This document provides an overview of cargo handling on offshore units. It discusses the scope of cargo handling, which includes materials, supplies, personnel for operations and maintenance, but excludes production fluids. It describes the external flows between offshore units and onshore bases, as well as internal flows onboard units. Examples of cargo handling equipment like cranes, vehicles, and hoists are presented. The document outlines the analysis of cargo handling throughout design phases from concept to detail design. It also discusses interfaces with other engineering disciplines and applicable rules and standards.
