Question 59 OSV02 - Mate - Offshore Supply Vessels

The Correct Answer is B. **Explanation for Option B (The designated person in charge):** The designated person in charge (DPIC) holds the ultimate responsibility for the safety and efficiency of the oil transfer operation, which includes ensuring strict adherence to all established and posted transfer procedures, regulatory requirements, and pollution prevention guidelines. The DPIC is the designated authority on site for the transfer and is accountable for the proper execution of the entire operation. **Why the other options are incorrect:** * **A) The tankerman:** While the tankerman (or persons assisting the DPIC) performs the operational duties of handling the hoses, valves, and monitoring tanks, their primary role is operational execution, not overall procedural supervision. They follow the direction of the DPIC. * **C) The oiler:** The oiler is generally a junior rating responsible for assisting with specific tasks, particularly those related to machinery or auxiliary systems. They do not hold the supervisory or legal authority to be responsible for ensuring the posted transfer procedures are followed. * **D) The senior able seaman:** Similar to the oiler, the senior able seaman is a crew rating. While they may be experienced and involved in deck operations, they typically do not possess the certification or delegated authority required to be the Person In Charge legally responsible for compliance during an oil transfer operation.
