  • Patent number: 11939191
    Abstract: A system includes a crane and an exchangeable tool. The crane and the tool respectively, include an upper tool connector with tool retainers and a lower tool connector which can be interconnected, e.g. a male and female connector, e.g. the lower tool connector of the tool being embodied as a shank provided with a shoulder and the upper tool connector as a tool clamp with a female, open-centered body. A tool suspension device includes the upper tool connector and a travelling block member. The tool clamp has multiple mobile tool retainers adapted to—in a non-operative position—allow introduction of the shank of the tool from below into the shank receiving passage and—in an operative position—engage below the shoulder of the shank that has been introduced into the passage so as to suspend the tool. The upper tool connector may include a bearing allowing for swivelling of the open-centered body, and e.g.

  • Patent number: 11939193
    Abstract: Providing energy to an energy consuming piece of equipment and/or tool during offshore operations. Use is made of a crane including a substructure, a boom mounted on the substructure, one or more hoist winches and cables, as well as an object suspension device suspended from the boom by the cables. A piece of equipment or tool is suspended from the object suspension device. An energy storage unit is provided on the object suspension device and has an input connector. The boom may be provided with an output connector of an energy charging unit and in a lower supply position of the object suspension device it is disconnected from the input connector of the energy storage unit. The piece of equipment or tool is then run on energy supplied by the energy storage unit.

  • Patent number: 11008726
    Abstract: A method for installation of a pile adapted to support an offshore wind turbine in which the piles are transported horizontally, positioned in a pile holder, rotated to a vertical orientation while being held by the pile holder, and subsequently lowered into the water while being held by the pile holder. The installation vessel is in a floating condition, and the pile holder is compensated for wave-induced motion of the vessel to maintain a predetermined X-Y location independent of the wave-induced motion of the vessel. A pile holding system, a pile holder, and a vessel comprising a pile holding system are also disclosed.
