It is anticipated that the plant will be able to recover sufficient vapor from a cargo lifted on the Stafjord field, for instance, to fuel a voyage to Rotterdam and back. More than 12 MC-series engines already on order have been pre- pared in mind of possible utilization of VOCs, which effectively means converting a pollution source into a clean energy resource. As a further key stage in the evolution of the two-stroke marque from Denmark, the concept of the 'intelligent engine' is set to be introduced into sea-going service this fall. Parallel to the refinements in engine and componentry design aimed at better ensuring minimal, unscheduled downtime, MAN B&W has devel- oped a family of software applica- tion products under the generic name computer-controlled surveil- lance (CoCoS). The move is in line with a shift from conventional pre- ventive maintenance practices to predictive maintenance using sophisticated, microprocessor-based MR/EN Marine Propulsion Supplement * September 1998 prop-17
