service covers a wide swath over the pipeline's buffer zone, and a general location of the centerline is all that's needed to start the activation. The system setup requires security autho- rization to permit user's access to the web-based system. The PLW system overlays a cover- age outline over the pipe's protective buffer zone including pipeline, and operational assets. The width of the protective buffer zone is dependent on specific operations, population density and/or sensitive environ- mental criteria. Information is ex- tracted by PLW from different data sources and provided as layers on a GIS map. The GIS layers are depicted spatially and managed on an intui- tive, real-time system dashboard Fig- ure 3 shows PLW's dashboard with two overlaid layers with property parcels along the pipeline corridor. The user can prioritize information layers. Example layers are new prop- erty transactions, zoning changes, building permits, road expansions/ realignment, building occupancy, drainage pattern changes. In addi- tion, new monitoring data layers can be developed to fit specific risks iden- tified by a pipeline such as stream levels at water crossings, areal extent of forest fires, earthquake seismic in- fluences near a pipeline. The monitoring service provided by PLW also allows pipelines to provide automatic public aware- ness messaging using the same buf- fer zone coverage to provide advi- sories to property owners or local and regional stakeholders as shown in Figure 4. The PLW system uses a variety of social communication media such as phone calls, emails, and texting to send out messaging. The communi- cations can alert new property own- ers along a pipeline to digging pre- cautions prior to land disturbances. Similarly, PLW provides communica- tions to agriculture property owners prior to seasonal crop management to remind farmers and ranchers to pipeline locations and to utilize 811 call system prior to land activities. PLW's application begins by under- standing the pipeline vulnerability, and application of appropriate moni- toring layers to address the potential problem areas. The vulnerability to external interference is dependent broadly on the urbanization, natu- ral setting, sensitive receptors, and existing pipeline controls. The moni- toring strategy consists of using se- lected risk attributes developed with the operator to screen data sources. The monitoring services are limited to the buffer zone area along a pipe- line segment(s). The alert configuration controls how PLW communicates to the op- erator's organization. These controls also describe how multiple stakehold- ers along the pipeline could be con- tacted automatically by the operator through the PLW service to provide reminders, messages and/or pipeline alerts. PLW's communication service allows companies to send messages to specific parties within the pipeline's buffer zone or specific community stakeholders such as first-responders, emergency officials to advise of an emergency training exercise or other operational events or incidents. GIS is a key component of most pipeline integrity management. Multiple data elements can be served to enterprise GIS systems as a Web Map Service (WMS) or a Web Feature Service (WFS). The Web service augments infrastructure in- formation with near real-time ac- tionable land activities data. The value is through a simple data ser- 34 North American Oil & Gas Pipelines | JULY/AUGUST 2 018 napipelines.com Figure 4 – PLW communication service using different social media forums, through Public Awareness and other channels Figure 5 – PLW Data Architecture & Communications and Security Model
