A loading device for marine transfer of fluids, via a flexible loading hose, from a petroleum production platform to an ordinary tanker vessel has a main hull which includes a submerged hull and a structure resting on the submerged hull an rising above the waterline. A loading hose is arranged in a crane boom and is connected upstream to the flexible hose and arranged for transferring fluid to the tanker vessel. The loading device further includes fixed contact surfaces having upwards directed surfaces on the submerged hull. The submerged hull is arranged for being ballasted and deballa ted for docking towards the bottom of the tanker vessel's hull, using direct contact friction. A power device is arranged for moving the loading device into and out of a catching position with the tanker vessel, and is arranged for controlling the position of the tanker vessel during the operation of fluid transfer.
