The record of oil tank cleaning is documented in the Oil Record Book (ORB), specifically in part 2. This part of the ORB is designated for recording operations related to the transfer, disposal, and handling of residues and wastes. It includes detailed entries concerning all oil tank cleaning operations on the vessel, ensuring compliance with international regulations, and providing a clear audit trail for the management of oily residues.

It's important to note that while the ship's log book may contain some related entries, it does not serve as the primary record-keeping document for oil tank cleaning specifically. The Safety Management System focuses on broader operational safety procedures rather than detailed records of oil handling. ORB part 1 deals with the loading and discharging of oil cargo, which does not cover the specifics of oil tank cleaning activities. Therefore, part 2 is the appropriate and regulatory-required section for such documentation.
