  FollowAvondale shipbuilders have discovered problems with the bolts used to fasten the Anchorage’s engines to the ship, causing delays in the amphibious transport dock’s delivery, the Navy Times newspaper has reported. Similar problems were found aboard the Somerset, another in the LPD 17 San Antonio class ships that was christened last month at the Huntington Ingalls Industries shipyard in Avondale, scheduled to close late next year.

Parked behind the Somerset is the Anchorage, visible behind the yellow crane. At the time, shipbuilders and the Navy were dealing with problematic engine bolts.
  The bolt problem was discovered on the Somerset during an inspection in mid-July, weeks before the July 28 christening at which families of Sept. 11, 2001 victims of the United Flight 93 converged on the Avondale shipyard. Bolts, fabricated at the shipyard’s machine shop and used to fasten the engine frames to the ship, were improperly installed, according to the report.

  That led inspectors to find bad bolts on the Anchorage, which had been scheduled to be delivered to the Navy the week before the Somerset’s christening, according to the Navy Times report.

  The Anchorage was parked just behind the Somerset during the ceremonies last month. The shipyard is scheduled to deliver the Somersetnext year. Delivery describes the transaction in which the Navy takes legal custody of the ship.

  The Anchorage is now scheduled to leave Avondale for its home port of San Diego in October, according to the report.

  “The discrepancies are related to the fitted bolts’ ability to withstand shear forces during a shock event; there are no issues with fatigue loading of normal operation of the systems,” Navy Times quoted a Huntington Ingalls Industries spokeswoman as saying.

  Huntington Ingalls has a larger shipyard in Pascagoula, Miss., which will build the remaining LPD 17 ships under contract. The bolt problem is limited to the Avondale shipyard, according to the Navy Times report.

  The Anchorage underwent acceptance trials in June and reportedly will undergo another trial this month.

  The Navy has found problems with other ships in the LPD 17 class, including welds that were too thin.
