Abstract
Around 5% of the global offshore oil and gas production is consumed as fuel to power the platforms emitting around 200 million tons of CO2 per year. Adopting renewable energy can increase the oil and gas available for export by reducing internal consumption and opening space for the processing plant. This work presents an improvement to the classical analytical hierarchy process multi-criteria decision analysis method, where a viability check phased is introduced before the criteria weighting. The proposed methodology is then applied to a case in Brazil, where 10MW of continuous electrical power is required by a subsea CO2 separation and reinjection system to be installed at 2000m water depth and 160 km from shore. The selection criteria include technical, economic, and environmental aspects weighted with the contribution of experts. The resulting ranking is offshore wind followed by wave energy, subsea small modular nuclear reactors, and ocean thermal energy conversion.
