Restricted Draft Carriers

Compared To Conventional In

Report By Hydronautics

A report, "Concept Design and Cost Analy- sis of Restricted Draft Dry Bulk Carriers," submitted to the U.S. Army Engineer Institute for Water Resources by Hydronautics, Inc., 7210 Pindell School Road, Laurel, Md. 20810, is being -distributed to a limited number of agencies and private parties and firms to whom the subject matter is considered to be of in- terest from a professional, program, or busi- ness point of view.

The report develops and describes design characteristics of restricted draft dry bulk earners and compares the operating and capi- tal costs of such carriers with carriers of con- ventional design.

The restricted draft concept is relevant to oceangoing carriers whose conventional design draft would exceed the permissible draft in ports and channels which they would serve.

This condition exists at a number of U.S.

East and Gulf Coast ports and channels through which dry bulk import and export commodities move, such as grains, coal, phos- phate rock, and iron ore.

SNAME Los Angeles Discusses

Undersea Pipeline Technology —Past Chairmen Honored

Springett, author; Dr. Yoram Goren, author, and Frank

Nickels, chairman of the Section.

Eighty-one members and guests assembled aboard the S/S Princess Louise for the last meeting of the 1973-74 season of the Los An- geles Metropolitan Section of The Society of

Naval Architects and Marine Engineers.

The feature of the evening was the presen- tation of a paper on "The Application of Mod- el Testing to the Design of Stingers for Pipe- laying Barges," by Charles N. Springett and

Dr. Yoram Goren of Santa Fe Engineering

Services. The meeting was also highlighted by a visit from Phillip Eisenberg, the presi- dent of the Society of Naval Architects and

Marine Engineers, and by the presence of several past chairmen on hand for the annual

Past Chairmen's 'Night activities, and by the election of officers for the 1974-75 season.

Mr. Eisenberg spoke to the members about recent Society activities on the national level.

He discussed the recent reorganization of the

Society's Technical and Research Committee and the recently inaugurated program of na- tional meetings on Ship Technology and Re- search (STAR).

The subject of the paper was particularly timely in that economic forces are currently taking offshore drilling activity to unprece- dented depths and distances from shore. This has led to quantam jumps in undersea pipeline technology, not the least of which is the de- velopment of high-capacity stingers for pipe- laying barges. The paper describes how model testing was used to assist in the design of two advanced pipela'ying barges—the Choc- taw I and Choctaw II. An excellent film was shown of the Choctaw I during design, under construction, and in operation in Bass Strait.

Past chairmen of the Los Angeles Metro- politan Section in attendance included Phil

Finkelstein (1954-55), Lou Dingier (1962-63),

Nat Friedland (1967-68), Henry Rumble (1968- 69) Bob Rourke (1970-71), and Tom Wilson (1971-72).

The officers elected for 1974-75 were Charles

Pollock, chairman; Harry Levy, vice chair- man; Bob Apple, secretary-treasurer, and John

Graham to the executive committee.
