ROLE OF THE FIELD ENGINEER IN SAFETY
The Piping or Mechanical Field Engineer is a direct contributor to the safety of the work operations at the construction site. Since all safe work operations must begin with preplanning, the Field Engineer makes a direct contribution to safety by reviewing the planned work with safety in mind. The Field Engineer is typically responsible to develop a detailed work package for work planned by the Superintendent, verify the required materials are available and obtain the required permits to perform the work. The following specific types of questions might be asked by the Field Engineer to ensure the work can be done safely:
- How will the materials get to the work location? Can preassembly be done to avoid performing work in tight or cramped quarters?
- Does the work require the use of hazardous materials? Are MSDS sheets available at the site for all materials that are required to be used?
- Have all the required permits (e.g. confined space entry permits) been obtained to allow the work to be performed? Are there any special requirements that supervision or the craft need to be aware of prior to starting the work?
- Have all special equipment tagging requirements been satisfied?
- Are all the required materials available on the site? Have the materials been inspected for damage or flaws that might cause injury during installation?
- Has a thorough review for potential underground obstructions such as existing utilities, energized electrical cables and process lines been performed prior to authorizing the work to proceed?
- Is the proposed work site free of potential fire hazards? Is the housekeeping adequate?
- Are trenches or excavations adequately sloped or shored? Is a special shoring design required due to the depth or location of the excavation or trench?
- Have required rigging plans been prepared and approved? Have the requirements of the approved rigging plan been reviewed with the craft who will perform the work?
- Is the scaffolding required to perform the work properly erected? Is a special scaffold design required to access the work location?

Last year, our Oil & Gas was in a great boom phase, and there were lots of projects coming with vacancies filling up. We (in board meetings) every few months were being told and assured that work is coming and lots of it. Indeed, we had a pile of backlog always in work, and 2016 looked so promising to us. But then all of a sudden, at the pace we had work coming got slow. Rumours started that company has taken out some contractual and much more. Although none of them was real, until 2016 started. Suddenly company started running out of work or had existing tasks to complete quickly before that goes out of hand too. Does that call for Recession? At least for me, Yes!
Why is Recession Back?
A slump is petroleum industry is not a new thing we may hear. We have seen these before, like in 2009-2010 and now after five years, its back. The only difference between the previous and the current one is, this slump is affecting jobs worldwide. While the production rate has not slowed down, the requirement of Oil is going flat or dropping. Of course, time will come when the markets stabilize, and prices of Oil may rise again. But this time, I think it'll be slow, and there are many Geopolitical issues which first needs to be resolved.

When compared to other equipment in a hydrocarbon processing plant, the piping network is designed to the most stringent standards. Mechanical Engineering codes require a 400% safety factor in the design of these systems. The piping system is normally considered the safest part of the plant. However, even with this level of safety, reviews of catastrophic accidents show that piping system failures represent that largest percentage of equipment failures.
Since these systems are responsible for many catastrophic accidents, operations, design, and maintenance personnel should understand the potential safety concerns. The best tool that we have to prevent future accidents is to review past incidents and incorporate lessons learned into future design and operation of piping systems.
This paper will discuss various case studies that will help to illustrate the consequences of inappropriate design, operation, and maintenance of piping systems. The case studies include:
1) Check valve failures;
2) Small bore piping in compressor discharge piping,
3) Low temperature embitterment, and
4) Hot tapping safety issues and hot tap shavings concerns.
Check Valve Failures
Check valves are important safety devices in piping. Check valves have been utilized in the process industry for many years to keep material from flowing the wrong way and causing operational or safety concerns. One common mistake is installing the check valve backwards and blocking the process flow. There is normally an arrow on the check valve designating the proper flow direction, indicating the proper installation position. There have been cases where the manufacturer showed the arrow incorrectly, which greatly hindered troubleshooting.

To know piping design basics by going through the following points:
- Design of pressure components.
- Pipe Span calculations.
- Design of pipe supports & hangers.
- Stiffness & flexibility.
- Expansion & stresses.
- Line expansion & flexibility.
- Supports & anchorage of piping.
Design of pressure piping
Many decisions need be made in the design phase to achieve this successful operation, including:
- Required process fluid quantity.
- Optimum pressure-temperature.
- Piping material selection.
- Insulation selection (tracing).
- Stress & nozzle load determination.
- Pipe support standard.
The codes provide minimal assistance with any of these decisions as the codes are not design manuals.
Design of pressure components
- Pipe Structure “static” design, not Layout design.
- Limitations: Code, Pressure, Temperature, How long is the plant lifetime, What is the plant reliability, etc..
- Piping designed according to B31.3 has less lifetime than B31.1 due to lower F.S.
- Reliability of piping under B31.1 should be higher than B31.3
- Given that the code is a product of pressure technology, one of the concerns is the pressure-temperature ratings of the components.
- Each system be it vessel or piping has some base pressure-temperature rating. This is essentially the pressure temperature rating of the weakest member of the system. This can be translated that no minor component (valve, flange, etc) shall be the weakest link.
- The key components of the design conditions are the design pressure and the design temperature.
- Design pressure is defined as the most severe sustained pressure which results in the greatest component thickness and the highest component pressure rating.
- Design temperature is defined as the sustained pipe metal temperature representing the most severe conditions of coincident pressure and temperature.
- Thus we can try to simplify our stresses into two main categories;
- Pressure stress is the circumferential stress (primary stress) or hoop stress, which is known to be not self limiting.
- Temperature stress is the shear or bending stress (Secondary stress), known to be self limiting.
- In addition VIBRATION, has to be addressed as low cycle high stress named as “thermal expansion cycles”, represented by f=1 for 7000 cycles, otherwise detailed design has to be performed to prove that the pipe will withstand high cycle, low stress loads.
Design of pressure components Wall Thickness Calculation
The code assists the designer in determining adequate pipe wall thickness for a given material and design conditions as follows:
- Calculate the pressure design thickness “t”
- Add the mechanical corrosion and erosion allowances “c” to obtain the thickness tm=t+c
- Add mill tolerance (MT) to tm, then select the next commercially available wall thickness.
- Provided t

This course provides an overview of process plant piping system design. It discusses requirements contained in ASME B31.3, Process Piping, plus additional requirements and guidelines based on common industry practice. The information contained in this course is readily applicable to on-the-job applications, and prepares participants to take more extensive courses if appropriate.
What is a piping system
A piping system conveys fluid from one location to another. Within a process plant, the locations are typically one or more equipment items (e.g., pumps, pressure vessels, heat exchangers, process heaters, etc.), or individual process plants that are within the boundary of a process facility.
A piping system consists of:
- Pipe sections
- Fittings (e.g., elbows, reducers, branch connections, etc.)
- Flanges, gaskets, and bolting
- Pipe supports and restraints
Each individual component plus the overall system must be designed for the specified design conditions.
Scope of ASME B31.3
ASME B31.3 specifies the design, materials, fabrication, erection, inspection, and testing requirements for process plant piping systems. Process plants include petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related process plants and terminals.
ASME B31.3 applies to piping and piping components that are used for all fluid services, not just hydrocarbon services. These include the following:
- Raw, intermediate, and finished chemicals.
- Petroleum products.
- Gas, steam, air, and water.
- Fluidized solids.
- Cryogenic fluids.
The following are excluded from the scope of ASME B31.3:
- Piping systems for internal gauge pressures at or above zero but less than 15 psi, provided that the fluid is nonflammable, nontoxic, and not damaging to human tissue, and its design temperature is from -20°F through 366°F.
- Power boilers that are designed in accordance with the ASME Boiler and Pressure Vessel Code Section I and external boiler piping that must conform to ASME B31.1.
- Tubes, tube headers, crossovers, and manifolds that are located inside a fired heater enclosure.
- Pressure vessels, heat exchangers, pumps, compressors, and other fluid-handling or processing equipment. This includes both internal piping and connections for external piping.
