What is the purpose of the Shipboard Oil Pollution Emergency Plan (SOPEP) and when is it invoked?

• A. To coordinate response actions in case of an oil spill, and it is invoked immediately after a spill is detected or suspected.
• B. To coordinate response actions in case of an oil spill, and it is invoked only after a formal accident report.
• C. To record daily maintenance tasks and is invoked at the end of the voyage.
• D. To manage crew welfare during emergencies, invoked when crew requests.

Answer: (B)

SOPEP is the on-board plan that organizes how a ship responds to oil pollution. Its purpose is to coordinate actions by the crew and with authorities to contain and mitigate an oil spill as quickly and effectively as possible, reducing environmental impact.

It is activated as soon as oil pollution is detected or there is a credible indication of a spill. The master (or person in charge) initiates the plan, starts containment and cleanup steps, and notifies the required authorities and contacts listed in the plan. The key point is immediate response—the plan is not held until a formal accident report is filed. The plan also provides the structure for who communicates with whom and what information to provide, but activation is driven by the detection or suspicion of pollution, not by a subsequent report.
