Dual Fuel Marine Boiler for LNG Carriers – Reliable Power on the High Seas
Our dual fuel marine boiler for LNG carriers delivers consistent steam generation while running on either low‑sulfur marine diesel oil (MDO) or liquefied natural gas (LNG). Designed for the rigorous demands of long‑haul shipping, the unit combines compact geometry with a robust heat‑exchange core, enabling ship‑owners to meet emission caps, optimise fuel costs, and maintain continuous operation during port stays or at sea. Engineered to integrate seamlessly with existing cargo‑handling and auxiliary‑system layouts, the boiler supports a wide range of steam loads—from 2 t/h up to 12 t/h—making it a versatile choice for new builds and retro‑fits alike.
Why Our Boiler Stands Out
- True Dual‑Fuel Flexibility: Automatic fuel switching ensures uninterrupted steam production when LNG supply fluctuates or when regulatory zones require marine diesel.
- Low NOx & SOx Emissions: Optimised combustion chambers meet IMO Tier III standards, reducing nitrogen oxides by up to 90 % compared with conventional oil‑only boilers.
- Space‑Saving Design: A 30 % reduction in footprint versus legacy models frees valuable cargo‑bay volume for additional LNG tanks or equipment.
- Extended Duty Cycle: Certified for 24/7 operation with a minimum 90 % load‑following capability, ideal for carriers that experience variable steam demand.
- Maintenance‑Friendly Layout: Modular heat‑exchange plates and quick‑release fuel valves cut planned‑maintenance downtime by up to 40 %.
Typical Specifications (customizable per order)
| Parameter | Range | Unit |
|---|---|---|

| Fuel Flexibility | LNG / MDO (≤0.5 % S) | – |
| Thermal Efficiency (LNG) | ≥ 92 | % |
| Thermal Efficiency (MDO) | ≥ 88 | % |
| Dimensions (L×W×H) | 2.5 – 5.0 m × 1.8 – 3.0 m × 2.0 – 3.5 m | m |
| Weight (incl. accessories) | 12 – 28 | t |

All values are typical; exact numbers are defined during the engineering phase to match vessel‑specific requirements.
Where the Boiler Adds Value
Long‑Distance LNG Trade Routes: On voyages that cross emission‑controlled zones (e.g., North Sea, Baltic), the ability to switch to LNG eliminates costly fuel surcharges while keeping steam availability for cargo heating and cargo‑tank cleaning.
Port‑Side Operations: During berth, many terminals restrict exhaust emissions. Running on LNG at the dock maintains compliance and avoids penalties.
Retrofit Projects: For existing carriers, the compact dual‑fuel boiler can be installed within the original boiler‑room envelope, avoiding major structural modifications and shortening the conversion schedule.
FAQ – Quick Reference for Procurement Teams
What is the minimum order quantity (MOQ) for a custom‑spec dual fuel marine boiler?
We accept single‑unit orders for both new‑build and retrofit projects. Volume discounts apply from the second unit onward.
Can the boiler be adapted to a specific ship’s layout?
Yes. Our engineering team works with shipyards to tailor dimensions, mounting points, and control‑system interfaces to the vessel’s existing infrastructure.
What is the typical lead time from order confirmation to delivery?
Standard lead time is 30‑45 days for standard configurations; highly customised solutions may require 60‑90 days, depending on component availability.
What warranty and after‑sales support are provided?
All units carry a 24‑month parts‑and‑labour warranty, plus optional extended service contracts covering on‑site spares and remote diagnostics.
