POSSIBILITY OF CORROSION MONITORING ON SHIP'S STEAM PIPING SYSTEM USING OPTICAL FIBER TECHNOLOGY

The life of a ship has been limited, among other things, because she has been exposed to aggressive environments. Kinetics of corrosion on the ship's hull can be monitored properly, and there is a possibility of a prompt action. On the other hand, there are components and elements of the ship's system with significant limitations in monitoring and in the possibility of action. Among such systems is the steam piping system where the occurrence of the corrosion processes presents a hidden danger that is often neglected. The control and maintenance of the steam piping system cannot always be carried through by conventional methods because of its inaccessibility. The aim of this article is to describe the possibility of a real time monitoring of the corrosion process at inaccessible and dangerous space on board ships using fiber optic technology. A better insight into the onset and progression of corrosion by using the innovative monitoring techniques will enable an improved planned maintenance and enhance the safety of the ship and the crew.Original Abstract: Zivotni vijek broda ogranicen je, izmedu ostalog i zbog njegove izlozenosti agresivnoj okolini koja ubrzava koroziju metalnih dijelova broda. Kinetika korozijskih procesa na trupu broda moze biti pracena na odgovarajuci nacin sto daje mogucnost promptnog djelovanja. Nasuprol tome, postoje komponente i elementi brodskih sustava sa znacajnim ogranicenjima u nadzoru i mogucnosti djelovanja. Medu takve sustave ubraja se i sustav cjevovoda pare gdje pojava korozijskih procesa predstavlja skrivenu opasnost koja je cesto zanemarena. Nadzor i odrzavanje sustava cjevovoda pare nije uvijek izvediv uobicajenim metodama zbog njihove nepristupacnosti. Cilj ovoga rada je opisati mogucnosti pracenja korozijskih procesa na nepristupacnim i opasnim mjestima u realnom vremenu uporabom svjetlovodne lehnologije. Bolji uvid u nastanak i kinetiku korozije s inovativnom tehnikom pracenja omogucit ce poboljsano planirano odrzavanje i povecanje razine sigurnosti broda i posade.
