Question 60 OSV02 - Mate - Offshore Supply Vessels

The Correct Answer is B **Why option B ("Part I (Machinery Space Operations)") is correct:** The requirement for an Oil Record Book (ORB) on passenger vessels over 400 gross tons is mandated by MARPOL Annex I (Regulations for the Prevention of Pollution by Oil). Routine entries related to the operation of the vessel's propulsion and auxiliary machinery (such as ballast water handling, sludge disposal, bilge water discharge, bunkering of fuel, and transfer of oil within the ship) are recorded in **Part I (Machinery Space Operations)** of the Oil Record Book. Since a passenger vessel does not carry oil as cargo, its routine oil operations are exclusively associated with its engine room and machinery spaces. **Why the other options are incorrect:** * **A) An Oil Record Book is not required on this vessel:** This is incorrect. All ships over 400 gross tons (except oil tankers, which have different requirements) and all oil tankers over 150 gross tons must carry and maintain an Oil Record Book Part I (Machinery Space Operations) under MARPOL Annex I regulations. A passenger vessel over 400 GT falls under this requirement. * **C) Part II (Cargo Oil/Ballast Operations):** This is incorrect. Part II of the Oil Record Book is only required for oil tankers, as it specifically documents operations related to the handling of oil carried as cargo (loading, unloading, cleaning cargo tanks, etc.). A passenger vessel is not an oil tanker and does not use Part II. * **D) Part III (Emergency Discharge/Spillage):** This is incorrect. While the ORB may contain instructions or forms related to emergencies, the standard MARPOL ORB only consists of Part I and/or Part II. Furthermore, any discharge or spillage, regardless of location, is not a "routine entry"; it is an unusual event that must be recorded in the relevant section (Part I or Part II) immediately, often involving special procedures beyond routine logs.
