Question 17 TK01 - Tank Vessel Assistant - Dangerous Liquids

The Correct Answer is B **Explanation of why option B ("Both persons in charge") is correct:** The safe transfer of oil or hazardous materials between a vessel and a facility is a joint operation requiring mutual agreement and coordinated responsibility. Regulations universally require both the Vessel Person In Charge (VPIC) and the Facility Person In Charge (FPIC) to confirm that all pre-transfer safety checks, communications procedures, and regulatory requirements (often documented in a Declaration of Inspection/Pre-Transfer Checklist) have been satisfied. The decision to start the transfer marks the highest point of risk commitment, and therefore, it requires the positive consent and authorization of **both** persons in charge. Neither party can legally or safely initiate the transfer without the documented, verbal, or signaled confirmation from the other. *** **Explanation of why the other options are incorrect:** * **A) The person in charge at the facility:** This is incorrect because while the facility PIC is responsible for the shore side, they do not have authority over the vessel’s readiness, valve alignments, or internal crew readiness. The vessel PIC must agree before operations commence. * **C) The person in charge of either place that is doing the pumping:** This is incorrect because the decision to start is based on safety and readiness criteria (documented on the checklist), not solely on who is controlling the pump. Even if the facility is pumping, the vessel must confirm it is ready to receive flow and vice versa. * **D) The person in charge on the vessel:** This is incorrect because while the vessel PIC is responsible for the ship side, they do not have authority over the facility’s readiness, manifold connection integrity, or line stability. The facility PIC must agree before operations commence.
