In this study, the dynamic responses of an oil tanker moored on a Catenary Anchor Leg Mooring (CALM) buoy were simulated under wave, wind and current through numerical simulations. Then tension mooring lines drift range studied after system failure. Simulations done with ANSYS AQWA Orcina OrcaFlex. Hydrodynamics was first solved in frequency domain based potential theory, three-dimensional radi...

Floating breakwaters are widely used due to their various advantages over stationary breakwaters. Lots of researches have been done on hydrodynamics and the type of bracing of these kinds of structures in recent years. In this study, numerical modeling of stresses caused by collision waves has been investigated. For this purpose, samples of floating breakwaters have been modeled in ANSYS softwa...

Abstract The article presents a design of floating platform for offshore wind turbines. concept is modification the Spar and consists three variable section columns connected to each other by ballast tank in lower part platform.

Wave energy has much more potential and benefits than other forms of renewable energy. It is predictable, consistent, controllable wind or solar In this way, an adequate infrastructure can be alternative also sustainable system for power supply. paper, different wave conversion mechanisms (buoys, Pelamis, oysters) have been described. These models are implemented simulated using the Design Mode...

Large caissons are extensively applied as deep-water foundations in marine engineering. In fact, generally prefabricated and transported to project site by wet towing. Motion responses of large those occurring during the towing process were investigated, CO2 emissions under various conditions calculated. These all considered ensure safety environmental protection. The caisson resistance coeffic...

This paper utilizes ANSYS-AQWA hydrodynamic simulation analysis software (2022 R2) to investigate the wave dissipation performance of an Oscillating Water Column (OWC) perforated floating breakwater under irregular conditions. The study examines effect spacing, width OWC opening, water depth, incident angle, and significant height on breakwater. results indicate that OWC-perforated surpasses si...

This investigation focuses on the modelling of a floating oscillating water column (FOWC) wave energy converter with numerical code (ANSYS AQWA) based potential flow theory. Free-floating motions predicted by model were validated against experimental data extrapolated from 1:36 scale device in regular and irregular sea states. Upon validation, an assessment device’s when dynamically coupled fou...
