Hamburg Airport -
New Aircraft deicing storage facility commissioned
After five months of construction and installation work, end of September 2012, the new facility for the storage of aircraft deicing fluids was commissioned on due time and handed over to the user. For the winter schedule 2012/2013 thus at Hamburg Airport deicing of aircrafts is ensured.
The old liquid storage tanks made of glass fiber reinforced plastic (FRP) have been dismantled and replaced by 11 new stainless steel (material number 1.4571) tank-containers with the storage capacity of 320,000 liters (84 Mgal). The services included new concrete foundations, structural steel construction for gratings and stairs, stainless steel tank container, pipe works, pumps, electrical systems, exterior lighting, lightning protection, supervisory and control data acquisition (SCADA) system, and the change of the district heating system to heat the type 1 deicing fluid (ADF Type 1).
The aircraft deicing fluids are glycol blends hazardous to water. The corresponding federal water hazardous materials act requires special measures for the case of damage. The usual but complex design consists of double-walled tanks. Through the integrated design and considering the existing infrastructure, wolf engineers + consultants could find an economic solution with single-walled tanks, which guarantees the same high level of protection. In addition, the implemented solution offers operational benefits, as e.g. samples can be drawn directly from the tank through sampling valves, without the use of suction pumps.
During design and dismantling work it was found that a broad reconstruction of the entire system was required. The old pipe works showed significant wear, rust and deposits. Manifolds and globe valves were replaced with new stainless steel (material number 1.4571) manifolds and butterfly valves. Also, the filling station to fill the storage tanks from road tankers has been replaced. The SCADA system of the entire facility has been replaced by a new Simatic S-7-300. The operation is now up to date and easily accessible via a touch screen on which the entire plant is depicted with all its technical and operational information. A network server function allows display and change of all parameters on mobile devices (smartphone), and to operate and maintain the plant from the outside. Through this remote maintenance the availability of the plant and of aircraft deicing operations increase significantly.
The type 1 aircraft deicing fluid (ADF type 1) is stored at 40°C, and at about 75°C, but it decomposes at temperatures above 80, 85°C. To avoid this in the new plant, the control of district heating from the Hamburg airport was changed so that the inacceptable heating is avoided even at high supply temperatures.
During design a 3-D data model of the entire facility was set up, from which all the drawings, isometrics and piping and instrument diagrams (P&ID) were generated. The storage tanks were designed as tank containers and prefabricated, insulated and supplied to the site with all the connections ready. On only two mornings all 11 tanks could be placed with a crane.
