foundation. A slewing ring fitted to the base is capable of sustain- ing vertical load and tilting mo- ment. The jib is a steel fabrica- tion incorporating the bearings for the pivot pins on the yoke and sheaves for the wire ropes. For transfer of oil at sea, Schat has developed its "Flow Boom" crane that handles single or twin hoses, with operating enve- lopes that consider the relative positions between ship mani- folds. Flow capacity for crude oil through 20-inch hose is 6,000 tons per hour; through 24-inch pipe construction flow boom, capacity is 12,000 tons per hour. Flow ve- locity is 48 feet per second at pressures up to 150 psi. TBW INDUSTRIES Versatility has never been more in demand in the maritime indus- try than it is today, and this is what characterizes TBW Indus- tries' philosophy in the develop- ment and marketing of its deck Write 257 on Reader Service Card machinery products for the 1980s, according to Robert M. Thomp- son, president of the Houma, La. company. The products of TBW's SMAT- CO Division have long been syn- onymous with the offshore indus- try. Its original line of equipment centered around anchor-handling/ towing winches. Within a short time span in the early 70s it had expanded to include a complete line of machinery ranging from anchor windlasses to stern rollers. As the quest for oil moved from the calm, shallow waters of the Gulf of Mexico to the harsh environment of the North Sea and the deepwater exploration in Southeast Asia, SMATCO earned its reputation for toughness and durability. It is this type of work that led SMATCO to its latest development: caliper/disc brakes and clutches. The refinement of this system has opened new op- tions to the operator faced with the tasks of heavier loads in deeper waters. Taking the heart of the brake system to task, SMATCO now offers disc brakes on all of its winches and related equipment. Another advancement in the state of the art has been the de- sign of a double-drum waterfall winch designed especially for tug- boats. Traditionally, waterfall winches were unacceptable be- cause of height. SMATCO's new low-profile winch has eliminated this major problem and at the same time reduced the overall width by nearly 50 percent. This offers the operator a larger and safer working area, as well as the advantage of always working closer to the center line of the vessel. Recognizing the U.S. maritime industry as an area needing the same level of quality as the off- shore oil operators, SMATCO launched an effort to become a sought-after supplier. Since its initial effort in 1978, the com- pany has secured mooring equip- ment orders from major ship- yards such as Sun Ship, NASSCO, Avondale, Newport News, and General Dynamics. Ships include RO/'ROs, product carriers, and dredges. A further development has been the SMATCO-Samson range of soft rope, twin capstan type trac- tor winches.
