40 ST | June 2018 www.sea-technology.com Electric Workboats Clean Up Suzhou River The City of Suzhou in eastern China has deployed a fleet of elec- tric workboats powered by Torqee- do motors as part of a program to clean up its canals and waterways. Suzhou is home to more than 10 million people. The 2,500-year-old city is noted for its many canals, rivers, lakes, ancient stone bridg- es, pagodas and gardens. Suzhou Creek, which flows through the city to Shanghai, was at one time said to be the most contaminated waterway in China. Over the past decade, the river has undergone a major trans- formation and is an acclaimed envi- ronmental success story. As part of the cleanup program, the Suzhou River Management Ad- ministration commissioned the con- struction of 177 vessels designed specifically to remove floating de- bris from the water. The adminis- tration specified electric-powered boats for the project because of their environmentally friendly foot- print, and after a competitive evalu- ation the builder selected Torqeedo to supply electric motors. Torqeedo has now completed outfitting the entire fleet, which includes 18 9-m steel catamarans with twin Cruise 4.0 outboards, 22 7-m steel catamarans with twin Cruise 2.0 outboards and 137 5/6- m wooden boats with Cruise 2.0 outboards. The boats were designed and built by China Ship Scientif- ic Research Center, owned by the Suzhou River Management Admin- istration and operated by private contractors. Partnership for Advanced Machine Learning Subsea Acteon Group and Arundo An- alytics announced a partnership to deliver machine learning models for subsea applications on the Arundo Enterprise platform. Using its in- dustry insight and subsea expertise, Acteon, will work with Arundo as one of its preferred partners to de- velop high-value advanced analyt- ics for its operating companies. This will be used to support its global customer base, using tools includ- ing machine learning and artificial intelligence to help reach Acteon's ambition of reducing the cost of as- set ownership by 30 percent. Ashtead Adds SPRINT-Nav To Rental Fleet Ashtead Technology has select- ed acoustic and inertial navigation technology from Sonardyne Interna- tional Ltd. to add to its rental fleet. The multiple SPRINT-Nav systems will be made available to support survey and construction projects us- ing ROVs and AUVs in water depths down to 4,000 m. SPRINT-Nav makes optimal use of acoustic aiding from data sourc- es including USBL, sparse LBL and DVL and pressure sensors to im- marine electronics
