Engineering Cost Estimates: The Foundation of Oil & Gas Project Success

In the dynamic and demanding world of Oil & Gas, success hinges on meticulous planning and accurate financial forecasting. One crucial element in this equation is the Engineering Cost Estimate, a vital tool for project stakeholders to understand the financial implications of development and ensure resource allocation aligns with project goals.

Defining the Engineering Cost Estimate:

An Engineering Cost Estimate, in essence, is a detailed financial prediction for an Oil & Gas project. It goes beyond a simple guesstimate, relying on a rigorous process of breaking down the project into individual work packages and analyzing their associated costs. These packages encompass everything from construction and equipment to labor, materials, and overheads.

The Process of Building a Robust Estimate:

Developing a comprehensive Engineering Cost Estimate involves:

Detailed Work Breakdown Structure: The project is dissected into manageable work packages, each with specific tasks, timelines, and resource requirements.
Cost Analysis: Each work package undergoes a thorough cost analysis, considering factors like:
- Labor: Skilled labor costs, including wages, benefits, and training.
- Materials: Cost of equipment, supplies, and consumables.
- Subcontractor Costs: Expenses incurred from engaging external specialists.
- Overhead: Administrative, insurance, and other indirect costs.
Burden Allocation: Appropriate burdens, such as profit margins, contingency funds, and risk assessments, are added to the individual work package costs.

Who Creates the Estimate?:

The responsibility for creating Engineering Cost Estimates often lies with:

Contractors: Experienced cost analysts within contracting firms meticulously analyze the project scope and break down costs to ensure accurate bids.
Price Analysts: These professionals, often within oil companies, analyze market trends and vendor pricing to ensure competitive bids and fair compensation.
Cost Accountants: Cost accountants play a crucial role in ensuring financial accuracy, tracking expenses against the estimates, and identifying potential cost overruns.

Beyond Numbers:

While the Engineering Cost Estimate is rooted in numbers, its true value lies in its ability to inform crucial decisions:

Project Feasibility: An accurate estimate helps stakeholders assess project viability and financial feasibility before committing resources.
Budget Allocation: The estimate provides a clear roadmap for budget allocation, ensuring that funds are used effectively across various project phases.
Risk Management: Contingency funds within the estimate help mitigate unforeseen risks and provide financial flexibility during project execution.

Conclusion:

The Engineering Cost Estimate is a cornerstone of successful Oil & Gas projects. By meticulously analyzing costs, incorporating essential burdens, and leveraging expertise across various disciplines, this crucial tool empowers stakeholders to make informed decisions, manage risks, and ultimately, achieve project success.

Answer

Engineering Cost Estimates Exercise

Scenario: You are a cost analyst for an oil company planning to build a new offshore drilling platform. You have been tasked with developing an initial Engineering Cost Estimate for the project.

Task:

Identify at least 5 major work packages required for the construction of the platform.
For each work package, list 3 potential cost factors that you would need to consider in your estimate.
Explain how you would approach allocating burdens (profit margins, contingency funds, and risk assessments) to your estimated costs.

Exercise Correction

This is a sample solution, your specific work packages and cost factors may vary depending on the project specifics.

1. Major Work Packages:

Platform Design and Engineering: Covers all the technical plans and specifications for the platform.
Materials Procurement: Includes sourcing and purchasing all necessary materials, equipment, and components.
Construction: The actual building of the platform, including all labor and specialized equipment.
Installation: The process of transporting and setting the platform in its designated location.
Commissioning and Testing: Ensuring the platform is fully operational and meets safety standards.

2. Cost Factors per Work Package:

Platform Design and Engineering:
- Engineering labor costs (salaries, benefits)
- Software and licensing fees for design tools
- Consulting fees for specialized engineering expertise
Materials Procurement:
- Material costs (steel, concrete, specialized equipment)
- Shipping and transportation costs
- Customs duties and taxes
Construction:
- Construction labor costs (wages, benefits, safety training)
- Rental costs for specialized equipment (cranes, welding machinery)
- Insurance and safety measures
Installation:
- Transportation costs (barges, specialized vessels)
- Installation labor costs (specialized crews)
- Marine survey and environmental impact assessment costs
Commissioning and Testing:
- Testing equipment and labor costs
- Certification and inspection fees
- Finalization of documentation and handover procedures

3. Burden Allocation:

Profit Margins: This would be determined based on industry standards and the company's desired profit margin. It would be applied as a percentage markup on the estimated direct costs of each work package.
Contingency Funds: These would be allocated based on risk assessments for each work package. Higher-risk packages might receive a higher percentage of contingency funds.
Risk Assessments: This involves identifying potential risks for each work package, estimating their potential impact on costs, and allocating funds to mitigate those risks.

Remember: This is a simplified example, and a real-world Engineering Cost Estimate would involve a more detailed analysis of each work package and cost factor. You would also need to consider market conditions, inflation, and potential changes in project scope.
