Fuels
It’s vital that fuel oil on ships are kept in prime condition, to keep engines running smoothly and efficiently, and to ensure full compliance with environmental and operational regulations.
Fuel quality matters. Protect your engine, protect your voyage.
Many onboard engine problems aren’t caused by the engine itself but by the fuel it runs on. This is the reason why fuel oil treatment is considered as core part of fuel management strategy onboard, not an afterthought.
Over the years, the quality of residual fuels used across the global fleet remains challenging and concerning. This is largely due to secondary refining, which concentrates heavier components in the fuel. The result? Poor handling, increased wear, and higher maintenance costs.
At Wilhelmsen, we help you mitigate and minimise fuel-related risks with our trusted Unitor™ FuelPower and Unitor™ DieselPower chemical solutions. Whether you're treating distillate fuels, heavy fuel oils or bio-blends, our products are developed to improve fuel stability, reduce sludge formation, and protect your engine from damage.
To support proactive maintenance and protective measurement, our fuels and lubes test kits allow you to easily check for fuel compatibility and CatFine risk, bacterial growth, saltwater or seawater contamination in fuel and lubricating oil, total iron level in cylinder oil and residual BN value in lubricating oil, amongst others.
With the right treatment and testing tools onboard, you can ensure, easy fuel management, improved engine efficiency and optimized maintenance cost

"Your Unitor™ FuelPower formula is still working wonders and except for some light dust on top, it all looks practically clean even though we lately have been using only 40% on the pump".

Why MGO management matters more than ever in the growing ECAs
As the Emission Control Areas (ECAs) expand, more vessels will need to operate on marine gas oil (MGO) or bio-MGO for extended periods. While this shift supports environmental compliance, it also introduces new operational challenges that cannot be overlooked.

Fuel oil treatment offers benefits to enhance vessel operational efficiency on road to decarbonization
With shipping currently responsible for 3% of global GHG emissions, the new EEXI and CII regulations that came into force in January comprise the IMO's short-term measures to address climate change. The aim is to reduce carbon intensity of all vessels with over 5,000 GT in international trading by 40% by 2030 and 70% by 2050 – an ambitious target for the maritime community to pursue.

Is your blended fuel compatible? Simple onboard testing explained
As VLSFO formulations vary and biofuel blends become more common, many vessels are now handling a wider range of fuel chemistries than ever before. Without a simple check up front, the first sign of trouble may be blocked filters, overloaded separators, or rising sludge volumes.

Safeguarding your fuel system
Microbial contamination: the silent threat hiding in your fuel tanks as marine fuels evolve, so do the risks. Microbial growth fueled by water ingress is quietly degrading fuel quality, threatening vessel safety, and driving up maintenance costs. In this article, Wilhelmsen experts unveil the Prevent – Test – Treat (PTT) methodology, an integrated, proactive approach to fuel management that helps you stay ahead of microbial risk. Discover how simple steps can protect your fuel, your crew, and your bottom line. Read on and contact us to safeguard your operations.

Distillate Fuel Treatment
Distillate fuels are prone to deterioration through temperature and oxidation, contamination from microorganisms and exposure to UV light - which again causes gum formation, sedimentation and colour changes. Unitor's specially designed DieselPower range is perfectly suited to resolve such common challenges for our customers.
-
Heavy Fuel Oil Treatment Chemicals
Secondary refining process has led to deterioration of residual fuels quality used by trading fleets, leading to marine HFO having heavy metals, impurities, sludge, water and ash. Unitor FuelPower range of treatment chemicals / additives have been specially formulated to tackle these challenges individually.
-
Test Kits and Reagents
It's important to test your fuel to ascertain what the problem is and the type of treatment required. Our range of test kits enable you to check for bacterial growth, sea /salt water contamination and water contamination in lubrication oil.
