Puroflow Marine Introduces New

Integrated Power-Line Protection

System—Literature Available

Puroflow Marine Corporation, Newport

News, Va., has announced the development of a centralized power-line protection system for shipboard electronics. It is the industry's first comprehensive, integrated package for protec- tion of a ship's total electronics suite against harmful voltage surges and electromagnetic in- terference (EMI).

Puroflow's new system includes a central con- trol panel, which provides convenient remote monitoring of multiple circuits, plus as many as 75 separate power-line filters, which may be installed throughout the ship's power lines as needed. Thus, all bridge, radio-room and en- gine-room electronics can be linked into a single integrated system.

According to G. Howard Warren, vice pres- ident of marine marketing, Puroflow has taken the industry's first truly integrated approach to solving the problem of "dirty" power aboard ship, rather than the usual piecemeal solution, in which filters or suppressors are added here and there aboard ship when problems occur. "The marine industry is becoming more aware of the vital need for adequate power-line protec- tion for modern marine electronics," Mr. War- ren stated. "Voltage surges can have devastat- ing effects on solid-state circuitry, causing elec- tronic devices to 'lock up' without warning, los- ing data in memory and giving faulty output to other devices. As ships become more dependent on sophisticated computer-based electronics for navigation, communication, automation and monitoring, it becomes imperative to take a comprehensive approach to power-line protec- tion."

Puroflow's new system provides centralized control and monitoring of up to 75 separate surge suppressors. Lights and audio alarms alert ship's crew to problems anywhere in the electri- cal system. Crew members can quickly identify and isolate problems and effect repairs without manually tracing through scores of circuits. This assures minimum downtime for essential elec- tronics, which may be needed for safety at sea.

Puroflow developed the new centralized sys- tem from a prototype originally created for a

U.S. Navy installation, which had been experi- encing serious problems with outages resulting from lightning. Other approaches to solving the problem had proved ineffective. The Puroflow system was 100 per cent successful in eliminat- ing outages, and the Navy is placing orders for additional systems, according to Mr. Warren.

Puroflow is a leading manufacturer of power- line protection devices for the commercial and military marine industry. The company's prod- ucts have been independently tested to meet the most stringent requirements for voltage surge and noise protection, meeting all U.S. Navy specifications, including those for shock and vibration.

Navy's New Double-Deck Pier To

Be Fitted With Sea Guard Fenders

A new double-deck pier has been designed to meet the changing needs of U.S. Navy ships, and

Navy engineers believe it could become the pro- totype for worldwide Navy facilities.

Known as Pier Zulu, the facility will be built at the U.S. Naval Station in Charleston, S.C., and will be outfitted with 16 of Seaward Inter- national's 7- by 14-foot Sea Guard dock fenders.

These fenders are constructed of the same ener- gy-absorbing foam interior, covered with a rug- ged urethane, filament-reinforced jacket, as all of Seaward's marine fenders.

Pier Zulu will be a concrete structure 1,245 feet long and 76 feet wide, compared with con- ventional pier width of 100 to 120 feet. The cost for the new pier will be slightly higher than a conventional-width, single-deck structure, but less maintenance and more efficient operations are expected to reduce its long-term cost to the

Navy.

The upper deck of the pier will be eight feet higher than conventional piers—about 20 feet above mean low water level—providing easier access to the quarterdecks on new Navy ships.

The lower deck will contain utility outlets, cables, and transformers in order to make line handling and equipment and vehicle operations easier. It will also be accessible to pickup trucks and forklifts to allow maintenance and repair of utility services, leaving the upper deck free for ship and pier operations.

Pier Zulu was designed by Gee and Jenson

Engineers of West Palm Beach, Fla., in conjunc- tion with the Southern Division of the Naval

Facilities Engineering Command. H.G. Harders and Sons of Charleston will construct the pier, which is scheduled for completion in March 1986.
