Driving cost-efficient LNG expansion through FEED verification and value engineering
Overview
As global Liquefied Natural Gas (LNG) demand continues to rise, Engineering, Procurement and Construction (EPC) companies face mounting pressure to deliver large-scale expansion projects with greater cost efficiency, faster execution and minimal operational disruption. A leading EPC Oil & Gas company, known for its expertise in LNG and major energy infrastructure projects, faced a similar challenge while preparing a competitive bid for a brownfield LNG train expansion project. Although the Front-End Engineering Design (FEED) package for the project had already been technically completed, the design still presented significant opportunities for optimization.
To strengthen its bid competitiveness and improve overall project economics, the client needed a strategic engineering partner capable of identifying practical value engineering opportunities without compromising plant safety, operational integrity or design intent. We collaborated with the EPC organization to conduct FEED verification and value engineering activities. Through a structured engineering approach and collaborative design reviews, our team of experts helped the client optimize the expansion design, reduce material quantities and improve execution efficiency enabling the client to submit a stronger and more competitive EPC bid while preserving safety, production capacity and operational integrity.
The Challenges
Why did this EPC company need to rethink a technically complete FEED design?
Executing a brownfield LNG expansion project presents unique engineering and operational complexities, particularly when modifications must be integrated into an active LNG facility without disrupting ongoing operations. Our client faced four interconnected challenges:
- FEED design optimization gap: Although the FEED package had reached technical completion and met functional and process requirements, it had not been fully optimized from a cost-efficiency and constructability perspective. Significant opportunities remained to reduce material quantities, simplify layouts and improve installation feasibility.
- Brownfield operational constraints: The brownfield nature of the project added another layer of complexity. Any modifications or equipment relocations had to carefully account for operational safety, limited space availability and integration with live LNG systems. Engineering decisions required a balanced approach that maintained operational continuity while enabling efficient expansion execution.
- Complex piping and structural environment: The project involved high piping quantities and highly congested pipe rack arrangements, which directly impacted both material costs and construction schedules. Long piping routes, structural complexity and challenging installation conditions increased the risk of schedule overruns and higher capital expenditure.
- Competitive EPC bidding environment: The client was working within a highly competitive EPC bidding environment. To improve the likelihood of winning the project, they needed to demonstrate meaningful cost optimization and execution advantages to the end customer without affecting plant capacity, safety or project objectives.
The Solution
How did we optimize the LNG expansion design?
We deployed a structured FEED verification and value engineering approach to identify optimization opportunities across plant layouts, piping systems and equipment placement for the brownfield LNG expansion project.
The engagement began with detailed engineering reviews and collaborative value engineering workshops involving multidisciplinary teams. Our team of experts conducted extensive 3D model reviews to assess piping routes, equipment positioning, structural layouts and constructability considerations within the existing plant environment.
Key highlights
- Comprehensive FEED verification to identify high-impact optimization opportunities across layout, piping and structural design
- Detailed 3D model reviews to enhance constructability and optimize installation sequencing
- Equipment relocation studies to minimize piping lengths and eliminate design congestion
- Pipe rack optimization to streamline routing and improve accessibility
- Identification and validation of value engineering opportunities without compromising project intent, safety or operational integrity
- Brownfield-focused engineering assessments to ensure seamless integration with live LNG operations
- Collaborative engineering workshops to align optimization strategies with project objectives and bid requirements
Our engineering teams worked closely with the client to rigorously validate every recommendation against operational, safety and execution constraints. The optimized design preserved the original project intent and production capacity, while delivering measurable improvements in project economics and construction feasibility.

Road Ahead
Why early FEED optimization is becoming a competitive advantage in LNG expansion?
The value engineering framework established during this engagement can be scaled across future LNG expansions and similar brownfield energy infrastructure projects. By embedding FEED verification and constructability optimization earlier in the project lifecycle, organizations can enhance project economics, mitigate execution risks and accelerate delivery timelines for complex energy projects.
For LNG operators and EPC companies facing rising cost pressure, competitive advantage is no longer defined by a technically complete FEED, but by how intelligently it is optimized. With the right engineering partner, FEED verification can become a powerful lever for cost efficiency, constructability and bid differentiation.
Frequently Asked Questions
What is FEED verification in LNG projects?
FEED verification is the structured review of a Front-End Engineering Design package to confirm that the design meets technical, operational, safety and project requirements. In this engagement, our team went further by identifying opportunities to improve cost efficiency, constructability and bid competitiveness.
How does value engineering reduce LNG project costs?
Value engineering reduces project costs by identifying practical ways to simplify layouts, reduce material quantities, shorten piping routes, optimize equipment placement and improve constructability. The focus is on lowering cost without compromising safety, design intent or operational performance.
Why is brownfield LNG expansion challenging?
Brownfield LNG expansion is complex because new equipment, piping and structures must integrate seamlessly intoan existing operating facility. Engineering teams must work around live systems, space constraints, safety requirements and operational continuity while maintaining operational continuity and driving stronger project economics.
How can EPC companies strengthen competitive bids for LNG expansion projects?
EPC companies can strengthen bids by demonstrating validated cost optimization, improved constructability and reduced execution risk. FEED verification and value engineering deliver evidence-backed improvements that differentiate a bid without compromising plant capacity or overall project objectives.
What role does 3D model review play in constructability optimization?
3D model review helps engineering teams visualize congestion, assess access limitations, evaluate piping routes, identify installation challenges and validate equipment placement before construction begins. This reduces rework risk and improves execution readiness.
What outcomes can energy companies expect from FEED verification and value engineering?
Energy companies can expect reduced piping and structural material take-offs, lower capital expenditure, enhanced constructability, simplified layouts, reduced execution complexity and greater confidence in project delivery planning.
