Question 21 TK02 - Tank Vessel Assistant - Liquefied Gas

The Correct Answer is B **Why Option B ("The designated person in charge.") is correct:** The Declaration of Inspection (DOI) is a critical document required by U.S. federal regulations (specifically 33 CFR Part 156) before a transfer of oil or hazardous material can take place between a tank vessel and a facility. The purpose of the DOI is to confirm that both the vessel and the facility have met all pre-transfer safety checks and procedures. The regulation explicitly requires that the DOI be jointly completed and signed by the **Person in Charge (PIC)** of the vessel and the **Person in Charge (PIC)** of the facility. The term "designated person in charge" (or simply PIC) refers to the individual appointed by the master of the vessel or the facility operator who has the direct responsibility for supervising the transfer operation and ensuring compliance with safety regulations. Therefore, the designated person in charge on both sides must complete and sign the DOI before loading or unloading commences. **Why the other options are incorrect:** * **A) The manager of the shore facility:** While the manager oversees the overall operation, the regulations mandate that the specific **Person in Charge (PIC)** who is directly supervising the transfer must sign the DOI, not necessarily the facility manager (who may not be on site or directly involved in the operation). * **C) The US Coast Guard:** The US Coast Guard (USCG) is the regulatory authority that enforces the requirement for the DOI, but they do not complete or sign the document themselves. The DOI is an operational checklist completed by the industry personnel (the PICs) responsible for the transfer. * **D) The American Bureau of Shipping:** The American Bureau of Shipping (ABS) is a classification society primarily involved in surveying and certifying the structural integrity and compliance of vessels. They are not involved in the day-to-day operational procedures, such as completing the mandatory pre-transfer safety checklist (the DOI).
