Abstract
In order to allow for a safe and cost-efficient lifting of components from a service vessel to a location on an off-shore wind turbine generator 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 is provided my means of which the component to be lifted or lowered can easily be transferred from one crane to another.
Claims17
A method for lifting a component from a location on a service vessel to a location on an off-shore wind turbine generator and/or for lowering a component from a location on the off-shore wind turbine generator to a location on the service vessel, the method comprising:
- providing a service vessel bound lifting apparatus;
- providing a wind turbine generator bound lifting apparatus, wherein one of the service vessel bound lifting apparatus or the wind turbine generator bound lifting apparatus is a primary lifting apparatus and the other of the service vessel bound lifting apparatus or the wind turbine generator bound lifting apparatus is a secondary lifting apparatus;
- attaching the component to a rigging of the primary lifting apparatus via a handshake tool;
- lifting or lowering the component into a transfer position in which the component can be reached by a rigging of the secondary lifting apparatus;
- and
- performing a transfer step, the transfer step comprising:
- attaching the component to the rigging of the secondary lifting apparatus via the handshake-tool;
- and
- subsequent to the attaching step, detaching the component from the primary lifting apparatus.
