Global Boiler Services
Reliable boiler solutions for LNG carriers and large tankers
LNG vessels operate under extreme thermal and operational demands, making boiler reliability essential for safe cargo handling, fuel conditioning, and efficient vessel performance. At Global Boiler Services we deliver Class-approved boiler repair, retrofit, and maintenance solutions tailored to the unique requirements of LNG carriers and large tankers.
With repair squads based in Denmark, Dubai, and Singapore, and more than 1,000 boiler repairs completed worldwide — including over 100 on-voyage repairs — we ensure fast responses, high-quality workmanship, and minimal downtime.
LNG vessel boiler maintenance
Steam boilers on LNG carriers are exposed to high operating cycles, fluctuating loads and demanding fuel systems. Our teams carry out complete steam boiler maintenance for LNG vessels, including:
• inspection, fault diagnostics and damage assessment
• repair of pressure parts, tubes, headers and refractory
• burner service, tuning and fuel system adjustments
• Class-approved welding and materials testing
• on-voyage maintenance to minimise downtime
Our main workshop in Denmark is certified by DNV, Lloyds Register, RINA, ISO and BV, ensuring every repair is delivered to OEM standards.
LNG ship boiler retrofit
As LNG fleets transition to new operating profiles, many vessels require retrofit solutions to upgrade ageing boiler systems. We offer:
• boiler tube and membrane wall renewal
• replacement of obsolete components and assemblies
• retrofit of burners and control systems
• structural boiler upgrades for extended service life
• Class documentation and full commissioning support
Experienced welders and boiler engineers carry out our LNG boiler retrofit services with deep knowledge of Kawasaki, Mitsubishi, Kangrim, Aalborg/Alfa Laval, Foster Wheeler, Hitachi and Hyundai boiler designs.
LNG fuel system service
Efficient fuel handling is critical on LNG vessels — especially when switching between boil-off gas (BOG), MGO and other fuels. We support operators with:
• burner and fuel train inspection
• adjustment of atomising systems and controls
• service of ignition systems and safety devices
• troubleshooting of combustion performance
• calibration and tuning for stable LNG-adapted operation
Our automation specialists ensure that fuel-air balance, safety interlocks and burner performance remain fully optimised.
LNG-ready boiler systems
For owners preparing vessels for LNG operations or hybrid fuel scenarios, we provide solutions that ensure boilers remain safe, stable and fuel-efficient:
• upgrades making oil-fired boilers “LNG ready”
• adaptation for low-flashpoint fuel environments
• enhanced monitoring and control systems
• thermal and structural reinforcement for high-duty cycles
Global Boiler Services works closely with shipowners to define the right system adjustments for current and future operational needs
Marine boiler solutions for LNG ships
Our services support every stage of LNG boiler lifecycle management — from emergency repair to planned upgrades:
• emergency riding crews for rapid deployment
• complete boiler rebuilds on LNG steam vessels
• OEM-quality component fabrication in our Danish workshop
• on-voyage boiler repair to reduce time off-hire
• full compliance with Class standards and documentation
Many of the world’s largest LNG and tanker operators choose Global Boiler Services as their preferred partner for boiler repair.
