Propulsion: Optimizing Feed Rates For Crosshead Diesels
ExxonMobil introduced a program to optimize cylinder oil feed rates in low-speed (crosshead) diesel engines. The "Feed Rate Optimization" program is designed to help minimize operating expenses by analyzing scrapedown oil as a way to detect changes in the condition of an engine¹s cylinders. The program, which is designed to help customers find a balance between the cost of cylinder oil and the expense of wear-related cylinder maintenance, analyzes scrapedown oil collected from the engine’s scavenge space, a technique pioneered by ExxonMobil. It is designed to provide comprehensive laboratory testing and analysis of the oil sample, and offers onboard testing tools that enable ship’s engineers to quickly detect substantive changes in cylinder condition.

New Technology Debuts in Oslo
NorShipping 2001, held in Oslo, Norway in early June, once again proved to be a dynamic exhibition complete with some of the more influential personnel in the marine business on-hand for the week long event. As usual, marine manufacturers used the platform of NorShipping to launch new products, systems and services to the international market, some of which is detailed in the following report. Wärtsilä Corp., the ubiquitous propulsion system manufacturer announced that it had received a contact to supply the complete marine power system for the first of a series of environmentally safe 40,000-dwt chemical/product tankers building at the San Marco shipyard in Italy. For the 40,000-dwt tankers, Wärtsilä will be just that, as it is responsible for the complete functionality of the system.
