The client required a High Pressure Pump Unit capable of pressurising pipelines ranging in diameter between 152mm and 406mm and multiple kilometres long with a water/MEG mixture. Ensuring the internal pressure of these pipelines did not drop below a critical value was of key importance and would determine the success of the system and upcoming projects for the client. The High Pressure Pump Unit would need to fully integrate with existing vessel systems, including the vessel management system and the existing deck equipment PLC/SCADA control system.
Brimmond Group designed and manufactured a fully PLC controlled High Pressure Pump Unit. The control system within this unit was based upon the Siemens S7-300 PLC, this was chosen to complement the existing deck equipment PLC hardware, onboard the clients vessel. The unit featured a Siemens IPC277E HMI which allowed control over all functions of the unit locally.
The control system was interfaced with the existing Vessel PLC via ethernet and allowed for remote control of the unit’s function from the main control room. Various interlocks were programmed to bring a stop to certain pieces of deck machinery onboard the vessel should internal pipeline pressure approach the critical value. This interface was also used to synchronise E-stops and equipment alarms with the vessel’s SCADA ensuring that the client’s product was protected in any eventuality. The control system featured an automatic pressurisation mode, this mode constantly monitored pipeline pressure and topped up as necessary to ensure the critical low pressure was never met.
