and certified companies. Cranes, lifting gear and tackle, including all cables, hooks, etc. shall be main 
tained in accordance with the regulations for safe handling. Approval by the BSH is required before 
equipment, processes or materials can be used that do not correspond to a recognised standard. In 
this case, the BSH may call on the services of appropriate assessors for assessing the procedures. The 
installation processes shall be selected so the work can be interrupted when necessary without endan 
gering personnel or the equipment. Personnel are to be provided with personal protective equipment in 
accordance with the regula-tions, and which shall be worn accordingly during the work. 
The installers and entities involved in the installation shall draw up an installation manual. The objec 
tive of this installation manual is to provide a clear presentation of procedures together with the general 
technical conditions. The presentation should describe the phases with sufficient detail so as to enable 
feasibility and logistics to be checked. The installation manual shall be updated and includes the follow 
ing phases, amongst others: 
• Implementation 
• Operation 
• Decommissioning 
Special general conditions during installation work are documented in the installation manual. These 
include, amongst other items, unusual external conditions such as a heavy swell, strong winds, extreme 
times, ice drift, hail, lightning, earthquake. 
If a helicopter link is required for connecting the construction site to the mainland, landing platforms shall 
be provided for this with regard to the distance from the mainland, fire protection, marking, etc. and in 
accordance with the relevant national and international regulations. 
4.2 Technical codes of practice 
In all cases, the following technical codes of practice are to be applied, amongst others, in their relevant 
current versions as well as the generally accepted state of the art: 
f461 prEN ISO/19901-6, after implementation, 
f471 DNV Marine Operations 
f481 GL Rules and Guidelines IV 
15] API RR 2A-LRFD 
f61 GL Guideline for the Certification of Offshore Wind Turbines 
4.3 Approvals from the responsible authorities 
The required consultations shall be undertaken with the relevant authorities for all steps in implementa 
tion, operation and decommissioning or - as necessary - presented for approval. 
4.4 Required certificates for the implementation phase 
Detailed implementation planning is to be drawn up. Checklists and operation manuals for all planned 
activities shall be prepared and updated. Records shall be kept of the implementation (diary). The speci 
fied documents shall be permanently available at suitable locations (at least one at the site management 
offshore and another at the land base) where they can be viewed. The situation report shall be prepared 
after completion of the work and documents the actual situation on the soil. These documents form part 
of the installation manual.
