reduction of environmental impact. These systems utilize dozens of megawatts of electrical energy and intercooling for each compression stage. Therefore, the equipment used is energy-intensive and not thermodynamically efficient. An Organic Rankine Cycle (ORC) technology produces electrical energy from heat sources with low to medium temperature levels (90°C -150°C). In the present work, a model of an ORC integrated with the intercoolers of the compression units is used to simulate the energy conversion of the system. Next, various working fluids, such as R123, nbutane, n-pentane, hexane, and n-heptane, are considered. The results show a possibility of net power generation by R123 ORC of up to 40 MW. Furthermore, only an increase of 0.95% in the CO2 molar fraction of the flue gas leads to an increase of 1.29E8 kJ/h in the cooling demands of the CO2 removal and compression units. Moreover, the presented increase in cooling demands creates the possibility of net power generation of up to 41 MW by ORC. Furthermore, in terms of footprint, this integrated system can be implemented in onshore structures and with some modifications in the condenser in offshore plants. Finally, this integrated system reduces environmental impacts by generating power from waste heat sources.

“…The traditional production model with the drilling platform as the core has been rapidly transformed. The new production model gradually adopts the floating production storage and offloading (FPSO)-based system [5], which integrating offshore crude oil extraction, storage, and initial processing of crude oil [6]. The off-shore oil collection and transportation system include drilling platform, FPSO, unloading port, and special oil tankers (referred to as shuttle tankers).…”

The near-sea offshore oil extraction and transportation system use heterogeneous fleets to transfer crude oil from the floating production storage and offloading to the land-based oil storage port. Based on the characteristics of this system, the short sea inventory routing problem is investigated considering the shuttle tanker fleet and inventory management. In order to minimize the total operation cost and maximize the system reliability, a semi-continuous model for the shuttle tanker scheduling problem is established. The model optimizes the tanker scheduling plan and the design of the tanker fleet. To solve the complex model, this paper proposes an improved non-dominated sorting genetic algorithm with differential evolution operator to solve the optimization of the multi-objective model. This research also uses public vessel operation data to test the modeling and optimizing efficiency. The Pareto Fronts associated with the total operation cost and the system reliability from the optimization outcome is analyzed to provide scheduling priority advice. The results indicate that proposed optimization algorithms are effective, and the operation could be optimized with the proposed model and algorithm. INDEX TERMS Maritime inventory routing problem, non-dominated sorting genetic algorithm (NSGA-II), offshore oil transportation, semi-continuous model, shuttle tanker, system reliability.

“…Integrating RE into FPSO hybrid power systems is becoming more important due to the demand for sustainability and the need for reducing greenhouse gas emissions. Alternative options for this integration may include wave energy converters, solar PVs, and WTs but these options are influenced by the FPSO's location and environmental factors [187].…”

“…The power system of FPSO needs a consistent and dependable energy source to run its production instruments, safety measures, and crew quarters [188]. Utilizing REin place of the conventional fossil fuels not only significantly reduces carbon emissions but may also result in long-term economic savings [187,189]. However, it is crucial to guarantee the reliability and security of an FPSO's power supply [146], especially when incorporating RE sources [190].…”

The incorporation of Renewable Energy (RE) into the conventional standalone power system of an Oil and Gas (OG) platform can result in a significant reduction in operational cost and emissions. Whereas, the penetration of renewables into the conventional power system can cause serious instabilities due to the intermittent nature, especially in the standalone hybrid power systems. Therefore, the flexibility of the conventional power system should be assessed before, to accommodate and compensate for the variable renewable power penetration. In this thesis, a novel method is introduced to economically dispatch the generating units of the Standalone Hybrid Power System (SHPS), while ensuring the power system security. This method considers (a). the efficiency curve of Gas Turbine (GT) to simulate the robust real world scenario, (b). the Rate of Change of Frequency (ROCOF) and Spinning Reserves (SR) constraints to enhance the system security by restricting the frequency deviation during the contingency events, and (c). the flexibility analysis of the conventional standalone power system of an OG platform to access the ability of the power system to accommodate the demand and RE variations. A novel method has been developed and implemented in a Python-based tool, LGridPy. This method adopts the Mixed-Integer Nonlinear Programming (MINLP) technique to minimize the overall operational cost (including fuel, startup, shut-down, and maintenance cost) of the power system for the Economic Dispatch (ED) problem. It uses the MindtPy solver, which leverages the Gurobi solver for the MINLP and the IPOPT solver for the NLP. The new method considers various Key Performance Indicators (KPIs) and flexibility indicators for the power system model, to access the response of the system under different conditions and case studies.
