METHOD OF ESTIMATING RISKS CAUSED BY ACCIDENTAL DROPPED OBJECT LOADS TO SUBSEA PIPELINES OR OTHER SUBSEA ASSETS ASSOCIATED WITH OFFSHORE OIL & GAS AND MARINE OPERATIONS
First Claim
1. A method of estimating risk of at least one accidentally dropped object load from at least one crane on a platform or vessel, comprising:
- providing or generating a schematic representation of a sea level area comprising at least a layout of the platform or vessel and a layout of a maximum and minimum crane handling radius of the at least one crane;
identifying a drop area for accidental drops of the at least one accidentally dropped object load from the crane based on image processing of the schematic representation of the sea level area;
estimating probability density of risk of accidentally dropped object loads based on a multitude of drop points within the drop area for the at least one accidentally dropped object load or at least one object category; and
representing the sea level area, the subsea area, and estimating probability of risk of accidentally dropped object loads using data representations in the form of at least one of matrix-type data, raster graphic image, or dot matrix data for location, estimated risk values and other statistics.
