“The implementation of the new system also gave us the opportunity to include various sub-systems such as the UV detectors we previously used to detect heat, flames, gas and smoke, but which were not integrated into the old ESD system,” explains Jens Wedege Petersen, system operator at DONG Energy’s Gas Control Center.
“Today we employ IR detectors which are far more reliable and also faster, and which have now been integrated into the ESD system.”
“It was a logical requirement from the client that the new ESD system should be able to integrate seamlessly with the existing process control system from Honeywell, to allow it to be monitored from the central control system without any need for separate monitors and user interfaces,” explains Tom Guldbrandsen, Product Specialist, ABB in Denmark. “This facilitates the work for the operators when they, as a part of their daily routines, monitor that valves and other equipment connected to the ESD system are positioned as they should, as well as monitoring the frequent partial tests and the annual full scale test that is performed on the system. “
“In addition we have the option to manually open and close the different valves e.g. in cases where we need to isolate sections in connection with repair work or simply to close down sub-plants or sectors”, explains Erik Delf.
