The 2009 USS ''Port Royal'' grounding was a ship grounding by the United States Navy guided missile cruiser ''Port Royal'' off Oahu, Hawaii on 5 February 2009. In the incident, the ship ran aground on a coral reef, damaging and necessitating repairs to both the ship and the reef. The incident received wide press coverage in Hawaii, at least in part because of the damage caused to a sensitive coral environment. A United States Navy investigation found that the grounding was caused by a combination of a misread navigation system, a sleep-deprived commanding officer, broken equipment, and an inexperienced and dysfunctional bridge team. The ship's commanding officer, Captain John Carroll, was relieved of duty and disciplined. Three other officers and one enlisted sailor were also disciplined. The United States Navy reattached 5,400 coral colonies in an attempt to repair damage to the reef. ==Grounding== After spending time in the Pearl Harbor shipyard for $18 million in scheduled repairs, ''Port Royal'' departed for the open ocean off Oahu for sea trials at 08:15 on 5 February 2009. The ship's fathometer was broken. At 12:01, the Voyage Management System's (VMS — an automated navigation system) primary input at the chart table was shifted from a forward Global Positioning System to forward Ring Laser Gyro Navigation, an inertial navigator. Three times the VMS dead-reckoned the ship's location, mistakenly reporting the ship's location as from its actual position. The error was not noticed by watchstanders. The ship was undergoing her first sea trials, including full power, steering and helicopter flight operation checks.〔Cole, William, ("Navy Ship Grounding Detailed" ), ''Honolulu Advertiser'', 12 July 2009.〕 The grounding occurred at 8 p.m. on 5 February 2009 when ''Port Royal'' ran aground about a half-mile south of the Honolulu International Airport's Reef Runway. No one was injured in the incident and no fuel was spilled. The location of the grounding was in full view of aircraft landing and departing from the nearby airport, causing embarrassment to the Navy.〔McAvoy, Audrey, "(Navy punishes former Port Royal CO )", ''Military Times'', 5 June 2009.〕〔Cole, William, "(Hawaii-based ship's grounding detailed )", ''Honolulu Advertiser'', 7 July 2009.〕 The cruiser, which has a draft of , ran hard aground on a sand and rock ledge in an estimated 14 to 22 feet (5–7 m) of water. The salvage ship made three unsuccessful efforts to pull ''Port Royal'' off the sandbar (Friday, Saturday and Sunday, 6–8 February), despite full-moon high tides and the offloading of 200 tons of fuel and water, 7,000 gallons of raw sewage, and 15 tons of crew members.〔〔Kakesako, Gregg, "Navy Cruiser Dumps 5,000 Gallons Of Slop", ''Honolulu Star-Bulletin'', 11 February 2009.〕〔Kakesako, Gregg K., "Extensive Coral Reef Damage Revealed In Ship's Grounding", ''Honolulu Star-Bulletin'', 20 February 2009.〕 According to the U.S. Pacific Fleet, the ship ran aground while moving very slowly as she transferred shore-based aviation assessment officials to a smaller boat to take them to shore. An oil recovery ship, ''Clean Islands'' was behind the ship to clean up oil spills. Rear Admiral Dixon R. Smith, the commander of the Navy Region Hawaii and the Naval Surface Group Middle Pacific, embarked the ship on the morning of 6 February to serve as the on-scene commander.〔〔Associated Press, "Navy Warship Runs Aground Near Honolulu Airport", ''Miami Herald'', 7 February 2009.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2009 USS Port Royal grounding」の詳細全文を読む スポンサード リンク
