The National Park Service said Battleship Row tours in Pearl Harbor will be suspended Friday to allow Navy divers to assess damage to an aging shoreside dock at the USS Arizona Memorial visitor center.

Repair work will “likely” cause a one- to five-day day suspension of boat tours again in April, officials said today in a release.

That’s in addition to the ongoing closure of the memorial itself to walk-on visitation since last May due to a problem with its floating dock.

Twin 90-foot floating concrete docks attached to the Arizona Memorial visitor center sank in late September after deteriorated bolt holes between them allowed seawater to flood in.

Navy divers stepped in and patched and refloated the docks. But the sinking may have snapped two 70-foot pilings that anchored one of the docks.

Boat launch operations for tours of Battleship Row were shifted to the remaining usable shoreside dock with minor modifications to the boat launch schedule, officials said.

“The inspection will determine how best to remove and replace the faulty pier,” the park service said in the release.

Between 4,000 and 5,000 people visit the visitor center each day to experience ground zero for the Dec. 7, 1941, surprise Japanese attack on Pearl Harbor.

Visitors continue to see a 25-minute documentary film, followed by transfer to Navy boats for the harbor tour, which transits in close proximity to the Arizona Memorial.

The shoreside dock, put in place in 1999, is scheduled to be replaced. A total of about $4 million is being sought in federal funding and donations to replace the structure.
