Ocean Specialty To Charter U.S.-Flag Product Carriers From OMI, Hvide Shipping Ocean Specialty Tankers Corpo- ration (OST), a newly formed Hous- ton-based company, recently an- nounced an agreement in principal to long term charter three modern U.S.-flag parcel vessels from OMI Corporation and Hvide Shipping, Inc. The vessels, OMI Dynachem, OMI Hudson and Seabulk Magna- chem, are all in the 40,000 to 50,000 deadweight tonnage range. It is planned that OST will acquire cer- tain assets and business interests from Seabulk Ocean Systems Cor- poration, an Hvide Shipping affil- iate, and OMI Corp., and will ex- pand on existing bulk liquid parcel services to U.S. East and West Coasts. Additionally, OST has agreed to charter the Seabulk Amer- ica, which is expected to undergo reconstruction shortly in a U.S. shipyard. The Seabulk America will add 41,000 deadweight tons of new capacity to the Jones Act parcel trade. The unique aspect of the Sea- bulk America is that she has a sig- nificant amount of stainless steel capacity. OMI Inc. is a publicly held major bulk shipping company operating in both the international and U.S. domestic markets. Hvide Shipping, Inc., is a private- ly held U.S. flag owner and operator with significant interests in the shipping industry. >r a n d a 11 CONSULTING SERVICES & DESIGN FOR: MARINE RAILWAYS FLOATING DRY DOCKS WATERFRONT STRUCTURES • INSPECTION • CERTIFICATION • DIVING SERVICES • DRY DOCK HARDWARE Since 1854 CRANDALL DRY DOCK ENGINEERS, INC. 21 Pottery Lane Dedham, Massachusetts 02026 Telephone (617) 329-3240 Telex 924406 (CRADOODEDM) Circle 251 on Reade: Service Card Space saving physical/ o^ a ' chemical design * * requires 90% less space ^ than biological systems.

IL) Acurex Sea Trials Meter Provides User With Complete Versatility The Acurex Sea Trials Meter has torque and horsepower scaling adjustment controls ac- cessible from the front, allowing display scaling at any time, even while underway. Acurex Corporation/Autodata Di- vision, Mountain View, Calif., is a manufacturer of measurement and test equipment for surface and un- dersea ships of the U.S. Navy and other navies around the world. The Acurex Model 1605A Univer- sal Sea Trials Meter for the first time combines the proven Acurex (torque) Deflection Sensor P/N 10021, with lightweight clamp rings, and the new Model 1645A Field Adjustable Readout Electronics. This combination provides the user with the complete versatility of be- ing able to use the same electronics and sensor for any ship with the sig- nificant benefit of last minute scale factor adjustment onsite and the capability of fully checking those adjustments at any time without stopping the shaft. The sensor is calibrated for a range of deflection which, coupled with the switchable calibration fea- tures of the receiver (DEMOD) card allows the user to set up the Sea Trials Meter for any torque or pow- er level on any ship. Torque and horsepower scaling adjustment con- trols, accessible from the front, al- low display scaling at any time, even while underway. Ships power, shaft parameters and clamp ring dimensional param- eters establish the sensor deflection under operating conditions. The ra- tio of operating deflection and sen- sor calibration is set into the read- out using a voltmeter and screw- driver at the front panel. Display scaling is also set with a screwdriver and these scaling factors can be checked at any time.
