Berliner Boersenzeitung - What happens when the Strait of Hormuz re-opens?

AFP examines how the re-opening could work and why a return to normal is likely to take time.

- Are ships ready? -

Once formal approval is given to re-open, stranded ships could theoretically begin to move through the strait almost immediately.

Crews that have been idle for months will most likely have "performed regular onboard drills and maintained the ships' machinery, technical installations and equipment", Jakob Larsen, head of security at shipowners' association Bimco, told AFP.

However, some ships may require underwater hull cleaning to remove barnacles and other marine growth accumulated during the shutdown.

The strait, through which roughly 20 percent of the world's crude oil supply normally transits, was effectively closed by Iran after it came under fire from the United States and Israel.

About 500 ships and 20,000 seafarers have been stranded in Gulf waters, according to the International Chamber of Shipping, a maritime industry group.

- Who can pass? -

Operators are expected to proceed cautiously and insurers may even require naval escorts, according to Hugo Rousse of maritime tracking group AXSMarine.

The first to cross the strait could be "shipowners who operate their own fleet" and those "not listed on a stock exchange", he told AFP.

"Given the elevated earnings still prevalent in the tanker sector, higher war risk insurance is unlikely to be an obstacle," said Tim Smith, director at MSI, a maritime industry analysis firm.

Tankers linked to Kuwait, Iraq, the United Arab Emirates and Saudi Arabia are likely to be among the first to resume transits, said Arne Lohmann Rasmussen, an analyst at Global Risk Management.

- Must mines be cleared first? -

Iran has designated the central area of the strait as a mine-danger zone.

Until mines are cleared, "ships can use the coastal traffic zones which are mine-free but which are not well-suited to accommodate normal volumes of maritime traffic", Larsen said.

France and Britain have been working since March to assemble a coalition to remove mines and help restore shipping flows.

The United States has also requested "the deployment of mine-clearing capabilities", a European source said Tuesday, adding that French and German vessels had been mobilised for that purpose.

- How long before a return to normal? -

Re-opening the waterway will only be a first step.

Crew changes are needed, disrupted supply chains restarted and strategic energy reserves replenished.

Some tankers could take more than one month to reach Europe after the route reopens, according to Argus Media analysts.

They estimated that it could take four to six months before crude export volumes return to their prewar levels.

"Not everything will go back to normal with the snap of a finger," Rousse said.

He said some buyers have found alternative suppliers, including the US and Nigeria, and have established new shipping routes and commercial contracts.

- Will ships have to pay? -

US Vice President JD Vance told CNBC on Monday there was an understanding with Iran that the strait would re-open "in a toll-free way for the long term".

Iran's foreign ministry, however, said the deal would allow it to charge maritime service fees rather than imposing "tolls".

Such fees would put shipping companies in a bind, however, as it could mean transferring funds indirectly to Iran's Revolutionary Guard, which several countries consider a terrorist organisation.
