Ship was loaded with phosphate.
This is a weird one.
There was a fire in the engine room.
Owners claimed that this led to explosions that sank the ship.
Insurers claimed that the sinking was caused
by an "unexplained ingress of sea water"
which had nothing to do with the fire.
Case was settled on technicalities,
so we have no idea what really happened.
IMO has the date a year later.
