X62DF-S2.0
4.7.2 Fuel oil system with only MDO/MGO or MGO
If the main engine is designed for only MDO/MGO or MGO fuel oil, the system
may be simplified in comparison to the conventional system specified in section
4.7.1,  4-68.
The changes are as follows:
• The fuel oil mixing unit is omitted.
• The fuel oil end-heater is omitted, along with the associated viscometer and
control logic.
• The simplified fuel oil filter arrangement like that in arrangement 'B' is ap-
plied.
Additional optional changes:
• The feed pump and booster pump can be replaced with a single delivery
pump. If this option is selected, the pump must be located in the recircula-
tion piping and must not be too high relative to the fuel oil tanks (see ()H
in Figure 4-50). This must be in accordance with manufacturer’s specifica-
tion.

liquid fuel with a sulphur content up to 0.10% (ultra low sulphur). Please
refer to section 4.4.5,  4-26.
