ecoFGSS®

The fuel is already onboard

For an LPG carrier, the cargo can also become part of the vessel’s propulsion strategy. ecoFGSS® conditions LPG from storage and delivers it safely and reliably to the dual-fuel engine, cutting conventional marine-fuel use while integrating cargo handling and fuel supply as one gas system.

Changing the fuel changes more than the engine

Using LPG as fuel creates a critical interface between cargo storage, fuel conditioning and propulsion. The fuel has to be drawn from storage, conditioned to the pressure and temperature the engine needs, and supplied continuously as load and conditions change, all while the cargo handling system keeps doing its own job safely.

Design cargo and fuel systems independently and you create extra interfaces between equipment, control philosophies, suppliers and responsibilities. The challenge is not simply getting LPG to the engine. It’s making cargo, fuel, and propulsion work together reliably.

Engineer cargo and fuel as one system

ecoFGSS® applies Babcock LGE’s gas-handling engineering to the complete route from LPG storage to the engine interface. When the cargo handling system and fuel gas supply system come from one source, the architecture can share design philosophy and common equipment, rather than reconciling two independently designed packages later.

Fewer interfaces. Common engineering. One provider.

Use the cargo as fuel. Reduce the emissions burden.

LPG carriers already carry LPG at scale. ecoFGSS® lets that cargo be used as propulsion fuel instead of relying solely on conventional oil-based marine fuels. Against those fuels, LPG can materially reduce sulphur oxide and particulate emissions and can lower tank-to-wake CO₂ intensity, with the precise benefit depending on LPG composition, engine efficiency, pilot-fuel use and operating profile.

The environmental benefit starts with the fuel. ecoFGSS® makes that fuel practical to use.

Integration removes complexity before it reaches the vessel

Fewer interfaces

Cargo handling and fuel supply engineered together, reducing boundaries between storage, conditioning, controls and propulsion.

Common equipment

Greater equipment and spares commonality can simplify maintenance, inventory and crew familiarity.

Aligned design philosophy

Consistent engineering decisions across cargo and fuel, rather than reconciling two separate packages at the vessel interface.

One design authority

Clearer responsibility through integration, commissioning and gas trials, with fewer ambiguous system boundaries.

Complexity removed in design is complexity the vessel does not have to manage in service.

Reliable fuel without unnecessary crew intervention

Fuel availability is propulsion availability. ecoFGSS® is designed around continuous, reliable LPG supply while minimising manual intervention, conditioning the fuel as engine demand changes so the vessel can use LPG without making routine operation labour-intensive.

The system should manage the fuel, so the crew can operate the vessel.

Matched to the vessel, not forced into one arrangement

Low-pressure pumps

Available for deck tank and cargo tank solutions.

Multiple vessel arrangements

The architecture is matched to the vessel, rather than forcing every application into one equipment set.

Suitable for newbuild and retrofit

One system decision. Benefits across the vessel

Fuel

Use LPG already carried onboard as an alternative to conventional marine fuel.

Emissions

Reduce conventional-fuel emissions exposure, including sulphur and particulates, with potential tank-to-wake CO₂ benefit.

Integration

Reduce interfaces and align cargo handling and fuel supply around common engineering, equipment and responsibility.

Fuel transition, emissions and integration are not separate problems. On an LPG carrier, they are part of the same system.

Proof

First to market and proven on the LPG dual-fuel fleet

Read the case study.

The strongest proof is not a system count. It is that integrated cargo handling and fuel supply has moved from a first-of-its-kind application into repeated fleet deployment.

Platform evolution

Proven LPG engineering

Extended for the next fuel

The engineering established through ecoFGSS® also underpins Babcock LGE’s development of an ammonia fuel gas supply system. ecoFGSS-FLEX® extends the proven fuel-system philosophy into ammonia, where fuel conditioning, safety, release management and system integration become even more demanding.

Through-life support

Fuel system confidence has to last beyond delivery

The fuel gas supply system sits directly in the vessel’s propulsion chain. Babcock LGE supports its systems through engineering support, training, spares and in-service assistance, and where cargo and fuel are delivered together, that relationship extends across the integrated gas system rather than stopping at an equipment boundary.

LPG · FUEL GAS SUPPLY SYSTEM

Cargo and fuel. Engineered as one.

The question is not simply whether LPG can be delivered to the engine. It’s whether the vessel can use the cargo as fuel, cut its emissions exposure and integrate cargo, fuel and propulsion without unnecessary complexity.
