Question 55 CEL01 - Chief Engineer - Limited

The Correct Answer is B. **Explanation of Correctness (Option B):** Option B, **33CFR Part 151.25**, is correct because this specific section of the Code of Federal Regulations (CFR) directly addresses the **recordkeeping requirements (Oil Record Book entries)** for ships subject to MARPOL Annex I, specifically regarding machinery space operations (such as ballast discharge, bilge pumping, disposal of oily residues, etc.). The scope described in the question—ships of 400 gross tons or above (other than tankers)—falls squarely under the requirements detailed in 33 CFR 151.25. **Explanation of Incorrect Options:** * **A) 33CFR Part 151.15:** This section is titled "Application and certification of surveys" and primarily deals with when the pollution prevention regulations apply to a vessel and the required survey and certification process (e.g., International Oil Pollution Prevention Certificate - IOPP). It does not contain the specific requirements for how the Oil Record Book must be completed. * **C) 33CFR Part 151.55:** This section addresses **Recordkeeping for barges**. Since the question pertains to ships of 400 GT or above (a general designation usually encompassing cargo ships, passenger ships, etc.), this section is too specific and generally deals with non-self-propelled vessels. * **D) 33CFR Part 151.2070:** This section falls under Subpart C ("Design, Equipment, and Operational Requirements for Self-Propelled Vessels of 500 Gross Tons and Above") and specifically addresses the requirements for **pollution prevention equipment** (e.g., Oil Content Meters and filtering systems). While related to pollution prevention, it details equipment requirements, not the specific procedures for entering operational records into the Oil Record Book.
