1500 Discussion and wrap-up



Blue Ocean Solutions has introduced Engine Performance Software to provide ship operators with a holistic insight into the operating condition and efficiency of the ship’s engine. The software is an important extension of the Emulsified Fuel System to verify the fuel savings gained from the system. It also evaluates the engine condition against factory test data and establishes current trending profile (patent pending) for preventive maintenance, restoring fuel efficiency and reducing emissions.

The software will be delivered as an add-on to Emulsified Fuel System at no additional cost. “We are dedicated to improve continuously and add value to our customers through innovation. We are also developing a fleet optimization suite to achieve profit maximization. It will use the latest technologies like cloud, artificial intelligence and chain-block with a seamless user friendly dashboard so that the user experiences the “intuitive power” but not the fear of “complicated to use”. This is one of the products and services that we are developing to help the maritime industry to meet the environmental challenges and to ensure a sustainable business.” says Jerry Ng Kok Loon, CEO, Blue Ocean Solutions.

The software together with BOS Emulsified Fuel System (EFS) can improve the profitability of ships significantly by reducing fuel costs by 2-5%, in particular, the impending 2020 0.5% Sulphur Cap when compliant fuels are expected to be more expensive. Currently, it is the only system with proven references that can operate with compliant fuel.

Analysis confirms that installing a BOS Emulsified Fuel System at the same time as a Selective Catalytic Reduction system delivers substantial cost savings

As BOS EFS can reduce NOx emission down to 20% at source (i.e during combustion), the size of SCR can be smaller. At the same time, SCR needs to produce less urea bringing down the operational cost as well.

For example,
CAPEX per SCR = USD3,000,000.00
CAPEX of SCR can be reduced by 20% i.e. USD600,000.00 savings

If the OPEX of the SCR is USD1,000,000.00
OPEX of SCR can be reduced by 20% i.e. USD200,000.00 savings



Installing EFS

The installation of BOS Emulsified Fuel System takes only 5 days in addition to another 5 days for commissioning the system. The installation does not disturb ship’s normal operation.

Emulsified Module

The system is modular and the only work needed on the ship is to do the connection work. Three by-pass valves would be installed to the fuel line by retro-fitting a small section of the FO pipe (between the circulation pumps and heaters).

When it comes to water-in-fuel emulsions, the concern over condition of the engine is often raised. Therefore, Blue Ocean Solutions engaged Flame Marine to conduct Cylinder Drain Oil analysis before and after the use of BOS Emulsified Fuel System. Flame Diagnostic provided a detailed diagnosis of wear, combustion, lubrication feed rate and performance. BOS Emulsified Fuel System has been running on 9 APL ships for over two years with regular monthly CDO-analysis. The results have showed that the engine condition improved after the use of our Emulsified Fuel System as the pictures below shows.

COD-ANALYSIS (0% and 8% water) – APL Barcelona


  • Engine Load & RPM                           : 21.7% / 57.8 RPM (MCR 54,120kW / 97 RPM)
  • Cylinder Oil consumption                 : 15.0 lit/hr (ExxonMobil Mobilgard 570)
  • Fuel Oil %S and Vanadium Content : 3.2% / 164 ppm (before engine)

BOS Emulsified Fuel System improves the combustion efficiency by producing stable water-in-fuel emulsions to improve injector fuel atomization. Other confirmed benefits are reduced NOx emission due to cooler combustion as well as cleaner exhaust and reduced PM emissions. Better combustion and presence of steam reduces and softens the soot. The system has been tested on Wärtsilä and MAN engines and on both two- and four-stroke engines. The performance of 2-5% fuel savings has been proven and verified by ship owners, Wärtsilä and classification societies DNV GL and Lloyd’s Register.


The International Maritime Organization’s (IMO) Marine Environment Protection Committee (MEPC) has agreed on mandatory requirements for ships to record and report their fuel consumption.

Shipping is the cleanest form of transport. However, there are 50,000 ships in the world and according to the United Nations Conference on Trade and Development (UNCTAD), around 80 per cent of global trade by volume and over 70 per cent of global trade by value are carried by sea and are handled by ports worldwide. At the same time the expected growth of world trade is putting more pressure on the future emission targets. Therefore, more measures and targets are needed to enhance the energy effiency of ships.

Last Friday, April 22nd, IMO’s Marine Environment Protection Committee approved a measure requiring ships over 5,000 gt to report fuel consumption (and therefore CO2 emissions) to their flag states.

Under the agreement, which will be drafted for inclusion under MARPOL annex VI at MEPC 70, ships of 5,000 GT+ will be required to collect consumption data for each type of fuel used in addition to other specified data.

This data will have to be reported to flag state at the end of each calendar year.

Under the ruling, if the ship’s consumption data meets requirements, the flag state will issue each ship with a statement of compliance and will transfer the anonymised data to the IMO Ship Fuel Consumption Database.

The data collection requirements could enter into force as early as 2018.

With consistent results, verified by independent classification societies on ships and engine manufacturer on test bed, Keppel Offshore & Marine’s subsidiary Blue Ocean Solutions (BOS) has proved that emulsified fuel can bring significant fuel savings adding to the well established NOx reduction, if done correctly.

The patented BOS Emulsified Fuel System (EFS) improves combustion efficiency by improving the injector fuel atomization. In addition to the measured fuel savings, firm evidence of better combustion has also been recorded in the form of increased  heat release rate.

The key success factor in emulsified fuel is the ability to produce and maintain the optimum 10% water as water-in-fuel particle sizes of 2-8 microns. This is achieved with the patented BOS Emulsifier that unlike other systems in the market, has no moving, cavitating or vibrating parts.

The system has been tested on both two-stroke and four-stroke engines. Diamond Shipping, one of the largest owner and operator of modern medium range product tankers in the world, was the most recent to place an order for BOS EFS to improve fuel efficiency. To date, references include American President Line (APL), Regent Seven Seas Cruises, Wärtsilä, Townsend Thorensen, London Overseas Freighters, B&I and others.

Despite the numerous references, Blue Ocean Solutions has been cautious with public announcements until there have been adequate independent verifications by namely: classification societies (DNV GL and Lloyd’s Register); engine manufacturer (Wärtsilä); and ship owners. It is important that the 2-5% fuel savings, trouble free operation and improved maintenance has to be independently verified. Anything else is hearsay and unproven.

Wärtsilä has also tested the system under the Project Hercules on medium speed engine Wärtsilä 6L20CR operating under Miller cycle with a two-stage turbocharger and running on MGO. The tests confirmed improved fuel efficiency with no need for chemical additives.

Even though Blue Ocean Solutions introduced the BOS EFS to the market in late 2010 in response to the sudden steep hike in fuel oil prices, the R&D work goes back to the early 1980′s. Dr Jerry Ng KL, the founder and CEO of Blue Ocean Solutions was one of the members of the team that pioneered the application of emulsified fuel technology to motor ships at the University of Newcastle, UK (Reference: Patricia A. Strandell & Henry W. Schab, “A REVIEW OF WATER EMULSIFIED FUEL INVESTIGATIONS FOR SHIPBOARD APPLICATIONS”, Naval Engineers Journal, March 1986.) He was awarded a scholarship in 1981 and the National Young Scientist & Engineer Award in 1989 for his work in emulsified fuel technology. At the 25th Sea Trade Award in 2013, Blue Ocean Solutions was commended for its contribution to clean shipping using BOS EFS.
