CBT VIDEO BOOK

A key element to tank pressure management is venting. This programme describes both PV and HV valves and their functions, emphasising the crucial role of the IG system, from the burner to mast riser. The programme describes the causes of both over pressurisation and under pressurisation, identifying loading and discharging operations as the times of greatest risk. It stresses the importance of structured, formal, written plans for both loading and discharging operations. It describes how plans should be developed through meetings by those involved and highlights essential preparatory tasks and checks.

The aim of the programme is to train deck officers in how to keep tanks at the appropriate pressure to avoid incidents and personal injuries. It raises awareness of how the ship's venting systems work, and how to manage them safely during loading, discharging and in transit.
