In the accident where a sightseeing boat sank off the Shiretoko Peninsula in Hokkaido, the hull carried by a work boat while being suspended in the sea fell to the seabed at a depth of 180 meters off the coast of Shari-cho, Hokkaido on the morning of the 24th.
It was discovered that the front railing of the hull, which had been threaded through a nylon string for lifting, had come off, and the salvage company is now adjusting to see if the hull can be lifted again by remote control using an underwater camera.
In the accident where the sightseeing ship "KAZU 1" sank off the coast of the Shiretoko Peninsula, the hull was lifted from the seabed at a depth of about 120 meters on the 23rd, and was suspended in the sea about 20 meters below the sea surface. It was being carried, but on the morning of the 24th, it fell about 11 kilometers west of Utoro Port in Shari Town.
A salvage company was inspecting the condition of the hull in the sea while the workboat was in operation, but found that the hull had fallen between 8 am and 10 am, and then sank to the seabed at a depth of 182 meters. It was confirmed that it was.
According to people familiar with the matter, a salvage company examined it with an underwater camera and found that the railing in front of the hull, which had been threaded through a nylon string for lifting, had come off.
It is possible that the railing came off and the hull fell out of balance in the tide, and some of the strings were broken.
Also, according to the Japan Coast Guard, the hull is sunk with the bottom down and remains in its original shape as long as it is confirmed by an underwater camera.
The salvage company is adjusting the hull by remote control using an underwater camera to see if it can be lifted again, and if it is technically possible, it will start full-scale preparations on the 25th, at the earliest. The policy is to lift it again on the 26th.
Expert "Did the resistance of the tide affect?"
Hiroyasu Ito, who was the top maritime security officer and chief of the security and rescue department at the Japan Coast Guard, said that the tour boat had fallen. It is probable that the hull was affected by resistance and the rope that was being reinforced was loosened. "
On top of that, regarding the impact on the investigation and investigation, "Since the seabed is 180 meters deep, there is a possibility that it may be damaged to some extent. However, when the hull is first discovered, the surroundings of the ship are photographed and evidenced. It should be holding down, and it is possible to distinguish whether it is a scratch that was made this time or not. "
Regarding the work for future withdrawal, "This time there is no need to check the inside of the ship, so there is a possibility of working with an underwater camera. There is no influence on the depth, but the biggest problem is the tide. I think it's difficult to control while reading the tide, but if all goes well, I think we can do the salvage work in a few days. "
The fisherman who searched for "I'm worried if the hull is damaged"
Akihiko Kosaka (63), a fisherman in Utoro, Shari-cho, who searched for the missing person with his friends after the accident, said that the hull of the sightseeing boat "KAZU 1" had fallen to the seabed off the coast of Shari-cho. I was expecting it, so I'm sorry, and I'm worried that the hull may have been damaged by the fall. "
Chief Cabinet Secretary Matsuno "I will try to give a polite explanation to my family."
Chief Cabinet Secretary Matsuno said at a press conference in the afternoon, "No noticeable damage was found at this time, and in the future, the business operator will conduct an investigation with an underwater camera, etc. for repatriation, and also investigate the cause of this situation. At this point, we are not at the stage where we can say the schedule for future withdrawal, but we would like to make an effort to give a polite explanation to the family from the Ministry of Land, Infrastructure, Transport and Tourism.
