Abstract. Wireless devices and systems have been deployed in many commu-nication sectors but have not yet been adequately adapted to harsh industrial environments. Cost effective, reliable and scalable wireless technologies have yet to be introduced in industrial plants, including petroleum plants. At this time, there are very few, if any, cost-effective Commercial-Off-The-Shelf (COTS) radios available that can be used to provide reliable data links under the very harsh conditions encountered in petroleum environments. This paper presents a strategic approach to research wireless system technologies and their application to the oil and gas industry, specifically for asset integrity and auto-mated diagnostic CBM applications.

Introduction and Strategy

The failure of critical operational equipment in the petroleum industry is a

major expense because downtimes mean a loss of revenue to the companies. Recent

study [5] has shown that inaccurate predictions of lifetime of equipment costs about

$1 trillion per year in replacing good equipment. To mediate this, companies may

choose to employ Condition-Based Maintenance (CBM) strategies that maximize

operational uptimes and minimize equipment repair and replacement. CBM requires

timely, reliable, up to date, and cost effective data collection for reliable equipment

failure prediction [8].

Currently the petroleum industry pays high labor charges for skilled

techni-cians to run routes with data collectors on a regular basis as part of (CBM)

proce-dures [5]. This labor intensive solution is not always timely and cost effective. An

alternative solution involves hard wired data collectors. The costs of installing such

(4)

dedicated solution is very expensive due to the cost of conventional (copper, fiber

optic) wires. Some estimates are as high as $2000 per linear foot! Plants operating in

rigorous environments with extremes of high and low temperatures, rain, snow, ice,

and harsh or corrosive chemicals mean even hardened cables must be replaced every

6 months and cost estimates in the order of $6 - $8 million are certainly possible

depending on the project.

A reliable, robust and rugged wireless mesh networking architecture, apart

from solving the cable issue, could provide near real time monitoring capability. This,

integrated with existing CBM trend analysis software, can help predict equipment

failure in a timely fashion. However, the electromagnetic environment in a petroleum

plant is a challenge for implementing any wireless communication technology. We

propose to design a power-efficient, robust wireless mesh network that involves

care-ful modeling [7] of the wireless channel followed by suitable transceiver architecture

implementation [6] [2], signal processing [1] [3] and cross layer protocol stack [4]

designs.
