Teignbridge Propels Interest at HRV1 Sea Trial
Torbay Harbour and Royal Torbay Yacht Club // Teignbridge Propellers hosted a group of members of the marine community recently to experience the HRV1 research vessel in action. Guests were able to see live-action, first-hand data onboard the MCA category 4 coded catamaran. Back on shore at the Royal Torquay Yacht Club, Teignbridge explained how data from physical testing on-board HRV1 is coupled with numerical simulation tools in an integrated design workflow to deliver high performance propellers.
Amels Launches New 180 Yacht
Dutch yard Amels has launched the 23rd model in its Amels 180 Limited Editions range, which has been named Papa.The 55-metre Amels 180 superyacht was the first of many new Amels superyachts nearing completion for their owners before the summer season begins.For the yacht’s crew, the launch is a milestone bringing the maiden voyage closer after many months working together with the Amels team. Captain Paul Bessant commented: “The teamwork here, the way that you feel so involved with everything, the relationship with the project managers.
World Premiere of K2X Allround Catamaran at ‘boot’
Germany’s largest catamaran builder, TOPCAT has launched a world premiere at the 50th international water sports exhibition in Düsseldorf. The 17-foot-long (5.17 meter) K2X model is conceived as a sporty, fast and reliable allrounder. Not only can it be sailed in typical two-crew mode, but – thanks to its hull shape which offers a high degree of buoyancy – is equally capable with a family of four on board or for single-handed sailors. This newcomer completes the now fully revamped model range in time for the 40th anniversary of the company.
The Role of Simulation Software in Yacht Racing
Cape Horn Engineering was founded in 2007 with the vision of using the best available CFD tools for the design of racing yachts. They have been involved in several America’s Cup campaigns and their designs have dominated the Around-the-World Volvo Ocean Race for almost a decade, winning three times in a row, with ABN Amro (2005/06), Ericsson Racing Team (2008/09) and Groupama Sailing Team (2011/12). Cape Horn Engineering is proud to be involved in the design team at Land Rover BAR…
New Operational Structure for Van Oossanen
Netherlands-based Van Oossanen Naval Architects is continuing to trade under the name Van Oossanen. Van Oossanen will act as the Van Oossanen Group, incorporating Fluid Dynamics, Naval Architecture and Hull Vane BV, an independent company established by Van Oossanen. According to Van Oossanen , the renewed business structure follows its growing activities for Computational Fluid Dynamics services in the commercial shipping market. As a separate service from naval architecture, Van Oossanen Fluid Dynamics will operate independently within Van Oossanen.
ANSYS Speeds International Yacht Race Winner
Powered by ANSYS solutions to maximize yacht aerodynamics, 'Emirates Team New Zealand' has captured the Louis Vuitton Cup and won the right to compete in the 34th America's Cup. Faced with the challenge of making fast design improvements to its yacht to stay hyper-competitive, Emirates Team New Zealand used a 100 percent simulation-driven development process — eliminating the need for physical prototypes. Team engineers used ANSYS® computational fluid dynamics (CFD) solutions to virtually test different designs, considering up to 750 operating conditions per design.
Virtual Towing Tank State-of-the-Art and Future Trends
The use of computers to solve hydrodynamics problems in shipbuilding started in early days of scientific computing – as early as in aerodynamics and aerospace. Due to limited computing resources at that time, potential flow model was used in both aero- and hydrodynamics. However, while simulations based on Euler equations, Reynolds-averaged Navier-Stokes equations (RANSE) and most recently partially resolved Navier-Stokes equations (so-called “large-eddy” – LES – or “detached-eddy” – DES – simulations) have become established tools in aerodynamics…
Eye on Desgin: Improved Propulsion
Fuel saving and emission reduction are motivating factors in the drive to improve marine propulsor technology and in the renewed interest in special devices that improve propulsion. Together with the industry, MARIN is actively investigating their working principles and the critical design aspects, using modern design and analysis tools. Fuel efficiency and reduction of CO2 emissions are expected to have a strong influence on the design and operation of ships. With the arrival of the Energy Efficiency Design Index (EEDI) in 2013…
