On the 10th, it was found that there was a shallow water about 7 meters deep around the route of the Maritime Self-Defense Force escort ship, which was unable to navigate on its own due to a screw failure in the Seto Inland Sea off the coast of Yamaguchi Prefecture.


The Japan Maritime Self-Defense Force (JMSDF) is investigating the detailed cause, assuming that it may have deviated from its normal course and hit rocks in shallow water.

After noon on the 10th, the Maritime Self-Defense Force's escort ship "Inazuma" was sailing in the Seto Inland Sea off the coast of Suo-Oshima in Yamaguchi Prefecture, when the propeller broke down and it became unable to navigate on its own.



According to the Maritime Self-Defense Force, after undergoing regular inspections at a shipyard in Hiroshima Prefecture, a test run was conducted in the Seto Inland Sea, and there was a shallow water depth of about 7 meters around the route off Suo Oshima. .



"Inazuma" has a "draft" that indicates the length from the sea surface to the bottom of the ship, which is about 11 meters at the deepest part, and both of the two screws have stopped working properly.



The Maritime Self-Defense Force believes that the screw may have deviated from the normal route and contacted rocks in shallow water, and will set up an accident investigation committee to investigate the cause in detail.



In addition, after the survey by the Japan Coast Guard is completed, we will move the "Inazuma" that remains anchored at the site by towing it.

According to the Maritime Self-Defense Force, the escort ship "Inazuma" was conducting a test operation in the Seto Inland Sea after a regular inspection on the 10th, and when the screw broke down, it was conducting an engine-related test.



According to the private website "Marine Traffic," which publishes ship location information, "Inazuma" reversed off the coast of Heigun Island in Yamaguchi Prefecture, and was at a speed of about 55 kilometers per hour for about 20 minutes just before the propeller broke down. It is recorded that it was sailing before and after.



According to the Maritime Self-Defense Force's website, Inazuma's speed was about 55 kilometers, and she may have been sailing at almost maximum speed at that time.
