There used to be something called the “Marine Index”, this is where things such as what you asked would be reported. No one will ever admit to this existing but it did back in the 80’s. I know this for a fact as when I settled for back pay after a injury part of the settlement was that they WOULD NOT report it to the Index. Also, I grew up on the other side as my Father ran a Tank Barge Company wand we had more an a few discussions about reporting to the Index.
Now a days, I can see this being very illegal but we all know that things exist behind closed doors that the average person never hears about.
