KRISO Container Ship (KCS)

The KRISO Container Ship (KCS) is a benchmark hull form created around 1997 by the Korea Research Institute of Ships and Ocean Engineering for CFD validation and flow-physics study. It models a modern single-screw container ship with a bulbous bow and a transom stern, about 230 m long at the design waterline with a block coefficient near 0.65 and a design Froude number near 0.26. Public towing-tank resistance, self-propulsion, and wave-field data from KRISO and from the Tokyo 2015 and Gothenburg CFD workshops make it one of the most-used cases for verifying RANS resistance, wake, and self-propulsion predictions. The KCS hull has no full ship built to it; it exists as a research geometry.
