A vacuum breaker for a tanker vessel is a safety device designed to prevent the formation of a vacuum in the cargo tanks during loading and unloading operations. It allows air to enter the tank when the pressure inside decreases, thereby preventing structural damage to the tank and ensuring safe cargo operations. This device is crucial for maintaining the integrity of the vessel's hull and preventing potential accidents due to pressure imbalances.
To perform a vacuum breaker replacement, follow these steps: Shut off the water supply to the vacuum breaker. Remove the old vacuum breaker by unscrewing it from the pipe. Clean the area where the old vacuum breaker was attached. Install the new vacuum breaker by screwing it onto the pipe. Turn the water supply back on and test the new vacuum breaker for leaks. Remember to follow any specific instructions provided by the manufacturer for your particular vacuum breaker model.

That would depend on the application as there are many uses and shapes and specifications for a vacuum breaker
A vacuum breaker does not allow back flow into the potable water system A syphon breaker is normallly installed on a tank that there is a possibility of the tank imploding
Tanker vessel certificates are required as per the Flag state requirements which is as per the statutory certificate list,and complying solas,marpol and loadline,tonnage and class rules.
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
A Pressure Vacuum Breaker (PVB) on an oil tanker ship is designed to maintain proper pressure and prevent vacuum conditions in cargo tanks during loading, unloading, and transit. It operates by allowing air to enter the tank when a vacuum is created, thus preventing structural damage, while also venting excess pressure to avoid over-pressurization. The PVB features a spring-loaded mechanism that opens at specific pressure thresholds, ensuring safe and efficient cargo handling. This system is vital for maintaining the integrity of the tank and preventing spills or leaks.

A vacuum breaker is a device that prevents water in a toilet cistern or water tank, from syphoning back into the toilet cistern or water tank.

A vacuum breaker is usually installed at the top of a vertically-mounted drain pipe leading to a drain. The water drainage hose from an appliance such as a dishwasher or washing machine should never be plumbed directly into a drain stand pipe without a vacuum breaker. The vacuum breaker prevents contaminated water from the drain being sucked back into the appliance if it has a fault.
