The present invention generally relates to a system, device and a method for loading and/or unloading a cargo to and/or from a second vehicle where a loading device is mounted on a first vehicle. More specifically, the present invention relates to a method and a device for a sensor system (with sensor platform deployed at the crane tip) used for heave compensation and 3D positioning of cargo and second vehicle during loading and unloading process of cargo to/from a ship where a crane is mounted on an oil rig.

A method and heave compensator for eliminating snap-load and heave effects at offshore deposition of a load into or onto the sea or seabed involves a heave compensator suspended between the load and the lifting device having a relatively stiff stroke response at small to moderate stroke lengths and then a softer stroke response at larger stroke lengths to avoid exceeding the dynamical amplification factor (DAF)-limitations of the crane/lifting device or on the load.

Various hoisting systems with heave compensation are provided. In one embodiment, an apparatus includes a hoisting system having a crown block and a drawworks. The drawworks includes a rotatable drum for reeling in and reeling out a hoisting line that is wound on the rotatable drum and reeved over the crown block. The hoisting system includes active heave control at the drawworks and a passive heave compensation system. Additional systems, devices, and methods are also disclosed.
