Answer:

When discharging dirty ballast from an oil tanker at a high flow rate with main cargo pumps, the limiting factor on permitted overboard discharge is the instantaneous rate of discharge of oil.

Instantaneous rate of discharge (l/nm) = oil content (ppm) x flow rate (m3/h) / speed (knots) x 1,000
