rameters at inshore coastal areas, harbors and estuaries. It can be used as a permanent or temporary platform. The High Power Vibrocorer retrieves continuous, undis- turbed core samples from unconsolidated and semiconsoli- dated sediments. It can collect cores 100 millimeters in diameter and up to 9 meters in length in dense or compact sediments. Scanunit Named GUARDIAN BWT Exclusive Sales Agent in Sweden Hyde Marine Inc. (Pittsburgh, Pennsylvania) named in July Scanunit Ab (Helsingborg, Sweden) as the exclusive sales agent in Sweden for Hyde GUARDIAN ballast water treat- ment (BWT) systems. The chemical-free GUARDIAN BWT system uses filtration and ultraviolet disinfection to treat ships' ballast water. The system is International Maritime Organization type approved. Smit Lamnalco Receives Support, Towage Contract Smit Lamnalco (Sharjah, United Arab Emirates) received in June a 10-year, $120 million marine support and towage con- tract covering LNG export terminal operations in Papua New Guinea, led by Exxon Mobil Corp. (Irving, Texas). The project is expected to produce more than 9 trillion cubic feet of gas for export. The contract will provide tugboats and crews to assist berthing and unberthing of LNG carriers. The agreement also specifies deployment of four newbuild RAstar 3200-class, 65- tonne bollard pull azimuth stern drive tugs to provide escort and LNG terminal towage services. ARA Deploys Sonardyne USBL System in Port Survey ARA Inc. (Sykesville, Maryland) has completed a subsur- face survey of Terminal 91 in the Port of Seattle, in which it deployed its ROV ROUMRS and Sonardyne International Ltd.'s (Yateley, England) Scout USBL acoustic positioning sys- tem, Sonardyne said in July. ARA's operation was to identify and clear any magnetic anomalies that could potentially warrant further investiga- tion. The survey was completed in March. ARA mobilized its ROV ROUMRS, which was fitted with a Sonardyne WSM 6 transponder. A Scout transceiver was deployed from the side of the dock on a pole. Positioning data from Scout was fed to Sonardyne ViewPoint navigation software. Proteus Completes Red Sea Satellite-Based Bathymetric Mapping Project in 10 Days Proteus (Abu Dhabi, United Arab Emirates) has completed a 200-square-kilometer bathymetric mapping project along the Red Sea coastline in 10 days, deriving the bathymetric data from DigitalGlobe (Arlington, Virginia) WorldView-2 high-resolution, eight-band satellite imagery. The project could have taken six to eight months if the data had been collected by boat due to required government per- mits and shallow-water navigation obstacles, Proteus said. The satellite bathymetry process extracted seafloor eleva- tion measurements to depths of 20 meters with a 4-meter point density at distances up to 5 kilometers off the Saudi Ara- bian Coast. The bathymetric data supported an environmental assessment by Sogreah (Lyon, France) in preparation for con- struction of a power plant south of Jeddah, Saudi Arabia. www.sea-technology.com AUGUST 2012 / st 59
