2.1.1 WFSVs are often provided with boarding systems such as gangways or similar for the transfer of workers to the turbine foundations. It is assumed that such devices for the transfer of personnel will be provided with third party certification. For plan approval purposes, such devices will be considered in way of the deck connection and supporting structure only.
2.2.1 Rudder supporting structure may be required to be additionally strengthened to allow for the distribution of loads occurring from the running of the engine(s) whilst transferring workers to the turbine platforms.
2.3.1 Where the Wind Farm Service Vessel is designed to be driven against turbine foundations, for the purposes of transferring workers, the hull structure is to be suitably strengthened to withstand all anticipated operational loads.
2.4.1 Areas exposed to contact/impact loads are to be protected by a suitable fender arrangement.
2.5.1 The arrangements for container stowage and securing will need to be considered. Additional loads from containers will need to be accounted for in the calculation of deck scantlings and a deck loading plan submitted. It is assumed that WFSVs will carry small amounts of cargo, for example with limited numbers of containers with no stacking.
