[Circumstances of Incident]
The accident occurred at a site where fishing
port improvements were being carried out.
Dredging work inside the port was being conducted
as part of the improvement work.
In the morning of the day of the accident,
a grab dredging convoy (a grab dredging vessel,
a slurry barge and an anchor vessel) moved
to the dredging site some 300 meters distant
from the mooring area located on reclaimed
land.
After the dredging convoy completed the installation
of the dredger, workers confirmed the site
where dredging had been carried out the previous
day, and the operator was instructed to make
some 10 to 12 passes with the dredge.
While the victim, who was a deckhand, was
supposed to stand by while this work was
done, he was voluntarily painting the starboard
winch guard that was located within the swing
radius of the counterweight that supported
the dredge's rotating shaft. When the rotating
dredge shaft started to swing, the victim's
neck was suddenly caught between the counterweight
and the steel frame of the winch guard, and
suffered fatal damage to his cervical vertebrae.

[Causes]
The following can be cited as the causes
of the accident.
1 On the day prior to the accident, the victim
and a co-worker had climbed up the port winch
guard to carry out the same type of painting
work. However, as the port side was not within
the swing radius of the counterweight, no
problems had been encountered.
On the day of the accident, however, he was
carrying out the same painting work by climbing
up the starboard winch guard. As this was
located well within the swinging radius,
his neck was caught between the counterweight
and the winch guard when the shaft started
to swing.
2 As the victim was voluntarily carrying
out the work on his own, there were no co-workers
or witnesses present at the time of the accident.
