Practice-Based Operability Limiting Criteria in the Adriatic Sea

The design process of ships is a very complex process that includes many segments and requires several iterations. One of the most important parts that affects almost the entire design process is the load and seakeeping analysis. An important analysis where seakeeping responses have a significant impact is the ship’s operability analysis, which provides an estimate of the percentage of time the ship could be inoperable. Ship designers must have relevant criteria on which to base an optimal conclusion. Estimating the percentage of time that the ship could theoretically be inoperable depends on the limiting criteria for seakeeping, such as the frequency of occurrence of slams, green water, propeller emergence, pitch, vertical acceleration in the forward perpendicular, roll angle, and motion sickness criterion. These various limiting criteria for passenger vessels represent a number in theory than can be interpreted differently in practice during bad weather. This paper therefore gives a critical overview of the limiting criteria already analysed in practice and used in the operability study in the Adriatic Sea.
