Professors Wiggins, Gallagher, and Werner

This division includes those courses that pertain directly to marine machinery. The sequence begins with an introductory survey of propulsion requirements and alternative systems. In the following years, detailed studies of machinery and systems are undertaken, including design aspects of steam generators, steam and gas turbines, diesel engines, power transmission systems, pumps, blowers and heat exchangers. The concepts of system integration, configuration management and rational evaluation of alternative approaches are stressed. The sequence culminates in a project in which the students prepare an outline proposal for a complete power plant for a specific application and undertake an investigation of its economic merit in comparison with a group of likely alternatives.

INTRODUCTION TO MARINE ENGINEERING SYSTEMS (ME I)
A case study is used to present the issues involved in selection of a propulsion system for a ship. Following the case study, the details of steam and diesel propulsion are presented. Construction and operation of important components are discussed. The course includes field trips to visit ships and other marine facilities. Two hours per week in the second semester.

MARINE ENGINEERING SYSTEMS COMPONENTS (ME II)
This is a continuation of Marine Engineering I. Gas turbine propulsion and combined cycle propulsion are discussed. Auxiliary equipment are covered, including: air compressors, heat exchangers, oil purifiers, steering machinery, distilling plants, refrigeration, and electrical systems. The course includes field trips to visit ships and other marine facilities. Two hours of class and two hours of laboratory per week in the first semester.

MARINE ENGINEERING MACHINE DESIGN (ME III)
This course involves the design of specific machine elements such as shafts, gears, couplings, clutches, brakes, screw fasteners, and joints. It applies the theory from the Strength of Materials course to practical problems in machine design. In addition, dynamic and fatigue analysis are introduced. Marine examples are used for the various elements, such as marine gearing and shafting. Three hours per week in the second semester.

APPLIED MARINE THERMODYNAMICS (ME IV)
The course consists of three distinct, related parts. Part one deals with the thermodynamic design of a combined steam turbine/gas turbine system. Design trade-offs and optimization are included. Part two deals with the design of the steam turbine from part one. Both thermodynamics and fluid mechanics considerations are included. Part three provides coverage of heat transfer. One dimensional steady and unsteady conduction and the empirical approach to convection are included. Brief coverage of radiation is provided. This part of the course culminates with the design of an intercooler for the gas turbine system from part one. Design trade-offs and optimization are included. Three hours per week in the first semester.

SHIP AUXILIARY SYSTEMS DESIGN (ME V)
This course covers the design of shipboard machinery systems, building on the introduction of Marine Engineering II and the students’ examination of systems while on board ships. The principles of fluid flow are used to design pumps, piping and hydraulic systems. Heating, ventilation, and air conditioning design is covered. The final part of the course introduces monitoring and control systems, using analog/digital conversions, programmable logic controllers and feedback controls. Throughout all of the design work, consideration of the relevant regulatory requirements is included. Three hours of class and two hours of laboratory per week during the second semester.

SHIP PROPULSION SYSTEMS (ME VI)
This course includes a detailed analysis of diesel engines, a review of gas turbines, and completion of a machinery plant design for the vessels used in the naval architecture sequence. This design exercise draws on all the prior marine engineering courses as well as the student’s shipboard experience, in that all the propulsion and auxiliary equipment items are selected and the related machinery systems are designed to support them. A lab sequence involving hands-on work with low-speed and high-speed diesels is included. Four hours of class and two hours of laboratory per week in the first semester.
