2022-08-25 00:00:00 The "Marine sludge Calculator" has been created from a mariner to mariners and shipping maritime offices. The application is very useful for marine engineers and Technical departments. The user must provide the daily fuel consumption, and is able to change the sludge percentages and evaporation percentage. The user must write also the maximum sludge burning consumption of incinerator. The output is the sludge production, the quantity which can be evaporated and the time which is necessary for incineration of remain quantity. Wish to find useful and we plan to build more app for seafarers.
