Construction accidents at the former site of Koshiba oil storage facility (third report)

Currently, it is stored in the oil storage tank, which is presumed to have fallen for the rapid resumption of rescue operations.
Fixed work at the top of the remaining tank where there is a danger of collapse in conjunction with drainage work of water (turbulent rainwater, etc. (estimated approximately 10,000 m3))
We are considering the business.
Two drainage pumps were operated yesterday, three were added today, and a total of five were drained, and the drainage was completed on the morning of Friday, 28th.
I'm expecting to finish it.
