Abstract:

Offshore drilling operations have been done worldwide using several types of rigs. All activities and practices should be optimized to follow the important challenge which is rig costs optimization while offshore field development. Regarding South Pars water depth which is shallow, consequently jack up rigs are used to develop oil and gas reservoirs. Safety parameters are absolutely important especially in offshore practices. An artificial water curtain system is composed of a network of spray water cooling system. This system is utilized to limit the heat and noise radiation of burner and flare flowing on the rig. Numerical simulator has been developed to evaluate the performance of water curtain under various assumptions on offshore rigs. These assumptions include water curtain length, spacing of nozzles, water flow rate and pressure and etc. Simulations including heat radiation modeling and performance evaluation.Results show heat radiation is strongly affected by the spacing of water curtain and structure of the nozzles. The installed burner booms and flares varies with different types of offshore rigs, which suggest that the distribution of water curtain pipes along the rig is also variable. Nozzles and water curtains should be located where maximize the cooling system efficiency to improve rig lifetime in field development period. Our results provide a significant consideration to design cooling system and select proper structure of offshore rigs
