Abstract
Abstract A system for assessing the structural integrity of offshore drilling platforms employs structural moment detector and associated electronics, microprocessor and software, which monitors the condition of the offshore platform structure and continuously provides useful information concerning the effects of external forces on the structure and its remaining life.

Claim 1
Independent Claim
116 words
A system for collecting and interpreting data reflecting the effect of at least a selected one of a plurality of forces on an offshore platform structure, said system comprising, in combination: (a) at least one structural moment detector carried by said structure for generating output signals in response to said plurality of forces acting on said structure; (b) means for processing said output signals to modify the information content thereof, including rejecting components of said signals which reflect the effects of extraneous forces other than said selected one; (c) means for manipulating said processed signals to provide secondary signals responsive to the condition of said structure as a result of the application of said selected force.
