  • Detailed tracking and reporting of fuel consumption broken down by: fuel type, consumer and ship operational state;
  • Up-to-date electronic record of ROB inventories;
  • Consumption balance monitoring and registration of discrepancies between reported fuel additions and measured fuel consumption.
maritime voyages management panel


An energy efficient voyage can bring significant savings in fuel costs. Marorka Voyages identifies speed profiles that result in minimized voyage costs for given routes and ETAs. As a result voyage planning is simpler and voyages are more economical.

Marorka Voyages enables energy efficient voyage planning based on simulations, modelling and ocean forecasts. In addition, that maximizes energy efficiency while making sea passages. As a result it also enables minimizing fuel consumption and costs for the voyage, as well as harmful emissions.

The application optimizes planning by continuously calculating the most efficient speed of the ship during the sea passage. Hence the ship’s officers can then use the proposed speed profile to reduce fuel consumption.

trim data panel


Trim helps the bridge team reduce fuel consumption. It does that by providing recommendations on the optimal trim that will lead to minimized hull resistance. The application also enhances understanding of the relationship between trim, loading and propulsion energy consumption. The result is an overview of these important operational parameters and their effects on performance.


Applying the optimal trim can deliver significant fuel savings.

report management screen


Report management combines automatically logged operational data with manual entries on report forms. This is automatically done when registering information about the ship’s performance and other operations. Consequently it reduces manual input and limits the errors that are inevitable while creating reports.


The information in submitted reports can then be used on-board or sent to Marorka Online for further analysis.

data and energy management view


Logged data always goes through a process of quality control. That is performed before Marorka Onboard stores the data permanently in the platform database. The accuracy and precision of measurements are important factors to consider. Therefore all the data used by Marorka Onboard to calculate the ship’s performance and energy management is quality checked. Most noteworthy, the Marorka Onboard platform has built-in features to detect missing values and to filter outliers and corrupted values.


Data management includes powerful analysis tools. These are used for graphically trending and comparing real-time operational values over a period of time. As a result the crew can locate focus areas for improving energy efficiency and for saving fuel.

First step towards Fleet Performance Monitoring, based on manual data entries.

Marorka Reporting

MARORKA REPORTING is an application that helps in tracking and improving vessels energy management. It works on-board and allows crew to collect and store data in a range of reports.


Marorka Reporting divides each voyage into typical sections (maneuvering, sea passage, canal passage, etc.). It therefore allows for appropriate reporting logic in each case. Furthermore, data is transmitted from the vessel to shore as each report is submitted and stored in a secure data center. Finally, Marorka Reporting provides a framework for basic performance analysis.

Marorka Reporting

The foundation for online fleet performance monitoring. MRV compliance.

An improved flow of information between ship and shore helps to find the most efficient way to operate ships based on accurate data. Hence, knowing the vessel’s performance leads to increased energy efficiency.

Performance optimization and effective energy management are long-term operations. Therefore data must be collected for several months so that a ship’s fuel consumption can be analysed at different speeds and in different conditions. Finally, best results will be obtained with continuous communication and consultation between ship and shore.

Marorka Reporting provides a foundation for online fleet performance monitoring, which can lead to MRV compliance.
