first wind turbine or offshore station. This document shall contain a descrip 
tion of at least the following points in a plausible and transparent manner: 
- Planned inspection intervals and the respective explanatory statement 
- Identification of the parts subject to wear, in particular the parts that are 
subject to special demands and stress due to marine influences (e. g. cor 
rosion and marine growth) 
- Determining of the scope of the inspections and the inspection intervals 
depending on the durability and environmental compatibility of the respec 
tive corrosion protection system, as well as 
- Monitoring of the scouring protection system.

2.5 Operating phase 
2.5.1 Preliminary remarks 
Operations shall begin on the date of issue of the operating release by the BSH; this presup 
poses that the incidental provisions of the notice of approval have been accordingly fulfilled 
and likewise presumes that all stipulations made at the various approval stages have been 
fulfilled during the preceding phases. On a case-by-case basis, non-significant tasks that re 
main to be completed may be carried out during the operating phase if so agreed with the 
approval authority. This shall be noted in the operating release document. The operating re 
lease is based on establishing that the structures have been installed correctly. 
During the operating phase, a status meeting between the approval holder and the approval 
authority shall be held once a year in order to discuss the condition of the offshore wind farm. 
To this purpose, the approval holder shall compile a detailed and informative status report on 
the condition of the offshore structures. This shall be submitted to the approval authority at 
least six weeks prior to the scheduled meeting, together with the summary verification report 
compiled by the appointed inspector, as well as the certificate of conformity pertaining to the 
test and inspection plan for periodic inspections (please refer to chapter B1.3.5). 
In the case of changes to the morphological structure of the terrain in question (e. g. scouring) 
in excess of that provided for in the provisions upon which the structure is based, a new state 
ment on the stability shall be drawn up, whereby a geotechnical planning expert shall be ac 
cordingly involved. 
In the case of major repair work or component replacement, the procedure to be followed 
shall be based on the conditions for installing the structure; the appointed inspector shall be 
accordingly involved in this process. This process is completed by the submission of a re 
spective report to the BSH by the approval holder. 
The operating release marks the commencement of normal operations following the installa 
tion of the structure. 
2.5.2 Technical codes of practice 
The following technical codes of practice, among others, in their respective current version, as 
well as the current state of the art, shall apply analogous to the installation procedure:
