Exercise: Cost-Benefit Analysis

Scenario:

A small oil and gas company needs to replace a worn-out drilling pump. They have two options:

1. Purchase a new pump: Costs $100,000 and has a lead time of 6 months.
2. Recondition a used pump: Costs $50,000 and has a lead time of 2 months.

Task:

Perform a simple cost-benefit analysis to help the company decide which option is better. Consider factors like:

• Cost savings: Calculate the difference in cost between the two options.
• Downtime: Calculate the difference in downtime for each option.
• Environmental impact: Briefly explain how each option impacts the environment.

Note: You can make assumptions about the value of lost production due to downtime.

Techniques

Reconditioned: A Second Life for Oil & Gas Equipment

Chapter 1: Techniques

Reconditioning oil and gas equipment involves a multifaceted approach tailored to the specific component and its level of degradation. The core techniques employed fall into several categories:

1. Disassembly and Inspection: This initial phase is crucial for accurate assessment. Equipment is meticulously disassembled, often using specialized tools to avoid further damage. Each component undergoes a thorough visual inspection for wear, corrosion, cracks, deformation, and other defects. Non-destructive testing (NDT) methods like ultrasonic testing (UT), magnetic particle inspection (MPI), and dye penetrant testing (PT) are frequently employed to detect hidden flaws. Detailed documentation, including photographic records, is maintained throughout the process.

2. Cleaning and Surface Preparation: Thorough cleaning is vital before any repairs. Techniques include high-pressure washing, chemical cleaning (using solvents or specialized cleaning agents), and abrasive blasting (for removing heavy corrosion or scale). The choice of method depends on the material and the type of contamination. After cleaning, surfaces often require preparation for repair or coating, potentially involving machining, grinding, or polishing to achieve a smooth, even surface.

3. Repair and Replacement: This stage addresses the identified defects. Repairs may range from simple welding or machining to more complex interventions like metallurgical repair or component rebuilding. Worn or damaged parts are either repaired using techniques like welding, brazing, or metal spraying, or replaced with new or reconditioned parts of equivalent quality. Strict adherence to original specifications or industry standards is paramount.

4. Reassembly and Testing: Components are reassembled following precise procedures, often adhering to manufacturer's guidelines or industry best practices. Careful torque control and alignment are critical for optimal performance and longevity. Rigorous testing is performed after reassembly, encompassing functionality checks, pressure tests, and performance evaluations to ensure the reconditioned equipment meets or exceeds original specifications and safety standards. This may involve running the equipment under simulated operating conditions.

Chapter 2: Models

The reconditioning process isn't a one-size-fits-all approach. Different models exist depending on the extent of damage and the desired outcome:

1. Minor Reconditioning: This involves addressing minor wear and tear, such as replacing worn seals, gaskets, or small components. It focuses on restoring functionality and preventing further deterioration. This model is suitable for equipment with minimal damage and primarily focuses on preventative maintenance.

2. Major Reconditioning: This tackles more significant damage, including substantial wear, corrosion, or component failure. It may involve extensive repairs, part replacements, and potentially the rebuilding of sub-assemblies. It aims to restore the equipment to near-new condition.

3. Overhaul: This represents the most comprehensive reconditioning model. It involves a complete disassembly, inspection, repair, or replacement of almost all components, leading to equipment that is functionally equivalent to a new unit. Overhauls are usually undertaken on critical equipment where maximum reliability and longevity are paramount.

4. Component-Specific Reconditioning: This approach focuses on specific components within a larger system. For example, reconditioning a pump, a valve, or a section of pipeline, rather than the entire assembly. This allows for targeted repairs and cost-effective maintenance.

Chapter 3: Software

Several software tools aid the reconditioning process:

1. Computer-Aided Design (CAD): Used for creating detailed drawings and models of components, aiding in the design of repairs or replacements, and ensuring accurate reassembly.

2. Computer-Aided Manufacturing (CAM): Employed in the fabrication of replacement parts or in the machining of damaged components.

3. Enterprise Resource Planning (ERP) Systems: Manage the entire reconditioning process, from initial inspection to final testing and delivery, tracking inventory, scheduling, and costs.

4. Data Acquisition and Analysis Software: Used to collect data during testing and analysis to ensure the reconditioned equipment meets performance standards.

5. NDT Software: Used in conjunction with non-destructive testing equipment to analyze results and identify defects.

Chapter 4: Best Practices

Achieving optimal results in oil & gas equipment reconditioning hinges on following best practices:

• Detailed Documentation: Maintaining complete records throughout the process, including inspection reports, repair details, and test results.
• Quality Control: Implementing rigorous quality control measures at each stage to ensure compliance with standards and specifications.
• Qualified Personnel: Employing trained and experienced personnel with expertise in oil & gas equipment repair and reconditioning.
• Use of OEM Parts or Approved Equivalents: Utilizing original equipment manufacturer (OEM) parts whenever possible or approved equivalent parts that meet the same standards.
• Adherence to Safety Regulations: Strictly adhering to all relevant safety regulations and guidelines throughout the reconditioning process.
• Preventive Maintenance: Implementing a robust preventive maintenance program to extend the life of equipment and reduce the need for major reconditioning.
• Proper Storage and Handling: Employing proper storage and handling techniques to prevent damage during the reconditioning process.
