Mechanical equipment used on process plants can be categorised into two main types,
namely static and rotating equipment. A brief survey at a number of chemical process
plants indicated that a number of maintenance strategies exist and are used for rotating
equipment. However, some of these strategies are not directly applicable to static
equipment, although the risk-based inspection (RBI) methodology has been developed for
pressure vessels. A generalised risk-based maintenance strategy for all types of static
equipment does not currently exist. This paper describes the development of an optimised
model of inspection methodologies, maintenance strategies, and risk management
principles that are generically applicable for static equipment. It enables maintenance
managers and engineers to select an applicable maintenance strategy and inspection
methodology, based on the operational and business risks posed by the individual pieces of equipment.
AFRIKAANS:Meganiese toerusting wat op prosesaanlegte gebruik word kan in twee kategorieë verdeel
word, naamlik statiese en roterende toerusting. 'n Bondige ondersoek by 'n aantal chemiese
prosesaanlegte het aangedui dat 'n aantal strategieë vir instandhouding van roterende
toerusting gebruik word, terwyl die risikogebaseerde inspeksiemetodologie wel vir drukvate
gebruik word. 'n Algemene risikogebaseerde instandhoudingstrategie vir alle tipes statiese
toerusting is egter nie tans beskikbaar nie. Hierdie artikel beskryf die ontwikkeling van 'n
geoptimeerde model van inspeksiemetodologieë, instandhoudingstrategieë, en
risikobestuursbeginsels wat algemeen gebruik kan word vir statiese toerusting. Dit stel die
instandhouding-bestuurders en -ingenieurs in staat om 'n instandhoudingstrategie en
inspeksie-metodologie te kies, gebaseer op die operasionele en besigheidsrisiko's van die
individuele toerusting.
