www.sea-technology.com September 2017 / st 43 The National Deep Sea Center will deploy scientific equip- ment to depths of 6,000 m below the surface to gather data from the sediment and surrounding subsea environment. Once the study is complete, RJE will recover the equipment mooring using its ATT-400/6KM acoustic transponder and STI-350 surface acoustic receiver, if the equipment surfaces far from its original location. FarSounder Long-Range Sonar Added to RRS Sir David Attenborough FarSounder's longest-range sonar system, FarSound- er-1000, will be incorporated into the British Antarctic Survey's new polar research vessel, the RRS Sir David At- tenborough. On long voyages to remote aquatic regions, FarSounder sonar will provide navigation and obstacle avoidance, as well as gather data beyond that provided by traditional onboard science mission sensors. Harvest is the First Complex Liquefied-Ammonia Transport Barge Built in the US Since 1982 Harvest is an articulated tug barge (ATB) built to transport liquefied anhydrous ammonia. It has been classed by ABS Global Gas Solutions and delivered to a subsidiary of Sav- age Companies by U.S. shipbuilder Vigor. Harvest will support the Jones Act trade of Tampa Port Services LLC, a subsidiary of The Mosaic Co., a producer and marketer of concentrated phosphate and potash. The ATB will carry up to 22,000 tons of anhydrous ammonia (NH 3 ), a key ingredient in phosphate-based fertilizer. American Waterways Operators Launches Study On Economic Contributions of the Barge Industry Developed through a cooperative agreement between AWO and the U.S. Maritime Administration (MARAD) and conducted by PricewaterhouseCoopers, the study docu- ments the contribution of the American tugboat, towboat and barge industry to the U.S. economy. The study explores contributions to employment, gross domestic product and taxes; details commodities transported; and compares wa- terborne transport to other modes of freight transport. Advanced Tugboat Simulators Now Operational At MITAGS-PMI The Maritime Institute of Technology and Graduate Stud- ies/Pacific Maritime Institute (MITAGS-PMI) expanded its tractor-tug simulation facilities to integrate up to four assist- tugs and two full-mission bridges in one exercise. The Transas NT Pro 5000 has improved hydrodynamic modeling and interaction for training in offshore operations, ship assist, high-speed escort, anchor equipment operation, platform moves and tug master and pilot training. The two additional tug bridges also benefit the Navigation Skills As- sessment Program (NSAP), tanker escorts, tug and barge op- erations, ARPA and ECDIS training program. ASL to Represent DeepWater Buoyancy ASL Environmental Sciences Inc. will represent Deep- Water Buoyancy in British Columbia, Alberta and Alaska in sales of buoys and flotation systems and solutions for moor- ing and oceanographic instruments. ASL offers support for mooring design, deployment and data analysis and post- processing.
