riod and much effort, both the Vi- king davit-launchable and the regular throw-overboard rafts now have USCG approval and are readily available in the U.S. In addition to the 20- and 25- person liferafts that were avail- able in the past, Viking now offers 12- and 16-person davit-launcha- ble rafts, designed primarily for the smaller oil rigs and smaller cargo vessels that would not nec- essarily require the larger capac- ity rafts. Viking conventional throw-overboard type liferafts are available with capacities from four to 25 persons. Viking (America)s parent com- pany is Viking-A/S Nordisk Gum- mibaadsfabrik located in Esbjerg, Denmark's major West Coast port. A private company founded in 1960, Viking A/S has specialized in the production of life-saving equipment for the marine and aviation industries. The company's range of products includes auto- matic inflatable liferafts, fiber- glass-reinforced lifeboats (open and totally enclosed versions), lifejack- ets, and other life-saving appli- ances. Viking products are recog- nized and approved by most of the national shipping authorities and classification societies worldwide. To provide comprehensive serv- ice backup for the Viking prod- ucts, subsidiary companies have been established in England, Netherlands, Norway, Singapore, and the U.S. In addition to the network of sales agents, there are 155 approved Viking servicing sta- tions in major ports around the world; 22 of these are in the U.S. Editor's note—Much of the ma- rine survival and safety equip- ment purchased in the U.S. is marketed by manufacturers' rep- resentatives and authorized dis- tributors.

The marine tendering system, called Delta, designed by Uniroyal, Inc., and installed by NORSHIPCO, satisfies high en- ergy absorption and long life requirements. George Curtis, NORSHIPCO vice president, Facilities Engi- neering, explained: "We needed a tendering system that could ret- rofit onto our existing pier and pil- ings. It had to withstand very high impact and pressure loads." Uniroyal tendering specialists, working closely with Seaport Sup- ply engineers, recommended Model 28A dual-mounted Delta fenders which provide double the energy absorption capability of single Delta modules without increasing the reaction force on the pier. This self-supporting, self-contained sys- tem, consisting of eight fender as- semblies, was installed at the pier site in a period of less than six months. The dual mount design enables complete access to a ship's hull be- cause the fender modules have a 48-inch stand-off from the pier. "The fenders have provided the necessary protection to both the over-hauled ships and the pier," said Mr. Curtis. The 12 dual-mounted Delta A fenders used at NORSHIPCO can service ships which have a dis- placement tonnage of 50,000 to 58,000 tons. The Delta dual- mounted fender provides an excel- lent Reaction to Energy (R/E Fac- tor) of only .70. As a result, any fender pressure on the hull of a ship which has that displacement tonnage normally will not cause surface damage to the ship. Each 12-1/3-foot-long fender as- sembly, consisting of three Model 28A dual-mounted Delta fenders, has an energy absorption rating of 458 kips/foot and can withstand a load of 31.5 kips/foot. The fenders are extremely flexible and will de- flect more than 24 inches without permanently damaging or altering the Delta fender shape. Uniroyal, Inc. manufactures the Model 28A Delta fenders used at the NORSHIPCO pier from a spe- cially developed EPDM/butyl com- pound that combines butyl's excel- lent damping capabilities with EPDM's superior heat and weath- ering properties. The Delta dual-mounted fenders consist of two single Delta fender modules, each two feet long and 3V4 inches wide. These two mod- ules are bolted together with a 19-inch-long, IVi-inch-diameter threaded steel rod. The three dual-mounted fenders Circle 197 on Reader Service Card 31 used in each assembly are covered with 12-1/3-foot-long spaced-tim- ber facings that evenly distribute a ship's load against the fender assembly.

All Clow/Green- berg valves and fittings are man- ufactured in accordance with mili- tary quality control specification MIL-1-45208A. The brochure describes, with drawings and tables of specifica- tions, globe, angle, check, gate, and hose valves. It also contains details on Macomb strainers, voice tube fittings, fueling spools, flanges, handwheels, and hub blanks, as well as a reference list. The company dates back to 1854 when Morris Greenberg, newly migrated to California from his native Paris, opened his own foundry in San Francisco. From this humble beginning, the busi- ness prospered, and he manufac- tured nozzles for hydraulic mining and bronze spikes for sailing ships. One of Greenberg's most well- known products was the "Califor- nia Type" fire hydrant that Morris Greenberg developed and manu- factured with the aid of the San Francisco Fire Chief.
