Abstract

Apparater og fremgangsmåter for å overvåke belastninger på stålstigerør i kjede (SCR) er beskrevet, hvor det er tilveiebrakt en flertrådet, optisk kabel som strekker seg ned langs stigerøret og flere deformasjonsfølere med optiske fibrer er installert på ytterflaten av stigerøret, idet følerne er forbundet til den optiske kabel. Følerne kan være forhåndsinstallert på nye stigerør, eller postinstallert på eksisterende stigerør ved å bruke fjernstyrte fartøy.
