Method for positioning a digging tool (7;29;47) relative to a vessel comprising a hull (2), the digging tool (7;29;47) being situated at one end of an elongated element (4,6;24-26;46) connected to the hull (2;22;42) by a hinge coupling (3;23;43) and comprising, between the digging tool and the hinge coupling, at least one hinge connection (5;27,28;45), which divides the elongated element into two parts which are pivotable relative to each other and enclose an angle relative to each other, while starting from a situation in which vessel and digging tool (7;29;47) move at the same speed, an externally caused change of the speed of displacement of the vessel involves active control of the hinge connection (5;27,28;45) to move through swiveling such that the speed of the digging tool in direction of travel remains unchanged relative to said starting situation. A vessel for performing such method. <IMAGE> |
