Abstract
In the present study a requalification scenario of an existing offshore steel jacket platform (fig.1) has been investigated (ref./1/). The requalification process of an offshore structure brings together structural and reliability analyses, inspections data interpretation and rational inspections planning over the operating life; it is a key aspect in the management of a platform for several reasons:
-
many platforms have reached their design service life;
-
some of them are still temporarily manned;
-
structures installed before 1970 have not been designed taking into account fatigue phenomena;
-
the employed reliability analyses allow explicit consideration of specific damage conditions observed through inspection;
-
it is possible to optimise inspection costs, frequencies and acceptable risk level.
