Beskrivelse
Dette kurset vil gi en kort innføring i de viktigste aldringsproblemene som påvirker aldrende konstruksjoner og hvordan disse konstruksjonene kan vedlikeholdes slik at sikkerheten er ivaretatt. Videre vil kurset gi en kort introduksjon til vurdering (assessment) og forskjellige analyser (ULS, ALS og FLS) av aldrende strukturer. Kurset vil også kort presentere integritetsstyring av aldrende konstruksjoner.
Kurset er primært basert på læreboken / oppslagsboken Ageing and Life extension of offshore structures, Wiley 2019. Authors: Ersdal, G., Sharp, J.V, Stacey, A.
Kurset vil baserer seg på relevant norsk regelverk iht Havtil, NORSOK standarder (NORSOK N-005 og NORSOK N-006), internasjonale standarder (ISO 19901-9 og ISO 19902) og relevante DNV RP’er.
EN: Description
Many offshore platforms have been in production for several decades and have passed their original intended lifetime, but since there is still use for them, there is a need for life extension. This course will provide a brief introduction to the most important aging problems that affect aging structures and how these structures can be maintained so that safety is ensured. Furthermore, the course will provide a brief introduction to assessment and different analyzes (ULS, ALS and FLS) of aging structures. The course will also briefly present integrity planning of aging structures.
The course is based primarily on the textbook / reference book Aging and Life extension of offshore structures, Wiley 2019. Authors: Ersdal, G., Sharp, J.V, Stacey, A.
The course will be based on the relevant Norwegian regulations (Havtil), NORSOK standards (NORSOK N-005 and NORSOK N-006), international standards (ISO 19901-9 and ISO 19902) and relevant DNV RPs.
