The saudis built a pipeline across their nation, and are exporting over 5million barrels (a large increase).
There is a great bit of coverage on this by "what's going on with shipping" here: https://youtu.be/r0EvQgLcjMw?t=172
It does not look like this data is part of the paper above.
Fair catch, the data predates the reroute. Although this pipeline is routed to Bab-el-Mandeb which is in the network
Exporting oil from the west side of Saudi Arabia works until some armed group like the Houthis with drones/missiles places a credible enough threat at another chokepoint that the ships won't go.
The choices are then to find a way to get the Houthis to chill out, or use enough military force to cut off the Iranian support for the houthis, or use military force to be confident you have destroyed the houthis' ship attacking capability.
