**Professors Daidola, Gallagher, Onas, Royce, and Werner**

The fundamental laws of buoyancy, stability, and strength are fully considered, as these have universal application to all kinds of ships and floating structures. The study of naval architecture is begun in the freshman year in order to familiarize the student as early as possible with ship and shipbuilding terms, technical facets of ship analysis and design, shipyard arrangements, and general methods of ship construction. Major subjects covered are hydrostatics, stability, ship structure, ship dynamics, resistance, and propulsion. Knowledge gained is subsequently applied in the design courses.

Owing to the wide variety of types and sizes of ships in service at the present time, it is inevitable that a certain amount of specialization is necessary for their design and construction. It is the aim of the courses to cover the fundamentals of naval architecture in the time available, so that the specialized study of any one of a number of particular types or classes of ships may be left to the individual who, after graduation, is especially concerned with them.

**ENGINEERING ECONOMICS**

Coverage of the principles of engineering economics, including compound interest, present worth, annual cash flow, rate of return, depreciation, taxes, and replacement analysis. One hour per week in the first semester senior year.

**THESIS**

In order to qualify for graduation, each student in the senior year is required to prepare and submit a written thesis, in or related to the field of naval architecture or marine engineering under the direction of a member of the faculty. Senior theses may be individual or team efforts. In addition to a written thesis, seniors are required to present orally the results of their thesis efforts to the assembled student body, faculty, and administration in the late spring of their senior year.

**SENIOR SEMINAR**

The Senior Seminar, conducted during the final semester, is designed to introduce the seniors to the human factors, business considerations, management techniques, and analytical concepts they may expect to encounter after graduation. Seminar leaders are drawn from the Webb staff and from business and industry. Subjects range from labor-management relations to systems engineering. Content will vary from year to year dependent both on student interests and on developments in the area covered.

**SPECIAL TOPICS**

These three-credit courses represent the two opportunities for electives at Webb. The first is a humanities or social science course chosen by the students from a list of suggestions provided by the Dean and augmented by the students themselves. If sufficient interest in a topic exists, distinguished members of academia and/or industry are sought to teach the courses. These courses are intended to broaden the students’ view of the world and are offered during the fall semester of the junior year, three class hours per week.

The second course is a technical elective again chosen by the students from a list provided by the Dean and augmented with their suggestions. This course provides an opportunity for Webb to engage distinguished visiting faculty to share their particular expertise and real world experience with interested students (and faculty).

These courses provide a way to either sharpen the focus of a student’s program or to expand the scope of his/her undergraduate experience. This course is offered three class hours per week in the final semester of the Webb academic program.

**PRACTICAL WORK (aka WINTER WORK)**

Webb will assist in securing positions with advice to the students and the establishment of liaison with various companies. The sequence usually consists of working as a helper mechanic in a shipyard the first year; as a cadet/observer in the engine room of a ship the second year; and in a professional capacity as an engineer in the industry the third and fourth years. The students are paid at the going rate of their jobs, sufficient to support themselves while away from school. Housing can usually be located through the company employment departments.

Each student is required to present a technical report on the practical work undertaken during each of the four winter intersessional periods. The immediate supervisor is also invited to comment on the student’s performance. Additionally, a Sophomore Sea Term Project is required following the work term spent aboard ship.

**ENGINEERING VISITS**

Visits of inspection are made by individual classes to nearby shipbuilding, dry docking and repair yards, other engineering plants, and to vessels in the vicinity. These visits are arranged through the courtesy of the managing officials of the companies.

In order to develop their powers of observation and to improve their ability to write technical reports, the students are required to submit brief reports of their observations immediately after each visit.

**PROFESSIONAL SOCIETY MEETINGS**

During the spring semester, the entire Junior class attends the Offshore Technology Conference (OTC) in Houston, Texas. The entire Senior class attends the Society of Naval Architects and Marine Engineers (SNAME) conference during the fall semester. Students regularly attend local professional society section meetings throughout the year.
