Appendix 5-MI Verification states and actions 
5-111.1 Verification methodology 
The requirements and requisite verification states shall betaken from DIN EN 1990 [1], [2] and 
chapter B2.3.2. 
5-MI.2 Actions 
The following notes on actions and their combinations refer to the design of the structure in its 
final state after all construction and installation states have been completed. 
Actions or load assumptions shall generally be chosen in accordance with the DIN EN 1991 
series of European standards. 
Supplementary notes on actions, which result from gaps in and sensible additions to DIN EN 
1991 [3], [4], are provided below. 
Dead-weight and superimposed loads: 
Actions resulting from dead-weight and superimposed loads shall be taken from the technical 
specifications of the DIN EN 1990 series. 
It is recommended that the dead-weight and superimposed loads of the offshore stations 
considered here be determined by weighing them. In this case, y F = 1.10 may be used in the 
calculation.
