Abstract
A method for evaluating a securing system for a floating structure, where the method includes collecting a plurality of metocean data from a plurality of metocean sensor devices during a current time period coinciding with a field operation, where the field operation is conducted from the floating structure that is stabilized by the securing system. The method can also include evaluating the metocean data using a plurality of algorithms. The method can further include determining, based on evaluating the metocean data, a condition of the securing system at the current time period.
Claims19
