Part B - Certificates and approval requirements 
The basic precondition for rapid and safe laying of submarine cables is a detailed survey of the planned 
cable route with regard to the soil properties of the seabed, meteorological and oceanographical condi 
tions in the sea area as well as existing uses along the cable route. 
In this regard, reference is made to the current versions of the following technical codes of practice: 
f11 Standard for Geotechnical Site and Route Surveys, in particular section B.6 and 
f451 ICPC recommendations, in particular no. 9 
In addition, the following shall be observed: 
• The suitable laying process shall be defined in good time on the basis of the aforementioned soil 
survey: 
Simultaneous lay & burial (SL & B), i.e. laying and trenching in one working step and/or 
Post lay burial (PLB), i.e. the cable layer and trencher operate at different times. 
• Knowledge of the availability of special equipment is obtained in good time in order to guarantee 
reliable planning and, consequently, the shortest possible construction times 
• Avoidance of cable joints wherever possible. In any event, joints are to be installed with an adequate 
distance from shipping lanes. 
3.4.5 Cable protection 
With regard to the protection of the cable and consequently the associated avoidance of cable repairs 
and construction sites, care shall be taken that the cables: 
• are kept away from shipping lanes if possible 
• cross shipping lanes with the shortest possible distance with regard to existing offshore installations 
(e.g. pipelines) 
• shall be installed as deep as possible in the seabed with regard to environmental effects 
• shall have their route length optimised in order to achieve the shortest possible installation length 
and therefore a short construction phase 
• provided with additional mechanical protection where necessary, e.g. in the case of intersections 
with other existing cables 
• have sufficient armouring 
3.5 Additional components of the offshore wind farm 
Other central components of the wind park are: 
• Wind measuring mast 
• Transformer substation 
• Service and accommodation platforms 
• Lifting gear, cranes and add-on components 
The aforementioned procedure for project certification/testing shall be applied accordingly for this pur 
pose. Certification can take place on the basis of GL guidelines for offshore structures, DNV standards 
or other directives (see Appendix 21. 
4 Configuration, operation and decommissioning 
4.1 General 
All of the equipment used for offshore work shall comply with the regulations and standards of Ger 
man and European standards with regard to safety, environmental compatibility and load capacity.. The 
equipment shall be in good condition at all times. Repairs are only allowed to be performed by suitable
