.... To realize this function, 3-day and 5-day are selected as the fixed time intervals, which are used to obtain the sample to extrapolate extreme significant wave heights with return periods of 100-year, 200-year and 500-year at 4 locations in the Yellow Sea (YS). INTRODUCTION Adequate extrapolation...

... ABSTRACT In this paper we show how a new idea for how to calculate the derivatives of extrapolated 50-year return values, used in extreme load safety criteria, can be used to estimate the uncertainty in these return values resulting from uncertainty in the simulations and in the load...

... ABSTRACT Prediction of extreme loads by statistical extrapolation, using short-term distributions to obtain the long-term distribution, is crcucial for offshore wind turbines. According to the requirements of the IEC61400-3, data from simulations of four types of 5MW offshore wind turbines...

... ABSTRACT: Extrapolation plays an essential role for evaluating sea extremes frequencies, which is why the concept of return period has been introduced. But we use the return period (or the extrapolation) without being aware of the hidden double meanings. Speaking shortly, the return period...

.... Due to the depth limitation of the wave basin, mooring system was truncated with the hybrid model testing technique. Numerical validation with the truncated mooring system e.g. numerical reconstruction was performed to verify the model test. Extrapolation was also carried out to predict...

... the linear extrapolation method. The probabilistic averaging approach was found to produce significantly lower estimation errors than the linear extrapolation approach. Fullscale issues for correlation modeling and global load estimation are discussed and recommendations for further work are provided...

... Fatigue design rules for offshore structures are based on research work of relatively small welded joints for financial reasons and for ease of experimentation. However, extrapolation of the results to bigger and thicker welded joints may not be safe, especially for extra thick joints...

... The local stress in the vicinity of web-stiffened cruciform connections in ship structures are examined using various shell FE-based techniques. The employed techniques are a) SR202B method (0.5t-1.5t extrapolation technique), b) DNV CN 30.7 method (modified 1-point method), c) CSR-B's...
