Oglebay Norton Company has announced the election of five corporate officers: Renold D.

Thompson, executive vice presi- dent of the company; Richard

J. Kessler, vice president-finance and treasurer; John L. Selis, vice president-administration and corporate planning; Robert A.

Thomas, assistant vice president- administration and general coun- sel; and David A. Kuhn, secre- tary.

Mr. Thompson, formerly exec- utive vice president-operations, joined the company in 1952 and has held several executive posi- tions. He is also a director of the company. Mr. Kessler, formerly assistant vice president-finance and treasurer, joined the compa- ny in 1969. He was elected treas- urer in 1974. Mr. Selis joined

Oglebay Norton in 1974. He was elected assistant vice president- corporate planning and tax coun- sel in 1980.

The final 1980-81 meeting of the Los Angeles Metropolitan Sec- tion of The Society of Naval Ar- chitects and Marine Engineers at- tracted 60 members and guests to the decks of the Princess Louise.

This session was dedicated to past chairmen of the Section and to the introduction of new officers, selected to serve for the 1981-82 season, which begins in Septem- ber. The new officers are: George

Stiehl, chairman of the Section;

George Henning, vice chairman;

Dr. Maxwell Cheung, secretary- treasurer; and Gary Cash and

Hans Schaefer, who were drafted to fill vacancies on the Executive

Committee.

Prior to the presentation of the evening's technical paper, chair- man-elect Stiehl presented a cer- tificate of appreciation to out- going chairman Edward (Ned)

Stewart for a job well done. He then introduced Robert Mende, secretary and executive director of SNAME, who was in town to discuss arrangements for the an- nual SNAME Star Symposium, to be hosted by the Los Angeles

Section in the spring of 1984 at

Century City.

The paper titled "OTEC-1

Mooring" was coauthored and presented by Harold Ramsden and William Watts of Global Ma- rine. Mr. Ramsden, who coinci- dentally was selected to hold the key position of Steering Commit- tee chairman for the Star Sym- posium, began by describing the

Department of Energy-sponsored

OTEC-1 program. That program was officially discontinued in

April 1981 after establishing three technological firsts: (1) the world's largest ammonia power plant; (2) the world's first sig- nificant large-scale cold water

In what may be maritime history, Bay-Houston Towing Company recently christened the four newest members of the fleet all on the same day. Left to right: The Captain W.D. Haden. the W.D. Haden, II. the Barbara H. Meuhaus and the Mark K. pipe; and (3) the world's deep- est large-capacity, single-point moor. The last "first" was the subject of the paper, and proved extremely interesting as a primer on a current stage of single-point mooring technology.

The mooring system was tai- lored to a site, off the west coast of the "big island" of Hawaii, chosen for the OTEC evaluation because it best met the 18 cri- teria established by the D.O.E.

The paper clearly detailed the material and technological trade- offs made by the Global Marine team, led by coauthor Watts, in progressing from a preliminary design to the exciting deployment of the operational mooring sys- tem that included a 300,000 pound chain "mass anchor." The pres- entation was followed by a lively question-and-answer session.

For those interested in gain- ing in-depth knowledge of the trials and tribulations required to design a successful single- point moor, a copy of the paper is available and may be obtained, for a reproduction and mailing fee, by writing to the SNAME

A FAMILY

AFFAIR.

The biggest harbor towing company on the "Texas Gulf Coast is no faceless corporation. It's

Bay-Houston Towing. And it's owned and oper- ated by the Hadens, a family that has been involved in the towing business for over 100 years.

That's why their fleet of diesel tugs, all the way up to the 4,200-horsepower Captain W. D.

Haden, bears family names.

Doing the job better than anyone else can is more than a challenge. It's a family tradition.
