The specifications for each test sequence are then loaded into a DeltaV automation system, which controls each individual test. Should a fault occur during a test, pressure in vessels under test is immediately relieved to the outside through an internal piping and silencer system, and the compressed air supply for the chamber is also cut off. If the safety loops are okay, test sequences begin simultaneously. When all sequences are finished, the chamber can be opened and the items removed. During the test period, all results are logged and related curves are printed out, verifying that the test period and specified pressure levels were in accordance with specified requirements.
Every test is verified by the data recorded on each vessel tested.
The AMS software is also a valuable part of the maintenance program for the pressure test facilities to document the performance of the test equipment and identify devices that may need repair or replacement. Jan Marcussen said that the company expects to recover its investment in the test facility within the anticipated time frame, based solely on reduced energy consumption using the new procedure. However, eliminating the production bottleneck by instituting new test procedures was the major benefit. All things considered, the project has been an unqualified success, Marcussen said.
