At what age should tank ships undergo a gauge thickness test of holds?

Tank ships are subject to specific regulatory requirements that focus on the structural integrity of their holds, particularly as they age. The prescribed time frame for conducting a gauge thickness test is typically set for vessels that are 12 to 15 years old.

This interval is critical because as tank ships age, they become more susceptible to corrosion and structural deterioration due to the harsh marine environment and the nature of the fluids they transport. Regular assessments during this window ensure that any potential weaknesses can be identified and addressed before they lead to significant issues, enhancing safety and compliance with international standards.

Conducting a gauge thickness test at this age also aligns with the guidelines established by various maritime regulatory frameworks, including those by the International Maritime Organization (IMO). This measure is designed to prolong the lifespan of the vessel while ensuring that it continues to meet safety and operational standards, ultimately protecting both maritime workers and the marine environment.
