Updates on the McMurdo Barge Pier

McMurdo barge pier launch The barge pier Discovery was launched on 25 October by Gunderson
Marine in Portland, OR. Above, a clip from the launch video.

The launch was witnessed by a large crowd...and was documented in this video by Gunderson Marine.

So what's next? [updated 6 November 2025] First, I suspect there will be some fitting out and punch list items to be attended to. Then...as transportation to McMurdo is part of Gunderson's contract, in January it will be towed to McMurdo by a tug from Trade Winds Towing. Perhaps by Rachel, which was parked next to Gunderson Marine. An ice pier was constructed at McMurdo this past winter, but it developed a crack, so NSF has opted to bring down the mobile causeway system again. The ice pier will need to be dynamited and towed out of the way before the mobile causeway can be deployed. The new barge pier wlll be deployed after ship offload. Meanwhile, work is being done on the mooring system, as some of the bollards (anchor pile caps depicted below) have shifted due to permafrost melt.

October update! Per the revised video link below, the barge pier was scheduled to be launched on Saturday 25 October at the Portland, OR shipyard...open to the public! As for deployment...that is still scheduled for February 2026, after sealift. I don't know whether the sealift or a separate vessel will bring it down, but its installation will take some time, so that won't happen until after ship offload.

...at Port Hueneme, in early June, Seabees of NMCB-3 practiced          assembling and launching a Mabey     Johnson Bridge...something they'll be doing as part of the barge pier             installation this summer. This photo    from a NMCB-3 Facebook page post.

And, this earlier photo was released by NSF/USAP on their "future USAP" section in early May 2025 on this archived web page.. Despite some earlier statements relating to NSF funding cuts, it still appears to be scheduled for delivery to McM in the 2025-26 austral summer season (but not to be ready for use until the following summer). As with the prep work done during the 2024-25 summer, installation will involve the Seabees and Antarctica New Zealand as well as the USAP support contractor.

Below...a significant part of the project at McMurdo last summer...preparing to drill holes for piles that will moor the barge pier.

On 15 May 2025 DVIDS issued a press release about the McMurdo barge pier work done by a detachment of Seabees from NMCB)\-3 based in Port Hueneme, CA. The photos immediately attached to this report show the Seabees doing snow clearance at Williams Field. The drilling equipment was procured and the work was monitored by Antarctica New Zealand...some of the work was done by a Navy Seabee detachment from NMCB-3 (more info and photos about the Seabee deployment to Antarctica)--they also spent time working at Pole.

the planned pier bargeA plan view of the barge pier. Instead of the mooring depicted at left, the pier will be anchored by 4 struts anchored on shore...the piles for which were being drilled by the Seabees as seen in the above photos, with each concrete mooring point anchored by 4 piles. I'm thinking 12 piles...the two struts midships on the barge pier will be anchored to the same mooring point. (more info and barge pier drawings).

But later I learned that some of the piles needed to be redone because they'd "tilted." Could not figure out how that might have happened, but in October 2025 the team returned with the Liebherr LR1160 that Antarctica New Zealand (ANZ) had brought down the previous season and was used to place the piles, here's a great YouTube video featuring the pile extraction. No ice/water in the piles...early in the video they describe having to melt them out to make extraction possible.
