EXPERIMENTAL STUDY OF STABILITY LIMITS FOR SEMISUBMERSIBLE DRILLING PLATFORMS

The existing stability criterion for semi-submersible drilling platforms requires thirty percent margin of righting moment energy over wind heel energy to allow for dynamic effects. This second report of a series uses model test results to predict the statistical probability of a downflooding type of casualty for various sea conditions. A six-column twin hull semi-submersible and a four-column footing type vessel are examined in an attempt to test the adequacy of the existing stability criterion.
