HFO – heavy fuel oil tanks

|
Service and settling tank
To ensure fuel feed to the main engine, the separated heavy fuel oil (HFO) is first pumped into the settling tank (buffer tank). The connected service tank (day tank) is filled via continuous overflow from the settling tank and is connected directly with the main engine. Heating coils in both tanks ensure an even temperature between +75° and +90°C (+167° and +194°F) which keeps the oil pumpable.

Level measurement with VEGAFLEX 61
The heavy fuel oil stored in the service and settling tank has a high storage temperature and contains a number of different chemical compounds. Sticky oil vapours make the level measurement very difficult. The VEGAFLEX 61 guided microwave sensor easily masters this problem. It guarantees a reliable measurement from the top. The space-saving mounting of the cable version makes it the ideal level measuring instrument for all heavy fuel oil tanks.
