摘要： A method and arrangement for reducing the weight and optimizing the longitudinal strength of a water-craft (1), which is especially suitable for transportation of liquefied natural gas (LNG) or other corresponding mediums and comprises a hull (2), which has a deck (3) extending over at least the main part of the water-craft (1) and a number of substantially spherical cargo tanks (4) arranged successively in the longitudinal direction (A) of the water-craft (1) and a deckhouse (5), which extend substantially above the said deck (3). The hull (2) of the water-craft (1) is provided with a continuous protective casing structure (6) known as such and which is arranged on top of the cargo tanks (4). The said deck (3) of the water-craft is arranged on the hull (2) so that the proportion of its height measured from the bottom of the water-craft to the height of the uppermost continuous portion of the protective casing structure (6) on top of the cargo tanks (4) is at most 0,55, preferably at most 0,5. In addition said protective casing structure (6) is fixed to said deck (3) and/or other structures (7) supported to the hull (2) and is dimensioned together with the other parts of the hull (2) so that together they constitute an essential part of the overall strength of the water-craft.
