Friday is ambitious. Key signal will be if ships transit with AIS transponders on. Full return to pre-war levels will take months, not days or weeks, due to safety, insurance, crew concerns, and ship repositioning.
Many ships went through 'dark' (lights off) to avoid detection. Ships were subleased by ADNOC, Saudi Aramco, Qatar Energy to other regions. Getting them back takes time. Insurance firms and crews must sign off.
