| A motor vessel has three centrifuges to pre-treat the fuel which can be configured to operate in series, parallel, and series-parallel. A large quantity of water is determined to be present in the fuel. How would you configure the centrifuges to deal with this problem? |
| A) Run all three centrifuges as purifiers and decrease throughput. |
| B) Run two centrifuges in parallel as purifiers discharging to the third one in series as a clarifier. |
| C) Increase 'shoot' cycles and run two centrifuges in series as purifiers. |
| D) Drain settling and service tanks more often and run two centrifuges in series, purifier and clarifier. |
