Oy AGA AB’s owner Linde AG chose Porin Teollisuusputki Oy as their mechanical contractor for a project where an oxygen plant originally situated in Koverhar, Hanko, was moved to Harjavalta, where AGA’s plants operate in the Suurteollisuuspuisto industrial park. The materials to be moved totalled over one thousand tonnes and included service platforms, piping and other things in addition to the equipment itself. Some of the mass to be dismantled was sorted as waste.
The main compressor and the booster compressors are the largest individual equipment installations, but dozens of containers and pumps were also installed. Also the oxygen concentrating tower’s assembly welds and the dismantling and reassembly of the tower’s over 50-metre landing were significant parts of the project. After the dismantling, the pipeline was moved to Pori, to PTP’s production facilities where new pipelines could be prefabricated.
The project also included the connection of the oxygen plant to existing systems. It was completed on a tight schedule: 44 different points of connection in total were completed in four days. Because of good planning and management of material streams, the project was completed in time.
