... Abstract This paper aims to investigate the impact of controller parameters on the performance of a PID controller in the maneuvering of two ships. In present work, a maneuvering model, which accounts the hydrodynamic interactions, is established using the MMG model. The shallow water effects...

... was conducted. A frequency domain hydrodynamic performance analysis of the floating photovoltaic platform was performed using the hydrodynamic analysis software AQWA, which includes platform RAOs (Response Amplitude Operators), hydrodynamic interaction characteristics, and shielding effects. Using...

... Abstract The situation of two ships maneuvering in the vicinity is not so rare, and the significant hydrodynamic interaction effect always poses a threat to navigation safety in these conditions. The assessment of distance at closest point of approach (DCPA) is necessary for ship collision...

... force we can maximize the power generation of PA-WEC. One of the feature points to make an array of PA-WECs is taking positively the hydrodynamic interaction among the array like trapping waves among the array to maximize the power generation. As for the maximization of the power generation...

... and flexible way for offshore drilling, especially with TLP. Dynamic response of tender-assisted drilling system is crucial due to the safety concern. However, some urgent issue has not been thoroughly studied in tender assisted drilling operation like the hydrodynamic interaction and the impact...

... Absorber Wave Energy Converters (PA-WECs). In the array, complex hydrodynamic interactions among the array will occur. The interaction influences the wave power density among the array both increase and decrease. When we consider the maximization of generated electric power of the array, the suitable...

..., a simplified system with seven interconnected standardized modules is proposed for numerical and experimental study. In this simplified system, each module is assumed as a rigid body. Both hydrodynamic interactions and mechanical coupling among modules are taken into consideration in the time-domain numerical...
