Dual‑Fuel LNG & Marine Gas Oil Boiler – Reliable Power for Shipping & Offshore
The dual fuel lng and marine gas oil boiler delivers continuous steam and hot water on vessels, offshore platforms, and port facilities where fuel flexibility is a strategic advantage. Engineered for the harsh marine environment, it can switch seamlessly between liquefied natural gas (LNG) and marine gas oil (MGO) without compromising efficiency or emissions compliance. Our boiler line meets IMO Tier III standards, reduces operating costs, and extends the range of any marine power plant.
Where It Performs Best
Shipping operators, offshore drilling contractors, and port authorities choose this boiler for three core scenarios:
- Vessels that must meet strict NOx limits while retaining the option to run on cheaper LNG when it is available.
- Offshore platforms requiring a compact, low‑maintenance steam source for process heating and fuel‑gas generation.
- Coastal terminals that need a dependable hot‑water system for cargo handling and tank cleaning, with the flexibility to use local MGO during LNG supply interruptions.
How It Works – Seamless Fuel Transition
The boiler incorporates a dual‑combustion chamber equipped with an electronic fuel‑selector valve. When LNG pressure falls below a preset threshold, the controller automatically opens the MGO line, ignites the secondary burner, and stabilises output within seconds. Real‑time monitoring of flame temperature, exhaust oxygen, and emissions ensures optimal combustion regardless of the fuel mix. The system also integrates with vessel automation platforms via Modbus/TCP, allowing remote diagnostics and predictive maintenance.
Typical Specifications (customizable per order)

Competitive Edge – Why Our Boiler Stands Out
• Fuel flexibility without performance loss – identical steam output whether running on LNG or MGO.
• Reduced emissions – meets IMO Tier III NOx limits and qualifies for Green Shipping incentives.
• Compact footprint – engineered for tight engine‑room spaces, saving up to 30 % volume compared with conventional single‑fuel units.
• Extended service life – marine‑grade stainless steel and corrosion‑resistant coatings guarantee 15+ years in salt‑water environments.
• OEM & ODM support – we can integrate custom control panels, specific pressure‑ratio sensors, or alternative mounting configurations to match your vessel’s design documentation.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑engineered boiler?
We accept orders as low as a single unit for prototype or pilot projects. Larger series production (10 + units) benefits from volume discounts and streamlined lead times.
Can the boiler be adapted to a specific ship‑board control system?
Yes. Our engineering team provides hardware and software interfaces for DNV‑GL, NMEA‑2000, or proprietary SCADA platforms. We also offer firmware customization to match your vessel’s automation protocols.
What is the typical lead time from order to delivery?
Standard models ship within 15‑30 days after order confirmation. Fully customized configurations require 30‑45 days, depending on the complexity of the control‑system integration and material approvals.
What warranty and after‑sales support are provided?
All units come with a 24‑month warranty covering manufacturing defects and performance guarantees. Our global service network offers on‑site commissioning, routine maintenance contracts, and spare‑parts logistics in major ports worldwide.
