The Communications, Air and Missile Defence Programme (LD) of the NATO Support Agency (NSPA) has completed a major Hellenic Air Force radar project, it announced on 9 January.
The LD programme successfully replaced the main bearing of a radar antenna in a project initiated in the framework of the Vibration Analysis (VA) tests. These tests are a condition-based maintenance approach fully developed and managed by LD programme Engineers.
With this approach, the life span of the main bearing had already been extended from 12 to 20 years. The VA tests, however, showed that the bearing was approaching a critical failure zone. Timely replacement was essential to avoid that failure occurring during winter when, due to the location of the site on the top of a mountain, replacement would have been impossible. As a result of the unavailability of the original equipment manufacturer to perform the work at the required time, assistance from NSPA was sought.
Luciano Pizziolo, branch chief, said: 'The excellent technical skills and commitment of the programme staff ensured that the radar could remain in operation – otherwise the site might have been non-operational until summer 2015.'
The project was successfully completed well ahead of schedule, under budget and in full compliance with the prescribed quality standards.
