(DG 9723). This considers additional design options for the fuel
oil system, as well as optional heat exchangers for better viscosity regulation
when changing between HFO/LSHFO and MDO/MGO.

4.6.1
Fuel oil system components
The following components are associated with a fuel oil system of maximum fuel
flexibility, i.e. operation on heavy fuel oils and distillates, as indicated in
. Therefore, the following section considers a fuel oil viscosity of 700 cSt at
50
°C.
In cases where only distillate fuels are considered, the system can be simplified
(as explained in section
), however consideration must be given the
reduction in fuel oil viscosity.
