Sammendrag
The first part of this thesis will present the principle of fatigue, vibration and damping of service pipes on the Norwegian continental shelf. Thus us used for the creation of a screening methodology for prioritizing service pipes with regards to susceptibility to fatigue damage. The methodology provides the user with a toolset for identification and evaluation of the various service pipes in operation. An acceptance criterion of a damping ratio of 0.3 for service pipes has been identified. Pipes with a damping ratio lower than 0.3 has been shown to experience high amplitudes in the case of resonance freqiencies.
