Diver Fatality During Subsea Lifting Operations 1/2

Note: This incident is still under investigation.
What happened?

During the removal of a spool at 172msw, divers were engaged in lift bag operations to relocate the spool to a wet store location. During the operation a series of events occurred, which resulted in one end of the spool rising off the seabed in an uncontrolled manner. The umbilical of one of the divers was caught in the lift bag rigging causing the diver to ascend with the spool until the spool’s ascent was arrested.
