The Strait of Hormuz is supposed to be 'open' now, based on the MoU framework, though things are expected to be extremely slow moving, despite signs of life in terms of an increased transit flow becoming evident only this week.
The saga of just how hundreds of ships will traverse is developing and tenuous: "The UN's International Maritime Organization says it will begin evacuating more than 11,000 sailors stranded in the Gulf due to the Middle East war," per AFP.
"This large-scale operation will be carried out in close cooperation with Iran, Oman, all other coastal States in the region, the United States and the maritime industry," IMO secretary-general Arsenio Dominguez stated Tuesday.
"We have secured the necessary safety guarantees and have thoroughly verified the conditions for safe navigation to support these operations," he adds.
Presumably this simply means UN assistance in seeing the stranded crew make safe passage with their cargo and on their ships. Reuters explains:
The evacuation process under the IMO plan, which has been under discussion for months, will be phased, Oman's defence ministry said separately in an advisory.
"Given the elevated risk of collision in the current environment, a gradual and controlled evacuation of vessel traffic is required," it said.
The Omani ministry said the so-called Traffic Separation Scheme was "not safe for use at this time" and two temporary routes to north and south of the scheme could be used for evacuation.
"Vessels will be contacted individually and advised of their allocated transit day by the parties coordinated by IMO," the ministry advisory said.
According to a backgrounder in the NY Times:
Today, the stress on the roughly 11,000 stranded sailors in the Persian Gulf may be even greater. Seafarers now have internet access and are often watching livestreams of attacks happening around them, while also seeing explosions from their ship decks.
“The fact that they are sitting on board the ships with real-time information — it is psychologically very traumatic,” said Mr. Khanna, 55.
Three commercial vessels have been hit by U.S. forces this week. One of the strikes killed three people, bringing the number of seafarers killed since the start of the war to 14. All told, there have been 46 attacks on international ships in and around the Strait of Hormuz since Feb. 28, most by Iran and some by the United States.
Scant details have been issued by the International Maritime Organization. There's a backlog of some 500 or 600 vessels, but some are making it through this week.
Notably, lead crew members or captains have all along not abandoned their tens of millions or hundreds of millions in precious commodities/cargo - especially after already enduring the blockade for this long.
