The safe operation and functionality of pressure vessels are maintained through a combination of regular maintenance checks and hydrostatic testing, making the correct answer a comprehensive approach involving both methods.

Regular maintenance checks are essential for identifying any wear and tear, corrosion, or defects that may develop over time. These checks not only ensure the vessel is operating within safe parameters but also uphold compliance with regulatory standards. Routine inspections help in catching potential issues before they become serious problems, thus preventing malfunctions and accidents.

Hydrostatic testing complements these checks by evaluating the integrity of the pressure vessel under actual operating conditions. This testing involves filling the vessel with water and raising the pressure to a level that exceeds its normal operating pressure. By doing so, it helps to identify leaks, weak points, and structural weaknesses that may not be apparent during visual inspections. Hydrostatic tests are typically performed at specified intervals as mandated by regulatory standards to reaffirm the vessel's safety.

The combination of both regular maintenance checks and hydrostatic testing creates a robust safety protocol that addresses both preventive and proactive measures, ensuring that pressure vessels remain safe and functional throughout their operational lifespan.
