Part B - Verifications and approval requirements 
If the risk assessment results in demands being placed on the design, these shall be taken 
into account. 
• Passageways, transport routes and storage areas 
Illustration and description of the different levels on the particular deck and the routes resul 
ting from this on this deck and the operational structure of the offshore station (topside), 
including the effects of their loads on the structure. 
Cat ladders and step iron ladders are special types of passageway which are permissible 
only under certain conditions. 
Suspended loads, such as material transports in shafts or material transported by crane, 
shall also be taken into account. 
The following design requirements for transport thoroughfares (pedestrian and vehicle traf 
fic), storage areas and means of transport shall be taken into account in the design: 
- Type 
- Connections 
- Layout 
- Dimensions 
- Description of the vertical and horizontal transport operations 
- Layout and type of the transport systems, lifting gear and crane systems 
- Information on the usability certificates of the transport systems, lifting gear, crane sys 
tems and the resulting additional load applied to the support structure 
- Description and illustration of the horizontal and vertical transport operations 
- Transport of heavy parts over machines and/or installations which are in operation 
- Repositioning of the helicopter using a crane (where necessary). 
• The impact of the bunker stations on the design due to their dimensions and dead-weights 
shall be taken into account. 
5.3.1.2 Fire and explosion protection concept 
As early as the design phase, a fire and explosion protection concept shall be drawn up in ac 
cordance with the protection objectives to be laid down in the development phase; the con 
cept deals with the applicable hazards and shall be updated during the course of the project 
when structural or technical changes are made. This fire and explosion protection concept 
could lead to design specifications, such as the use of fire partitions or fire-protection upgrad 
ing of support structures. 
The fire and explosion protection concept shall contain at least the following requirements: 
• Description of the operational structure of the offshore station (topside), incl. its load-bea 
ring components, partitioning components and local situation regarding fire protection and 
the design details resulting from this 
• Type of offshore station utilisation (long-term utilisation plan) 
• Maximum number of persons working on the offshore station 
• Fire load of the usable and storage areas 
• Representation of the protection objectives and, in particular, a description of the important 
points of the protection objectives in relation to personal and environmental protection
