Abstract:
1. A method for computer generating a gap assignment model for managing and tracking gap closure activities for a safety instrumented system of a facility, wherein the gap assignment model has at least one action plan name and the gap assignment model uses a real world model of an instrumented protective function, wherein the method comprises: a. connecting a processor to a data storage and a network to communicate with at least one client device; b. using non-transitory computer instructions in the data storage forming a type of work library for a facility having work names, wherein each work name includes a work name identifier, and an impact identifier; c. using non-transitory computer instructions in the data storage forming an accountability library having single points of accountability, each single point of accountability includes a work name identifier, and a single point of accountability name; d. using non-transitory computer instructions in the data storage forming a stakeholder library for a facility having stakeholder name and stakeholder description; e. using non-transitory computer instructions in the data storage forming an action library for a facility comprising: f. using non-transitory computer instructions in the data storage forming a library of instrumented protective function library for a facility having an instrumented protective function identifier, a name of an instrumented protection function (IPF), an achieved risk reduction factor, and a real work model of instrumented protective functions for a facility; g. using non-transitory computer instructions in the data storage to form a layer of protection analysis with target risk reduction factor; h. using non-transitory computer instructions in the data storage forming an action plan library, wherein the action plan library comprises: i. using non-transitory computer instructions in the data storage to simulate solutions to close a gap in safety or a gap in environment between the retrieved target risk reduction factor and the retrieved achieved risk reduction factor and display a hypothetical percent of risk reduced by each solution; j. using non-transitory computer instructions in the data storage to calculate a relative risk reduction factor for each action connected to an action plan, and using the real world model with the instrumented protective function and the instrumented protective function identifier to form a gap assignment model for a facility having at least one instrumented protective function; k. using non-transitory computer instructions in the data storage to identify an action state for each action connected to an action plan created in the gap assignment model; l. using non-transitory computer instructions in the data storage to calculate a work in progress risk reduction factor for an action plan with actions that have been marked as work in progress; and m. using non-transitory computer instructions in the data storage to calculate a remaining risk reduction factor for an action plan with actions that have been marked as work in progress.
