Abstract
Oil platforms are complex structures used to host workers and equipment needed in the offshore exploration. This work focuses on the platform's heat and electricity cogeneration plant, which supplies a process heat exchangers net, and provides the necessary electricity for all the equipment used for the process and worker's accommodation in the platform. The platform demand with maximum load is 75 MW, which could be achieved using four gas turbines (25 MW each), one of which is kept for backup purposes or using six dual fuel engines diesel/natural gas (15 MW each), one of which is also kept for backup purposes. Therefore, thermodynamic analysis were performed comparing the two traditional configurations (gas turbine and dual fuel engine diesel/natural gas) and a combined configuration. The combined configuration is composed of three gas turbines and two dual fuel engines diesel/natural gas (one of the gas turbines kept for backup purposes). The objective was to mitigate the weak points of each option and increase the efficiency of the cogeneration plant, also expecting lower CO2 emissions.
