FPSO tankers are increasingly used for offshore oil production, because they are easy to install, remove and reuse. Even marginal oil fields in harsh environments can thus be exploited profitable. These severe environmental conditions, like the North Sea, Demand a highly reliable structural design. One of the main structural subjects is the accumulation of fatigue damage. This research program is called 'FPSO integrity', a Joint Industry Project JIP, Adegeest (May 1996). The fatigue analysis part of this JIP has three main objectives: Provide a full scale database by monitoring fatigue loads and structural responses on an FPSO in combination with measurement of the environmental conditions; Analyze and develop tools and integrate these tools in a general methodology for fatigue assessment of tankers. The methodology will be validated against results from the monitoring campaign; and Provide a database for validation and calibration of the fatigue design rules for tankers in general as have recently been issued by the classification societies.
