Abstract: A system for controlling a motion compensated pile guide for a floating vessel comprises a pile guide for guiding a monopile in its longitudinal direction during driving the monopile into a seabed, an actuator for moving the pile guide in horizontal direction with respect to a vessel to which the pile guide is mounted, a control unit for controlling the actuator, which control unit is configured for compensating motion of the vessel to which the pile guide is mounted so as to maintain the horizontal position of the pile guide during driving a monopile into a seabed, a first sensor for determining an inclination angle of a monopile with respect to the vertical during driving the monopile into a seabed, and a second sensor for determining magnitude and direction of an actual force of a monopile onto the pile guide during driving the monopile into a seabed.

Abstract: A device, such as a gangway, for transferring personnel and/or goods from a surface vessel to a fixed or floating structure, e.g. an offshore structure, such as a wind turbine, or to another vessel, the device comprising first and second telescoping elements and an intermediate platform for bridging the transition between the first and second telescoping elements, which platform is movable relative to both telescoping elements.

Abstract: The invention relates to a device, such as a gangway (4), for transferring personnel and/or goods from a surface vessel (1) to a fixed or floating structure, e.g. an offshore structure, such as a wind turbine (2), or to another vessel, the device (4) comprising first and second telescoping elements (9A, 9B) and an intermediate platform (11) for bridging the transition between the first and second telescoping elements (9A, 9B), which platform (11) is movable relative to both telescoping elements (9A, 9B).

Abstract: A system to monitor and analyze a multi-strand rope includes a rope data sensor to collect data regarding the physical state of the rope; one or more usage sensors to collect data regarding the usage of the rope; a position measurement device to measure the position of the rope; and a computer system connected to the rope data sensor, the one or more usage sensors and the position measurement device to correlate the collected data and position measurement to give real-time data on the status of the rope at one or more sections.

Abstract: The invention relates to a device for transferring personnel, equipment and/or structural elements from a surface vessel to an offshore structure, such as a wind turbine, or to another vessel comprising a foundation mounted or to be mounted on a surface vessel, an arm pivotally connected to the foundation and at least one gripper connected to the free end of the arm for coupling the arm to an offshore structure. A second arm is pivotally connected to the first arm.

Abstract: A vessel for e.g. well intervention or deep sea lowering, comprises a moon pool and a hoisting arrangement for lowering and retrieving items, in particular equipment, tools, and/or supplies or modules comprising the same, through the moon pool, into respectively from the sea and onto respectively from the seabed or an installation on the seabed. The vessel further comprises one or more guides for laterally retaining items inside the moon pool, preferably at least two guides positioned on opposite sides of the moon pool.

Abstract: A device for tensioning anchor chains, in particular mooring legs of off-shore vessels and installations, comprises a frame carrying connectors for holding together lower and upper portions of the chain to be tensioned. The frame further carries a tensioning mechanism for pulling at least one portion of the chain towards the other portion of the chain while the device is submerged.

Abstract: A vessel for installing a platform on an offshore support structure comprises a floating body, a lifting device which is tiltable about a tilting axis with respect to the floating body and a tilting force member for applying a tilting force to said lifting device. The lifting device is provided with a static part that is tiltable about the tilting axis and a movable part which is movable in vertical direction with respect to the static part. The tilting force member engages a drive location at the static part.
