102 Tanker Ship Operation – Tank Pressure Control Explained | Inert Gas & Safety Procedures

Описание: In this training video, we explain tank pressure control on oil tankers, a critical aspect of safe cargo operations and maritime safety. During a voyage, a mixture of inert gas and petroleum vapors exists in the tank’s ullage space. These gases expand and contract with changes in temperature, cargo condition, and weather, leading to fluctuations in tank pressure. Proper control of this pressure is essential to prevent structural stress, equipment failure, or hazardous situations on board.

This video covers:
Why tank pressure control is vital for safe tanker operations.
Steps to release excess pressure through common vent risers while ensuring flame screen integrity.
Precautions for toxic or H₂S-rich cargoes, including work suspension and safe crew positioning.
Use of inert gas systems (IGS) for topping up tanks to prevent negative pressure.
Best practices before venting gases such as checking wind velocity, avoiding lightning conditions, and notifying the engine department.

Following guidelines from OCIMF, ISGOTT, and tanker operation manuals, this video is designed for maritime students, cadets, deck officers, and tanker crew who want to strengthen their knowledge of cargo operations.
