Abstract
Provided is a construction apparatus for safe and smooth construction of a floating offshore wind turbine generator in deep sea. The construction apparatus for constructing the offshore wind turbine generator with a crane ship includes a guide member attached to the crane ship in a work position perpendicular thereto such that a bottom end of the guide member is disposed under the sea and at least one pair of arm units that include grippers capable of holding and releasing a tower member divided into a plurality of segments in an axial direction and that slide along the guide member.
Claims16
A construction apparatus for constructing a floating offshore wind turbine generator having a tower member with a crane ship, the apparatus comprising:
- a guide member having an axial direction and configured to be attached to the crane ship in a work position perpendicular thereto such that a bottom end of the guide member is disposed under the sea;
- and
- at least one pair of arm units attached to the guide member and each of said arm units including a plurality of sets of grippers whose distance from each other in the axial direction is changeable,
- wherein said plurality of sets of grippers are slidable along the axial direction of the guide member for holding and releasing a tower member divided into a plurality of segments in the axial direction.
Maintenance equipment for maintaining a floating offshore wind turbine generator having a tower member with a crane ship, the equipment comprising:
- a guide member having an axial direction and configured to be attached to the crane ship in a work position perpendicular thereto such that a bottom end of the guide member is disposed under the sea;
- and
- at least one pair of arm units attached to the guide member and each of said arm units including a plurality of sets of grippers whose distance from each other in the axial direction is changeable,
- wherein said plurality of sets of grippers are slidable along the axial direction of the guide member for holding and releasing a tower member divided into a plurality of segments in the axial direction.
