Part B - Certificates and approval requirements 
21 
• Exceeding manufacturing tolerances 
• Deviations in piling depths 
• etc. 
3.2.4.7.3 Certificates for special forms of foundation 
• For special forms (e.g. suction anchors, bucket foundations, etc.), certificates shall be obtained in a 
similar way to the specified certificates for pile and gravity foundations, in consultation with the BSH. 
The BSH may engage the services of suitable assessors in this case. 
3.3 Certificate of conformity for evaluating the s i t e - s p e c i f i c 
configuration of offshore wind turbines 
Upon presentation of the reports on site conditions, load assumptions and support structure, the certifi 
cate of conformity for the offshore wind turbines is normally issued by the certifier/registered inspector. 
The certificate of conformity is issued upon the completion of the design test. 
Preconditions for issue of the certificate of conformity are that the turbine (management and safety 
system, machine, rotor, electrical engineering) are unchanged compared to the already type-certified 
offshore wind turbine, that the site-specific loads for the machine do not exceed the permitted loads in 
the type certification and that marine ambient conditions have already been taken into account in the 
type certification (climate control, corrosion protection, etc.). 
If the site-specific loads are greater than those in the type certification, the load capacity of the com 
ponents of the offshore wind turbine affected can be demonstrated by stress reserve considerations. If 
this proves unsuccessful, an adapted design of the components in question is required. The certifier/ 
registered inspector checks the stress reserve considerations and conducts parallel calculations on 
submission of new evidence. 
Additional components or tests, e.g. on-board crane or add-on and built-in components can be included 
in the design test. This shall be coordinated with the client and the approval authorities at an early stage 
(see 3.2). 
3.4 Submarine cables 
3.4.1 General 
Cables and their accessories are to be used in accordance with the state of the art, the requirements of 
the relevant standards (selection see 3.4.2) or which have their suitability demonstrated by comparable 
tests and are appropriate for the particular application conditions/situations. 
3.4.2 Technical codes of practice 
3.4.2.1 Cabling within the wind farm 
The following technical codes of practice in their current version are to be observed for test requirements 
and suitability certificates, with alternating current transmission using plastic-insulated power cables 
(energy distribution cables): 
1231 DIN VDE 0276-620 or 
1241 I EC 60502-2
