namely „Standard for Geotechnical Site and Route Surveys. Minimum Requirements for the Foundation 
of Offshore Wind Turbines and Power Cable Route Burial Assessments“ JTj in the current version in each 
case; any deviations shall be applied for to the approval authority and their equivalence shall be justified. 
The offshore wind turbine including the structures used for its foundation and the transformer substation 
as well as cabling within the farm shall be inspected by an expert institution, person or group of persons 
(certifier/registered inspector) recognised by the BSH on a case-by-case basis. The inspection shall be 
completed with a confirmation to be presented to the BSH. The confirmation shall contain an expert's 
declaration that the overall project, a technical system or a component of such has been configured in 
accordance with the generally recognised rules of technology or, failing that, the current state of scien 
tific progress. 
The owner, companies undertaking the construction and installation work as well as authorised certifiers/ 
registered inspectors shall take suitable organisational measures to ensure that the BSH is continuously 
involved in the inspection process. A project plan including a chart of the milestones and suitable organi 
sational steps for further implementation shall be presented. Construction and/or operating permits may 
be suspended if information or certificates are not presented in accordance with the regulations of the 
approval authority. 
The necessary certificates shall be presented phase-by-phase in accordance with the progress of the 
project fsee Table 2. page 37). 
Planning checked by the certifier/registered inspector including a draft of the system structure (provi 
sional design basis and preliminary draft) shall be presented to the BSH for examination and approval. 
The design basis and the preliminary draft based on it are regular components of the application docu 
ments and, at the same time, form the basis for the environmental impact study as well as for the call 
for tenders. It shall contain at least the technically feasible variants of the design components that are 
possible at the site in question, based on qualified investigations and expert opinions. 
During the course of the design phase, the design basis and the tested basic design that are updated 
based on the results of the call for tenders and/or specification of the individual design components shall 
be presented to the BSH for examination and approval in good time, however at least one year before 
installation of the systems. These shall contain the documents that are usual for the structures (construc 
tion and design drawings, construction phase plan, etc.). At this point, binding data shall be presented for 
the further cornerstones and milestones in the schedule for the implementation phase. 
Following completion of the design phase, the inspected implementation planning is to be presented to 
the BSH for examination and approval. 
Justification: 
Compliance with the conditions to maintain the quality standard of the state of the art as well as 
certification of the systems and components guarantees structural safety of the system. The de 
sign and equipment variant that the approval holder intends to install, but which cannot however 
be determined at this phase, will then be checked by a third expert body to ensure that the normal 
quality requirements are satisfied. In this way, it will be possible to ensure that the current approval 
can be effectively issued without detailed construction and design drawings being available. These 
documents and certificates shall be presented within the named appropriate period in order to 
allow them to be checked before the systems are installed. Earlier presentation of the documents 
is not only possible but also desirable in order for additional changes to be made if necessary. The 
standard site survey JTj contains minimum requirements that include in particular specifications 
for the geological, geophysical and geotechnical site survey. The standard is currently at the sta 
tus of 1 August 2003 and is being updated. The current version shall be used in each case. The 
approval authority shall decide on deviations on a case-by-case basis, and exclusively reserves 
the right to commission a test report from a classification society (§ 5 para. 2 SeeAnlV) or other 
suitable experts at the expense of the applicant.
