5.3.2 Technical codes of practice 
The technical codes of practice for support structures are listed in chapter B2.3.1. 
For information on the design of the structural steel part of the operational structure for off 
shore stations, reference is made to Appendix 5. 
5.3.3 Requirements and necessary verifications 
The following points shall additionally be shown for the operational structure (topside): 
• Load calculation for the operational structure of the offshore station (topside) 
• Definition and consideration of transport and installation states 
• Compilation of the structural analysis of the final design for primary support structures 
• Compilation of the structural analysis of the final design for secondary support structures, 
such as the work platform, boat landings, cranes, helicopter landing pad 
• Implementation documents (plans, corrosion protection systems etc.) 
• Verification of construction states and 
• Collation and submission of the approval documents for the individual Technical Approval. 
5.3.4 Documents to be submitted to apply for the 2 nd release 
[Doc. No. 520] Inspection report on the load handling concept, fire and explosion protection 
concept, access concept and space utilisation plan for the different decks of 
the operational structure (topside) 
[Doc. No. 521] Final design of the primary and secondary support structure 
[Doc. No. 522] Inspection report on the final design 
5.3.5 Updating the concepts 
The following concepts shall be updated and expressed in a more concrete form: 
• Load handling concept 
• Fire and explosion protection concept 
• Supply and waste disposal concept with the following content: 
- Bunker and refuelling concept 
- Storage of hazardous goods 
- Waste disposal concept and 
- Catchment and drainage systems 
• Evacuation concept 
• Concept for emergency accommodation and accommodation modules 
• Approval concept for components and systems 
• Plan for monitoring the production and installation and 
• Concept for onshore trials (if available). 
The documents listed shall be submitted to the appointed inspector. The documents shall clearly 
show how the protection objectives are achieved. The documents shall have a level of detail which 
allows them to be aligned with the production. The appointed inspector shall carry out an inspec 
tion and compile a respective verification report which shall be submitted to BSH.
