Abstract : Various aspects of capability and demand of ships such as extreme loads, cyclic loads, plastic design, crack design, collapse and damage are discussed in an attempt to make a synthesis. It is explained that whenever permissible stresses are used in structural design, they should be bounded by probability-concepts, deformation criteria and critical crack lengths. For an acceptable risk factor, the margin between capability and demand seems to be substantial in ships. Yet drastic reductions in structural weight will only be possible if the principle of 'fail safe' design is adopted in shipbuilding to the same extent as in aeroplane-building.
