Abstract: The present document describes a method of hauling an equipment unit from the water onto a carrier. The carrier comprises a hauling ramp, which is arranged for being extended from a loading area into the water. The carrier further includes a first winch, and a suspension structure arranged for being extended outside the carrier over the water and over the hauling ramp. The suspension structure comprises a second winch. The method comprising the steps of: releasing, by the equipment unit, a hauling buoy. The hauling buoy is connected to a tow line extending from the equipment unit, and to a lift line extending from a lifting point on the unit. The method comprises a further step of recovering the hauling buoy from the water, connecting the tow line to the first winch and connecting the lift line to the second winch. Then, the equipment unit is hauled by towing it onto the hauling ramp using the first winch, while simultaneously guiding the equipment unit using the second winch.
