Abstract (Croatian)

Opisan je postupak analize korozijskih istrošenja tri tankera s jednostrukom oplatom izgrađenih osamdesetih godina. Obrada podataka temelji se na postojećim izmjerama debljina elemenata trupa iz baze Hrvatskog Registra Brodova (HRB) s periodičnih suhih dokovanja i pregleda brodova u službi nakon 10, 15 i 20 godina. S obzirom da su u model unesene vrijednosti korozijskih istrošenja u različitim fazama vijeka trajanja broda određen je gubitak momenta otpora poprečnog presjeka kao funkcija vremena, uzimajući u obzir vijek trajanja zaštitnog premaza. Za predviđanje napredovanja korzijskog istrošenja odnosno općenitog trenda smanjenja momenta otpora glavnog rebra na temelju rezultata dobivenih navedenom analizom, korišten je dostupni teorijski nelinearni korozijski model. Rezultati ove studije mogu se koristiti kod planiranja inspekcijskih pregleda brodskog trupa tankera u službi.

Abstract

The paper describes investigation of global corrosion wastage of three oil tankers with single-hull structure built in eighties. Analysis of data is based on existing thickness measurements of hull elements reduction from Croatian Register of Shipping (CRS) file, gauged on periodic dry-docking and close-up surveys of ships in service after 10, 15 and 20 years. Hull girder section modulus (HGSM) is determined as function of time taking into account the lifetime of protective coatings. The obtained results are compared to the available theoretical non-linear corrosion models in order to predict the long-term corrosion wastage progression. The results of this study can be used when planning ship hull inspection of oil tankers in service.
