Figure 2.3. Location Map showing the Solwara 1 discharge site (top) and the bathymetric profile of the Eastern Bismarck Sea (bottom left) and the specific discharge location (bottom right). The peak behind the discharge location (bottom left) is Duke of York Island. The large active submarine volcano North Su can be seen as a conical peak behind the discharge location (bottom right).

3 RESULTS AND DISCUSSION 3.1 Dilution Thresholds Two dilution thresholds were used in this study to determine the plume extent from each discharge option (scenarios). Key dilution ratios used in the modelling were 1/300, 1/600 and 1/5,000. These key dilution ratios were used in the discussion and presentation of modelling results. The discharge water undergoes pre-dilution with ambient seawater at the surface by increasing the discharge from 758 m 3 /h to 909.6 m 3 /h, hence the model is set to an initial concentration of 833,333,333 PPB of production water. Therefore the target dilution ratios equate to plume concentrations as follows: • Pre-dilution is 833,333,333 PPB or 83.33% of the discharge stream • 1/300 dilution is 3,333,333 PPB • 1/600 dilution is 1,666,667 PPB • 1/5,000 dilution is 200,000 PPB The plume was modelled using a non-reactive tracer within the CHEMMAP system. 3.2 Plume dynamics The discharge configurations tested using the modelling were two extremes in discharge temperature and 5 parts returning production water and 1 part surface seawater. The orientation of the end pipes are designed to face vertically upwards to maximize the initial mixing of the discharge due to the turbulence associated with a large discharge stream. If the pipes were facing downwards, this initial mixing zone would be limited by the close proximity of the bottom to the outfall site. Two scenarios were conducted, one representing the potentially cooler discharge stream, 5.8°C and the potentially warmer discharge stream, 11.4°C For each scenario, 100 simulations were conducted (using the CHEMMAP stochastic model) for both temperatures for comparison purposes. From the 200 in total simulations conducted, some were selected and examined in detail to determine the dynamics of the plume created by the two extremes in discharge temperature as follows.
