POSITION SUMMARY Lauren Services is seeking a highly experienced and technically strong Rotating Equipment Subject Matter Expert (SME) to provide technical leadership for major rotating equipment on EPC and EPCM projects in the Oil & Gas and Energy sectors. The role is responsible for the selection, specification, procurement, vendor coordination, design integration, and implementation of gas turbine-driven compression systems, centrifugal compressors, and large pump systems across Greenfield and Brownfield facilities. The successful candidate will act as a technical authority throughout the equipment lifecycle, ensuring the machinery package and associated systems operate safely, reliably, and effectively within the overall facility, not solely within the vendor package boundary. DUTIES AND RESPONSIBILITIES Technical Leadership and Equipment Design Serve as technical authority during concept selection, FEED, detailed design, procurement, construction, commissioning, and startup. Lead selection, sizing, specification, and technical evaluation of gas turbines, centrifugal compressors, process compressors, and large pump systems. Provide specialist input for gas turbine packages of approximately 20,000 HP or greater and large pumps typically ranging from 2,000 to 6,000 HP. Assess operating philosophy, performance, reliability, maintainability, availability, and lifecycle requirements. Turbine and Compressor Systems Provide demonstrable expertise with Solar Turbines and/or Baker Hughes gas turbines and natural gas compressor packages. Engineer and review centrifugal compressor operating envelopes, performance curves, surge margins, capacity control, anti-surge protection, recycling systems, and recycle valve sizing. Evaluate startup, shutdown, settle-out, turndown, transient operation, and interaction with upstream and downstream facilities. Vendor Packages and Procurement Prepare and review data sheets, specifications, material requisitions, purchasing packages, technical bid evaluations, and vendor document requirements. Lead technical clarification meetings, design reviews, and resolution of vendor technical queries. Review P&IDs, general arrangements, performance curves, mechanical details, control narratives, cause-and-effect documentation, and package interfaces. Coordinate process, piping, mechanical, controls, electrical, structural, building, and safety interfaces. Associated Systems and Facility Integration Provide oversight for air intake and filtration, fuel gas, lube oil, seal, cooling, exhaust, ventilation, acoustic, utility, and machinery protection systems. Review package controls, vibration monitoring, shutdown logic, fire and gas detection, and fire suppression systems. Advise compressor buildings, access, lifting and maintenance requirements, ventilation, hazardous areas, piping arrangements, valve sizing, and relief/de-pressuring interfaces. Large Pump Systems Provide specialist support for large crude oil, pipeline, booster, transfer, and process pumps. Review hydraulic performance, operating range, driver sizing, minimum-flow protection, controls, and system integration. Support troubleshooting, debottlenecking, reliability improvement, and performance optimization. Construction, Commissioning, and Operations Support Participate in vendor inspections, FATs, SATs, installation reviews, pre-commissioning, commis…
