Steam Propulsion Control System Study. Phase I:Throttle Control System Reliability Improvements. Volume I:Executive Summary and Final Report.

摘要

The Steam Propulsion Control System Study Phase I Final Report presents recommended modification alternative for improving the operational reliability of existing throttle control systems. The report examines throttle control system configurations for an electro-hydraulic system and an electro-pneumatic system as installed aboard U.S. Flag merchant vessels and an electro-hydraulic system of foreign manufacture which is considered to have high operational reliability. The development of the modification alternatives is described through a discussion of the failure history of existing throttle control systems and the priorities placed on these failures. The report concludes that some improvement in the operational reliability of throttle control systems could be realized by the implementation of some or all of the modifications on any particular vessel. Estimated cost of each modification is identified to enable each operator to make an evaluation of the cost effectiveness of these modifications in fleet operations. A program for further development of advanced centralized steam propulsion systems is proposed.
