A SYSTEM AND METHOD FOR DETERMINING THE SUITABILITY OF PREVAILING ENVIRONMENTAL CONDITIONS FOR OFFSHORE OPERATIONS

摘要

A method for determining the suitability of prevailing environmental conditions for an offshore operation on a vessel, the method comprising detecting the motion of at least a part of the vessel and comparing the detected motion with a predetermined maximum permissible motion or assessing numerically the effect of the measured motion to enable determination of the acceptability of the detected motion for said offshore operation. Preferably the method includes the initial step of creating a numerical model of the vessel and utilising the model to establish a first data set representative of the maximum permissible motion of said part of the vessel as a function of frequency, in at least the Z or vertical axis, and storing said first data set for use in said determination.
