Abstract: A method of estimating risk of at least one accidentally dropped object load from at least one crane on a platform or vessel includes providing or generating a schematic representation of a sea level area; 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; 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.

Abstract: In a method of delay estimation and a project management tool with at least a delay estimation module, the delay estimation module and the method of delay estimation estimating delays at least by dividing a work breakdown structure of a project plan in a plurality of elements, identifying a plurality of risks and uncertainties in connection with the plurality of elements provided in the work breakdown structure, estimating a plurality of best duration uncertainty distributions for each element of the plurality of elements, synthesizing, using the plurality of best duration uncertainty distributions, a work breakdown structure of a project plan with uncertainties, and creating an estimate of delays for the project plan.
