Estimation of Ultimate Wave Height Due to Strength Criteria for Vessels During Onetime Trip

Vessels that works on shelf in constrained conditions and in shallow water very often are of restricted navigation area vessels type. Operation area and place of building for such vessels may be situated on significant distance from each other so onetime trip outside of allowable by Classification Society sailing regions. In this paper method of definition of minimum allowable value of 3% probability wave height due to overall and local strength criteria for hulls of restricted navigation area vessels (RNAV) is substantiate. This method allows to carry out onetime voyage projects for sailing outside of allowable sailing regions.
