An arrangement for loading individual reels (5"), such as metal reels, into a cargo vessel and shipping them in the cargo vessel, the arrangement comprising reel troughs (30") designed to keep the reels (5") to be positioned therein in place at least in the horizontal and downward directions, the reel troughs (30") being arranged on an elongated cradle frame structure (4b") that is at the bottom (12") of the vessel's cargo hold (1, 2) and transverse to the longitudinal direction of the vessel so that its longitudinal sides (18", 19") are transverse to the longitudinal direction of the vessel, the elongated cradle frame structure being uniform and formed of one cradle frame extending from a first side wall (15") of the vessel's cargo hold to a second, opposite side wall (16") of the cargo hold, characterised in that - the arrangement comprises a second elongated cradle frame structure (4b"), which comprises reel troughs (30") designed to keep individual reels (5") to be positioned therein in place at least in the horizontal and downward directions, the second cradle frame structure (4b") being positioned transverse to the longitudinal direction of the vessel above the cradle frame structure (4b") at the bottom (12") of the cargo hold (1, 2) so that its longitudinal sides (18", 19") are transverse to the longitudinal direction of the vessel, the second cradle frame structure being uniform and formed of one cradle frame extending from the first side wall (15") of the vessel's cargo hold to the second, opposite side wall (16") of the cargo hold, and the second cradle frame structure being positioned in such a manner that a bottom level (70") thereof is at most at a distance of 2 m from the top level (60") of the cradle frame structure (4b") at the bottom of the cargo hold, - the arrangement comprises several cradle frame structures (4b") that are arranged on top of each other in a tower-like manner and that each comprise crosswise, upward-opening troughs (30") designed to keep reels (5") positioned therein in place at least in the horizontal and downward directions, - each cradle frame structure (4b") further comprises crosswise, downward-opening troughs (40") to permit the reception of the top parts of the reels (5") in the cradle frame structure (4b") positioned below, and - in adjacent cradle frame structures (4b") positioned on top of each other, the vertical symmetry planes (X-X) of the downward-opening troughs (40") are in line with the symmetry planes (Y-Y) of the upward-opening reel troughs (30") of the adjacent cradle frame structure. - the arrangement comprises a second elongated cradle frame structure (4b"), which comprises reel troughs (30") designed to keep individual reels (5") to be positioned therein in place at least in the horizontal and downward directions, the second cradle frame structure (4b") being positioned transverse to the longitudinal direction of the vessel above the cradle frame structure (4b") at the bottom (12") of the cargo hold (1, 2) so that its longitudinal sides (18", 19") are transverse to the longitudinal direction of the vessel, the second cradle frame structure being uniform and formed of one cradle frame extending from the first side wall (15") of the vessel's cargo hold to the second, opposite side wall (16") of the cargo hold, and the second cradle frame structure being positioned in such a manner that a bottom level (70") thereof is at most at a distance of 2 m from the top level (60") of the cradle frame structure (4b") at the bottom of the cargo hold, - the arrangement comprises several cradle frame structures (4b") that are arranged on top of each other in a tower-like manner and that each comprise crosswise, upward-opening troughs (30") designed to keep reels (5") positioned therein in place at least in the horizontal and downward directions, - each cradle frame structure (4b") further comprises crosswise, downward-opening troughs (40") to permit the reception of the top parts of the reels (5") in the cradle frame structure (4b") positioned below, and - in adjacent cradle frame structures (4b") positioned on top of each other, the vertical symmetry planes (X-X) of the downward-opening troughs (40") are in line with the symmetry planes (Y-Y) of the upward-opening reel troughs (30") of the adjacent cradle frame structure.
