The marine regulatory environment significantly impacts developments of the industry. This brings challenges but also opportunities. Having an innovative and reliable partner on board enables you to fully take advantage of those chances.
IMO 2020 Sulfur Cap
The International Maritime Organization (IMO) regulates shipping emissions globally, to reduce environmental pollution. Effective since Jan 2020, the allowed limit of sulfur in marine fuels was reduced from 3.5% to 0.5% globally, while in defined Emission Control Areas (ECA) the limit is 0.1%. This mandate is putting a severe challenge on refiners, who need to supply increasing volumes of compliant fuel blends, adapting to changing compositions. Bunker traders and ship operators must deal with price increases, a broad variety of fuel characteristics, stability and compatibility issues, and uncertain availability of the desired fuels.
At BASF's Fuel and Lubricant Solutions, we have a strong history in fuel additives. We leverage our experience to provide tailor-made additive formulations and help you overcome the various challenges that the sulfur cap is bringing (please scroll down further to Section 'Marine Fuel Additives'.
IMO NOx Regulation - TIER III
The control of greenhouse gases and pollutants, like NOx, is a major part of IMO regulatory activities. This becomes increasingly important, since control level Tier III reduces the limit of NOx emissions for larger ships significantly. IMO Tier III NOx controls have been applied in the North American ECA and US and Caribbean ECA since 2016 and will be introduced to North Sea ECA and Baltic Sea ECA in January 2021. Specified ships operating in these ECAs need to comply with Tier III limits. This usually affords the application of NOx control technologies.
Fuel in Water Technologies
Fuel in water technologies have been known to reduce NOx emissions in diesel engines for a long time. In the automotive sector the water represents only a minor share of the fuel mix. To comply with tier III limits in the marine industry, the amount of water needs to be significantly increased, up to 50% or more! The big ship engines can easily cope with this, if you use the right additives. At BASF we provide our customers with high-performance fuel additive packages to enable significantly reduced NOx emissions in a challenging fuel in water environment.
Besides the implementation of IMO 2020 S Cap, the agency is working to reduce GHG emissions from international shipping. The initial strategy envisages a reduction in total GHG emissions from international shipping and identifies these levels of ambition:
- Carbon intensity of the ship to decline through implementation of further phases of the energy efficiency design index (EEDI) for new ships to review with the aim to strengthen the energy efficiency design requirements for ships with the percentage improvement for each phase to be determined for each ship type, as appropriate;
- Carbon intensity of international shipping to decline to reduce CO2 emissions per transport work, as an average across international shipping, by at least 40% by 2030, pursuing efforts towards 70% by 2050, compared to 2008
- GHG emissions from international shipping to peak and decline as soon as possible and to reduce the total annual GHG emissions by at least 50% by 2050 compared to 2008 whilst pursuing efforts towards phasing them out as called for in the Vision as a point on a pathway of CO2 emissions reduction consistent with the Paris Agreement temperature goals.
Deeply anchored in its Corporate Strategy (Creating Chemistry for a Sustainable Future), BASF is fully committed to contribute to a sustainable development, and in consequence the reduction of GHG emissions.
Vessel General Permit (VGP)
The United States’ Vessel General Permit (VGP) program has brought very stringent regulations for the environmental friendliness of certain lubricants in the global shipping industry – such as those used for marine propulsion and steering systems. Environmentally Acceptable Lubricants (EALs) have become mandatory for lubricant applications where an oil-to-sea interface exists - such as stern tube, thrusters, propellers, stabilizers, and rudders. Beyond that, EALs are now also mandatory for wire rope and recommended for all other deck equipment (e.g., cranes, davits, winches, etc.).
The requirements for EAL‘s include:
- non or minimal toxicity
Lubricants labelled under OSPAR, Blue Angel, European Ecolabel and Swedish Standard are regarded as VGP-compliant. BASF offers great expertise in these relevant marine lubricant regulations and customers can benefit with our component solutions listed e.g. on LUSC, OSPAR etc. Furthermore, we can give guidance on regional chemical legislations like REACH, TSCA, K-REACH, etc.
Also see L. R. Rudnick; Lubricant Additives, 3rd Ed., Chapter 32, Eco Requirements for Lubricant Additives and Base Stocks (by Dr. M. Fies, Dr. T. Ruehle) for further details on EALs and bio lubricants in general.
At BASF's Fuel and Lubricant Solutions, we have a strong history in fuel additives. We leverage our experience to provide tailor-made additive formulations and help you overcome the challenges that the various regulations and changing environment are bringing.
Asphaltene Management Additives
Asphaltenes are polar macromolecules, which are usually kept in colloidal suspension in heavy fuel oils. Blending of these fractions with distillates, light cycle oils or marine gas oil may break up this suspension, leading to instable blends. These can be prone to aging and accelerated sedimentation or direct precipitation of the asphaltenes. Asphaltene management additives are specialized to mitigate the negative impacts on fuel stability caused by blending of incompatible fuels and fuel components. At BASF, we develop asphaltene stabilizers and tank cleaning dispersants. These prevent sedimentation caused by fuel aging (thermal or over time) and clean up deposits of asphaltenes.Furthermore, we offer compatibility agents which help to avoid asphaltene drop-out when blending of finished fuels occurs, e.g., in bunker tanks on-board or on-shore. As a result, less deposits form in tanks, pipes, filters and engines, and thus, safety and operating time will be increased.
Flow Improvers and Viscosity Modifiers
The broad variety of IMO compliant fuel oils also comes with significant differences in physical-chemical properties, such as viscosities and pour points. BASF offers a broad variety pour point depressants, flow improvers and viscosity modifiers, which help to bring these fuels in line and facilitate fuel handling.
Fuel in Water Packages
Fuel in water technologies have been known to reduce NOx emissions in diesel engines for a long time. In the automotive sector the water represents only a minor share of the fuel mix.
To comply with tier III limits in the marine industry, the amount of water needs to be significantly increased, up to a share of water that represents the majority of the mix!
The big ship engines can easily cope with this, if you have the right additives in place. We provide our customers with high performance fuel additive formulations to enable significantly reduced NOx emissions in a challenging fuel in water environment.

Durability and efficiency are key parameters when it comes to marine operations, especially around the engine. BASF offers several solutions to enable e.g. MCLs (Marine Cylinder Lubricants), TPEOs (Trunk Piston Engine Oils) and SO (System Oils) meeting increasing performance demands. Changing landscapes due to IMO 2020 S Cap, but also further emission & efficiency targets like NOx and GHG (Green House Gas) emission reductions (IMO 2030, IMO 2050) are of focus for us.
Durability: Over time and during operation deposits are formed inside of any maritime engine. These deposits are based on organic and inorganic products, as for example, Ca-sulfate and Ca-carbonates. Those Ca-deposites eventually shape into needle-like deposits that may limit engine efficiency, increase oil consumption and causes corrosion. BASF's Fuel and Lubricant Solutions offers optimized performance components which address these challenges and help to remove and prevent the build-up of both organic and inorganic deposits.
Efficiency: Just as more severe efficiency targets have been implemented in the automotive sector, regulations on efficiency and emission control have become increasingly important for the marine sector. Related to upcoming challenges on IMO 2030 & 2050 BASF has expertise and component solutions to solve these tasks of tomorrow and guide the marine industry into clear waters.
While addition of our IRGANOX® L antioxidants to a marine engine oil formulation provide protection against organic deposits and enables long-life operations, our specialized SYNATIVE® ES ester take it one step further. These esters can be used as cleanliness agents to address the issue of both organic and inorganic deposits. To achieve best results BASF recommends the combined usage of Irganox® additives and Synative® base stocks for optimized marine engine oil lubricants.

Heavy duty motors in marine applications have high demands due to their long operating hours and high load rates. Marine coolants must protect against both corrosion and cavitation. Cavitation protection is especially important due to the increased vibrations associated with heavy duty motors. BASF has a broad portfolio of premium engine coolants with and without frost protection and special fluids for engine preservation that offer long-life protection to prevent damages and reduce downtimes. In addition, BASF has produced GLYSANTIN® engine coolants for more than 90 years, demonstrating broad expertise. The premium quality of engine coolants is confirmed by the official approvals of engine manufacturers.
Marine engines are normally cooled by solutions of corrosion inhibitors and water that do not exhibit protection against freezing. However, for operations in winter or in cold waters like in the North Sea or in arctic regions, protection against freezing is also required. In such cases, we recommend that engines are cooled with a coolant that is based on glycols and water, as it is typical for Automotive engines. GLYSANTIN® premium engine coolant from BASF provides comprehensive threefold protection against corrosion, overheating and frost. GLYSANTIN® avoids deposits and gives a high degree of corrosion protection to engine components such as radiators, cylinder blocks/heads, water pumps and heat exchangers.
GLYSANTIN® products are officially approved by engine manufacturers. In the following only the relevant approvals for marine and industrial application are listed. Industrial engines are used for example as generator sets for power supply on ships and vessels.
