This paper describes a CFD based approach to the design of a Pre-Swirl Stator (PSS) to be used as Energy Saving Device (ESD) on a retrofit chemical tanker. The designed PSS is shown to deliver 4% power savings at vessel selfpropulsion condition through a relevant speed range in full scale. This is c...

As the offshore wind industry moves toward deeper water, with larger turbines and correspondingly larger monopile foundations, nonlinear loads from steep waves may become more important for the ULS design. Nonlinear numerical wave tanks (NWTs) for generating wave kinematics, to be used as input to i...

This paper presents experimental results of the forces and moments acting on a single propeller blade running in ventilated conditions in calm water and in waves. A model of a Rolls-Royce Azipull thruster with a four-blade propeller was tested with provisions to measure three orthogonal moments incl...

In order to obtain insight into the effect of waves and ventilation (air drawing) on propeller loading and dynamic fluctuations, tests of a model open pushing thruster were performed at different immersion ratios in different regular waves at different advance speeds. A high sampling frequency was e...
