For cargo operations, what is Part 2 of the ORB focused on?

Part 2 of the Oil Record Book (ORB) is focused on cargo ballast operations. This section is crucial as it documents all operations related to the handling of oil cargo and the management of ballast water, which is vital for maintaining the stability of the vessel.

When a ship takes on or discharges oil, it is required to record the details of that operation, including the quantity of oil loaded or discharged and the time of operation. This information helps in tracking the potential discharge of oil into the sea, which can have significant environmental impacts. Properly maintaining this record ensures compliance with international regulations, such as the MARPOL Convention, aimed at preventing marine pollution.

The other options pertain to different aspects of vessel operations. While cargo operations in port, maintenance operations, and crew training are all important components of vessel management, they fall outside the specific focus of Part 2 of the ORB, which is dedicated to the oil operations as they relate to ballast management and cargo activities.
