EMMIF: Getting Heavy With Bunkers

Higher viscosity bunker fuels do not automatically contain more harmful elements than lighter ones, according to ExxonMobil Marine Fuels (EMMF), which has recently been supplying 500 centiStokes fuel in response to customer demand.

Emphasizing that quality and safety must be prime considerations with all fuel supplied, irrespective of viscosity, EMMF says the two crucial prerequisites for using 500 cSt fuel are the ability to heat it to a sufficiently high temperature to inject it into the ves- sels' engines, and the provision of purification equipment able to deal with the higher specific grav- ity of the product.

The fuel must be maintained above its minimum pumping viscosity while in storage awaiting use.

Storage tank heating coils are required, which are able to maintain the fuel at a stored temperature at or above 45 degrees C. Modern purifier systems are capable of ensuring that the fuel is effectively and sufficiently cleaned. Finally, the ship's main engine fuel oil pre-heaters must be able to raise the fuel to between 140 and 155 degrees centigrade. At these temperatures the new fuel is at the typical engine fuel injection viscosity of between 15 and lOcSt.

The additional heating required to use the 500cSt fuel should be easily covered at sea by the vessel's exhaust gas boiler. In port, the boiler will typically consume extra fuel to maintain oil storage tank tem- peratures. But EMMF points out that, given the sav- ing in the initial cost of the 500cSt product and the limited in-port time of many vessels today, there is the potential for significant savings to be made.

Many shipowners are now able to benefit from the possible cost savings involved in using heavier fuel without impairing the performance of their vessels.

EMMF says that shipowners whose vessels can use the fuel may realize considerable economies over the course of a vessel's annual operational life.

Onboard-Napa Power

Yields Fuel Savings

Onboard-NAPA Power is a state-of- the-art optimization tool for ship opera- tion, developed by Onboard-Napa Ltd.

The latest version of Onboard-NAPA

Power features automatic ship-to-shore reporting of fuel consumption and fuel inventory with Web-browser-based viewing.

The complete 3-D hydrodynamic model of the ship is used together with the latest weather arid sea-state forecasts and current data in defining the optimum operation profile. The ship's current trim and draft are also taken into account.

All main and auxiliary engine config-

U.S. Navy & Industry urations can be handled, including the latest gas j turbine installations and electric podded propul- sion systems. Interfaces to navigation, weather and machinery automation IT systems are included, b-— thereby minimizing offi- cer input. All data related to planning and actual performance during the voy- age or cruise can be saved and reported.

The fuel consumption and inventory data reported ship-to-shore can be stored on a company intranet server for easy distribution.

For example, the financial and techni- cal departments can utilize this data by means of a simple Web-browser-based interface. Office personnel on shore and crew mem- bers are able to follow the fuel consumption of each fleet vessel during differ- ent voyages.

Onboard operational optimization and accurate ship-to-shore reporting are effective incentives for economical ves- sel operations. The existing installations have on average resulted in fuel savings of at least three percent.

Lubricating System

Mitsui Engineering & Shipbuilding

Co. (MES) has developed a new elec- tronically-controlled lubricating system, which will reduce the consumption of diesel engine cylinder lubricating oil.

Known as the Alpha Lubricating

System, the device recently achieved a high level of savings in cylinder oil on a large containership of 4,900 TEUs, which is equipped with a Mitsui MAN

B&W 10K90MC engine of 59,00 bhp.

At last count, the saving rate of the ship as of today is 20 percent plus, and it is expected to reach more than 50 percent in the near future.

The Alpha Lubricating System, by application of the electronic control device, can quickly inject the oil at opti- mum timing, and can easily be installed on existing engines.

Vickers1 Hydrox Bio 68

Garners Recognition

Sterntube oil manufacturer Benjn. R.

Vickers & Sons was honored for its unique, new lubricant — Hydrox Bio 68 — at this year's Sea Trade Awards. The award, which was presented in the

Protection of the Marine and

Atmospheric Environment category, was presented to Peter Vickers, the compa- ny' chairman and managing director. In 2002, after more than five years of research and development trials, the

U.K-based company introduced Hydrox

Bio 68 — a readily biodegradable stern- tube lubricant. The product, which embodies all the essential features of the

Hydrox range, is also designed to have minimal impact on the marine environ- ment. In fact, external tests on the prod- uct have demonstrated its low toxicity and its non-toxic effects on fish, daphnia and shrimp.
