CG3 – Cargo 3

Cargo 3

This exam consists of a written test comprising descriptive questions and requires the ability to draw vector diagrams of loads on cargo gear. The exam is three hours in duration. To grasp the required concepts in cargo work, you must have a strong foundation in ship stability and construction.

Cargo level 3 requires you to know detailed aspects about the various types of cargo and specific carriage requirements and safety precautions for individual cargoes. You must be aware of the various behaviours of these cargoes in terms of operating a safe and stable vessel. The exam is for prospective near coastal masters and master mariners, as such it requires in depth knowledge and expertise on all aspects of cargo operations.

You must be able to perform loading and discharging calculations: safe working loads (SWL), stowage factor, broken stowage, etc. Compared to Cargo level 2, this exam has greater emphasis on chemical and oil tankers and their operations. Related calculations and extensive knowledge of these cargoes and the vessels that carry them is required.
