A modification to the cargo heating main steam system drain line was not identified during multiple company superintendent’s visits. This resulted in the Wah Kwong Ship Management (Hong Kong) management of change framework, which required that any system modifications be subject to formal risk assessment and documentation, not being effectively applied.
Response by Wah Kwong Ship Management (Hong Kong)
To improve oversight and strengthen management of change procedural compliance, the superintendent’s inspection report will be amended to include verification of any shipboard system modifications not reflected in the ship’s design drawings. These actions are intended to ensure that future modifications to critical systems are properly assessed, documented, and communicated.
ATSB comment
The ATSB acknowledges the above safety action that is intended to ensure future modifications are properly assessed, documented, and communicated. As above, the safety issue will remain open until evidence of the intended action is provided.
