078 Tanker Operation: Removing Liquid-Sealed Condition | Pump Safety & Cargo Handling

In this training video, we focus on a critical safety step in tanker ship operations — the removal of liquid-sealed conditions from cargo pipelines after loading. A liquid-sealed line can lead to severe hazards such as water hammer effects, line ruptures, or pump damage during the voyage, especially in rough seas. You will learn how deck officers and crew must properly drain cargo lines used for loading, ensure that valves are aligned according to the Cargo Control Room (CCR) panel instructions, and confirm that pipelines are free from trapped liquid. This procedure is an essential part of tanker cargo discharge preparation, stripping operations, and pump handling safety. The video also highlights the importance of clear crew communication, accurate marking on the CCR console, and post-departure checks on deck equipment. These practices are consistent with industry standards, NYK operational manuals, and international tanker safety guidelines. Whether you are a cadet, junior officer, or experienced chief mate, this video will strengthen your understanding of safe cargo operations, pump protection, and maritime safety management. 📌 If you found this video helpful, please like, share, and subscribe to our channel for more maritime training resources.
