Also in June, UTEC announced it had taken the delivery of a second Gavia AUV from Teledyne Gavia (Kópavogur, Ice- land) to be used for commercial survey applications. In 2011, UTEC received its first Gavia AUV and, following successful surveys with the AUV in South America, ordered the second, which was delivered in the first quarter of 2012. Phoenix International Completes Hull Work On USS Midway, Acquires Bluefin-21 AUV Phoenix International Holdings Inc. (Largo, Maryland) has completed improvements to the hull integrity of the museum ship USS Midway in San Diego, California, the company an- nounced in July. Phoenix divers used a new Ameri can Weld- ing Society-approved wet-welding procedure to patch more than 319 hull openings. Starting in 2010, work took place each spring. Performing work underwater allowed museum operations to continue while avoiding the large expense of dry-docking. The new wet-welding procedure used a more efficient and readily available electrode able to weld to the higher carbon steel in the Midway's hull. Divers welded 2,098 linear feet of wet welds over 5,300 hours of incident-free bottom time. Also in July, Phoenix announced it purchased a Bluefin-21 AUV from Bluefin Robotics Corp. (Quincy, Massachusetts). The AUV can operate in depths up to 1,500 meters, which will be extended to 4,500 meters in late 2012. Massachusetts Firms to Provide Sensors to OOI Nortek USA (Boston, Massachusetts) and Nobska Devel- opment Inc. (Woods Hole, Massachusetts) will supply 3D sin- gle-point current meter instruments (VEL3D) to the Ocean Observatories Initiative (OOI). Under a $327,798 contract, Nortek will provide up to 18 Vector acoustic Doppler velocimeters and under a $117,354 contract, Nobska will provide up to nine MAVS4 current meter instruments. The OOI said it expects to start submitting orders for these instruments this year. Austal Increases Capacity With 3 New Buildings Austal USA (Mobile, Alabama) in July opened three new buildings at its U.S. headquarters, marking the beginning of full assembly-line production for the Independence-variant littoral combat ships (LCS) and joint high-speed vessels (JHSV), which the U.S. Navy has contracted Austal to build. The buildings include the Module Manufacturing Facility (MMF) Phase 2, Assembly Bay 5 and an office complex. With 68,750 square meters of manufacturing space, the MMF is capable of constructing six aluminum vessels per year. Assembly Bay 5, measuring 130 meters by 41 meters, is long enough to construct LCS completely inside. Fugro Begins Survey of 1st US Offshore Wind Farm Fugro Atlantic (Norfolk, Virginia) has commenced the first phase of a four-part geotechnical and geophysical survey for the U.S.'s first offshore wind farm, Cape Wind, located off Massachusetts, the company announced in July. The program will involve up to 50 scientists, engineers, archeologists and geologists using specialized vessels. SNK Places Order for Second ISE ROV International Submarine Engineering Ltd. (Port Coquitlam, Canada), or ISE, received in July an order for another HYSUB 54 st / AUGUST 2012 www.sea-technology.com
