44 st / September 2017 www.sea-technology.com Designed to Polar Class 6 standard, New Zealand's future fleet replenishment tanker can operate in Antarctic waters. SonarPoint for Cetacean, Noise Studies And Boat Tracking Desert Star Systems has introduced SonarPoint, a por- table system for the detection and localization of sounds in the ocean. Funded by the Marine Mammal Program at the U.S. Office of Naval Research (ONR), SonarPoint is designed primarily to study the abundance, migration and behavior of cetaceans. SonarPoint is also suitable for tasks such as the study and mitigation of noise associated with underwater industrial activity and the detection and track- ing of small craft to combat smuggling, piracy or poaching. A typical SonarPoint system comprises four recorders. Several task-specific deployment modes include ocean drifters for rapid deployment of a temporary tracking array, moored with surface buoy and solar power for semiperma- nent monitoring at critical sites, and seafloor with acoustic release and without surface expression for long-term moni- toring at deep or high-traffic sites and when clandestine op- eration is needed. In testing in the San Juan Islands of Washington, Sonar- Point demonstrated both ease of deployment from a RIB boat and the ability to localize vocalization of killer whales and test signals with an accuracy of a few meters. Canada Awards Contract To Recycle Two Navy Ships The Government of Canada awarded a $12.6 million contract to Marine Recycling Corp. from Port Colborne, On- tario, for the disposal of two Royal Canadian Navy's ships. The dismantling is expected to be completed by summer 2019. The contract includes towing to the contractor's fa- cility in Nova Scotia, demilitarization of equipment, reme- diation of hazardous waste and recycling of any remaining materials. US Coast Guard Resumes Shipboard Dive Operations in Arctic U.S. Coast Guardsmen and U.S. Navy sailors have con- ducted shipboard dive operations from a Coast Guard cutter in the Arctic for the first time since two Coast Guard divers perished in a subsurface accident almost 11 years ago. In the years following the accident, the Coast Guard im- proved diving proficiency and retention by making diving a primary duty and created the first three regional dive lockers to centralize control, training and operations. The joint dive operation from Healy in July marked the culmination of this increased oversight, training and proficiency. The crew of the Healy and joint dive team held a me- morial to honor the fallen divers during the cutter's current Arctic patrol. MacArtney Winch for Pakistani Naval ROV Operations MacArtney has supplied a custom-engineered winch sys- tem to a South Asian defense contractor that will become part of the ROV equipment for the Pakistani Navy. The winch came with a 3,000-m fiber cable and termina- tion. The traction-based winch has been purpose-built for use with a customer-built ROV designed for localizing ob- jects on the ocean floor. ST Klein 5900 Sonar Images Italian WWII Sub Klein's flagship 5900 high-resolution, high-speed side scan sonar, which can be a conventional towed system or a payload for an unmanned surface vehicle (USV), was re- cently tested with its newest features in Israel on the USV Seagull, Elbit's platform for mine hunting and anti-subma- rine warfare. Among the features is the ability to control and stream full-resolution sonar images via satellite. The Klein 5900 made several passages over the wreck of the Italian submarine Scirè, sunk by a British naval trawler in 1942. The sub lies in 35 m of water on a sandy bottom, 6 mi. outside Haifa. LR, HHI Partner to Prepare Safety Case for New Zealand Navy Lloyd's Register (LR) is working with Hyundai Heavy Industries Co. Ltd. (HHI) on the preparation of the safety case for the Royal New Zealand Navy's (RNZN) maritime sustainment capability (MSC) project, which is taking place in Ulsan, South Korea. The MSC project will replace the RNZN's aging HMNZS Endeavour tanker. The new vessel is intended to strengthen maritime replenishment capability at sea by supporting the nation's naval combat force and its partner countries' ships. The tanker is also suitable for logis- tics support, maritime sustainment, humanitarian aid and disaster relief. navy currents
