Recently, a method for numerical reproduction of measured irregular wave events has been developed. The measured motion of the wave maker flaps defines the wave kinematics at the boundary of the numerical simulation in order to generate the waves. When such data are not available, the control signal...

Effect of roughness on frictional resistance is investigated experimentally and numerically. Resistance tests are performed with several plates coated with different paints, which have different roughness. Front plate is 4 m long and aft plates are 6 m long resulting in a total hydrodynamic length o...

A procedure is presented describing how to estimate realistic loads using combined numerical and model test data. Measured platform motions are imposed on the structure during the CFD analysis. The combination of the wave matching procedure with the imposed measured platform motion gives a very good...

In order to provide qualitative and quantitative information on the hydrodynamics loads during green water events on a module on the deck of a TLP in 10000-year conditions, MARINTEK has carried out CFD simulations. This paper presents extreme wave events and corresponding hydrodynamics loads on the ...

This paper presents results from model tests and CFD simulations of lifeboat launches in regular waves. To the authors’ knowledge, this is the first time CFD simulations of lifeboat launches in waves have been validated. The predicted accelerations agreed well with the measured ones. The pitch veloc...
