Abstract
In order to allow for a safe and cost-efficient lifting of components (1) from a service vessel (2) to a location on an off-shore wind turbine generator (3) or lowering of components from a location on an off-shore wind turbine generator to a service vessel a method involving the use of a handshake-tool (10) is provided my means of which the component to be lifted or lowered can easily be transferred from one crane to another.
Claims15
A method for lifting components from a location on a service vessel to a location on an off-shore wind turbine generator and/or for lowering components from a location on the off-shore wind turbine generator to a location on the service vessel, the method making use of at least a service vessel bound lifting apparatus and a wind turbine generator bound lifting apparatus and including a transfer step during which the component is detached from the one of the lifting apparatuses being a primary lifting apparatus and is attached the other one of the lifting apparatuses being a secondary lifting apparatus, the method including the steps of
- attaching the component to a rigging of the primary lifting apparatus and lifting or lowering the component into a transfer position in which the component can be reached by a rigging of the secondary lifting apparatus,
- performing the transfer step, wherein the component is attached to the rigging of the primary lifting apparatus via a handshake-tool and in that the transfer step is performed by attaching the component to the rigging of the secondary lifting apparatus via the handshake-tool prior to the component being detached from the primary lifting apparatus.
