A hidden chemical interaction in a vessel’s bilge system can turn routine cargo and cleaning operations into a serious toxic-gas hazard. According to an IMCA Safety Flash, hydrogen sulphide (Hâ‚‚S) was detected by portable gas detectors in an open area of the main deck during a vessel’s transit back to port. The gas was traced to certain bilge vents with the suspected source linked to mud loaded for a rig. No personnel were injured or suffered ill health, but the incident exposed gaps in anaerobic conditions in bilge systems cleaning, chemical compatibility assessment and Hâ‚‚S monitoring.

A gangway refers to a platform, a walkway or a ramp connecting the ship to land or other vessels and is used as a means of safe access for the crew. The gangway must be properly rigged and maintained to prevent accidents or injuries and to counter the movement from tidal streams, swell, cargo operations and surge movements caused by ships in the vicinity.
Maintaining a ship’s structural condition requires regular surveys and inspections throughout its operational life and the Ship Structural Access Manual is an integral part of this process. These checks help ensure that structural components remain free from damage, such as cracks, buckling, deformation, corrosion, or thickness diminution beyond acceptable limits.


Recent bunker alerts have pointed to a growing presence of high-abrasive fuels containing cat fines in several regions, leading to further cat fines risk. The latest VPS Bunker Alerts confirm this upward trend, which is increasingly contributing to operational challenges and disputes within the shipping sector.
