System Composition
Core Gas Turbine Unit
- Aero‑derivative gas turbine core with high energy‑density design
- Dual‑fuel combustion chamber for natural gas and diesel switch‑over
- Robust material configuration adapted to offshore salt‑fog corrosion environment
Full Skid‑Mounted Auxiliary Package
- Intake air filtration & silencer system
- Lube‑oil air‑cooled radiator assembly
- High‑efficiency synchronous generator set
- Complete dual‑fuel supply & safety shut‑off system
- Intelligent PLC control, protection & monitoring cabinet

Core Advantages
- High Energy Density: Compact layout, high shaft output power for limited‑space offshore and skid‑mount scenarios.
- Dual‑Fuel Flexibility: Seamless operation on natural gas or diesel, improves site fuel availability.
- Excellent Offshore Adaptability: Optimized for salt‑fog coastal & offshore working conditions.
- High‑Quality Waste‑Heat: High exhaust temperature, perfect for CCHP combined cooling‑heating‑power projects.
- 20,000‑Hour Runtime: Mature hot‑section design for long continuous operating cycle.
Important Considerations
- Low‑emission NOₓ ≤25 mg/m³ variant is still under technical development, not commercially available yet.
- Performance data is based on ISO natural‑gas condition; output will vary with ambient temperature, altitude and fuel quality.
- Offshore deployment requires extra anti‑corrosion coating and filter customization as project scope.
- Hot‑section components require scheduled professional inspection and overhaul upon 20000‑hour cycle.
- For export projects, local regulatory & certification work shall be implemented as project‑customized scope.
Typical Application Scenarios
- Offshore Oil & Gas Platform: Reliable prime power supply for offshore drilling & production facilities, salt‑fog resistant customized package supported.
- Distributed Energy & CCHP: Combined cooling‑heating‑power system, recover high‑temperature exhaust waste heat to raise comprehensive energy efficiency.

Frequently Asked Questions
Q1: What fuels does this 7 MW gas turbine genset support?
Standard unit supports dual‑fuel: natural gas and diesel. Fuel switching needs to be operated under specified working conditions. Other special fuels require project‑oriented customization.
Q2: Is the low‑emission NOₓ ≤25 mg/m³ version ready for order?
The low‑emission variant is currently under development. It is not commercially available at present. Please contact our sales team for the latest R&D progress.
Q3: Can this unit be used on offshore oil‑gas platforms?
Yes. It has inherent offshore‑adapted design. Additional salt‑fog anti‑corrosion coating, special air intake filter and marine‑grade component upgrade need to be included in the project scope for real offshore deployment.
Q4: What does the 20000‑hour single‑unit runtime mean?
It is the designed hot‑section operating interval. After accumulating 20,000 operating hours, the gas turbine hot‑section parts need professional inspection and overhaul service to restore performance and reliability.
Q5: Can it be configured for mobile truck‑mounted power vehicle?
Yes. It can be designed as truck‑mounted mobile power solution. Chassis, vibration isolation and space layout need re‑engineering for mobile application, which belongs to customized project work.
