SA Water, Bolivar WWTP, Hazardous Area Ventilation

A new gas detection and ventilation system was installed throughout hazardous area galleries at the Bolivar Wastewater Treatment Plant for the purpose of detecting and dissipating gas leaks. James carried out the detailed electrical design of a Motor Control Centre (MCC) to control each of the nineteen ventilation fans and sixteen gas detectors in the system. He was heavily involved in the factory acceptance testing and commissioning of the MCC. Additionally, he spent two months at the Bolivar WWTP in the role of construction site supervision where he managed the installation and commissioning of the final system.

APA, Orbost Gas Plant, Sole Gas Development Project

APA upgraded the Orbost Gas Plant to process gas supplied from the subsea SOLE gas field. As part of the upgrade new gas generators, switchboards and plant equipment were installed. James was responsible for the design and procurement of a Power Management System to monitor all plant loads, provide circuit breaker control and perform load shedding of ‘non-essential’ plant loads if required. James specified all panel components, designed the control system, specified the PLC logic and produced a functional description document. Additionally, James conducted the testing and commissioning of the Power Management System.
