Direct Answer
Option B: prevent cavitation in centrifugal cargo pumps
The vacuum strip system was developed on oil tankers primarily to prevent cavitation in centrifugal cargo pumps. By removing air and vapours from the suction line, it ensures a continuous liquid flow to the pump impeller, maintaining a positive suction head. This enhances stripping efficiency and protects pump integrity, as described in ISGOTT.
