Selection of the Power Plant for an Alaskan RO/RO Ship
In 1996 TOTE began a Maritech project with NASSCO aimed at looking at replacement tonnage for their existing fleet of steamships. The Maritech study started with a single-screw, slow-speed diesel ship that in essence would have been a lengthened Pfeiffer containership. Between the capacity and speed requirements of the trade, it became evident that a twin-screw ship was required with greater beam than the Pfeiffer. It was also clear that the short run of the ships heightened the relationship between port time and sea speed, and that from a cargo load and discharge time, certain machinery arrangements were more favorable than others. The original 17 power plant options were reduced to four options that were studied in detail. This paper endeavors to document the decision process and the economic and operational comparisons that were made.
