Philadelphia Sections, SNAME

And IEEE Hold Joint Meeting

The Annual Joint Meeting of the Philadel- phia Section of The Society of Naval Archi- tects and Marine Engineers and the Philadel- phia Section of The Institute of Electrical and

Electronics Engineers, Inc. was held on March 16, 1973, at the Philadelphia Engineer's Club.

George C. Janzen of the Naval Ship Engi- neering Center, Philadelphia, presented his pa- per entitled "Electrical Systems on High Per- formance Vessels." His paper discussed the fol- lowing areas:

The United States Navy is presently initiat- ing some challenging programs for ship con- struction in the areas of combatant, hydrofoils, air cushion and surface effect ships. These de- signs place considerable burden on subsystem designers to achieve minimum weight and space-consuming features within ever-present economic constraints. This paper is a general discussion on the use of 400 Hertz electrical systems as a means to satisfy some of these de- sign objectives. A brief description is given of previous studies, hardware developments and present status of 400 Hertz electrical power systems. Problem areas, including costs, reli- ability, and maintenance philosophy, are dis- cussed. Some thoughts are presented on the need for future studies and hardware develop- ment to identify meaningful trade-offs. One of the most important trade-offs discussed is in- creased equipment cost versus the value of weight and space saving for various ship types.

Some projections are offered on high-perfor- mance ship electrical system trends over the next 10 to 15 years.

W. Hemphill of the Philadelphia Naval Ship- yard acted as coordinator for the joint meeting.

Energy And Environmental

Needs Can Be Met In Florida

Says Exxon USA's E.A. Humble

There is a continuing need for Government, industry, and the public to work together to as- sure that energy supplies can be moved eco- nomically where needed in the state of Florida, while at the same time working just as hard to protect the environment, E.A. Humble,, manager of Exxon USA's Marine Department, said in

Tallahassee when speaking at the Governor's Con- ference on Energy Supply and Use.

Mr. Humble said: "This means that environ- mental laws and regulations must strike a proper balance between state and national energy de- velopment and supply on the one hand, and pro- tection of the environment on the other. "If we work together to achieve this objective, both the consumer and the national interest will benefit," he stated.

Mr. Humble explained that more than 76 per- cent of Florida's fuel requirements arrived by water in 1971, and that the 200-million barrels of oil which entered the state flowed through 10 ports. "Supplying this portion of Florida's energy needs required 1,100 deliveries in tankers with an average cargo capacity of less than 25,000 tons," he pointed out. "These ships are rather small when compared to those being constructed with capacities of 250,000 or 500,000 tons. Use of smaller tankers here is the result of two factors— the dispersion of traffic among many ports and the shallow depths found in tbese ports. These limiting factors require Florida's oil trade to be carried on by a rather large number of relatively small vessels. "It appears that by 1980, Florida will require 322-million barrels per year of petroleum prod- ucts," he stated. "If deliveries continue to be made by vessels of the same size and carrying capacity as are used today, we can predict that between 1,700 and 1,800 tankers will call in

Florida's ports in 1980, compared with the 1,100 in 1971. "In the simplest terms, Florida's growing en- ergy demand will require substantial increase in the use of tankers and bulk cargo terminals. This, in turn, will increase the potental for pollution."

Three factors come into play in minimizing the effects of oil spills, he explained. "First, there is the matter of operator technology, equipment, and dedication. Second, there are governmental regulations designed to minimize oil spills. Third, measures can be taken to reduce the expected growth in tanker calls on Florida ports."

In discussing the future of ports in the U.S.,

Mr. Humble urged that consideration must be given to offshore terminals or "superports." "However, because Florida's oil receiving loca- tions are so widely dispersed around the coast, an offshore terminal could probably not be justi- fied here," he stated. "For the foreseeable future, offshore terminals will he feasible only in refining centers—such as Texas, Louisiana, and along the upper East Coast."
