Functional safety explained
A new guide explaining all you need to know about functional safety is now available from ABB.
Dual compartments protect temperature transmitters
The TTF350 temperature transmitter is suitable for heavy-duty applications in industries such as oil and gas, power, cement, waste incineration and chemical processing.
It is also replacing two ABB Masterview operator stations with two ABB Operate IT workstations.
The reduction in controller quantities results from the greater power and capacity of the new AC450s compared with the unit it is replacing.
This allows more functions to be run on one unit, cutting the number needed and saving space.
The operator stations have also been improved.
The new slim line monitors save space and also have much higher resolution graphics than the originals.
They are also Microsoft Windows based, making them familiar for operators to work with and reducing the need for training.
BP Project Manager for the Lomond project was Doug Newlands: "The previous controllers were working at 80% of their capacity and this did cause us some concerns".
"The new AC450s will only be using some 40% of their capacity so the same issues should not arise".
Because of the commonality shared by the ABB systems, all the I/O is the same, as is the software, allowing much quicker installation than a completely new system.
The new control elements will allow for future expansion of the plant and an additional compression stage is being installed during Q2 2005.
The complete control system, including the AC450 controllers, was tested in a controlled environment at ABB's St Neots manufacturing facility.
The controllers and the new operator stations were successfully installed during a planned production outage in September 2004.
Control room staff have been running new operational statistics alongside the old ones, gaining confidence with the new system and checking the accuracy of the graphics.
Operators will be able to set up the stations as they want them, arranging the display to suit their working methods and give them the data in formats to which they are accustomed.
Newlands concludes: "We are confident about the support ABB will provide for the system and that the AC450 will continue to meet the Lomond platform's control needs for many years to come".
