**Announcement** We are pleased to confirm that naval architect Laura Taylor has joined TMC Marine. Laura brings first-hand experience of new and developing technologies which will complement our alternative tech and carbon transition teams. The move to TMC Marine allows Laura to focus on #technical consultancy drawing on her experience across different vessel types particularly in the fields of #futurefuels, #electricvessels, LNG and emerging technologies. #marinenews #marineindustry #cleanfuel #shippingnews

To further our contribution in the Gaters project, sponsored by the EC H2020 Programme, NAS Ltd. - Naval Architectural Services recently published a paper in the Offshore Energy and Storage Symposium (OSES2023) (https://lnkd.in/dfpwcpNp) with the following title: “The Full-Scale Performance Prediction of a General Cargo Ship with a Retrofitted Gate Rudder System using CFD Procedures” ⛵.   This time round, the goal of the study was to predict the performance of the General Cargo vessel with the Gate Rudder System (GRS) at ship-scale conditions using state-of-the-art CFD techniques and the results were compared to the model-scale CFD results and extrapolated towing tank test data. These studies built on the previous work that focused on model-scale simulations, published at the AYOCOL Conference (https://lnkd.in/dfGCMNYa) in December 2022.   Once again, as was deduced from the model-scale analysis, the GRS blades produce a thrust, as opposed to the conventional rudder which produces a resistance. However, in full-scale, the GRS performed even better, as the thrust produced was several times larger than that obtained for the model scale simulations: more than 20% reduction in delivered power compared to the conventional rudder system!   Therefore, our findings show that the thrust produced by the GRS blades in full-scale lead to an even higher reduction in power demand and fuel consumption ⬇⛽💰 , when compared to the conventional rudder system.   Head to the link below to find out more about the Gate Rudder System and the Gaters project! 🔎 https://lnkd.in/d_aRxaBn

TECHNOLOG Services GmbH required dispersion analysis as part of a hazard study on a new ammonia-fuelled vessel design. They were looking for an efficient and cost-effective solution that could be used immediately. One solution stood out: #PhastOnline. “Getting the calculations running was quite straightforward and user-friendly. With only a few parameters as input data it is possible to get first results,” says Naval Architect Robin Kloske at TECHNOLOG Services.

🌊⛴️ Optimizing the hull form of a ship can significantly reduce resistance and improve fuel efficiency? 🚢💨, Check out how GridPro was used to perform 120 simulations overnight with automatic structured meshing of ship hulls. Analysing the shape of the hulls, naval architects can minimize drag and increase speed, ultimately saving on operational costs and reducing environmental impact. #ShipDesign #NavalArchitecture #FuelEfficiency #meshing #cfd #SustainableShipping 🌊⚓ https://lnkd.in/gyzqxxEz

We're thrilled to inform you about a paper that we recently published: " The Performance Prediction and Energy Saving Evaluation for the Retrofit of a Gate Rudder System on a General Cargo Vessel using CFD Procedures". 📑 As part of the Gaters project, sponsored by the EC H2020 Programme (No.860337), NAS Ltd. - Naval Architectural Services, in collaboration with the University of Strathclyde , presented interesting findings at the AYOCOL Conference in December 2022.   🔍 Our study harnessed cutting-edge CFD techniques to predict the impact of retrofitting a Gate Rudder System (GRS) on a General Cargo vessel. The results are promising: GRS blades generate thrust, unlike traditional rudders that cause drag. This translates into reduced power demand and fuel consumption, reshaping the future of maritime efficiency. 🌊⛽   But that's not all! The GRS was successfully retrofitted on the real ship and the benefits were clearly demonstrated during Sea Trials post-drydock. 🛳️📊   Ready to dive into the details?
