93rd SNAME

Annual Meeting — A Preview and chief operating officer of Beth- lehem Steel Corporation.

The David W. Taylor Medal "for notable achievement in naval archi- tecture" will be presented to J.

Randolph Paulling Jr., professor of naval architecture at the Univer- sity of California in Berkeley.

Thomas B. Crowley, president of

Crowley Maritime Corporation of

San Francisco, will receive the Vice

Admiral "Jerry" Land Medal "for outstanding accomplishment in the marine field."

The Blakely Smith Medal "for outstanding accomplishment in ocean engineering" will go to John

A. Mercier, senior staff naval ar- chitect, Continental Oil Company,

Houston. The Elmer A. Sperry

Award for 1985 will be given to

Richard K. Quinn, Carleton E.

Tripp, and George H. Plude for design concepts and construction methods of the Stewart J. Cort, the first 1,000-foot self-unloading Great

Lakes bulk carrier.

The 93rd Annual Meeting will come to a gala conclusion on Satur- day evening with the dinner-dance and entertainment in the Grand

Ballroom, with more than 500 cou- ples expected to attend.

Technical Papers (See table for time and location.)

Paper No. 1—"Evaluation of the Longitudinal Ultimate Strength of Various Ship Hull Configura- tions," by Lembit M. Kutt,

Christopher M. Piaszczyk,

Yun-Kuand Chen, and Donald

Liu.

SYNOPSIS—The longitudinal ultimate strength of several ship hull configurations is analyzed with the nonlinear finite element meth- od. Included in each analysis are the effects of buckling, post-buckling, and plasticity, and their proper in- teraction. In addition, an extensive treatment of the modeling proce- dures for nonlinear finite element analysis and a study on the sensitiv- ity of the ultimate strength to varia- tions in several parameters are in- cluded.

Paper No. 2—"Strength Evalu- ation of a Novel Unidirectional

Girder System Product Oil Carrier by Reliability Analysis," by Tom- iyasu Okamoto, Tohru Hori,

Masuru Tateishi, Sherif M.H.

Rashed, and Shigeru Miwa.

SYNOPSIS—This paper de- scribes the design concept of a new- ly developed product oil carrier, of which double hulls are stiffened only by longitudinally arranged girders. The structural safety in ex- treme loads and the redundant strength in damaged conditions are discussed, applying reliability anal- yses. Based on these results, the <• Circle 202 on Reader Service Card structural system is found to offer more safety than conventional de- sign.

Paper No. 3—"Prediction of the

Behavior and Propulsive Perform- ance of Ships with Bulbous Bows in

Waves," by Peter Blume and

Alfred M. Kracht.

SYNOPSIS—As a result of re- search programs performed by the

Hamburg and Berlin, West Germa- ny, Model Basins, design data are now available for the estimation of the seakeeping qualities of bulbous bow ships. Studies on speed loss under service conditions yielded that bulbous bow ships have almost the same seakeeping qualities as comparable ships without bulbous bows in sea states up to Beaufort 6.

Thus the bulbous bow may be de- signed with regard to its smooth- water performance only. It is pru- dent, however, to avoid extremely large bulb bodies.

Paper No. 4—"A Realistic Ap- proach to Semisubmersible Stabili- ty," by Dracos Vassalos,

George Konst antopoulos,

Chengi Kuo, and Yousri We- laya.

FRESHWATER AND SALTWATER CAPABILITIES ...IN A COMPETITIVE, QUALITY SHIPYARD! • SALTWATER SHIPS and TUG/BARGES to 760'. • GREAT LAKES SHIPS to 1,100'. • LARGE GRAVING DOCK...1,158' long with a travel- ing gantry crane capable of handling up to 200-ton super-sections, fabricated simultaneously at numer- ous adjacent locations. • COMPLETE IN-HOUSE CAPABILITIES... to design, engineer, build, repair, convert, re-power, retrofit and jumboize. • BUILDING SHIPS SINCE 1902 ... an established company with modern facilities, including computer lofting and burning.

Bay Shipbuilding Corp. has built more modern self- unloading vessels than any other shipyard in the

United States. In addition, many other vessels have been converted to self-unloaders.

Our Company's 80-plus years of expertise is the pri- mary reason we routinely deliver on schedule.

Our personnel have experience in coal and oil-fired steam propulsion and diesel ships. Our experience also includes the construction of commercial ocean tankers/barges and chemical carriers, dump barges, derrick ships, passenger ships, tug/barge units includ- ing self-unloading barges, stern trawlers, and indus- trial products.

WE'RE READY TO SERVE YOU...
