Reference Answer
### Introduction
The fundamental difference between the cargo pumping systems of a chemical product carrier and a crude oil tanker is driven by the nature of the cargo. A crude oil tanker typically carries large, homogeneous parcels of one to three grades of cargo. In contrast, a chemical product carrier is designed for maximum segregation and versatility, often carrying numerous small, incompatible parcels of high-purity and often corrosive chemicals, each requiring its own dedicated system to prevent cross-contamination.
