Rally completed hydraulics on the options to determine the optimal flow path to the observation well. Additional process calculations confirmed that additional cooling was required to ensure the disposal water stayed below the maximum temperature allowed on the existing piping section. The mechanical team assessed what was necessary to meet CSA Z662 requirements. The new pipeline routing and basic design basis was completed for both the above and below ground sections. Freeze protection, buoyancy, and cathodic protection were considered in the pipeline design. Impacts to the existing electrical infrastructure were assessed, and necessary modifications were added to the scope. The scope also included assessments to ensure the existing control systems could accommodate the new automation and instrumentation requirements.
A Scoping Study report and DBM report, complete with capital cost estimates, were completed prior. As part of the DBM scope, a project risk register was developed and maintained. A project milestone schedule was developed as part of the DBM. Value engineering was utilized to consider methods to save on capital and operating costs.
