Two Speakers Address

Pacific NW SNAME

Annual Student Meeting

The annual student meeting of the Pacific Northwest Section of

The Society of Naval Architects and Marine Engineers, recently held at the Windjammer Restau- rant in Seattle, Wash., was a huge success. Sixty-one regulars and 61 students jammed the room to hear

Dr. J.R. Paulling of the University of California, and Godik Gyldenge of Industrial Underwater Services,

Inc., the speakers for the day.

Dr. Paulling is professor of na- val architecture and department chairman at Berkeley. His talk was termed "Studies of Ships Capsizing in Heavy Seas." Dr. Paulling's report was based on tests conduct- ed using radio-controlled self- propelled models. As part of his presentation, a film was run show- ing the capsizing in "heavy seas" of a large containership model in

San Francisco Bay. Discussers were Lawrence Glosten of L.R.

Glosten and Associates, and Cecil

Shaver of Nickum & Spaulding

Associates, Inc.

This study was funded by the

United States Coast Guard, Office of Research and Development, with

Coast Guard personnel assisting in the experiments. The results have greatly aided in the development of understanding of the mechanism of capsizing and have defined areas on which to focus future work.

In the second session of the day,

Mr. Gyldenge introduced Con- trolled Dynamics Corp.'s Sequen- tial Sea Mesh Hull Cleaning. This method employs a low-level explo- sive mesh-like structure hanging down parallel to the vessel's under- water body. Shock waves produced by the electrochemical disintegra- tion of the mesh produces water pressure waves, sweeping the ma- rine fouling from the hull without damage to the paint system. This type of hull cleaning introduces considerable savings over the con- ventional drydocking. It is fast, economical and should produce sig- nificant savings in vessel fuel con- sumption due to the reduction in drag caused by -marine growth.

Dr. Albert A. Pence, senior phys- icist at the Applied Physics Labor- atory of the University of Wash- ington, assisted Mr. Gyldenge in his presentation by explaining to the group some of the more sci- entific aspects of the method.

Uniroyal has a complete line of MARINE FENDER

SYSTEMS like the new Delta fender shown here, to absorb shocks and prevent docking damage.

Uniroyal's Butyl/EPDM fenders don't just stand up to ships . . . they resist heat, corrosion, marine growth and adverse weather too.

There's a configuration for every need. We've done extensive engineering studies and computations on fender assemblies ... we know what's best for a given installation . . . we'll tell you exactly what you need and why. New, jumbo sizes are currently under development for your future needs.
