Part B - Verifications and approval requirements 
21 
(7) Test and evaluation of sea operations and the decommissioning concept, 
(8) Production and installation monitoring, 
(9) Inspection of loading and transport from the quayside to the installation site, installation 
and commissioning, 
(10) Certificate of conformity and verification report for the monitoring services following 
completion of items (6) to (9), 
(11) Project certification in accordance with this standard, 
(12) Periodic inspections in order to maintain the operating permit and 
(13) Inspection and monitoring of the decommissioning phase and issue of the respective 
certificate of conformity, resp. test certificate. 
It is highly recommended to engage an appointed inspector - and to exchange information 
with this inspector - at an early stage so as to be able to coordinate the design basis (deter 
mining the site conditions, incl. the subsoil situation and which regulations and methods apply 
to the design basis) with this appointed inspector as early as possible. 
1.2 Language 
The official language is German. All documents which are or shall be deemed binding during 
the approval process before the approval authority, must be submitted in the German lan 
guage. This shall apply, in particular, to all reports and documents compiled by the appointed 
inspector (verification reports, monitoring reports, certificates of conformity, etc.). 
As a rule, technical documentation may be submitted in English. 
1.3 Timescale 
1.3.1 Preliminary remarks 
The timescale for realising an offshore structure project can generally be divided into the fol 
lowing phases (project phases): 
• Development 
• Design 
• Implementation 
• Operation and 
• Decommissioning. 
Table 1 -1 summarises the timescale for offshore wind turbines. Each phase includes a definition 
of the overriding objectives to be achieved by the end of each respective phase. The first two 
phases (Development and Design) differentiate between three different types of document: 
Basic documents: Documents which contain information on the conditions established and 
measured at the site. 
Design rules: Regulations, standards, guidelines and approaches that define how the site 
conditions are to be applied - including dimensioning and design - from an 
engineering perspective. These represent the design basis for the respective 
offshore structures. 
Planning results: Computed results and verifications, drawings, specifications and implemen 
tation notes based on the design rules and basic documents.
