Key facts
A davit crane is a crane, which can lift loads from a workboat and slew them around to lower them onto the main work platform. They have become almost universally adopted on offshore wind turbines to lift tools, auxiliary generators and smaller spare parts of up to approximately one t.
They are particularly useful when a small CTV is used to access the wind turbine, as these vessels do not have a crane capable of lifting onto the main external work deck.
Tools and parts can also be moved onto offshore turbines using a motion compensated gangway, vessel crane or helicopter.
