The present paper gives an overview of the performed large scale tests in GWK, Hannover, for studying wave run up generated forces on wind turbine entrance platforms. The run-up height and velocity was measured by use of high speed video recordings supplemented by some wave gauges mounted on the pile. Hereafter, the run up generated impact forces were measured on two types of grates and solid plate. The pressure distribution was also measured for the solid plate. In addition to this the wave generated backfilling of an initial scour hole and the strength of the backfilling soil was studied. The purpose of all the tests was to study scale effects related to the above items by comparison with small scale tests and also to present new guidelines for design

Abstract
The present paper gives an overview of the performed large scale tests in GWK, Hannover, for studying wave run up generated forces on wind turbine entrance platforms. The run-up height and velocity was measured by use of high speed video recordings supplemented by some wave gauges mounted on the pile. Hereafter, the run up generated impact forces were measured on two types of grates and solid plate. The pressure distribution was also measured for the solid plate. In addition to this the wave generated backfilling of an initial scour hole and the strength of the backfilling soil was studied. The purpose of all the tests was to study scale effects related to the above items by comparison with small scale tests and also to present new guidelines for design
