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. Moving the object suspension device to a charging position thereof by employing the hoist assembly of the crane brings the input connector of the energy storage unit in close proximity of the output connector of the energy charging unit which are then interconnected to charge the energy storage unit from a separate energy source.

A clam bucket assembly comprise an assembly framework which comprises an upper section and a lower section. First and second clam buckets are supported by the lower section of the assembly framework, a first bucket cylinder controls operation of the first clam bucket to engage and discharge a desired bulk material, and a second bucket cylinder controls operation of the second clam bucket to engage and discharge a desired bulk material. The clam bucket assembly supports its own independent power module for supplying hydraulic power to at least the first and the second bucket cylinders and controlling operation of the first and the second clam buckets. The power module is supported by the upper section of the assembly framework, and the clam bucket assembly is completely powered solely by the power module and controlled by radio remote control receiver and transmitter.

Method and device (1) for lifting loads (7). An arm (2) that is the load or that supports a load (7) is pivotably connected to a reference. The load results in a torque. At least a part of the counter-torque to result in a system supporting the load is provided by a gas or hydro-pneumatic spring (60).
