Onshore power-plant consultancy.

Onshore Gas Engine & Dual-Fuel Generator Systems We Support

Onshore power plants operating medium-speed Dual-fuel and pure spark gas engine generating sets face tight availability targets, grid-code frequency requirements and compressed outage windows. Our consultancy supports plant managers and engineering teams across three core technical areas:

• Base-load & peaking spark gas engine generator sets: Reviewing high-energy ignition coils and spark plugs, pre-chamber gas valve timing, cylinder-by-cylinder knock detection and misfire margins, exhaust gas temperature spreads, and air-fuel ratio / natural gas engine governor droop and isochronous load-sharing stability.
• Dual-fuel power plant fuel-flexibility & backup diesel switching: Evaluating main gas admission valve (SOGAV) response, micropilot fuel injection nozzle condition, common-rail pilot fuel pressure stability, Gas Valve Unit (GVU) pressure regulation, and seamless gas-to-diesel or diesel-to-gas fuel transfers during pipeline gas quality shifts or grid disturbances.
• Planned outage, top-end & major overhaul engineering: Scoping running-hour maintenance worklists, cylinder head and exhaust valve seat wear assessments, liner honing and piston-ring inspection criteria, turbocharger and charge-air cooler performance checks, and critical-path readiness before a scheduled plant outage.

Keep the review connected to plant operations and maintenance.

A technical issue at a gas engine power plant can involve equipment condition, operating history and maintenance records and the demands placed on the facility. Whether your plant operates Dual-fuel gas engine generators or pure spark gas engines, the initial discussion establishes what is known, what remains uncertain and which decision the plant team needs to make.

For an agreed consultancy assignment, we review the relevant operating parameters—such as ignition stability, cylinder-by-cylinder knocking or misfire alerts, natural gas engine governor and load-sharing response, fuel-gas supply pressure, and top-end or major overhaul intervals—and agree the form of the recommendations with your team. Describe recurring concerns, current constraints and any planned outage window so the review can be scoped around the actual situation.

Agree the output before work begins.

A useful brief names the question, the equipment or process involved, the intended audience and the target date. It also identifies who can provide operating and maintenance information and who will review the recommendations. We use that brief to agree the work and its limits with you.
