The proposed cruise jetty is designed initially for the two Oasis-class cruises docked on the two sides at the same time. Based on the deepwater wave parameter at certain water depth outside open ocean area of the project, a numerical nearshore wave model using high order parabolic mild slope equation is applied to calculate the wave propagation and deformation in the coastal waters of the project area. General Bathymetric Chart of the Oceans used were compiled and distributed by publicly available oceanographic data centre. The tide gauge data is analyzed based on two hydrological observation stations around the project area. With the setup of breakwater, open seas wave is impeded during propagation, diffraction appearing at the head of breakwater. Based on the wave parameters in different directions in front of breakwater, the wave height distribution in the harbor can be obtained depending on the combined refraction-diffraction wave model in the harbor basin.
With the growth in cruise business, cruise ports are gaining in importance. Selection of destinations is to some extent conditioned by the state of the cruise port to visit. The port is vital for assuring schedule reliability and for allowing a continuous passenger (dis)embarkation and transfer to onward journeys and/or day excursions. Once market characteristics result in cruise lines expressing an interest in established or potential destinations, economic and geopolitical conditions permit, the competency of a destination relies on port and shore characteristics (Lau et al., 2014). The presence of sufficient port specific and port related infrastructures, the absence of intense use that might lead to congestion and process disruption, and the modernisation of infrastructures and processes so as to provide efficient and effective port services, are key to allowing the usage of a port as part of an itinerary.
Sea state is a vital consideration for the selection of a cruise port (Pallis, 2015). Wave–prediction and hindcast studies are important in ocean engineering, coastal infrastructure development and management. Knowledge of parameters describing the wave field, currents and water level is essential to almost all marine related activities. Wind–generated ocean surface waves are identified as the major driving force for nearshore circulation and sediment transport in the surf zone and inner continental shelf (Wright et al., 1991). As the waves approach shallow water, wave energy spectra evolve due to refraction and energy dissipation, a partial function of wave breaking and bottom friction (Thornton and Guza, 1983).
