Safety And The Environment -- "Zero" Really Adds Up

Project gets field issues detected and addressed far faster and more effectively.

While struggling to survive bankruptcy in the early 2000s, Huntsman Corp., The Woodlands, Texas, significantly reduced personnel and some key services. These cuts impacted safety and environmental performance. Reportable safety issues at the company's Port Neches, Texas, facility increased to 45 and reportable environmental releases hit 116 in 2004!

With the leadership of John Prows, vice president of manufacturing of the Huntsman Performance Products Division, and others, as well as initiatives like behavior-based training, Huntsman Port Neches was able to bring these levels closer to industry norms. In 2007, the safety number was down to 33 and reportable environmental releases were below 20. But the questions remained: "How do we follow the company's core values and drive unwanted incidents to zero? How do we go the 'last mile'?"

Prows believed the answer could be found in technology that would give the field operators and maintenance personnel crucial safety-critical and operational data. The idea was that if plant personnel knew the operating limits of critical equipment, they would be able to make safer and more operationally effective decisions. Also, by identifying, capturing and beginning the process of remediating defects in the field, both equipment safety and uptime would dramatically improve.

This vision became "Project Zero."

Running cables or lines to field equipment is expensive and avoiding significant signal noise can pose a challenge. So, to help deliver on the objectives of Project Zero, Huntsman decided to pursue a wireless strategy. It partnered with Industrial Mobility, The Woodlands, Texas, Apprion, Moffett Field, Calif., and Motorola, Schaumburg, Ill.

Huntsman and Apprion began implementing a plantwide network in May 2008 on 400+ acres of the Port Neches production area. To provide Huntsman with complete coverage for access to critical data anywhere and at anytime, more than 90 IONizers, Apprion's multi-radio, multi-protocol access points, were installed (Figure 1). The network was engineered with the future in mind — it was enabled with VoIP capabilities and scalable to support many other applications of wireless technologies going forward.

Simultaneously, Huntsman and Industrial Mobility worked to find, clean up or create critical data needed to bring the plant to world-class levels. This effort included converting Word-based procedures to a step-executable format for use on handheld computers and developing more than 1,200 standard operating conditions (SOC) for guiding field workers in making decisions at the point of need.

Industrial Mobility's MobilOps software brought database-driven functionality for finding, managing and displaying "one source of truth" for operating procedures, SOC, rounds, environmental compliance checklists and other key documents. Additionally, integration was provided for MobilOps to access equipment identification from Huntsman's computerized maintenance management system (CMMS).

A passive RFID tag was placed on each piece of equipment in the field. This enables a field worker to locate that particular item in the database and all documentation about it simply by using a Motorola MC9090 handheld to scan the RFID tag.

Likewise, a defect can be captured just by scanning the RFID tag and entering information about the defect. This information is immediately sent to the CMMS system for maintenance to schedule work. There're no more duplicate work orders or, worse, ignored defects, as happened with the prior cumbersome approach.
