... the disconnections of the mooring system, risers, and land BOP stack is complicated. Moorings are inherently limited because of a ship-shaped vessel's relatively weak motion characteristics. Instead, they have fully advanced DPS. sub-sea system rao drilling equipment spectrum force spectrum frequency...

... the relationship of different cumulative frequency wave height generated by wind and analyze wave spectrums and force spectrums on the pier generated by wind, wave and wind and wave coupling and the relationship between these wave spectrums and force spectrums. Results indicate there is the strong relativity...

... ABSTRACT In this paper, wave loads on a surface piercing vertical cylindrical pile are presented using the spectral and monochromatic approaches. While the basis of wave load computation for both the approaches is the Morison equation, the spectral method is dependent on the force spectrum...
