New Piracy Warning:
            Warning Ships in passage in West Africa, South America, Central America and the Caribbean waters regarding Piracy and Armed Robbery. In Nigeria, mainly in Lagos and Bonny River heavily armed pirates are targeting ships while underway along the coast and river at anchorages and ports. In some cases, crew members were kidnapped. Pirates are violent and in recent incidents some crew members were injured. Ships are advised to take extra precautions and avoid anchoring if possible. Direct berthing is safer. Generally, all waters in Nigeria are risky. Attacks are increasing off Cotonou, Benin. Pirates are violent and some crew members were injured during recent attacks. Pirates are armed and have fired at ships. A number of vessels were reported hijacked for a few days and had their ships properties and cargo stolen. Ships are advised to take additional precautions and maintain strict anti piracy watches and report all piratical attacks and suspicious movements of craft to the IMB Piracy reporting Centre, Kula Lumpur, Malaysia. The centre can be contacted 24 hours, everyday on the anti-piracy helpline: Tel: +603 2031 0014, Fax: +603 2078 5769 Telex: MA 34199 IMBPCI, Email: IMBKL@ICC-CCS-.ORG or Piracy@ICC-CCS.ORG IMB Maritime Security.

Regulated Navigation off Portsmouth, NH:
            The purpose of this special notice is to advise the public that the Coast Guard has established a Regulated Navigation Area from August 5, 2011 through September 15, 2009. The navigation area covers approximately a one mile stretch of the channel between Henderson Point Light on Seavey Island (43-04-29.319N, 070-44-10.189W) to Badgers Island Buoy 14 (43-04-51.951N, 070-45-21.518W). The purpose of this temporary final rule is to restrict the speed of vessels transiting in the area while diving and loading operations take place at the Portsmouth Naval Shipyard. These speed restrictions will be enforced to reduce the wake of passing vessels which have the potential to endanger divers' lives. All vessels transiting through this area shall proceed with caution, operating at no more than 5 knots and in a manner so as to produce no wake when the navigation area is being enforced. Notice of the speed restrictions will be broadcast on VHF-CH 16 one hour prior to commencing and every half hour until cancelled. Documents relating to this Temporary Final Rule will also be available in the Federal Register by going to http://www.regulations.gov , inserting USCG-2011-0708 in the “Keyword” box, and then clicking “Search.” They are also available for inspection or copying at the Docket Management Facility (M-30), U.S. Department of Transportation, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. FOR FURTHER INFORMATION CONTACT: If you have questions on this temporary rule, call or e-mail Lieutenant Junior Grade Terence Leahy, Waterways Management Division at Coast Guard Sector Northern New England, telephone 207-767-0398, e-mail Terence.O.Leahy@uscg.mil . If you have questions on viewing the docket, call Renee V. Wright, Program Manager, Docket Operations, telephone 202-366-9826. (First District LNM 31)

Passaic River, NJ, Construction Update:
            Construction of a steel enclosure and removal of sediment will be done in the lower Passaic River from August 2011 to November 2012. Hours of operation are Mon-Sat from 0700-1700. Equipment will be in position 24/7. One Crane Barge, One Tug Boat and scow barges will be on scene. From on, or about, August 1-9 a layer of grit will be installed along the seawall and outside of the Federal Channel. A sheet pile enclosure will then be constructed along the seawall, and outside of the Federal Channel, at the Diamond Alkili Superfund site, approximately 1,100 yards west of the NJ Turnpike bridge at mile 2.7. This work will last from approximately Aug 13, 2011 to Jan 31, 2012. One dredge barge will remain within the enclosure to remove sediment. Concrete mattresses will be installed around the enclosure for scour protection prior to Dec 1, 2011. A 12 inch diameter pipeline, approximately 1,300 feet long, will be installed parallel to the shoreline and outside of the channel, for pumping sediment. It will be mounted on 16 inch diameter piles every 250 feet. It will be about 135 feet from shore and lighted. Sediment removal and backfilling is due to run from March to Aug, 2012. The steel enclosure will be removed between Sep-Nov 2012. During this project work vessels and lighted anchor buoys will extend into the Federal Channel reducing the channel width to between 143 feet to 278 feet. The vessels and buoys may be moved with 72 hours notice by contacting the Weeks Marine tug on VHF CH 65 or Mr. Claude Dion at 908.230.5279. (First District LNM 28)

Atlantic City NJICW Drawbridge to Close for Four Months:
            Mariners are advised that the Coast Guard has issued a temporary deviation from the drawbridge operating regulations for the Route 30/Absecon Boulevard Bridge, at NJICW mile 67.2, across Beach Thorofare in Atlantic City NJ. Under this deviation, the drawbridge will be closed to vessels requiring an opening beginning at 7 a.m. on Friday, September 16, 2011 through 11:59 p.m. on Friday, January 13, 2012.  This closure is necessary to facilitate extensive rehabilitation and to maintain the bridge’s operational integrity. The available vertical clearance in the closed position to vessels is approximately 20 feet, above mean high water.  The navigable channel will not be obstructed so vessels that can pass under the bridge without a bridge opening may continue to do so at anytime.  The Atlantic Ocean is an alternate route for vessels with mast heights greater than 20 feet and the drawbridge will be unable to open in the event of an emergency.  At all other times, the bridge will operate in accordance with drawbridge operating regulations set out in Title 33 Code of Federal Regulations Part 117.733(e).  Mariners able to pass under the closed span may do so, adjust their transit accordingly and use caution when transiting the area. (5th  District Bridge Branch)

The work consists of installing cofferdams around all ten piers that are in the river. Any scaffolding and work platforms will be contained inside the cofferdams. Crane barges and support barges will be placed around the cofferdams. The work schedule will be Monday through Saturday from 6 a.m. to 6 p.m., except when a concrete seal pour is being made. That work will be performed on Fridays at 6 a.m. and will run continuously until completed, up to 36 hours. The date of these pours has not yet been determined.
