For which vessels is the Oil Record Book Part II maintained?

The correct answer pertains to the requirements established under international regulations for oil pollution prevention. The Oil Record Book Part II is specifically maintained on oil tankers that are 150 gross tons and above, as well as on non-oil tankers that carry 200 cubic meters or more of oil in bulk. This regulation ensures that there is adequate documentation of any operational discharges or incidents involving oil to facilitate accountability and compliance with pollution prevention measures.

The purpose of the Oil Record Book Part II is to track the handling of oil and residues on board, including details on loading, transferring, and discharging oil and oil residues. This documentation is essential for environmental protection and helps in identifying potential violations of pollution control regulations.

In contrast, vessels that do not meet the specified size requirements or the volume of oil transported are not obligated to maintain this particular record, which focuses on ensuring that larger operators have stringent record-keeping to mitigate oil pollution risks. This regulatory framework underscores the importance of oversight in maritime operations, particularly for vessels that have a higher potential impact on marine environments due to their size or the nature of their cargo.
