identification of inlet and outlet locations for cool seawater discharges from an lng facility

two-dimensional hydrodynamic and advection-dispersion simulations were carried out toidentify the appropriate locations of inlet and outlet for cool seawater discharges from the proposed liquefiednatural gas (lng) terminal using mike-21 suites of software. the model simulations were validated bycomparing the observed and simulated hydrodynamics in terms of water depths, current speeds and directions.the model is satisfactorily correlated with coefficients 0.98, 0.86 and 0.91 for water depth, current speed anddirection, respectively. the validated model was extended to predict the advection-dispersion phenomena forthe two scenarios based on positions of inlet and outlet and their discharges. the predicted results of coolwater discharges were compared to the existing environmental health and safety, world bank guidelines forlng discharge facilities. it was observed that a trade-off is required before taking engineering decisions forselecting an environmentally acceptable and energy efficient option for such cool water discharges from anlng facility.
