Project Supervision, Service & Maintenance
Our role was to commission the DX refrigerated cooling systems for the 4 sub-stations and later provided Supervision of the on-site contractors for Exxonmobil. As the commissioning engineers we had to replace all of the pipework for the sub-stations, which had been poorly installed and also 3 times larger than specified on the design drawings. We then pressure tested all pipe work and evacuated to remove contaminants from the system. Once all evacuation tests were passed, we charged with R407c refrigerant and completed all commissioning and documentation.
