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 oceanography; sea ice conditions, hazards and physical properties; marine protected areas; and historical information 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 operating an ROV. The core technology is Forum’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 onboard manipulator.

Modus Completes Hybrid UUV
System Integration, Trialing

Modus Seabed Intervention has completed system integration and trialing 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 operating methodologies. Having completed integration tests and trialing in Sweden and the U.K., the company is preparing the advanced spread for its first commercial 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 successfully deployed its first full-beach shark detection system in collaboration 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 developed 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 mobilization of expensive vehicles.

The footage captured at the PREZIOSO Linjebygg Subsea Test Center during 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 structures 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 submitted 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 reduction in turtle bycatch and a 20 percent boost in the target catch for participating 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, construction and dredging operations: Trimble Marine Construction Software. It provides accurate measurement and positioning to improve marine construction efficiency and safety. The software offers real-time sensor data gathering, 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, volumes, 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 marine 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 Yangtze 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, Williamson Marine Service recently acquired a JW Fishers SCAN-650 scanning sonar for applications such as ROV navigation, bottom scanning and diver guidance.
