In this paper, the fluid–structure interaction of floating offshore wind turbine (FOWT) platforms under complex ocean conditions is investigated using OpenFOAM and in-house developed models. Two types FOWT platform, i.e., a semi-submersible platform barge are studied for their dynamic responses to either wave or current. The results reveal that exhibits larger cross-flow motion lock-in phenomen...

This paper describes the autonomous navigation and control of an undersea vehicle using a vehicle control architecture based on the Distributed Architecture for Mobile Navigation and a terrain-aided navigation technique based on simultaneous localisation and map building. Development of the low-speed platform models for vehicle control and the theoretical and practical details of mapping and po...

The goal of this study is to analyze the hydrodynamic behavior a Floating Wind Platform (FOWT) under regular wave conditions. analysis considers three degrees freedom: Heave, Pitch and Surge. was car-ried out using CFD (Computational Fluid Dynamics) tool, based on Navier-Stokes equations Finite Volume Method, results were compared against experimental tests performed at Wave/Towing Tank Univers...

This paper describes an approach to autonomous navigation for an undersea vehicle that uses information from a scanning sonar to generate navigation estimates based on a simultaneous localization and mapping algorithm. Development of low-speed platform models for vehicle control and the theoretical and practical details of mapping and position estimation using sonar are provided. An implementat...

A rapid method for calculation of second-order hydrodynamic wave loads on semi-submersible platforms is developed and validated against radiation–diffraction theory. The based slender-body theory builds modal truncation the quadratic transfer function (QTF). floater split into individual members existing vertical cylindrical columns extended to include heave force. Further expressions surge, pi...
