In the accident where a tourist boat sank off the Shiretoko Peninsula in Hokkaido, the Japan Coast Guard contracted with a private company and used a method called "saturation diving" that allows diving into deeper seas at a depth of about 120 meters. I am going to search the ship.
The tourist ship "KAZU 1" (19 tons) that sank off the coast of the Shiretoko Peninsula was found on the seabed at a depth of about 120 meters, and the Japan Coast Guard and the Maritime Self-Defense Force are continuing to search for people left behind on board. However, the tide is fast and the visibility is poor, making it difficult.
For this reason, the Japan Coast Guard decided to conduct a search on the seabed by a method called "saturation diving" that allows diving into deeper seas, and contracted with a private company with special technology for 877 million yen. , I'm planning to start searching as early as this month.
While the Japan Coast Guard diver can dive at a depth of about 60 meters, saturated diving is a method of diving while acclimatizing the diver's body to the high water pressure of the deep sea, and is underwater at a depth of more than 100 meters. It is said that it will be possible to work in.
The Ministry of Land, Infrastructure, Transport and Tourism will proceed with the search on the seabed, while also considering how to raise the hull.
According to the 1st Regional Coast Guard Headquarters, etc., heading to the site sea area is the "New Japan Maru" owned by a company outsourced by the "Nippon Salvage" contracted by the Japan Coast Guard, on the evening of the 2nd. I left the port of Kagoshima prefecture.
We will arrive at the site sea area as early as early this month and use a remotely operated unmanned submersible to investigate the inside and surroundings of the sunken ship and search for missing persons.
Judgment of the captain The influence of the president's instructions and authority on the operation is also investigated
On the other hand, in this accident, the Japan Coast Guard searched the office of the tourist boat operator "Shiretoko Tour Boat" in Shari-cho, Hokkaido on the 2nd on suspicion of accidental fatalities.
Normally, when investigating a ship accident, the captain, seafarers, and other parties are examined for negligence by investigating the situation of maneuvering, but according to the people concerned, there is a suspicion of negligence when taking a search warrant. The target is that in addition to Captain Noriyuki Toyoda of "KAZU 1", President Seiichi Katsura of the company is included.
According to the investigation by the Japan Coast Guard so far, President Katsura and Captain Toyota decided to set sail while recognizing that the weather may be rough on the day of the accident, and then return if the sea is rough. It is known that the agreement was made, and the Japan Coast Guard is planning to investigate whether there was any problem in the judgment.
Then, in addition to the judgment by the captain, we will investigate in detail how much the president's instructions and authority affected the operation on the day.
