Those of you that served in the US Navy (especially the Pacific Fleet) -- do they send all the ships out that were in port at Pearl Harbor? I know that many private ship owners have left port (in their boats) due to the warnings.
I don't know much about the ability of large navy ships to handle tsunami's in open water.
I don't know much about the ability of large navy ships to handle tsunami's in open water.
So, that’s an interesting question. I have attached an article discussing a tsunami and air craft carriers specifically ( the article is rather vague ) I am anxious to see what the Navy did with this situation. I imagine, after a quick assessment they put into play their practiced plan for such an event. ( every imaginable scenario in the Navy gets reviewed and practiced )
My experience is every naval vessel at port that is capable of getting underway during a catastrophic event is sent out to sea. While in port, every naval ship and submarine that has an operational propulsion system is staffed at all times with a crew able to get the ship underway in a short period of time. Tenders are always available around the clock for assistance as well. I doubt they send ships out that only have back up generator capability.
I experienced two such events with hurricanes in Norfolk at Naval Operating Base. On both occasions, even though the crew was a “skeleton crew” the Ike ( CVN69 ) was able to get underway in short order, and ride out the storm. ( Short order in this instance was a couple of hours )
The purpose to move as many ships as possible out to sea is to minimize the damage to the port infrastructure as well as not end up with ships where they do not belong. Massive waves moving stationary ships tied up to piers is a recipe for disaster.
I have witnessed an Air Craft carrier specifically and a Fast Frigate manage 30 plus foot waves in the open ocean. How that translates to facing a long series of tsunami waves ( let’s say 10 feet or higher ) I do not know. It takes a series of waves about 8 feet high to get a carrier moving up and down when it is moving forward during flight ops into the waves so obviously, for smaller ships, a couple of feet seems about right. I believe most vessels now have communications equipment to determine best position to survive a series of a tsunami waves, along with being able to track a tsunami wave for up to the minute information.
Every naval pier has a large amount of electrical supply, fresh water, sewage systems, etc. etc. as part of the structure since a ship can be tied up for a long period of time. There is also floating platforms around the ship, multiple floating platforms for divers and welders to conduct whatever maintenance underwater is happening when a ship is in port. These platforms are heavy and also have electrical, pneumatic, hydraulic systems and cables attached.
Many piers can have Cranes on them to temporarily assist with maintenance evolutions as well as resupply before or after a ship ports. All of this stuff can cause massive damage if it comes in contact with a massive series of waves and wind.
Short answer is I believe they would have had a pull forward operation underway of the initial assessment indicated there was any chance of significant waves and a tidal rise ( if the water comes up several feet all at once as happens in a Tsunami ) they most likely would have as many ships get out of Port as possible.
They certainly have an operational plan for these scenarios that is periodically updated as well as practiced to ensure the best case result.

I read that cruise ships in Hawaii left port, and passengers that did not make it back on board were told to "seek higher ground" (think this came from a tweet shown on NYT tsunami tracking page)
Watching Ozzy funeral on sky news and reports indicate the tsunami warning for Hawaii has been lifted and evacuation orders have stopped as tsunami now no longer expected to hit Hawaii. Russia, Japan and other countries also downgrade tsunami warning.
Hawaiians cram roads away from coasts as tsunami waves arrive
Following early warnings to evacuate coastal areas, thousands of Hawaiians head for higher ground - for many it isn't the first time.
