Abstract
It is disclosed a system (1) and a method for hook-up and tensioning of a floating wind turbine to the seabed. The floating wind turbine comprising at least one mooring line (3) adapted for mooring the floating wind turbine to the seabed. An installation vessel is provided with a dynamic positioning (DP) system and a winch (6), wherein the winch (6) is adapted for controlling a mooring line (3)/installation line (18). A tensioner is adapted for the mooring line/installation line. Controlling at least one of the winch and the dynamic positioning system on the installation vessel based on at least one input parameter for hook-up and tensioning of the at least one mooring line of the floating wind turbine to the seabed.
Claims24
A system for hook-up and tensioning of a floating installation to the seabed, the system comprising:
- a floating installation comprising at least one mooring line adapted for mooring the floating wind turbine to the seabed;
- an installation vessel comprising a dynamic positioning (DP) system and a winch,
- wherein the winch is adapted for controlling a mooring line/installation line;
- and
- a tensioner adapted for the mooring line/installation line;
- wherein the system being adapted for controlling at least one of the winch and the dynamic positioning system on the installation vessel based on at least one input parameter for hook-up and tensioning of the at least one mooring line of the floating installation to the seabed;
- and
- a hook-up and tensioning module for controlling a hook-up and tensioning operation for mooring of the floating installation by the installation vessel by use of the tensioner, the module comprising an interface configured to receive data from the dynamic positioning system and the winch on the installation vessel, and a control system configured to adjust the operation of the winch and the dynamic positioning system based on the received data.
