Auto Transfer System 13.8KV – Offshore Application

		Scope of supply: code development, liaison, simulation, commissioning and O&M document – to operate on the clients chosen hardware platform. The “Piper Bravo” North Sea oil production platform supplies electricity via two undersea cables to the unmanned platform “Saltire”. The system had to ensure that “Saltire” made the correct decisions when choosing one of the two undersea electricity supplies or opting for the on-board emergency generator supply. The huge financial and production costs of a supply failure required the flawless performance of the control system. The PLC was responsible for monitoring and controlling the operation of HV air circuit breakers on both “Saltire” and “Piper Bravo”. The final solution was achieved after extensive liaison with multiple responsible organisation and engineers. To ensure the PLC solution met all the requirements a witnessed simulation was performed allowing the observation of the entire process.
