We had raised the ship from the water for a long time, so the tree shrinks and creates gaps.
So when we lfoat the ship on water, water gets through the gaps in the board.
We will do a variety of tests to safely operate the boat after work.
Today we got to work while paying attention to heat stroke.

	We are preparing to raise a ship with a crane
	Let down the repaired ship to water
	We raised the boat to be repaired the next time with a crane
	We investigated the flood condition of the repaired boat
	Boat's plate is shrinking by drying
	We are putting water in a newly repaired boat
	When water enters the boat,check the water leak
	We shake and tilt the boat floated in the water to check for water leaks
