scope:

This AD 2000-Markblatt can be used to provide verification of stability of skirt supports on vessels. The verification shall be carried out separately for the local loadings at the skirt-to-pressure vessel junction, for the skirt itself and its anchoring in the foundation.

Stress intensification within the meaning of 4.5 of AD 2000-Merkblatt B O in the pressure-relating shell are to be expected, particularly in the case of low pressure loading (eID < 0,005) as well as in the case of high additional moments, for example due to wind loads (HID > 5). Below these limits it may be necessary to perform a stress analysis if additional loads are extreme (e.g. due to additional weights, high-density filling weights or high eccentricity in the event of transverse acceleration) or if the design principles do not match the design variants dealt with in this AD 2000-Merkblatt.
