The Approach
To identify the components and the required inputs for Shell to create simulation models using the Simio Tool (“Simio”), a probabilistic vessel scheduling software. Use of Simio enabled predictive analysis for expected operations by optimizing voyages, proactively share vessels transiting to a common field area and enabling the business to maximize the vessel’s capacity for offshore asset material movements.
Modelers are able to use the simulation aspect of the tool to ascertain the validity of the model configuration and identify further opportunities to align to operational variances. Further, it helps to identify parameters that may be exposed for schedulers to adjust settings to better reflect “typical” operating conditions (e.g. Lift rates or bulk loading times, vessel transit speeds).
Using the models and iteratively-updated information, helps create schedules that allow for in-depth operational planning involving vendors, vessels and offshore locations. Using the latest weather, demand requirements, and vessel information, the IT tool optimizes the use of the vessel fleet and improves efficiency of port operations. Schedule data shows when materials need to arrive at the port, which vessels are to be loaded, expected load times, vessel transit routing and offloading times.
Resulting schedules need broad visibility by Shell Internal resources and Third-Party External partners. This has been accomplished by periodic updating of the current schedule to Simio Portal (Web Facing Software-as-a-Service) where users can view their scheduled voyages for planning or confirmation purposes.
