What is the maximum pressure for supplying the international shore connection at the flange?

• A. 150 psi at the flange
• B. 100 psi
• C. 200 psi
• D. 250 psi

Answer: (A)

The International Shore Connection is designed to be supplied at 150 psi at the flange. This rating protects the ship’s piping and equipment from over-pressurization while providing sufficient flow for firefighting operations. Providing 150 psi matches the connection’s design limits; pressures lower than that would reduce flow, while pressures higher (like 200 or 250 psi) could exceed the equipment’s rating and risk damage.
