... distribution like Gumbel distribution. This often requires at least 30 to 40 independent 3-hour long realizations to estimate extremes with an acceptable statistical certainty. Combining multiple sea states in each direction along the wave contour diagram, all wave directions and variations in floater draft...

All the pipelines considered show similar trends for departure from the ideal, theoretical Gumbel distribution. As a result, extrapolation to longer pipelines or longer exposure...

Both the table and the figure show that the Gumbel distribution has a superior capacity of accurately describing the calculation error...

... are obtained. The three models, global maximum, block maximum and peak-over-threshold, are used respectively to fit Gumbel distribution to predict structual loads in the long term, with results compared, verifying the comparative rationality of the block maximum method. In the discussion of different block...

... for the wave climate around Taiwan. The values of the shape parameter of the GEV model are found to scattered around zero. This seems to indicate that the Weibull and/or Fréchet distributions are more suitable than the Gumbel distribution for wave climate around Taiwan. INTRODUCTION Nowadays, the majority...
