Oosterhuis Talk Describes Decline In Fuel Quality- Free Copies Available Herman H. Oosterhuis, presi- dent of Oosterhuis Industries, Inc., believes that the quality of fuel keeps going down, the de- cline in quality being widespread in some areas and worse in oth- ers. In a talk at a technical ses- sion of the Workboat Show held in New Orleans, Mr. Oosterhuis said that the United States has long been blessed with clean, low- sulphur diesel fuel. "Apparently, this era is now coming to an end, and is causing problems for many high-speed engine users. Most lower-horse- power, high-rpm diesel engines that are designed for operating on gas oil and ASTM No. 2 diesel are seriously affected," he pointed out. In an excerpt from his well- received talk, he pointed out that American manufacturers have done wonders, particularly dur- ing the past decade, with improv- ing on fuel efficiency of steam plants. "It nevertheless appears that the U.S. merchant marine is now heading for at least par- tially switching over to diesel en- Herman H. Oosterhuis gines capable of burning heavy fuel, and the industry is catching up rather rapidly. "They have been historically steam-oriented, contrary to over- seas, where the diesel has been king for more than half a cen- tury. U.S. engine manufacturers of higher-horsepower, medium- speed engines already have expe- rience with heavy fuel, and as- sembly in the U.S. of big-bore diesels has recently become a fact," he said. Mr. Oosterhuis pointed out that the interest shown by the U.S. Maritime Administration for heavy-fuel engines, and the fact that more and more engineers will become thoroughly familiar with the operation of heavy-fuel diesels will, no matter how re- mote it may sound, in the long run be beneficial to the workboat industry. Mr. Oosterhuis, who is a native of Holland, is a graduate of the Amsterdam Marine Engineers College.
