Nothing official yet; but, my guess is that Stockton was overcrowded and may have advised Ocean Life to wait at a safer anchorage until the Port of Stockton has sufficient maneuverable room to handle more bulk cargo ships.

Certainly odd as she was anchored off Hunters Point LA 31/8-5/9 and has now returned to that anchorage. Suspect not a problem with the ship though, as she doesn't seem to have required tug assistance for the return passage (probably just for the turn in the river).

You are the man on the ground there, Oldkayaker. Why don't you simply phone the local port authority and ask them what is going on. The worst they can do is tell you to mind your own business!

May be a story here since these transits are normally routine and, during the past five years of my experience, bulk cargo ships heading for upriver ports do not normally stop and rest mid-river at this end of the Carquinez Strait... sorry Mumbles but there is something unusual about this.

Anchored, waiting, with the tugs keeping her from swinging across the channel. Possibly waiting for the bridge (if it has a fault) or for the berth to free up. I suspect no great story.

May be a story here.
Early this morning around 10AM I noticed on Marine Traffic that bulk cargo ship, Ocean Life, was transiting Carquinez Strait on what appeared to be a routine transit in route to Stockton.

However later, during my routine bicycle ride to the Benicia-Martinez Bridge, I noticed that Ocean Life was apparently waiting in the center of the Sacramento River near the eastern end of the Carquinez Strait with the assistance of tugs, Delta Audrey, and another tug, out of sight on its starboard side, and not proceeding to pass under the bridges as it would normally do when going to Stockton.

The Benicia-Martinez Railroad Drawbridge was also not in its normal up position needed for a ship to pass safely beneath.

A later check with Marine Traffic AIS at 3:00PM shows Ocean Life in it's same position as the above photo shows it to be earlier this morning.
