In accordance with 33 CFR Subchapter O (Pollution), how often must the Oil Record Book be updated with entries?

🔍 Key Concepts

• 33 CFR 151.25 – Oil Record Book requirements within Subchapter O • The difference between time-based recordkeeping (daily/weekly/monthly) and event-based recordkeeping • When specific oil transfer or machinery operations actually require an Oil Record Book entry

💭 Think About

• Is the Oil Record Book meant to be a running diary by date, or a technical log that documents specific oil-related operations? • Look at the language in 33 CFR 151.25: does it tie entries to the calendar (day/week/month) or to specific operations (bunkering, sludge discharge, ballast, etc.)? • If a vessel does several qualifying oil operations in one day, should they all be recorded separately, or would one daily/weekly note be enough under the regulation?

✅ Before You Answer

• Verify in 33 CFR 151.25 whether the rule mentions "on each occasion" or a specific time interval like daily/weekly/monthly. • Check whether the regulation lists particular operations (e.g., bunkering, ballasting, discharging oily mixtures) that trigger entries. • Confirm that the regulation’s wording focuses on when an operation is performed, not on a fixed schedule tied to the calendar.
