The process is monitored from a modern control room at the control centre in Nyhamna. A curved wall with a large screen display provides the operators with a good overview of the process facility. Camera monitoring of process sections is also integrated into the safety and automation system.
The system is a huge 800xA system with 28 operator workplaces and eight engineering stations, requiring 42 servers in six cabinets for the process automation and information management system. Control room, “collaboration” consoles and equipment and the large screen is also supplied.
The process has 15,000 I/Os in total, and the I/O communications protocols at field level are mainly on HART and Profibus.
The process is monitored and controlled by 67 AC 800M controllers (43 Single AC 800M, 12 single AC 800M HI and 12 redundant AC 800M HI), controlling Process Control, Process Shutdown, Fire&Gas, HVAC, Power Distribution Control System, Subsea Control Units and Fire Water Pumps. In addition, there is supplied two Safe Guard systems for Emergency Shutdown and three Anti Surge systems.
A redundant PPS (Pipeline Protection System), which monitors the pressures in Langeled, communicates with the process automation system facility at Nyhamna via a Modbus protocol.
The simulator system covers most areas of the Process Control, Process and Emergency Shutdown, some Fire&Gas areas, Power Distribution Control System, Subsea Control Units, Anti Surge and simplified metering.
Production of control cabinets was carried out from the summer of 2004 to the autumn of 2005, and control logic programming was finished the summer of 2006.
