Ammunition Dock Project Updates – The Log


In December 2019, the Navy began construction of a project to construct a replacement ammunition jetty, associated waterfront facilities, causeway and a public navigation channel within the bay. from Anaheim. The project is expected to last at least five years.

SEAL BEACH— On November 30, the Naval Weapons Station at Seal Beach announced a pile driving campaign scheduled to begin December 1 as part of the Navy’s project to replace the ammunition pier at the Seal Beach Naval Weapons Station. .

More than 900 concrete piles will be driven into positions that will support the new pier structure in the center of the bay throughout the campaign. Work is to take place during the week, daylight hours only, although this schedule may occasionally change based on weather, equipment availability and other variables.

Although it was initially assumed that the pile driving would take up to a year, the results of a pile driving test campaign in September indicated that most of the work could be completed by the start of the construction period. summer 2022.

“The project is being built in phases with several parts already completed,” said Gregg Smith, public affairs manager for Seal Beach Naval Weapons Base, in a Dec. 13 email. “A new civil navigation channel was opened to the public in January of this year, and a causeway was constructed at the site of the old navigation channel. These improvements have significantly improved safety and security by removing Public boaters much further away from the Navy’s ammunition loading operations. The new shipping channel still has some final stages needed, including the placement of additional rip-rap and permanent aids to navigation. carried out a major coastal dredging effort to enlarge the bay’s vessel turning basin.

Here is the current project schedule:

  • Mobilize: planned for December 2019; Completed
  • Stone removal: scheduled from December 2019 to summer 2020; Completed.
  • Creation of the roadway: planned winter 2020-summer 2022; In progress.
  • North Mole Partial Removal: planned from Spring 2020 to Fall 2020; Completed.
  • New civilian boat channel: planned from spring 2020 to winter 2021; Completed.
  • Dredging of the interior of the port: planned from spring 2020 to autumn 2021; Completed.
  • New truck rollover construction: scheduled from spring 2021 to summer 2022; In progress.
  • Construction of a new jetty: planned for fall 2021 – end of 2024; In progress.
  • Construction of a new interior breakwater: fall 2021 – summer 2022; Foreseen.

“Currently, we are working on the construction of the new ammunition pier and truck rollover area in the center of the bay,” Smith said. “Once the project is completed by the end of 2024 and the new jetty is operational, we can simultaneously load two medium-sized ships such as destroyers, or a much larger ship such as a multipurpose amphibious assault ship. “

An updated aerial video of the project’s construction is available on the Navy’s website. The video is updated quarterly. All images are simulated and intended to show general progress only. Areas for depositing equipment, temporarily storing rock or soil, and creating dunes are not indicated. The last slide of the video features an aerial view of the project when completed.

Anaheim Bay is a large, wet harbor complex at Seal Beach. The US Navy kicked off the first phase of a $ 154 million construction project in 2020 to reconfigure Anaheim Bay and replace a WWII ammunition pier at Naval Weapons Station Seal Beach. The plans outlined for the pier and causeway will accommodate 844-foot-long amphibious assault ships or serve two guided missile destroyers for the first time.

“The station’s ammunition loading dock was originally built in 1944 and rebuilt in 1953,” Smith said. “This existing wharf is over 65 years old, has exceeded its design life and was built before the introduction of modern earthquake codes. The condition and configuration of the existing wharf and turning basin limits the size and number of vessels that can be loaded and unloaded with ammunition at the same time. The waterfront configuration also presented safety and security concerns due to the proximity of Navy ammunition operations to civilian small boat traffic crossing the bay to and from Huntington Harbor.

The next closest naval weapons station is on the Kitsap Peninsula, Washington, over 1,000 miles from the US Pacific Fleet hub in San Diego. The new ammunition dock will increase the strategic relevance of Seal Beach to the Navy.

According to an article in Los Angeles Times, “The reconfiguration of Anaheim Bay is a gargantuan undertaking. Navy officials expect contractor Manson / Connolly Seal Beach JV to move or dredge 870,000 tonnes of rock and 1.15 million cubic meters of sand before phase two is completed in 2024. Approximately 370 contract workers will be employed between the two phases of the project, ”Smith said in the article.
