Practical Solutions. Proven Results.
Specialized HRSG and Power Plant Consulting Services That Deliver.
A complete set of on-site and engineering services for your power generation and steam process plants.
With today’s lean staffing models, plant personnel are often stretched thin and managing multiple priorities with limited time. Sieben Power Consulting can supplement your team by deploying experienced engineers to be on site and ready to focus on critical projects and deliver timely, effective solutions. We take pride in our engineering depth and enjoy helping clients overcome persistent operational challenges. Our solutions are objective, data-driven, and calculation-based. Whether you're dealing with cycling drain pots, failed hanger restraints, steam heating (SH) and reheat (RH) drain issues, blowdown inefficiencies, or other thermal performance concerns, we’re here to help you resolve them efficiently and confidently.
HRSG Inspections & Performance Assessments
Offline Inspections
We perform comprehensive walkdowns including internal inspections (crawl spaces, boiler drums, gas path) and external casing assessments. You'll receive an on-site punch list of priority issues followed by a detailed final report with photos and recommended actions. Optional drone inspections of duct burners and roof silencers reduce access costs and improve safety.
Online Thermal Imaging
Using infrared imaging, we detect and document casing hot spots with digital/thermal photos and real-time repair advice. Final reports help you target future maintenance and outage planning effectively.
HRSG Thermal & Operational Evaluations
Low Load Operation Studies
We assess how low load conditions affect HRSG integrity. Our analysis compares real-time operating data against original design specs, identifies circulation and thermal risks, and recommends operational or equipment modifications.
Cycling Studies
Our team evaluates your startup/shutdown procedures to ensure they're minimizing damage from cycling. We'll review documentation, observe processes, and offer low-cost improvements to reduce thermal fatigue and wear.
Performance Evaluations (Including AGP Impact)
We use thermal modeling to evaluate HRSG performance under current or upgraded operating conditions (e.g. AGP, 2x1, 1x1). Final reports compare real vs. predicted performance and offer optimization steps.
Root Cause Failure Analysis
Experiencing repeated issues in the same components? We investigate underlying failure mechanisms and recommend cost-effective solutions to eliminate chronic problems.
Chemistry & FAC Consulting
Water Chemistry Assessments
We assess your chemical treatment program (AVT, phosphate, FFA), sampling methods, and procedures. Our focus: simplify operations while maintaining chemistry control during cycling.
FAC (Flow-Accelerated Corrosion) Risk Assessments
We combine hydraulic modeling, thermal data, and plant experience to identify high-risk FAC areas. Deliverables include:
Circuit-by-circuit analysis
Prioritized risk matrix
On-site marking for NDE consistency
Chemistry program review and optimization
HRSG Lifecycle Support
Long-Term Maintenance Planning
We develop an Excel-based planning tool tailored to your plant, outlining maintenance tasks, intervals, labor estimates, and cost projections to support annual outage budgeting.
HRSG Specification & Bid Evaluation
Considering a new HRSG? We review vendor specs, compare OEM risks and benefits, and help forecast 10-year O&M costs. We’ll also recommend programs to maintain asset integrity.
Design Upgrades & Replacement Solutions
We assess the impact of upgrades or retrofits on HRSG performance. As a representative of Chanute Manufacturing, we offer custom retrofit designs at wholesale pricing—bypassing OEM markups..
Specialized Inspection & Engineering Services
High Energy Piping (HEP) Programs
We inspect and evaluate HEP systems per ASME B31.1 CPC guidelines, including hot/cold walkdowns, stress analysis, and NDE guidance. Our phased approach prioritizes cost-effective, plant-specific planning and risk mitigation.
Borescope Inspections
We access hard-to-reach areas to check for FAC, cracking, or deposits—helping reduce future maintenance costs and prevent downtime.
Owner’s Engineer Support
With plant teams stretched thin, SPC can deploy focused engineering expertise to troubleshoot issues like:
Cycling drain pots
Hanger restraint failures
SH/RH drain problems
Blowdown complications
Expert Witness Services
SPC provides objective, technically sound expert witness support for legal or arbitration proceedings involving design, installation, or performance issues.
Strategic & Financial Advisory
O&M and Capital Budgeting
We leverage real-world experience managing budgets across 50+ global plants to help clients build reliable financial models and startup cost forecasts.
Plant Acquisition Due Diligence
We review inspection reports, maintenance history, and current asset conditions to support informed acquisition decisions.
