Shiretoko Sightseeing Ship Sinks A hole in the wall of the hold The structure makes it easy for water to collect in front

According to an interview with the people concerned, a hole was made in the wall separating the two warehouses under the deck in front of the ship in the accident where the tour boat sank off the Shiretoko Peninsula in Hokkaido, creating a large space. I did.

The structure is such that water tends to collect in front of the bottom of the ship, and the Japan Coast Guard is investigating in detail the relationship with this accident, which seems to have been flooded from the bow side.

In the accident where the tour boat "KAZU 1" sank off the coast of the Shiretoko Peninsula, killing 14 people and missing 12 people, on-site inspections of the ship lifted from the seabed are underway, and the hull is on the 1st. , Was landed.

Under the deck in front of this ship, there are two warehouses = holds, and as a result of detailed investigation by the Japan Coast Guard, it was found by interviewing the people concerned that there was a hole in the wall separating the two holds. I did.

It seems that it was not a hole made by impact etc. but an artificial one, and due to this hole, nearly 40% of the entire bottom of the ship is one large space, and more water collects in front of the bottom. It was an easy structure.

According to the investigation so far, it is known that the hatch cover connected to the hold below from the deck in front was removed, and it is believed that the water was flooded from the bow side according to the contents of the report of the tour boat, and the Japan Coast Guard reported this accident. I'm going to investigate the relationship with.

According to the Ministry of Land, Infrastructure, Transport and Tourism, in the ship inspection conducted by the government last year, there are two walls, one is the wall of the engine room where the engine is located from the center to the rear of the bottom of the ship, and the other is the wall of the room near the steering wheel. After confirming that there was a hole in the place, the operating company closed the hole after being pointed out by the inspector.

On the other hand, in the inspection conducted three days before this accident, the fact that it was pointed out that there was a hole in the wall separating the two front tanks could not be confirmed, so the government was aware that the inspector was aware of it. I am going to verify the inspection just before the accident.
