A hoisting crane or multi configurations crane system for use on an offshore vessel, such a vessel and methods for operating are disclosed. The hoisting crane comprises a boom having a proximal portion, an intermediate portion and a distal portion. An extension mechanism is provided that is configured to allow the distal portion to he slid relative to the intermediate portion from a retracted configuration to an extended configuration. In the retracted configuration, the intermediate portion is arranged substantially within the distal portion.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames arc spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.

A suction anchor system comprises a substantially tubular suction anchor embeddable in a seabed, a predetermined set of sliding rails, an excavator, and a predetermined set of non-triangular wings disposed about the outer surface of the tubular, and a deployment interface which comprises a deployment cage, a suction anchor lid, and a predetermined set of deployment cage skidding rails disposed about an outer portion of the deployment cage. Using a surface vessel comprising a dispatcher which comprises a storage magazine configured to selectively receive and discharge the suction anchor, a skidding system, and an overhead anchor handler, the suction anchor can be operatively connected and secured to, and placed into fluid communication with, the deployment interface. The deployment interface along its connected suction anchor is lowed from the surface vessel into sea water using the dispatcher until the suction anchor contacts the seabed and allowed to self-penetrate below the seabed due to its own weight.

Disclosed is a method and apparatus for transferring a plurality of cargo units, each cargo unit having a cavity therein, providing a lifter suspended in free floating form by a crane, the lifter having a frame and at least one lifting arm which is detachably connected to the frame wherein the frame has at least one lifting connector for detachably connecting the lifter to the crane; moving the lifter to a position immediately adjacent the plurality of cargo units; causing each free end of the at least one lifting arm to penetrate at least one cavity of one of the plurality of cargo units; raising the at least one of the plurality of cargo units to an elevated position; moving the lifter and the at least one raised cargo unit to a second position laterally spaced from the original position wherein each free end of the at least one lifting arm is elevated compared to each second end of the at least one lifting arm; and depositing the raised cargo unit at the second position.

This invention relates generally to geotechnical rig systems and methods. In one embodiment, a cone penetration testing system includes, but is not limited to, a frame; at least one rotatable reel; at least one movable roller; and at least one sensor, wherein the at least one movable roller is configured to adjust a bend radius of at least one tube coiled about the at least one rotatable reel based at least partly on data received from the at least one sensor.

An offshore transfer system includes an arm construction with a primary measurement system to measure and compensate for relative movement of an element relative to an external reference when the element is supported by the arm tip, as well as a secondary measurement system to measure and compensate for relative movement of the arm tip relative to the element when the element is put down and no longer supported by the arm tip.

The invention provides a method for handling a blade (11) for a horizontal axis wind turbine (1), the blade extending longitudinally between a blade root (111) and a blade tip (112), the method comprising—supporting the blade (11) with one or more cranes (3), moving, by means of the one or more cranes (3), the supported blade (11) so as to be placed on one or more first support elements (4111) of a first support device (411) and on one or more second support elements (4121) of a second support device (412), removing the support of the one or more cranes (3), so as for the blade (11) to be supported by the one or more first support elements (4111) and the one or more second support elements (4121) on which the blade is placed, the second support device (412) being located between the blade root (111) and the blade tip (112), and the first support device (411) being, compared to the second support device, located closer to the blade root, moving the first and second support devices (411, 412) so as to move the blade (11) supported by the first and second support elements (4111, 4121), and/or moving a third support device (413), so that the third support device (413) assumes a support position between the second support device (412) and the blade tip (112), and removing, while the third support device (413) is in the support position, the support of the one or more second support elements (4121) so as for the blade (11) to be supported by one or more third support elements (4131) of the third support device, and by the one or more first support elements (4111).
