The 7x11” cut out in the vent piping is wild. I can’t think of a reason for that to exist. I wish there was a little more investigation into why it was there, especially after being discovered on four of eight ships in the fleet.
Is it common on smaller vessels to have a common vent pipe for all fuel tanks? I’ve not really seen that.
On the fire response side, anyone have any opinions on the CG requesting CO2 release three and half hours after a team entering the space found the fire to be out? It doesn’t mention whether they had any reason to believe the fire may have relit or still been burning, but just as a precaution.
