    Abstract

    A novel fatigue analysis procedure is introduced for offshore floating structures. It is based on separation of hydrodynamic load and structural stress responses, effective fatigue load concept and response interpolation. The actual fatigue analysis is simplified to a spreadsheet calculation with a few directional fatigue effective load cases. With the present approach fatigue damage estimates are calculated at early stage of the project. Detailed information is produced on load and stress responses of structural details for design development. A limited effort is needed for updating the fatigue life estimates as the design and stress and load analyses become more accurate.
