42 ST | November 2018 Ocean Infinity Signs Agreement with US Naval Meteorology and Oceanography Command Ocean Infinity has signed a cooperative research and development agreement with the U.S. Naval Meteorolo- gy and Oceanography Command (NMOC), based at the Space Center in Stennis, Mississippi. During the next five years, the collaboration will focus on combining and ex- panding technologies relating to a broad range of deep- water platforms and sensors focused on undersea data gathering and analysis. Damen Marine Components to Supply Chilean Navy Polar Vessel Damen Marine Components has won a contract to supply steering gear, rudders and stern tube parts for an Antarctic research vessel of the Chilean Navy, under LRS -Polar 5 class notation. The contract was awarded by AS- MAR Talcahuano Shipyard, Chile. Design of the vessel was done in collaboration with VARD Canada. Damen Marine Components will supply twin COM- MANDER Ram-Type electrohydraulic steering gear units, twin ATLANTIC semi-spade rudders and twin stern tube casting parts. The equipment will be delivered in 2020. The vessel is scheduled to set sail on its maiden voyage to the Antarctic Polar Circle in 2023. Students Demonstrate Skills In Autonomous Subs and Presentation The International RoboSub Competition took place in San Diego at the Space and Naval Warfare Systems Cen- ter Pacific Transducer Evaluation Center. The week-long autonomous submarine competition is co-sponsored by the U.S. Office of Naval Research (ONR) and the Asso- ciation of Unmanned Vehicles International Foundation. All submarines must demonstrate autonomous capability by completing a series of visual- and acoustic-based tasks that simulate duties required of underwater vehicles. To meet this year's mission requirements, the subma- rines—without human or computer interaction—had to complete "casino-themed" tasks including: touching dice buoys; dropping chips into a roulette bin; pulling a slots lever to fire mock torpedoes through small cutout holes; and cashing in by grabbing a chip, then surfacing the vehicle and dropping the chip into a cashier's regis- ter. Teams also had to create a website, write a paper that outlined their work and give a presentation. Harbin Engineering University (China) took this year's top prize, while National University of Singapore and École de Technologie Supérieure (Canada) placed sec- ond and third, respectively. DVL for US Navy Micro-UUV Teledyne RD Instruments' (TRDI) new ultracompact 600-kHz Pathfinder DVL has been selected by Riptide to provide precision navigation capability for its micro-UUV for the U.S. Navy. The DVL, coupled with an iXblue INS, will deliver a 200 percent increase in navigation perfor- mance with minimal impact on vehicle endurance. eMARINE to Continue Servicing Korean Navy eMARINE Global Inc. announced the extension and expansion of its maintenance contract with the Republic of Korea (ROK) Navy for work through 2019. eMARINE Global has been servicing the ROK Navy continuously for nine years, providing routine, preventive and emer- gency maintenance, as well as chart updates for the elec- tronic charts display and information systems (ECDIS) onboard Korean naval vessels. The latest contract extends this relationship and expands it to more than 213 vessels. Combat Diver Navigation System For Poor-Visibility Environment JFD, part of James Fisher and Sons plc, has partnered with the U.S. Navy's Naval Surface Warfare Centre – Pan- ama City Division (NSWC PCD) to develop an advanced combat diver navigation module, Shadow NAV, bringing a hands-free underwater navigation capability to the mil- itary market for the first time. Military combat divers frequently conduct underwa- ter navigation missions in hazardous conditions with ex- tremely poor visibility. Accurate underwater navigation is critical, as well as staying within closed-circuit oxygen rebreather depth limits to prevent oxygen toxicity. The Shadow NAV ensures combat divers have continuous visibility of accurate information with a mask-mounted head-up display. ST navy currents
