Service Overview
RAM analysis quantifies key indicators such as Reliability (R), **Availability (A)**, and **Maintainability (M)** under different operating conditions, simulates potential equipment failures and maintenance plans during actual operations, identifies system bottlenecks, optimizes design schemes, and formulates rational O&M strategies. CIDIGITAL’s RAM analysis services cover the entire lifecycle, including design, evaluation, and operation optimization, meeting clients’ needs for system reliability assessments at all stages.文章源自CIDIGITAL-https://www.cidrg.cn/en/services/engineering/620.html

Case Study: RAM Analysis for a Natural Gas Processing Facility
In a large natural gas processing station project, the client required an annual system availability of over 98.5%. CIDIGITAL built a full-process RAM model, simulated system downtime under different maintenance strategies, and evaluated the redundancy configuration for key compressors and power systems. The optimized solution increased availability to 99.2% and reduced expected maintenance costs by nearly 15%.
Background
A large domestic natural gas processing station design project, with a total processing capacity of 1000×10⁴ Nm³/d, includes key units such as gas dehydration, desulfurization, condensate recovery, compression, and export. The client's project goals were:
Annual average plant availability ≥ 98.5%
Operating cycle goal: 3 years without shutdown
Achieve high reliability while controlling redundancy investment
Analysis Objectives
Perform RAM modeling analysis for the entire gas processing process
Identify critical equipment and process bottlenecks affecting availability
Optimize redundancy for major units (e.g., compressors, power systems)
Compare the impact of various maintenance strategies and resource allocations
Analysis Results & Optimization Recommendations
Configuration Scheme | Annual Availability | Estimated Downtime | Additional Investment | Remarks |
---|---|---|---|---|
Single Machine | 96.8% | 288 hours | 0 million CNY | Not meeting target |
Hot Standby | 98.7% | 113 hours | +9 million CNY | Meets requirement |
Dual Redundant | 99.4% | 52 hours | +17 million CNY | High investment |
Recommended: Hot Standby Scheme:
Add one hot standby to compressors, condensate pumps, and power systems
Optimize dehydration system maintenance windows (night/low-load hours)
Introduce CBM (Condition-Based Monitoring) for key equipment
Client Feedback & Follow-Up
Client adopted the “Hot Standby” scheme as final design recommendation
RAM results included in feasibility report and used in project review
CIDIGITAL was invited to assist with O&M strategy formulation and RAM re-evaluation
Highlights Summary
Identified bottlenecks early (compressor single-point failure impact)
Proposed cost-effective solution (1.9% availability increase, ~18 months ROI)
Provided multi-scenario charts to support efficient decision-making
