Dredging International N.v.

High Wind N.v.

Etienne Clymans

A device for placing a rotor blade of a wind turbine. The device includes a hoisting means on a surface of which a boom rotatable around a substantially vertical rotation axis is provided with at least one hoisting cable. The at least one hoisting cable includes an attaching means, to which a rotor blade for placing can be attached via an elongate hoisting yoke, the hoisting yoke extending in a longitudinal direction of the rotor blade. The boom includes a guide device to limit movement of the hoisting yoke in a direction running transversely of the lifting plane. The device or hoisting yoke further includes a displacer for displacing the hoisting yoke or parts of the hoisting yoke in the longitudinal direction of the rotor blade. A method which makes use of the invented device.

Device and method for placing a rotor blade of a wind turbine

The invention relates to a device for assembling a structure constructed from components, in particular a wind turbine. The device includes a lift placed on a surface for the purpose of placing a component on an available support structure, wherein a boom of the lift is provided with a main hoisting cable with a hoisting tackle for releasable attachment of the component for lifting to the boom. The boom further includes a guide device for the hoisting tackle, the guide device is connected to the boom for displacement along a longitudinal axis of the boom using a displacing device, and the guide device is configured to limit movement of the hoisting tackle in at least one direction. The invention likewise relates to a method which makes use of the invented device.

Device and method for assembling a structure

A device for placing components of a structure, in particular a wind turbine includes hoisting means placed on a surface, a boom of which is provided with a hoisting cable with attaching means for a component for placing, wherein a lifting plane is defined by the boom and the free-hanging hoisting cable. The boom includes a guide device for the attaching means. The guide device is connected to the boom by means of a displacing device displaceable along a longitudinal axis of the boom. The guide device is configured to limit movement of the attaching means in a direction running transversely of the lifting plane, and further includes a catching construction configured to receive and displace the attaching means parallel to the lifting plane between a position in the vicinity of the boom and a position further removed from the boom and/or vice versa.

Device and method for placing components of a structure

In one embodiment of the present invention, an apparatus is disclosed for accommodating a substantially vertical spud of a dredging vessel with a longitudinal direction, including a spud carriage which is mounted for limited rotation around a horizontal transverse axis, wherein at least a first and a second spring device is arranged under bias between vessel and spud in the longitudinal direction for the purpose of absorbing a moment on the spud carriage, which first and second spring devices compensate each other in the non-loaded situation of the spud; and at least one spring device is provided with a spring force limiting device for limiting the tension in the spring element from a determined maximum moment on the spud carriage.

Apparatus with flexibly mounted spud carriage

A device is disclosed for changing a suction mouth of a cutter suction dredge of a vessel with cutter ladder. In at least one embodiment, the device includes, comprising a work platform which, as seen in the transverse direction of the vessel, is provided substantially in the middle with an opening, wherein&#x2014;a support structure is provided which can be fixedly connected to the work platform in a position substantially under the opening, which support structure is adapted to support a suction mouth;&#x2014;and the work platform with support structure is tiltable around a first, substantially horizontal transverse axis between a substantially horizontal operating position and a high position in which the cutter ladder can be moved upward, which positions are such that the work platform with support structure is movable from its high position to its operating position when the cutter ladder is situated in a high raised position.

Device and method for changing a suction mouth

Device for dislodging and recovering dredging material of varying nature, comprising a bearing housing (), a drive shaft () mounted therein for rotatingly driving with a determined torque a cutter head (') with a support ring (&#x2032;), which cutter head is mountable on the drive shaft via a hub (), and a suction pipe () which can be connected to a suction mouth (&#x2032;) which is surrounded by a fixed cutter shield (&#x2032;) which fills the space between the rotating support ring on the one side and the suction mouth and the bearing housing on the other, wherein a number of cutter heads with a different support ring diameter can be mounted on the drive shaft, wherein the support ring diameter is determined by the torque and the nature of the dredging material to be recovered.
