Basic Tanker Operations Practice Test

The initial flow rate for static accumulators recommended by ISGOTT be restricted to

1 m/s 0.5 m/s 2 m/s 5 m/s

Correct Answer:

1 m/s

Explanation:

Starting flow from static accumulators should begin at a conservative speed to minimize static electricity buildup and sudden pressure changes. ISGOTT specifies a start velocity of 1 metre per second. This slow, controlled start lets you verify bonding and grounding, check for leaks, and observe equipment response before increasing flow. Higher initial velocities raise the risk of generating static charges, vapor release, and mechanical stress on hoses, while going much slower is inefficient; 1 m/s is the recommended balance for safety and control.
