Pressure Testing On Platform Supply Vessels

Pressure testing is an important step in verifying the safe and reliable operation of dry bulk handling systems on Platform Supply Vessels. These systems use pressure tanks to store and discharge materials such as cement, barite and bentonite to offshore rigs and platforms.

For the system highlighted here, testing at an operating pressure of 5.6 bar / 80 psi helps verify that tanks, valves, piping, connections, safety devices and instrumentation are functioning correctly before offshore operation.

Why is pressure testing important?

Pressure tank systems use compressed air to fluidize dry bulk material and pneumatically convey it through pipes and hoses towards the receiving offshore installation.

Before operation, the system needs to perform reliably under its intended pressure conditions.

Pressure testing helps confirm the integrity and operation of critical system components and can help identify potential issues before the system enters offshore service.

Safe and controlled depressurization

Reaching the required pressure is only one part of the process.

After testing, the compressed air must also be released in a controlled and safe manner. Rapid air expansion during depressurization can cause significant cooling of the outlet piping, while high-velocity airflow through valves, vent lines or silencers can generate high noise levels.

Controlled venting, maintaining a safe distance and using appropriate hearing protection are therefore important during the process.

Reliable systems for offshore operations

Pressure testing demonstrates how individual engineering and safety checks contribute to the reliability of a complete offshore bulk handling system.

For Platform Supply Vessels, reliable pressure tank systems are essential for receiving, storing and discharging dry bulk materials efficiently between shore facilities, vessels and offshore installations.

Pressure testing is not simply about reaching a certain pressure. It is about verifying that the system is ready for safe and reliable offshore operation.
