A convertible pump formed of wound flexible tubing having an inlet communicating water to an outlet at an opposite end of the tubing. A paddle wheel with collapsible fins provides power to rotate the pump when in a vertical position. A planar surface of the wound tubing forms a table when pivoted on a stand to a horizontal disposition with the support surface for the stand.

An anchoring and lifting system for a wind turbine tower having a tower base; a plurality of base anchors attached to the tower base; an anchor outrigger attached to and extending laterally outward from the tower base; at least one secondary anchor attached to the anchor outrigger; a lifting outrigger attached to a hinge wherein the hinge connects the tower base and a tower for moving the tower between a raised position and a lowered position; a static cable connected between a distal end of the lifting outrigger and a hub attached to the tower; and, a lifting cable attached between the distal end of the lifting outrigger and a winch, wherein the winch is carried by the tower base.

Systems and methods for loading a cargo aircraft are described. The system includes at least one rail disposed in an interior cargo bay of a cargo aircraft that extends at an angle relative to an interior bottom contact surface of a forward portion of the interior cargo bay, through a kinked portion and an aft portion of the interior cargo bay. Payload-receiving fixtures are described that can be used in conjunction with the rail system, allowing for large cargo, such as wind turbine blades, to be transported by aircraft. Methods of loading a cargo aircraft can include advancing the large payload into the interior cargo bay of the aircraft such that at least one of the payload-receiving fixtures rises relative to a plane defined by the interior bottom contact surface of the forward portion of the interior cargo bay. Various systems, methods, components, and related tooling are also provided.

The offshore jack-up has a hull and a plurality of moveable legs engageable with the seafloor. The offshore jack-up is arranged to move the legs with respect to the hull to position the hull out of the water. The method comprises moving at least a portion of a vessel underneath the hull of the offshore jack-up or within a cut-out of the hull when the hull is positioned out of the water and the legs engage the seafloor. A stabilizing mechanism mounted on the jack-up is engaged against the vessel. The stabilizing mechanism is pushed down on the vessel to increase the buoyant force acting on the vessel.

A method of optimizing a packaging of large irregular objects is disclosed. The method includes receiving a first 3D object and a second 3D object, calculating, for an orientation of the first object and the second object, a minimum clearance between the objects, the orientation of the objects including a plurality of degrees of freedom, storing the orientation of the second object and calculated minimum clearance as a payload orientation, and adjusting each degree of freedom of the second object through a series of nested loops. Each loop of the nested loops increments a degree of freedom and, for each increment, repeats the calculating, storing for a corresponding orientation of the second object. The method can include receiving a constraint and, for each increment, comparing the calculated clearance to the constraint and storing the orientation of the second object only if the calculated clearance satisfies the constraint.

Provided is a method for manufacturing a wind turbine, the wind turbine including a high voltage cable configured to connect a generator of the wind turbine with a switch gear of the wind turbine, the method: a) guiding the high voltage cable inside a tower of the wind turbine from an upper part of the tower to a lower part of the tower, and b) returning the high voltage cable at the lower part of the tower up again. Returning the high voltage cable at the lower part of the tower up again simplifies storing an additional length of the high voltage cable inside the tower.

The present invention relates to a wind turbine rotor blade spacer, a transportation and storage system for wind turbine rotor blades and a related method that prevent the vertical flexion of each one of the blades assemblies, minimizing the stresses and avoiding the contact between vertically and/or horizontally adjacent blades, and in consequence, blade damage. Also, the overall occupied surface by the system once assembled is minimised.

The present invention relates to a method of performing at least one post-moulding operation on a blade segment (70) of a wind turbine blade. The method comprises the providing a holding device (88) for supporting the blade segment (70) at its spar structure (62), the holding device (88) comprising a coupling member (90) for engaging the spar structure (62). The blade segment (70) is held with the holding device (88) such that the spar structure (62) of the blade segment (70) is engaged by the coupling member (90), and performing at least one post-moulding operation on the shell structure (82) of the blade segment (70).

The present disclosure relates to a root portion for a wind turbine blade. The root portion comprises a coupling flange, configured for coupling the root portion to a hub of a wind turbine. The root portion further comprises at least one support element fixedly attached to the coupling flange. At least one support element defines a support plane for contacting a transport and/or storing surface. The present disclosure also relates to a wind turbine blades comprising such a root portion and to methods for positioning the wind turbine blade.

A method for transporting a tower section of a wind turbine, comprising the steps of: providing a tower section which is adapted to be transported in a predetermined transport position, wherein the tower section when in the transport position has a longitudinal axis extending in the horizontal direction and a wall extending along the longitudinal axis, wherein the tower section is adapted to adopt a first vertical height when in an unstressed state in the transport position, applying a deformation force to the wall so as to elastically deform at least one portion of the tower section in such a way that the tower section adopts a second vertical height that is smaller than the first vertical height when in an elastically deformed state in the transport position, and locking the tower section in the elastically deformed state.
