New York SNAME Hears Paper On

Computer-Based Preliminary Design

A recent meeting of the New

York Metropolitan Section of The

Society of Naval Architects heard a paper titled "A New Approach

To Computer-Based Preliminary

Ship Design." The authors were

Dr. Farrokh Mistree and Timo- thy D. Lyon, both of the Univer- sity of Houston. The following par- agraph is a brief abstract of their discussion.

This paper presented a new computer-based method to carry out the preliminary design of ships using the latest advances in com- puter programming and optimiza- tion approaches. It uses an ad- vanced, multiple objective, non- linear optimization package that can handle the most complete de- sign problems. The program has consistently produced designs that

Call For Papers Issued

For 7th Chesapeake

Sailing Yacht Symposium

Organizers of the Seventh Ches- apeake Sailing Yacht Symposium have issued a call for papers for the one-day gathering, scheduled for January 19, 1985 in Annapolis,

Md.

The symposium, which tradi- tionally attracts more than 500 people, including some of the na- tion's top yachting figures, is solic- iting papers on a variety of topics, including 12-meter developments, yacht design, performance, mate- rials and construction, cruising, racing, historical subjects and sails and rigging. are superior to those using con- ventional methods. The new method makes an important con- tribution toward the automation of the preliminary design stages.

Nicholas Bachko was the ho- nored guest at the meeting. Mr.

Bachko graduated from the U.S.

Merchant Marine Academy in 1942, and sailed as a merchant marine officer until 1946. He came ashore with United States Lines, rose through the ranks from assis- tant superintendent engineer to senior vice president for planning and development, and retired in 1979. He joined SNAME in 1950.

He is a Life Member of the Society and serves as a member of the

Technical and Research Steering

Committee.

The deadline for 400- to 500- word abstracts of proposed papers is May 1, 1984. Authors of selected proposals will be advised of accept- ance by June 1 and will be ex- pected to submit drafts of their pa- pers by August 1. Final papers are due October 1, 1984, to allow time for printing in the book which each symposium-goer receives.

Abstracts and inquiries should be sent to Otto Scherer, chair- man of the Papers Committee,

Chesapeake Sailing Yacht Sympo- sium, 5475 Greenbridge Road,

Dayton, Md., 21036.

Baldt Introduces New

Workboat Connecting Link —Literature Available

Baldt Inc., following two years of development, has just intro- duced an advanced, anti-corrosive connecting link. Rocco Albertini,

Baldt's director of engineering, de- scribes the new link: "Three exclu- sive features provide dramatically increased resistance to corrosion.

One, a totally new steel alloy that is less sensitive to corrosion; two, a unique new protective coating; and three, an added forging pro- cess called restrike that insures fit and increases fatigue life. This new Baldt Workboat Connecting

Link is less susceptible to corro- sion, so throughout the normal op- erating process the new link will reduce routine maintenance."

Mr. Albertini continued, "Not only is the alloy less corrosive, but it affords extended fatigue life.

The alloy has high tensile impact properties, and Grade 3 load re- quirements as established by the

American Bureau of Shipping."

Baldt modeled the Workboat

Connecting Link after its own re- liable U.S. Navy design. Like the

Navy link, each section is individ- ually fitted. Sections are not inter- changeable, so in a real sense every link is custom made. Baldt is the largest supplier of anchors, chain, and hardware to the U.S.

Navy.

The patented metallic ceramic coating Baldt as applied to the link gave the best results among six coatings evaluated and tested over a two-year period. Because

Baldt feels the coating is far supe- rior to other materials, the com- pany will also offer custom coating for hardware items such as swivels and pear-shaped links.

Testing is equally rigorous dur- ing manufacture, and it exceeds

ABS specifications. Every link is subjected to 100-percent magnetic particle testing, and all mechani- cal properties are evaluated.

Made exclusively in the U.S.,

Baldt Workboat Connecting Links are available in sizes ranging from 3/4-inch to 1-3/4 inches, and are quickly identified by Baldt's unique grey coating and red, white and blue label.

Baldt, Inc. designs, engineers, manufactures, and internationally markets a complete line of anchor- ing and mooring systems for the marine and offshore industries, and drag chain systems for the mining industry. With offices throughout the U.S. and the U.K., the firm provides extensive custom design and engineering services.
