Crude oil tankers, Control of flow rates during loading

On crude oil tankers, cargo flow rates can be particularly high, potentially generating very large hydrodynamic forces and extremely high transient pressures that the cargo handling system may not designed to resist. There have also been many occasions where poor control of flow rates has resulted in overflow of cargo tanks during loading. Targeted at Operational and Management level, with special focus placed on practical learning, deck officers who successfully complete this module will take an important step towards reaching a competence standard of being able to control flow rates during cargo operations.

Crude oil tankers are designed to transfer cargo at a high loading rate, but the operation must be conducted in a controlled manner. If not, large hydrodynamic forces with high transient pressures can develop that the cargo handling system may not be designed to resist. The aim of this module is to give deck officers serving on crude oil tankers the practical knowledge necessary to maintain effective control of the cargo flow rate during cargo loading at high rate on a crude oil tanker.
