What I Learned as an LNG Cargo Engineer Most people think LNG loading is simply the process of transferring cargo from shore tanks to a ship. At first, I thought the same. The terminal has LNG. The vessel has empty…
Common Weld Defects on Ships: A Practical Guide for Marine Engineers and Technical Superintendents Introduction When I first started working onboard commercial ships, I honestly didn’t pay much attention to welding defects. My main concern was whether the repair had…
This article is based on my experience working as a marine engineer on commercial vessels, together with publicly available technical references. It is intended to provide a practical overview rather than serve as a welding manual When I first joined…
A Hatch Cover Is More Than Just a Lid When cadets first join a bulk carrier or container vessel, hatch covers often appear to be simple steel structures designed to keep cargo dry. From a structural perspective, however, hatch covers…
Why Surveyors Always Pay Close Attention to the Forward End Region When junior engineers first participate in a hull inspection, most of them naturally focus on cargo holds, ballast tanks, or the engine room. However, after spending years onboard and…
