| A) The jacket water pressure is maintained lower than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained higher than the sea water pressure in the lube oil cooler. |
| B) The jacket water pressure is maintained lower than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained lower than the sea water pressure in the lube oil cooler. |
| C) The jacket water pressure is maintained higher than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained lower than the sea water pressure in the lube oil cooler. |
| D) The jacket water pressure is maintained higher than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained higher than the sea water pressure in the lube oil cooler. |
