Crude oil tankers often carry different grades of oil in the same tanks, so it’s essential to wash them before loading new cargo. Previously, they were cleaned by seawater, but this method increased marine pollution and required bigger slop tanks to store leftover residue and oily water mixture. For these reasons, the Crude Oil Washing…
Pumps are mechanical systems that move liquids by increasing fluid pressure to overcome gravity, friction, and system resistance. Most industrial pumps are centrifugal (rotodynamic) or positive displacement, with roughly 80% being single‑stage, end‑suction centrifugal models used across many shipboard and shore applications. Proper pumping operations and adherence to procedures for ballasting, deballasting, cargo transfer, and…
LNG carriers require a thorough preparation process after dry dock to ensure the cargo tanks are safe and ready for loading. This involves a series of critical steps, including filling the insulation spaces with nitrogen, drying the cargo tanks to remove moisture, inerting them to create a safe atmosphere, gassing up to replace inert gas…
Artificial Intelligence (AI) is changing the way ships are run. Recent reports say AI is now an important tool that helps make work at sea safer and more efficient. While traditional seafaring skills are still very important, seafarers also need to learn how AI works, where it is used on board, and how to use…
Proper preparation of LNG carriers for dry docking is essential to ensure safety, maintain operational efficiency, and comply with regulatory requirements. This process involves several critical steps such as stripping, warm-up, gas freeing, inerting, and aeration, each of which must be carefully executed to prevent hazards and preserve the integrity of the cargo tanks. Continuous…
