Sažetak
The study researches the operational performance of the DGs (diesel generators) and the PMS (power management system) on board an offshore drilling rig. The focus of this study is the reduction of running hours, fuel consumption and CO2 emissions of the DGs while increasing the reliability, stability and performance of the power generation system on offshore jackup drilling rigs. To estimate the running hours and the fuel consumption, a Pythion simulation model is developed. The model allows the author to virtually run the engines and observe the engine behaviour. By running simulations under different operational parameters, the author can compare the outcomes of each simulation. Comparison of outcomes allows the author to determine the optimum parameters for operating the PMS. The study provides an insight into a specific problem in offshore oil and gas drilling associated with tripping and POOH (pulling out of the hole) operations. The phenomena is observed and a proposed solution to the problem is given in the form of adjustment of the operational parameters. The annual savings in the form of reduced running hours, reduced fuel consumption and reduced CO2 emissions are provided.
