Advanced Online Condition Monitoring and Diagnostics support Operational and Maintenance Decisions in an Off-shore Gas Compression and Export System Unit

摘要

Two 3-stage reciprocating compressors are operated on an offshore platform which are in service of the Gas Compression and Export System unit. Essential information to evaluate the condition of the reciprocating compressor are a base for operation decisions, therefore an online condition monitoring system for reciprocating compressors was installed to increase the reliability and safety protection for their compressors. This paper presents several case studies about malfunctions like a broken rod, loose crosshead shoes and misalignment, as well as lessons learned which helped to reduce outage time and costs.
