Progress on the experimental set-up for the testing of a floating offshore wind turbine scaled model in a field site

This document describes design and realization of a small-scale field experiment on a 1:30 model of spar floating support structure for offshore wind turbines. The aim of the experiment is to investigate the dynamic behaviour of the floating wind turbine under extreme wave and parked rotor conditions. The experiment has been going on in the Natural Ocean Engineering Laboratory of Reggio Calabria (Italy). In this article, all the stages of the experimental activity are presented, and some results are shown in terms of motions and response amplitude operators. Finally, a comparison with corresponding results obtained using ANSYS AQWA software package is shown, and conclusions are drawn. The presented experimental set-up seems promising to test offshore floating structures for marine renewable energy at a relatively large scale in the Natural Ocean Engineering Laboratory field site

Ocean Engineering Minor: Use of ROVs for the Teaching of Ocean Engineering

Over the past two years, an Ocean Engineering Minor has been offered at University College London for undergraduate students. The first module of this programme is offered to second-year students and represents an introduction to ocean engineering. This article describes in detail the preparation of the coursework component of this module, which consists in a design and build project of simple ROVs. The aim of the coursework is to help students apply their knowledge of naval architecture to a practical problem and learn about the difficulties and inaccuracies associated with practical work in the process. A detailed description of the project is provided, with an accurate cost break-down so that other institutions may include a similar component in their teaching portfolios. Improvements on the current set-up based on students’ feedback are also described

Naoe-foam-sjtu solver for ship flows and ocean engineering flows

Ship and ocean engineering flows is a very complex and highly non-linear problem. Traditional experimental methods and potential flow theory have limitations in predicting the complex flows. A CFD solver naoe-FOAM-SJTU is developed based on the open source platform OpenFOAM with the purpose of simulating various ship and ocean engineering flow problems. In the present paper, the self-developed modules, i.e., wave generation and absorption, 6 degrees of freedom (6DoF) motion, mooring system and overset grid are introduced to illustrate the development of the CFD solver. Furthermore, extensive applications to ship flows and ocean engineering flows using naoe-FOAM-SJTU solver are conducted and validated by available experimental data. It has been proved that the CFD solver naoe-FOAM-SJTU is suitable and reliable in predicting the complex viscous flows around ship and offshore structures. Future development of naoe-FOAM-SJTU solver will focus on further enhancement of accuracy and efficiency for CFD simulations of complex flows in ship and ocean engineering

Alfond W2 Ocean Engineering Lab

The Alfond W2 Ocean Engineering Lab at the University of Maine Advanced Structures and Composites Center is a unique facility equipped with a high-performance rotatable wind machine over a multidirectional wave basin. The facility will accurately simulate towing tests, variable water depths, and scaled wind and wave conditions that represent some of the worst storms possible anywhere on Earth
