Part В - Verifications and approval requirements 
35 
With regard to corrosion protection, the following information shall be included in the design 
basis: 
• Information on the codes of practice to be applied (“hierarchy of norms with respect to cor 
rosion protection”) 
• Presentation of the planned corrosion protection systems, i.e. which types of corrosion 
protection are to be used for which components, including general information on their re 
spective durability, as well as 
• A note stating that this shall be further specified in the corrosion protection concept requi 
red for the 2 nd release and on which the final design shall then be based. 
Information on the further requirements pertaining to offshore stations is contained in chapter 
B5.2.3. 
2.3 Design phase 
2.3.1 Technical codes of practice 
The support structures shall be designed in accordance with the Eurocode; in addition, the 
DIN standards in their respective latest white copy versions shall also apply. The BSH reserves 
the right to exclude individual standards or parts thereof from the obligation to apply the 
above standards. 
The technical codes of practice listed below shall be applied in their respective latest version. 
The following list does not claim to be complete. When applying the design standards, the 
respective requirements for offshore structures, which differ from the standards commonly 
used in structural engineering, shall receive due consideration through the inclusion of appro 
priate codes of practice (please see below). 
With regard to designing the steel components required to build the support structure of an 
offshore station, reference is herewith made to Appendix 5 (Application notes for the BSH 
Standard Design “Minimum requirements concerning the constructive design of offshore 
structures within the Exclusive Economic Zone (EEZ)”).
