Question 1

The Chief Engineer hands you the Oil Record Book Part I to countersign as OOW/Duty Officer. Your examiner asks: "What should you check before signing?"

Accepted Answer

Verify every entry has a correct date, time and position; that machinery space operations (bilge pumping, sludge disposal, bunkering, OWS operation) are correctly coded against the standard ORB operation codes; that fuel changeover for ECA entry/exit is logged with position/time/date; and that no entries are missing, altered or contradicted by other records. Signing certifies the entries as accurate — false or incomplete entries are a criminal offence in many jurisdictions and a classic PSC detention trigger. ORB falsification is one of the most heavily prosecuted MARPOL offences (significant US/EU fines and criminal convictions for "magic pipe" cases). Reviewing for consistency — fuel changeover logs tying to ECA entry/exit positions, sludge/bilge water quantities reconciling with tank soundings — is exactly what PSC and class auditors check. This question style (examiner hands you a log and asks "how would you review it") is a recurring real oral-exam format.

Question 2

Your examiner asks: "What documentation and equipment does MARPOL Annex I require your vessel to carry, and at what tonnage thresholds?" Give a complete OOW answer.

Accepted Answer

Ships of 400 GT and above must carry an Oil Record Book (Part I, machinery space operations) and a SOPEP (Shipboard Oil Pollution Emergency Plan); tankers of 150 GT+ also need Part II (cargo/ballast operations). All oil tankers and ships of 400 GT+ must hold an IOPP (International Oil Pollution Prevention) Certificate. Oil filtering equipment/oily water separator is required, generally limited to discharging at no more than 15 ppm oil content outside special areas. MARPOL Annex I applies the IOPP Certificate and Oil Record Book requirement to ships of 400 GT and above (oil tankers 150 GT+ for cargo operations, Part II). The 15 ppm discharge limit applies generally; in designated Special Areas (e.g. the Baltic) discharge is essentially prohibited and the vessel must be a defined distance offshore even for permitted discharges. This is one of the most consistently asked OOW questions across examiners (Bates, Insan, Jackson, Thomson all probe IOPP/ORB/SOPEP basics).

Question 3

Your examiner says: "Prove to me you have actually read a SOPEP manual — tell me what it contains." What is the complete OOW-level answer?

Accepted Answer

A SOPEP contains: the master's reporting procedure and authorities to contact (including national contact lists, which must be updated periodically — commonly every 3 months); a list of shipboard officials responsible for combating spills; procedures for reporting oil pollution incidents; steps to control/minimise the discharge; coordination with national/local authorities; and equipment/material lists for spill response on board. SOPEP is mandatory for ships of 400 GT+ (and all oil tankers 150 GT+) under MARPOL Annex I Regulation 37. Examiners regularly ask candidates to demonstrate they have actually read their own ship's plan — common follow-ups include "what do you update and how often" (the national contact list is a common periodic-update item) and "what would you do if SOPEP equipment was deployed during a collision/grounding," testing whether the candidate treats it as a real working document, not paperwork.
