Marine Operations Ship-to-Ship Operations:
The Integral Role of the Person-in-Overall Advisory Control Introduction Ship-to-ship (STS) operations are critical processes that enable the transfer of various types of cargo such as crude oil, refined petroleum products and liquefied gas between vessels at sea, or in designated port areas. These operations require meticulous planning, coordination, and adherence to safety protocols and environmental regulations. A key figure in ensuring the success and safety of STS operations is the Person-in-Overall Advisory Control (POAC). This article will explore the intricacies of STS operations and the essential role of the POAC in maintaining the safety and efficiency of these procedures.
Ship-to-Ship Operations STS operations consist of several steps, including pre-planning and risk assessment, communication and coordination between participating vessels, mooring and fendering arrangements, cargo transfer, and unmooring. Throughout these stages, clear communication and collaboration between the vessels and shore-based support are crucial to ensure the safe and efficient execution of the operation.
The Role of the Person-in-Overall Advisory Control (POAC) The POAC is a highly skilled and experienced individual with an indepth knowledge of STS operations, regulatory requirements, and safety procedures. This person’s main responsibility is to serve as the central point of communication and decision-making during the STS operation. Therefore, the POAC collaborates closely with the Masters of both vessels and other involved parties, such as terminal operators and third-party service providers.

Key Responsibilities of the POAC
By Captain Prashant Kumar
1. Risk Assessment and Planning: The POAC conducts a comprehensive risk assessment before the commencement of the STS operation. This assessment involves analyzing the compatibility of the vessels, weather and sea conditions, equipment, and personnel to identify potential hazards and implement suitable control measures. 2. Communication and Coordination: The POAC ensures seamless communication between the participating vessels, tugs, and shore-based support. This individual also coordinates the efforts of various parties involved, guaranteeing that all necessary preparations are made and that everyone is aware of their roles and responsibilities. 3. Supervision of Mooring and Fendering Operations: The POAC supervises the positioning, mooring, and fendering of the vessels, ensuring that they are securely and accurately positioned to prevent any risk of collision, grounding, or other hazards.
4. Cargo Transfer Monitoring: During the cargo transfer process, the POAC closely monitors the operation, ensuring that transfer rates and procedures are maintained within safe limits and that all safety precautions are observed. They also address any issues that may arise during the transfer process, such as leaks, spills, or equipment failures. 5. Emergency Response: In case of an emergency, the POAC is responsible for coordinating the emergency response efforts of both vessels and any other involved parties, ensuring that appropriate action is taken to mitigate any risks and minimize potential consequences.
