The person-in-charge on the dock is called a Loading master-PIC and the person-in charge on the barge will be the Tankerman-PIC.
The person-in-charge on a tanker ship will be the deck officer who monitors the transfer of product in the cargo control room.
All persons-in-charge must have special training in order to obtain the proper credentials such as licensing and endorsement on their merchant mariner documents.
Loading Masters work closely with the marine surveyor in agreeing to the sequence of the transfer.
Federal, state, and local laws must be observed during marine transfer operations.
