Raytheon Australia have contractual oversight of the operation and maintenance requirements for the Harold E. Holt (HEH) communication station in Exmouth, Western Australia. This communication station is an Australian Defence Force (ADF) asset which provides an integral function for the submarine branch of both Australia and its allies. Due to its very low frequency (VLF) transmission, 19.8kHz, and high-power output of approximately 1-1.6MW, it services the Southern Hemisphere, particularly the western Pacific Ocean and eastern Indian Ocean. Specifically, this base provides an integral function for the ADF and its allies to maintain strategic control within its sovereign space.

To maintain this function, the communication station requires maintenance and upkeep. One of the pertinent factors which has, and still is, being considered are the guy wires which support the extremely large tower networks that support the VLF array. When in its ‘as-maintained’ configuration, the structure is stable, reliable, and able to withstand extreme environmental conditions. However, when maintenance on the guy wire support network is required, there is uncertainty as to what stresses are being absorbed by the tower and whether these stresses are reaching critical values.

This project seeks to utilise numerical analysis, via finite element methods, to construct a representative model of a typical tower structure and provide a founded insight into what stressors are being imparted under various guy wire and antenna array configurations.
