The shipbuilding design rules require several criteria for the assessment of any floating structure.For this technical paper, a 23000 t off-shore barge is assessed by oblique waves global strength criteria.Two barge concepts are evaluated, with the main changes of breadth and draught.

Focusing on the gemplers coupon preliminary analysis that involves the initial concepts of the off-shore barge, the oblique global strength assessment is wx gloves done by equiva-lent 1D beam structural model approach on significant design waves range.The study of the two off-shore barge concept versions points out their restrictions in operation by global strength preliminary criteria.
