How often must steam-propelled ships take water indicating paste cuts on idle fuel tanks?

Steam-propelled ships are required to take water indicating paste cuts on idle fuel tanks monthly. This process is crucial for ensuring the integrity of fuel storage and safety on board. Water indicating paste helps in detecting the presence of water in fuel tanks, which can lead to contamination of fuel and potential engine issues. By conducting these checks monthly, operators can identify problems early, manage any accumulated water, and maintain the overall health of the fuel system. This regular monitoring is essential for effective maintenance and operational readiness. The frequency of monthly checks strikes a balance between thorough oversight and practicality, allowing crew members to keep up with the maintenance schedule without it becoming overly burdensome.
