Meeting held recently at DTNSRDC.

The David Taylor Naval Ship

R&D Center (DTNSRDC), Car- derock, Md„ hosted the 1981 Na- val Sea Systems Command Hy- dromechanics Committee (SEA-

HAC) recently. The two-day meeting was attended by nearly 200 persons representing the pri- vate sector, academic institutions, and Navy activities. The meeting is held annually and provides a forum for the transfer of tech- nology.

SEAHAC, established in 1950, acts as an advisory body for re- search and development in the field of naval hydromechanics.

This committee is comprised of representatives from the Naval

Sea Systems Command together with representatives from Navy laboratories, National Bureau of

Standards, the Office of Naval

Research, and the Naval Acad- emy. SEAHAC is responsible for making specific recommendations regarding the technical objec- tives, forecast of research needs, development of priorities, order of procedures, methods and means of investigations, and related items of importance.

Technical subcommittees of

SEAHAC are organized to repre- sent the following principal tech- nology areas in the field of naval hydromechanics: resistance and propulsion, seakeeping, maneu- vering and control, propulsors, hydro-acoustics, fluid /structure interaction, and weapon launch.

In addition to these areas, topics of the meeting included overviews of current Navy research pro- grams and current exploratory development programs.

Rear Adm. James W. Lisanby,

USN, Deputy Commander for

Ship Design and Integration, Na- val Sea Systems Command, was guest speaker at the luncheon held on May 19. He reviewed briefly recent progress on ship

R&D by reflecting on remarks he had made at the 18th Towing

Tank Conference in August 1977.

To this end he recalled the fol- lowing suggestions he had made then and identified recent accom- plishments for each: (1) "Better coordination, co- operation, and communication among Navy policymakers, re- searchers, designers, and ship forces in establishing R&D pri- orities. (2) "More pooling of resources within the engineering commu- nity. (3) "A closer working relation- ship among the ship acquisition and R&D managers, and especi- ally, ship designers and re- searchers. (4) "Sharpen the long-range vi- sion of the ship designer so that he or she could look ahead and predict 15 years hence what our ships will require. (5) "We need a continuing ed- ucational program available to en- sure that our engineers have a sharper ship design vision by maintaining state-of-the-art knowledge and skills, both theo- retical and experimental."

He said further: "The import- ance of timely technology trans- fer is evident by the many ad- vances in our Navy's Fleet which have evolved over the years from

NAVSEA's hydrodynamics R&D programs. Many of you here to- day personally contributed to these advances. We are all aware of the high-speed submarine hull forms, higher speed torpedoes and improved underwater launch systems. To this we could add skewed propellers for reduced ship vibrations, improved subma- rine maneuvering and control, re- liable submarine emergency re- covery procedures, and many others. More recently, the appli- cation of seakeeping technology to surface ship designs has sig- nificantly contributed to improv- ing the performance of future naval ships as well as those in the Fleet today."

In summary, Admiral Lisanby said: "SEAHAC plays a most valuable role in the acquisition of technically innovative ships and weapons by pointing the way in the hydromechanics research.

A concerted effort by SEAHAC is essential to predicting the fu- ture Fleet requirements, identi- fying the present technical ob- stacles, and developing the re- search programs to overcome them."

R.O. Walters Appointed

Vice President For

Ryan-Walsh Stevedoring

Ryan-Walsh Stevedoring Com- pany, Inc. of New Orleans has appointed Royston O. Walters a vice president. He joined Ryan-

Walsh in May 1980 as general manager of port programs and planning at New Orleans. His du- ties will continue essentially un- changed.

Mr. Walters has compiled a 26- year background in bulk handling facilities, including planning, con- struction, and management, and has served past employers as gen- eral manager, vice president, and president. Prior to joining Ryan-

Walsh, he was general manager in New Orleans for TTT Steve- dores of Louisiana, Inc. His ca- reer in bulk terminal manage- ment began in 1954 with a New

Jersey firm, for whom he achieved a 400-percent growth factor.
