During a client inspection, a vessel’s main engine lubricating oil storage tank was found with an unauthorized homemade clamp that kept the self-closing valve open, violating safety regulations and standards. The modification was made to save time during routine tasks but created significant safety, fire, and environmental hazards. No prior inspections or observations flagged the issue. Corrective actions included searching for similar unauthorized devices, reinforcing safety protocols, and emphasizing that tampering with safety equipment will lead to disciplinary action. Routine inspections and maintenance must adhere to proper procedures without unauthorized modifications, reports IMCA.
What happened?
During a client inspection, the sight glass on a vessel’s main engine lubricating oil storage tank was found to have been fitted with an unauthorized and homemade ‘clamp’. An unauthorized ‘clamp’ was installed on the storage tank without any consideration for the potential consequences. This clamp kept the self-closing valve open at all times, contravening mandatory regulations, and company standards and exposing the crew, the vessel, and the environment to a significant fire, safety, and environmental risk.

Actions taken
- Thorough search to ensure no such other or similar devices are installed;
- Reminded people of their responsibility to maintain a safe workplace and to raise concerns where any safety devices may have been modified;
- Ensured all personnel were aware that tampering with any valves, alarms, safety devices or other approved measures intended to maintain the safety of the crew, vessel or the environment is unacceptable and will lead to disciplinary measures;
