Project Description

FATIGUE RESISTANCE OF JACKETS

Evaluation of fatigue resistance of offshore jacket joints by numerical approaches

Year: 2019

Jacket structures that are subjected to a cyclic loading below the yield strength are still susceptible to fail. The phenomenon that causes failure when the cyclic loading is acting long enough, i.e. for a certain amount of cycles, is called fatigue.

In this project, a detailed fatigue analysis is conducted to confirm that the weld design ensures an adequate fatigue life of the joint. This analysis is developed in accordance with DNVGL-RP-C203 – Fatigue Design of Offshore Steel Structures.
