One is informed by the owner that two of the vessel's electrically driven centrifugal cooling water pumps will be replaced with two of higher capacity pumps. No modification of existing piping will be involved. What should be your concerns from an operational perspective?

Correct Answer: Option A — Upgrading of circuit breakers and controllers and possible increased erosion of discharge piping due to increased system velocities.

Increasing pump capacity requires verifying that electrical components, specifically circuit breakers and motor controllers, can handle the higher current draw. Furthermore, higher flow rates increase fluid velocity, which accelerates erosion and corrosion within existing piping systems, potentially compromising structural integrity over time as per standard marine engineering maintenance practices.
