This South Korean vessel is among the ships damaged in the Strait of Hormuz
Traversing the Strait of Hormuz remains one of the most dangerous trips a vessel can take.
Despite assistance from the US Navy, ships are still being attacked.
"To transit the Strait of Hormuz you need agreement between the captain and the crew to take the risk. You need war risk insurance. And the captain has to make the final decision," says Steve Cameron, a former merchant navy officer and maritime consultant.
Missiles and drones are a threat from the air, but under the surface mines may also be lurking.
