56 st / April 2017 Canadian Arctic Shipping Risk Assessment System The Arctic makes up 40 percent of Canada's landmass. The government of Canada, with help from the National Research Council of Canada (NRC), is supporting navigation in the Arctic with NRC's Canadian Arctic Shipping Risk Assessment System (CASRAS), an integrated software system that enables sound decision making for safer and more efficient shipping through the Arctic. The system provides comprehensive environmental data, including marine weather; hydrography; physical ocean- ography; sea ice conditions, hazards and physical properties; marine pro- tected areas; and historical informa- tion on winds, waves, tides and ice forecasting. It is suitable for shipping companies, regulators, government departments, ice navigators, northern communities, insurance companies and academia. Forum ROV Simulator for California Science Center Forum Energy Technologies Inc. has delivered a custom-built simulator to California Science Center to provide visitors with the experience of operat- ing an ROV. The core technology is Fo- rum's VMAX ROV Simulation Software, modified to allow the virtual ROV to be flown without prior experience. The exhibit features two simulation stations, each with a main joystick to control the ROV and a second smaller controller that operates the ROV's on- board manipulator. Modus Completes Hybrid UUV System Integration, Trialing Modus Seabed Intervention has completed system integration and tri- aling of a hybrid UUV for survey and inspection projects in the offshore, defense and oceanographic sectors. Working with Saab Dynamics, Modus has developed the Saab Sabertooth specification for greater endurance and speed, and is developing advanced sensor payload packages and operat- ing methodologies. Having completed integration tests and trialing in Sweden and the U.K., the company is preparing the advanced spread for its first com- mercial deployment. The vehicle has increased thrust for high-speed survey and additional batteries for endurance. The first vehicle is depth rated to 1,200 m, which can be upgraded to 3,000 m. Virtual Shark Net Around City Beach Tritech International Ltd. has suc- cessfully deployed its first full-beach shark detection system in collabora- tion with Shark Mitigation Systems Ltd. (SMS). The Clever Buoy system is active at City Beach in Perth, Australia. Each Clever Buoy is solar powered and utilizes a PC running the jointly de- veloped SharkTec software, with three sonars creating a continuous area of coverage. When the SharkTec software identifies a shark, a message is sent to onshore via the Clever Buoy app and is integrated into emergency services messaging to the public. City Beach now has two Clever Buoys active, each with three sonars, creating a "virtual shark net" around the beach. First Live Video of Underwater Snake Robot Eelume AS has released the first live video footage of the new Eelume robot, developed with Kongsberg Maritime. The snake-like vehicle is designed to live permanently underwater and carry out underwater intervention tasks that would normally require the mobiliza- tion of expensive vehicles. The footage captured at the PREZIO- SO Linjebygg Subsea Test Center dur- ing trials in the Trondheimsfjord shows the potential of the Eelume vehicle to significantly improve inspection and light intervention operations on subsea installations. The modular, snake-like design allows the Eelume to access hard-to-reach points on subsea struc- tures and shift into a U-shaped dual arm configuration. Illumination Device Reduces Turtle Bycatch Hundreds of thousands of sea turtles are accidentally killed by fishing gear every year. John Wang, an ecologist for NOAA, came up with an idea for an illumination device and submit- ted it to the WWF International Smart Gear Competition, which encourages innovative ideas for reducing bycatch in fisheries. Turtles can see certain light wavelengths that a lot of fish species can't. Wang's theory is that if you use a light with the right wavelength, you could help turtles see and avoid the nets, while still catching fish. The test results showed up to a 60 percent re- duction in turtle bycatch and a 20 per- cent boost in the target catch for par- ticipating fishers. WWF and NOAA are now working with a small company to develop a better case for the light and are exploring the potential of further testing. Trimble to Distribute Version Of Teledyne PDS Software Trimble will distribute a branded version of Teledyne's PDS software package for hydrographic survey, con- struction and dredging operations: Trimble Marine Construction Software. It provides accurate measurement and positioning to improve marine con- struction efficiency and safety. The soft- ware offers real-time sensor data gath- ering, computation, display and logs. The data can be displayed graphically or alphanumerically. It has options to verify the data and remove anomalies and outliers. The clean data can be presented as models, tables, files, vol- umes, nautical charts or reports. The software is expected to be available in the second quarter of 2017. Sonar Systems Enable Extensive Marine Studies A variety of sonar systems are now being used by law enforcement and public safety dive teams, universities and salvage companies for recovery operations, subsea surveys and marine research. These systems help save time and money, increase diver safety, and allow more extensive study of the ma- rine environment. An example is the JW Fishers SBP-1 sub-bottom profiler, being used to locate cargo containers buried at the bottom of China's Yang- tze River. Also in China, JW Fishers SSS-100K/600K side scan sonar and the SeaLion-2 ROV are being used for research on how changes in the ocean environment affect marine life in the East China Sea. In Hong Kong, William- son Marine Service recently acquired a JW Fishers SCAN-650 scanning sonar for applications such as ROV naviga- tion, bottom scanning and diver guid- ance.
