Hello @Mhaque
Not really. This consumption cannot be deducted as per current DCS regulations.
On the reporting form it should seem as a prolonged ballast voyage with relatively short distance travelled.
Regulatory provisions to deduct fuel exist only in regards to CII calulations, as corrections on CII most importantly for consumptions for cargo heating/discharging (oil tankers scope).
In any case, fuel consumption of any origin and for any means, should be fully reported.
