The harbor also receives tankers for the discharge of petroleum products such as gasoline, kerosene, diesel, heavy fuel oil and bitumen (a binding agent made from petroleum).
Demand for increased safety and realtime logging
The previous manual pressure logging via visual inspections of the manometers only took place once an hour and was therefore not adequate for continually ensuring and verifying that the pressure in the lines remained under 7 bars throughout the process. Umeå Harbor had requested a new solution that would give them continuous surveillance of the process as well as the possibility of storing data from each discharge. Lars-Eric Fjellvind at WSP Automation Umeå presented a solution for the continuous measurement of the pressure.
WSP Automation suggested a solution in which the pressure indicator was mounted up against the manometers, which were then connected to a computer inside the work shed. Each change in pressure was logged in the computer and saved in Wonderware Historian, in order to be able to easily produce statistics upon demand.
