Overview

In Case Studies in Maintenance and Reliability, The authors describe 42 on-the-job events or situations – case studies taken from their own work experience and from which they gained invaluable insights into a wealth of best practices in maintenance and reliability. In many instances they did not know the underlying academic theories that would have applied. They found solutions often more by intuition and teamwork.

 

The case studies are real, told by the people who were professionally and emotionally involved. The authors have resisted the temptation to offer a set of recipes for all occasions. Rather, the approach is all about "how we did it" rather than "how you must do it". Case study stories are a great way to communicate, and that is the medium the authors have adopted. They've packed the book with common sense ideas on how to improve maintenance and reliability performance.

 

Operations and maintenance technicians, supervisors, managers, planners, schedulers and support engineering teams, as well as designers and project managers will value these dynamic illustrations of real-life situations. Many will recognize similarities to their own work. Students will find the true case studies to be a refreshing change from the usual diet of books emphasizing theory.

Changing Paradigms

…with leadership and expertise


It is paramount for leaders to align the organization so that all are working together to achieve the same objectives.

By Mahen Das


Location: 2.4.1 Medium-Sized Semi-Complex Petroleum Refinery


5.1 Background


The refinery received its compensation on a cost-plus basis, i.e., it received all its operating cost, plus a fixed percentage of that cost. Each partner paid a sum in proportion to the amount of crude processed for it. In such an arrangement, there was no motivation for the refinery to function cost effectively. In fact, the higher the cost, the higher was the fixed percentage of compensation, i.e., the profit.


Over the preceding decade, the refinery had undergone a major expansion. As a result, it had focused on new construction and start-up activities, not maintenance of assets as a business process. Although the people were generally well educated and competent, expertise and leadership for maintenance of assets had been lacking.


5.2 Prevailing Culture


The working culture was quite similar to that in most other places at that time. Departments were securely compartmentalized. The Operations department called most of the shots. The Maintenance department was at their beck and call. Process technologists and advisory engineers had little to do with the overall efficiency of operations. The Materials department was within the Finance function and, with the mental make-up of typical bean counters, had little appreciation of consequential loss due to low quality of maintenance materials or their delayed delivery.

 

The Inspection section (within the engineering function) was very conservative, basing inspection intervals on a fixed-time schedule. Although the regulatory authority allowed considerable flexibility, they preferred to play safe. As a result, all process plants were subjected to annual inspection shutdowns during which almost all equipment was opened for inspection. At the time of these events, risk-based techniques such as RCM and RBI had not been introduced in this refinery, as in the process industry in most of the world. Conservative inspection and maintenance engineers only had past practice for guidance (see also Chapter 10 for some more detailed insights into a similar situation).


5.3 Infrastructure


Computerization of maintenance, inspection, and materials business processes was in its infancy. Computers were used largely as work list repositories. Work planning was fairly advanced. For major projects and plant shutdowns, Critical Path Planning with resource leveling was carried out using commercially available software, CASP®™. However, once the project execution began, there was little or no progress toward monitoring and updating the plan. The critical path charts remained as decorations on the wall.


5.4 Shutdown Work


Preparation for a shutdown mainly meant pulling out last year’s work list, adding the current wishes of the operating and inspection departments, and having it estimated and converted to a critical path plan with CASP®™. The operators added tasks such as shutting down and gas-freeing at the front end, and starting up the plants at the back end separately to this plan. Technologists gave their requirements to the operators for adding to the plan. The project engineers made their own separate mini-plans and appended them parallel to the main plan. There was little coordination of the preparation activities between these departments. In the absence of a milestone chart, these preparations were never completed in time for proper award of work contracts—and contract work was required. This meant that there was never enough time for proper competitive bidding, so prices were higher than necessary. Local contractors maintained a skeleton work force of skilled craftsmen. During big projects, such as a shutdown, they hired temporary workers.


Often, they hired whoever was willing to work, without regard to skills or experience. Contractors and their personnel were viewed with suspicion by the refinery and always kept at arm’s length. During execution of shutdowns, the maintenance engineer was supposed to be the coordinator. Other participating departments did not recognize his role because top management never announced it formally. As a result, the execution was as if there were many separate football games instead of one well-orchestrated team.

Foreword


This book is written by three engineers who have had exceptional experiences in industry, particularly the hydrocarbon process industry. All of them have held positions of authority in the maintenance and reliability of the companies they worked for. A reader will quickly grasp that they were self starters and still are, as evidenced by the creation of this book. These are not men who needed to be pushed. Indeed, I suspect that that would have dampened their motivation to create and install the myriad of solutions and systems that they introduced.

 

The book is a selection of work problems that these men had to struggle with and solve. The chapters penetrate every aspect of field engineering, maintenance, and field management. Each author was able to make contributions to each section. They were able to do this because of their remarkable breadth of experience, which readers will appreciate as they read and assimilate the various sections.

 

In my own career as a field engineer and manager in the process industry, I learned to listen and even enjoy the experience of others. Everything you read in this book will not be directly applicable to your particular job at the moment. However, as you read and enjoy their related experiences you will be storing their experiences in your mind. You will build connections to your own experiences that will make the text memorable. Finally, you will form ideas about how to approach problems that will make your respective jobs easier and more fulfilling.

 

The three authors provide their experiences in facilities in the Middle East, Far East, Europe, and Central America. As a reader, you may want to put yourself in the place of the writers as you study each episode in their long litany of experiences. In this way, you will taste the cultures that formed their experience. I was gratified that the book did not linger on mechanical “How To” ideas, but got to the heart of what makes a refinery, or a machine manufacturing facility, or any production facility really work well. These men are really pointing out, although they do not specifically say it, that the greatest impetus to successful operations is how people manage themselves and set up the procedures that provide rapid and accurate work products.

 

At the end of each of their related experiences, the writer delineates the lessons he learned from that encounter and the principles that emanated from the experience. In reading the draft, I found that the lessons and principles capped the learning; they made the narration of the depicted experiences complete.

 

In summary, this is a must read for people who have to struggle with the day-to-day problems of plant life. If you have a subordinate field position in a manufacturing facility, this book will reveal why bosses do the things they do. If you are in a supervisory or management role, this book will help you steer your career.
