Abstract

Ovaj diplomski rad bavi se analizom postupaka održavanja sustava, s posebnim naglaskom na pouzdanost i sigurnost u okviru brodograđevne industrije. Cilj istraživanja bio je proučiti različite pristupe održavanju, uključujući korektivno, preventivno, održavanje temeljeno na stanju te održavanje temeljeno na pouzdanosti (RCM), pri čemu je poseban fokus stavljen na RCM. U sklopu rada primjenjena je je metoda analize kvara i posljedica (FMEA) u kombinaciji s Bayesovim mrežama (BN) kako bi se identificirali uzroci kvarova i analizirala njihova kritičnost. Metodologija je primjenjena na reprezentativnom sustavu za detekciju požara i plinova na brodu, u kojem su analizirane ključne komponente sustava, čime je ilustrirana primjena tih metoda na konkretnom primjeru. Iako posljedice kvarova nisu bile poznate niti su predložena konkretna rješenja za povećanje pouzdanosti, rad pruža čvrstu metodološku osnovu za daljnje istraživanje i razvoj u području optimizacije održavanja i sigurnosti tehničkih sustava.

Abstract (english)

This thesis deals with the system maintenance procedures with a focus on enhancing reliability and safety in the shipbuilding industry. The research examines various maintenance strategies, including corrective, preventive, condition-based, and reliability-centered maintenance (RCM), with particular emphasis on RCM. To identify failure causes and assess their criticality, the study combines Failure Modes and Effects Analysis (FMEA) with Bayesian Networks (BN). The methodology was applied to a representative shipboard fire and gas detection system, highlighting its key components to demonstrate practical use. While the study does not determine the consequences of failures or propose specific solutions for improving reliability, it lays a strong methodological foundation for future research and advancements in maintenance optimization and technical system safety.
