Abstract

A combined discrete-event/continuous/process-interaction simulation model has been developed to evaluate the effects of weather and supply-ship availability on off-shore drilling operations at a specified location and time of year with a specified drilling vessel. The continuous submodel includes: (a) autoregressive-moving average and transfer-function models to represent weather conditions; (b) a difference equation to monitor effective work time for the current operation on the drilling vessel; (c) difference equations to govern supply levels on all vessels; (d) state-events to stop and restart operations on all vessels; and (e) difference equations to control the movement of supply ships. The process-interaction submodel represents the flow of supply-ship traffic and the overall operation of the drilling vessel. The discrete-event submodel controls the loading and unloading of supply ships as well as the alternation of periods of calm and stormy weather.
