Designing a ship's hull is a challenging task. It is our privilege to support you in the process.
We founded the Cloud Towing Tank with the goal of bringing the best of Computational Fluid Dynamics to the marine industry. This is achieved through consistent application of our skills that we formed over years of academic and industrial work on the subject. Consistency is a very important word when it comes to CFD in the marine industry. Consistency in result quality, price and delivery time is very important. Most important of all is consistency of results through time and across different projects. To achieve consistency, we use our internally developed procedures that provide clear paths to calculating specific hydrodynamic problems, minimizing the possibility of a human error while at the same time ensuring the necessary dose of critical human thinking required by every project.
We are Naval Architect PhDs that have been developing the CFD software called The Naval Hydro Pack for 8 years through academic and industrial R&D projects. Numerical ship hydrodynamics is our specialty and we are looking forward to using our skills to help you.
Being the developers of the CFD software that we use enabled us to tailor the workflow in a way that provides standardized and quick calm water resistance and self-propulsion simulations. This is how we can deliver the results to you within as little as one day.
For more specific projects where waves are playing an important role, we have years of experience to fall back to in order to produce the resutls needed for your project.
Your trust is of great value to us, and this is why we offer a free benchmark study so that you can assess our accuracy before working with us. Request your free benchmark today.
Take a look at our R&D work at our Publications page, where you can find scientific and conference papers from a range of topics, showing new developments as well as validation of the code for calm water resistance, self-propulsion, wave loads, seakeeping, maneuvering and others. Also take a look at the list of commercial projects below.
Story & Mission
We both started developing numerical methods for application in the marine industry during our PhD projects, with the vision of helping to solve large problems in the industry, and to make groundbreaking contributions to the field with unique and complex simulations. Over the years we realized that what the industry needs the most are basic CFD simulations like calm water resistance, but that they need to be done in a standardized, industry grade process to ensure consistency and accuracy of results.
We made it our mission to develop a workflow that allows quick evaluation of calm water resistance and self-propulsion while minimizing the room for user error. With our expertise in CFD software development, together with our background in Naval Architecture, we manage to develop a framework that fits your needs as a ship designer. Now, it is time for you to have the full benefit of our efforts, through our Cloud Towing Tank service.
