Drew And MAN B&W Conduct Joint Tests On Fuel Additive

Drew Ameroid Marine recently announced that it has completed a series of tests jointly sponsored with MAN B&W Diesel using Amergize® deposit modifier/combustion improver.

The extensive tests, conducted on diesel engines both on a turbocharger test bed and on-board a ship, demonstrated the positive effect that the Amergize fuel additive has in reducing and preventing deposits on turbochargers of engines that burn today's heavy fuels.

The test rig at the Augsburg, West Germany, facility of MAN B&W was used to simulate fouling situations that these highly reliable and efficient turbochargers may experience.

In these tests, Amergizetreated fuel at varying concentrations were compared with a baseline test. These tests showed not only that Amergize can reduce the fouling of a turbocharger, but that it can be done at economical dosages.

After completion of the test-bed evaluations, MAN B&W and Drew agreed to jointly sponsor shipboard trials. The vessel chosen had a medium- speed diesel engine with temporarily poor turbocharger efficiency.

The ship's crew had to waterwash the T/C every 100 hours, and the T/C required frequent mechanical cleanings. This ship was chosen to see if Amergize, when applied at economical dosage rates, would significantly reduce the frequency and severity of the fouling.

After six months of comparing the baselines to the results achieved with Amergize, it was found that the ship could operate for three or more months without cleaning the turbocharger.

In fact, this period might be extended, but this was the longest period during the trial in which the ship ran on Amergize. The results show that by using Amergizetreated fuels, diesel engines are able to burn blended fuels resulting in less harmful fouling, lower fuel consumption, and reduced maintenance.

Amergize fuel additive is the latest in new technology from Drew Ameroid. It is used on more than 800 ships worldwide, and has also been tested by independent laboratories with impressive results.

Drew service representatives will assist ship managers in determining specific treatment rates and dosing procedures for Amergize. In addition, the company offers its Pace® fuel evaluation program and its Red Carpet Service Program for any ship starting on Amergize, to identify the characteristics of the fuel aboard and determine dosage levels.
