Efthimiou, president of Sigma Treatment Systems, Inc. of New York, N.Y., has announced the signing of a joint venture agree- ment with the Hellenic Shipyards, Skaramanga, Greece, for the fab- rication of Sigma Disposal Systems and other pollution equipment by Hellenic Shipyards for the Eastern Mediterranean area. A formal contract was signed at the Posidonia Exhibition held in Piraeus, Greece. Pictured above, left to right: G.B. Efthimiou, president, Sigma Treatment Systems, Inc.; M. Triantafyllides, technical man- ager, Hellenic Shipyards, Skaramanga, Greece; C. Caldis, managing director, Hellenic Shipyards; W.F. Roberts, design consultant, Sigma Treatment Systems, Inc., and E. Konstas, managing director, Tech- nomar, Co., Ltd., representative for Sigma Treatment Systems, Inc., in Greece. Powered by a pair of GM Detroit Diesel Allison 6-71s, the Tappan Zee II was designed and built by Gladding-Hearn for her many and varied duties associated with the maintenance of the Tappan Zee Bridge. Gladding-Hearn Shipbuilding Corporation, 1 Riverside Avenue, Somerset, Mass. 02725, recently announced the delivery of an all- steel 48-foot by 16-foot tug, Tap- pan Zee II, to the New York State Thruway Authority. There is re- ally nothing spectacular about the boat—it's just a plain, sturdy tug, built to American Bureau of Ship- ping + 1 classification. Preston R. Gladding, the tug's designer, made her look like a small tug should, with proper shear and jaunty visor. Power selected was a matched pair of General Motor Detroit Diesel Allison 6-71s, the old reli- able work horse of the marine in- dustry. A small Onan 110 a-c gen- erator is also set in the engine room for supplying a-c power to hand tools used in bridge main- tenance. Due to the exposure of munici- pal purchasing and quality assur- ance, the Authority took every precaution by specifying Tappan Zee II to be built to American Bureau of Shipping classification. George G. Sharp, Inc., naval ar- chitects of New York, N.Y., also represented the Authority during construction. Although the tug may seem conventional, her duties are var- ied and interesting. The three-mile-long Tappan Zee Bridge has 16,000 wood cluster piles around each bridge pier for icebreaking purposes, essential protection against the large ice flows coming south down the Hudson River. The maintenance of these piles is a never-ending maintenance chore serviced by two full dock-building crews and two lighters—the Tappan Zee II handles the lighters and crew transfers. Because the Hudson River bed cannot support the total bridge load, the main bridge supports are semi-buoyant concrete cais- sons fitted with bilge pumps which must be maintained and in- spected frequently, regardless if ice conditions exist. Occasionally, a motorist will flick a lit cigarette off the bridge and the pile clusters will catch fire, therefore the tug is equipped with a 500-gpm firefighting moni- tor and pump for this emergency. Although the Authority high- way service trucks are equipped with firefighting apparatus, the Tappan Zee II can also spray foam on the roadway above with greater compatibility than the fire trucks, if an oil truck should catch fire.
