Think Tank Headquarters

Think Tank Division is a dedicated in-house organization specifically tailored for research and development. It has been designated by the Ministry of Science and ICT as one of Korea’s excellent in-house R&D facilities.

CFD (Computational Fluid Dynamics Analysis and Simulation)

Our Think Tank Headquarters uses CFD (Computational Fluid Dynamics) to mathematically reproduce three dimensional fluid flow around the vessel, thereby gaining valuable insights into the various external forces acting on the hull both in scaled and full-scale simulations, such as vessel dynamics (movement), energy consumption, and hydrodynamic efficiency, which are then studied and reflected in our R&D process, allowing us to produce highly precise and reliable results.
