Part B - Verifications and approval requirements 
• Description and illustration of lightning and overvoltage protection installations and the de 
sign standard according to which the system shall be planned and installed 
• Description and illustration of special protection installations, such as those for hazardous 
materials 
• Information and illustration of pressure generation systems (overpressure as well as nega 
tive pressure) 
• Information on the requirements from the evacuation plan and the escape route plans and 
the design requirements resulting from this. 
5.3.1.3 Access concept 
The offshore station shall have means of access for staff and material. The construction 
measures resulting from the access concept shall be shown in detail; they shall contain the 
information below. 
The concept shall consider the normal operation of the offshore station. 
The following aspects at least shall be taken into account in sufficient detail: 
• Definition of the field of application 
- Normal operation after erection, incl. maintenance, repair, standstill 
• Description of the operational structure and the support structure of the offshore station in 
relation to its utilisation (offshore converter station, substations, accommodation etc.) and 
configuration (i.e. offshore station complex or individual structure) 
• Site description, incl. 
- Environmental conditions to be expected (statistical annual view) and alignment with 
operational requirements or plans concerning frequency of use 
• Planned number of persons or utilisation of the access systems (transport of persons, 
transport within the wind farm, normal operation or emergency) 
• Planned means of access (helicopter landing pad, area with winch operation, static or ac 
tive boat landing systems, crane systems). At least two independent means of access to 
the offshore station shall be provided. 
• Restrictions on access: 
- Structural restrictions (e. g. loads, dimensions) 
- Weather conditions 
- Amount of swell 
- Tidal water levels 
- Wind speeds 
- Visibility conditions, incl. times of day 
• Construction or structural requirements placed on access systems 
• Requirements placed on means of transport (ship, helicopter, crane) 
• Interfaces to other concepts (e. g. evacuation, operation). 
5.3.1.4 Space utilisation plan 
A plan for the utilisation of the spaces on the different decks shall be drawn up and shall state 
the distributed loads (e.g. position, dimensions and weight of the loads).
