Coast Guard regulations require a shipboard oil pollution emergency plan to be reviewed __________.

Correct Answer: Option A — annually only

MARPOL Annex I and 33 CFR 155.1030 require the Shipboard Oil Pollution Emergency Plan (SOPEP) to be reviewed annually. This ensures that contact lists, procedures, and equipment inventories remain current and that the crew is familiar with the latest emergency response protocols for potential oil discharge incidents.
