Analyse dynamique non linéaire des amarres en eau profonde et peu profonde

Ce projet de recherche a pour but d’élaborer un programme informatique permettant de prévoir le comportement d’amarres en fonction des vagues et des courants. On calculera les tensions exercées et les charges au niveau des ancres. L’intégration du programme informatique à un outil d’analyse du mouvement de navires permet de calculer des valeurs combinées pour […]

Computation of Wind Loading on a Shuttle Tanker during FPSO Offloading

Wind forces on an offloading tanker that is approaching a Floating Production and Storage Offloading (FPSO) vessel are influenced by so-called shielding or shadow effects, which are caused by the distorted wind fields in the wake of the FPSO. During the offloading operations, an offloading tanker approaching an FPSO will experience changing flow conditions that […]
