Part B - Verifications and approval requirements 
77 
Danger zones outside the offshore station shall be taken into account and specified to the ex 
tent that hazards caused by falling parts or suchlike, by collisions, or by smoke and fire drifting 
to structural works in the vicinity or to watercraft, for example, are kept as low as possible. 
Danger zones shall furthermore be separated from safety zones whose function and equip 
ment are indispensable for the safe operation of the offshore station. 
Danger, protection and safety zones shall already be shown in a layout plan in the develop 
ment phase of the offshore station and shall be updated with more detail in the subsequent 
design phase. 
5.2 Development phase 
5.2.1 Preliminary remarks 
The starting point is a functional description of the offshore station whose purpose is to 
present the safety of all persons and the environment in a way that can be substantiated and 
verified. This covers all operating phases and states as well as emergency situations. The 
functional description is the fundamental requirement for the design of the offshore structure, 
where requirements from occupational health and safety shall be iteratively taken into account 
in the design as the planning progresses, and expressed in more concrete terms by means of 
detailed concepts which shall submitted to the appointed inspector for inspection. 
As early as the development phase, the design should be based on a full safety assessment tai 
lored to the whole structure in accordance with the requirements of occupational health and safety. 
It is a good idea to give consideration to these functional and technical requirements at an early 
stage of the development process, since their final design has to be included during the design 
phase of the topside at the latest. According to chapter 5.2.4, only the verification report of the ap 
pointed inspector for this study has to be submitted to BSH at the time of the development phase. 
The following aspects concerning the implementation of their design in the functional description 
and individual concepts, if applicable, serve here as topical proposals intended to describe the 
planned modes of operation of the operational structure (topside) in a comprehensible way: 
• Operational concept (incl. transport, installation, commissioning, maintenance, shut-down 
and decommissioning): 
- Operating situations, such as normal operation including winter operation, operation 
when malfunctions occur, or emergency operation 
- Transport and installation states 
- Operating modes, such as manning, mother-daughter concept 
- Interior spaces (e.g. technical services zones, sleeping accommodation, offices, commu 
nal spaces, first aid room, workshops, stores, control and communication rooms) 
- Operational or weather-related limitations, such as safe accessibility of parts of the instal 
lation, for example 
• Behaviour of the structure should a ship collide with it 
• Subdivision into protection and danger zones (explosion zones, high-voltage areas and 
others) in accordance with the occupational health and safety requirements and the design 
requirements resulting therefrom 
• Design concepts for the different fire scenarios from the aspect of fire and explosion protec 
tion (transformer, living accommodation, workshops, store, tanks etc.): 
- Illustration of fire compartments 
- Fire detection system (fire detection on decks and in rooms, for example) 
- Fire protection (passive (e.g. thicker walls) and active (stationary and mobile fire-fighting 
systems))
