Fuel Treatment for Peak Performance and Regulatory Compliance

Maintaining optimal fuel oil quality on ships is crucial for smooth engine operation and regulatory compliance. Many onboard issues stem from the quality of fuels rather than engine malfunction, highlighting the importance of integrating fuel treatment into routine maintenance.

Over time, the quality of residual fuels has degraded due to secondary refining, which concentrates heavier elements, increasing maintenance needs and costs. Our FuelPower™ and DieselPower™ solutions address these challenges for both distillate and heavy fuel oil, while our fuel test kits detect bacterial growth, saltwater contamination, and other fuel impurities.

Dieselpower CFPP

Our DieselPower CFPP additive is engineered to tackle winter fuel challenges, lowering the Cold Filter Plug Point (CFPP) to -25°C for better fuel flow. This solution offers multiple advantages, including preventing wax buildup that can block fuel systems, reducing wax particle size, and avoiding power loss by maintaining cold flow properties. The WASA additive prevents wax from settling in tanks, ensuring consistent fuel quality. With round-the-clock support, our additive ensures your fuel remains efficient even in freezing conditions.

Challenges with Cold Temperatures

Is your onboard fuel ready for harsh conditions?

• ISO 8217 specifies a Pour Point of -6°C for fuel solidification but overlooks the Cold Filter Plug Point (CFPP), where issues can arise as high as 15°C.
• Wax formation can clog filters, purifiers, and pipelines when temperatures near CFPP, even in summer-bunkered diesel used in colder regions.

Challenges with Wax in Fuel

• Wax buildup can block fuel systems, leading to power loss.
• Temperatures above 15°C may still cause waxing.
• This results in unscheduled maintenance and, in severe cases, unusable fuel.

Fuelpower Soot Remover Liquid Plus

Extensive Yearlong Trials on MV Tonsberg

Tests on the 76,500 GRT Ro-Ro vessel powered by a MAN B&W 7-Cylinder L70 ME-C8 engine demonstrated significant advantages of using Unitor™ FuelPower™ Soot Remover Liquid Plus. Benefits include extended exhaust gas boiler (EGB) cleaning intervals (12-15 months), prevention of acid formation and cold corrosion, and a reduction in soot fires and emissions. Additionally, the product minimizes the challenges of managing acidic wash water and is free of heavy metals like copper nitrate. The 24/7 support ensures consistent operational efficiency and environmental compliance.

Challenges with Soot Deposits

• Frequent cleaning every 2-3 months without proper treatment, resulting in resource strain, equipment wear, and higher operational costs.
• Environmentally challenging disposal of acidic soot-contaminated wash water.
• Efficiency loss due to soot buildup—just 1mm can reduce boiler efficiency by up to 10%—and an increased risk of fires and cold corrosion.

Industry Challenges

• Low-quality fuels with contaminants like vanadium, sodium, and metals hinder combustion.
• Exhaust gas boilers designed with low-velocity flue gas can lead to higher soot accumulation.
• Slow-steaming practices, common with modern engines, contribute to deposit formation and cold corrosion.
