Fuel Line
Reliable engine protection as fuels change
Fuel oil today is more complex than ever. The challenges created by very-low-sulphur and ultra-low-sulphur fuel oil (VLSFO/ULSFO) remain, even long after the regulatory shift of 2020. Biofuel blends – which will soon be a practical necessity to meet CII targets – only add to the difficulties.
Cat fines are an ever-present threat in residual oil, even when biofuels are mixed in. Add that biofuel blends can be unstable and cause incompatibilities between fuels. Or the fact that they degrade faster and have sensitive cold flow properties.
Whatever the fuel blend, it’s critical to prepare it in an optimal way for the engine. Alfa Laval has the full range of equipment and the knowledge to make it work together. The Alfa Laval Adaptive Fuel Line handles all fuels and biofuels defined in the ISO8217:2024 standard, along with their many complexities.
The Alfa Laval Adaptive Fuel Line
The Alfa Laval Adaptive Fuel Line covers separation, feed synchronization, filtration, temperature control, fuel conditioning and more. Each equipment solution has its own duty. But together they form a single, flexible process that responds to changes and challenges in real time – strengthened by Alfa Laval knowledge and service.
Adaptiveness is readiness – and using less
Fuel oil composition is constantly changing. Each bunker, each blend can be different, even when the specifications are the same. Likewise, your engine’s needs vary with your sailing speed. For complete and efficient engine protection, your fuel line must adapt to the challenges and demands.
As a complete process solution, the Alfa Laval Adaptive Fuel Line:
- Reduces oil losses and sludge production for all fuel and biofuel blends
- Synchronizes the fuel feed to actual engine consumption
- Enhances cat fine removal by optimizing separation conditions
- Saves energy by minimizing return flow and re-separation of cleaned fuel
- Delivers correct fuel parameters – even during changeover between blends

The Alfa Laval Adaptive Fuel Line turns individual equipment solutions into an even stronger whole. Our blue book explains the parts and how they work together.

Maritimt biodrivstoff
Marine biodrivstoff som HVO og FAME kan brukes i dieselmotorer uten store motormodifikasjoner. De har en positiv innvirkning på et fartøys CO2-fotavtrykk, men egenskapene deres skiller seg fra konvensjonelle oljer – så de må håndteres nøye. Med dyp innsikt og bransjens første biodrivstoff-klare separatorer, kan Alfa Laval hjelpe deg med vellykket overgang til biodrivstoff.

The escalating battle against cat fines
For at least half a century, shipowners and operators have been fighting off cat fines. The threat from these highly damaging particles has grown in recent years, which means engines today need more sophisticated defence.
The cat fine problem – origins and risks
Catalytic cracking lets refiners extract more from crude oil, but shipowners and operators are left to clean up the mess. If the cat fines left in marine fuel oil get into the engine, they have a devastating and costly effect – which may include catastrophic damage.
Why “better” fuels have been worse for the engine
The shift to VLSFO/ULSFO was driven by global regulation with emissions in focus. While better from an emissions perspective, these fuels have hardly been better for engine operations. Cat fines have increased – and mixing in biofuels won’t resolve the issues.
Integrating cat fine defence
Effective fuel line equipment is critical in protecting the engine from cat fines, but even more is required. From the design of the fuel line as an integrated process to factors such as maintenance, monitoring and service, knowledge plays a vital role in engine protection.

Use slow steaming to boost cat fine protection
Operating at reduced speed is a more common strategy than ever. It reduces fuel consumption and emissions, but it can also be a significant advantage in the fight against cat fines. By matching fuel line operations to the engine’s actual fuel consumption, flow synchronization optimizes engine protection – removing more cat fines and saving energy in the process.

Understand the ALCAP advantage
ALCAP™ technology revolutionized fuel oil separators, making separation an adaptive process. Whereas traditional separators needed manual adjustment for every fuel type, ALCAP separators adjust automatically to provide uninterrupted operation. Learn how their ALCAP function maximizes separation efficiency, fuel economy and engine protection.
Våre produkter
S og P Flex
Alfa Laval S og P Flex-serien av separatorer er ideelle for alle drivstoff- og smøreoljer. Maksimer beskyttelsen og effektiviteten ved å skape et modulært separatorsystem som er spesifikt for ditt anvendelsesområde. Velg mellom den avanserte S-separatoren, verdens mest solgte separator for drivstoff- og smøreolje, eller enkelheten til P-separatoren.
FlowSync
Alfa Laval FlowSync er et automatisk kontrollsystem for separatorpumper til bruk i fartøyets behandlingssystem. Den synkroniserer drivstoffstrømmen til separatoren baseres på faktisk forbruk – noe som gir deg bedre motorbeskyttelse, lavere nivåer av katalysatorpartikler (cat fines) og reduserte energikostnader.
Fuel Conditioning Modules, olje
FCM One Oil er designet for konvensjonelle marineoljeoljer, men mer enn oppfyller samsvarskravene til drivstoff når det gjelder renhet, trykk, temperatur, viskositet og strømningshastighet i henhold til motorspesifikasjoner. Det kan også konfigureres til å håndtere flere typer drivstoff, produsere drivstoffblandinger og håndtere den automatiske overgangen mellom dem.
AlfaNovaM heater
The Alfa Laval AlfaNovaM heater is a heat exchanger made of 100% stainless steel, bonded without any copper or nickel. With this unique construction, the compactly designed heater is a perfect choice – not only for fuel and lubricating oils but also for biofuels.
ALP tre-skruepumper
Alfa Lavals ALP tre-skruepumper er utviklet for lavest mulige driftskostnader og maksimal pålitelighet med spesifikt fokus på skipsfartsindustrien. ALP er det åpenbare valget for håndtering av drivstoff og smøreoljer.

Alfa Lavals 290-filtre sørger for finfiltrering nesten uten trykkfall. De er egnet til en rekke bruksområder, for eksempel filtrering av smøreolje for firetaktsmotorer og filtrering av hydraulisk styreolje for totaktsmotorer. Filtrene kan fås med forskjellige slamfjerningsenheter, for eksempel et avledningskammer eller Eliminator-kombinasjon.
Viscochief III
Alfa Laval Viscochief III provides updated process control functions to those fuel supply systems designed before the introduction of the marine fuels currently in use. Viscochief III allows full process automation and extended remote monitoring and control. By upgrading the existing fuel supply system on board with Viscochief III, the conditions of any fuel at the engine battery limit will be automatically and safely secured.
