OLM stands for “Office de la Mer et des Littoraux,” which is a French organization that provides training for boaters who want to improve their skills and knowledge in navigating through rough waters, particularly in waves and choppy conditions.
In this way the trainee learns how to pass big waves. I’ve posted more videos for you to enjoy like here, here and here.
This training is designed for experienced boaters who already have a basic understanding of boating techniques and safety practices while minimising the risks of accidents and injuries.
It makes it relevant for those who navigate in coastal or offshore waters, where the sea conditions can be unpredictable and challenging.
If you listen carefully you can grab some tips and advice. It is in French though and the author did not active subtitles.
As a naval architect, the computational fluid dynamics (CFD) is an essential and vital tool for analysing the hydrodynamic performance of boat hulls. Prior to finalising the hull design to build.
By simulating the flow of water around the hull using numerical methods and algorithms, CFD allows them to predict the resistance, drag, and lift of the boat.
Using CFD simulations, they can optimise the hull shape for speed, efficiency, and stability by testing various design iterations without the need for physical prototypes.
This helps them to reduce the time and cost of the design process while still ensuring optimal performance.
In the simulation process, naval architects typically divide the fluid domain into small cells and solve the Navier-Stokes equations for each cell to calculate the fluid properties such as velocity and pressure.
Many of us have probably been in a situation where the wind picked up and the sea was agitated; after all, you had checked the weather and sea conditions beforehand. There are a lot of good apps for that, by the way.
