Maritime industry plays a major role in our life and in the economy of the world. Most of the merchandize and goods like electronics, cars, food, clothes, are transported from producers to end consumers by ship containers from one end of the world to the other end. Over the last decades, shipping industry has experienced a continuous growing both in their fleets and in the total trade volume. As a consequence of this growing, it has been necessary the design of new ships and vessels capable of transporting as much as possible of products. This is the reason why nowadays ships are designed using cutting edge technology in order to find an optimal design looking mainly at economic aspects. For instance, modern container ships hulls feature a bow flare and stern overhang in combination with a flow-optimized geometry below the water line. This design is twofold: at one hand it provides maximum space for container storage and at the other hand it provides a minimal water resistance. However, modern designs of vessels and ships seem to be prone to a phenomenon called parametric roll.
