Anchoring systems for deep-water floating structures must withstand complex, hydro-mechanical (H-M) coupled uplift forces throughout an operational life extending over decades, yet fundamental understanding of this complicated H-M behavior remains insufficient. This paper presents a comprehensive review of H-M coupled foundation–seabed interactions under uplift loading. Key experimental findings are synthesized to demonstrate...

Tethered unmanned surface vehicle (USV) and remotely operated vehicle (ROV) systems are widely used in deep-sea inspection, observation, and intervention tasks. During cooperative operations, the USV must follow the mission trajectory of the ROV while avoiding surface obstacles and maintaining a prescribed tether-related safety envelope. This study proposes a multi-objective nonlinear model predictive control (NMPC) framework...
