The Fassmer shipyard in Germany is currently cinstructing a new research vessel to be owned by Bundesamt für Seeschifffahrt und Hydrographie (BSH), the Federal Maritime and Hydrographic Agency. The new 75-meter-long ship, the Atair, will replace her 30 year old namesake, and will be the first German research vessel operating on liquefied natural gas (LNG) fuel. The engines for the new vessel will be supplied by Wärtsilä, who will also supply exhaust cleaning systems based on selective catalytic reduction (SCR) technology and the LNGPac system for complete fuel gas handling.

The video documentation of the cargo ship El Faro and the associated debris field has been completed but the vessel’s voyage data recorder was not located, according to the National Transportation Safety Board. “Over the years we’ve completed many investigations without the aid of recorders and other investigative tools,” said NTSB Chairman Christopher A. Hart. The 790-ft. ship went missing on Oct. 1 during Hurricane Joaquin and was located on Oct. 31 in about 15,000 feet of water in the vicinity of its last known position near Crooked Island, Bahamas.

A U.S. Navy salvage team prepared on Sunday to launch a remotely operated submersible to confirm that wreckage discovered near the Bahamas was that of the cargo ship El Faro, lost in a hurricane last month along with its 33 crew members. The team's mission is to document the shipwreck and any debris field, and to retrieve the sunken vessel's voyage data recorder - similar to an airplane's black box - as part of an investigation into its loss, according to the National Transportation Safety Board (NTSB).

The safety zone and traffic restrictions in place from markers 936 to 938 on the Mississippi River following a towboat collision and subsequent oil spill have been lifted, according to the U.S. Coast Guard. A section of the lower Mississippi River was closed to all traffic except response vessels last week after two towboats collided Wednesday at Mississippi River mile marker 937, rupturing the cargo tank of a barge carrying slurry oil which discharged approximately 150,000 gallons of oil into the river.

An Examination of USCG Sonar Expansion

A civilian contractor steadies a M18 Mod 2 Kingfish Unmanned Underwater Vehicle (UUV) as it is lifted with a crane onto the deck of an 11-meter rigid-hull inflatable boat. The Kingfish uses side scan sonar to search and discover objects of interest. This marks the first time these UUVs have been added to mine countermeasure operations in the U.S. 5th Fleet area of responsibility.

The U.S. Coast Guard is planning to widely use sonar to support its maritime security and marine environmental protection missions. The agency currently has limited capability to detect objects below the water’s surface and relies on others (such as the U.S. Navy or the commercial sector) when such detection is needed. Sonar is an acronym for Sound Navigation and Ranging. The principle is similar to radar, used in the atmosphere. While radar uses radio waves, sonar relies on sound waves, which propagate much better than radio waves do in water.
