The present invention provides a method to hand over a load, in particular when submerged, from a first hoisting device to a second hoisting device, comprising the steps of: providing a rigid intermediate device having a first connection point and a second connection point, wherein the first connection point and the second connection point are spaced with respect to each other with a distance of at least 5 meters, and wherein the intermediate device is configured to be connected to the load, connecting the load to the intermediate device, connecting the first hoisting device to the first connection point, suspending the load completely from the first hoisting device, connecting the second hoisting device to the second connection point, and&#x2014;transferring the load from the first hoisting device to the second hoisting device, until the load is completely suspended from the second hoisting device.
