... that the asymmetric factor depending on the number of resampled realizations from 16 seeds. INTRODUCTION The wave-in deck event can cause the large horizontal and vertical impact load on the offshore structure, thus it is important to evaluate upwell (relative wave elevation) around the platform. Nowadays...

... line stiffness and random seed for realization of irregular waves. INTRODUCTION There are high interests in float-over installation which can install heavy structure at one time, especially as topsides facilities are becoming larger and heavier. Key issues during docking that DTV enters slot...

... plus different realizations of finite variance white noise. Let x be the signal of interest. The EEMD algorithm can be described as follows (Wu & Huang, 2009): Step 1. Generate x(i) = x + w(i), where w(i) (i=1I) is a zero mean unit variance white noise realization, and > 0. Step 2. Decompose completely...

.... In this paper we first study the higher than second order effects in long crested seas from 20 different wave spectra in intermediate to deep water. From each wave spectrum there has at least been performed 10 realizations. We have looked into the higher order effects with respect to the steepness, skewness...

... and the structure is retained from any motions. Test runs in random waves with 20 different seed number realizations of the Torsethaugen type sea state with H s = 20.7 m, Tp = 20.1 s were generated with a full scale duration of three hours. From each 3-hrs realization the sample extreme impact event is identified...
