Upgradeable server solution

Marorka Onboard is a server based solution, consisting of data acquisition boxes and workstations.
Marorka services come in a selection of three sizes. This selection provides scalability and flexibility to the Marorka system covering the needs of having a simple performance system to a large scale holistic decision support system.

  • Marorka Basic
  • Marorka Standard
  • Marorka Advanced

The hardware is selected to endure the harsh conditions aboard ships. We deliver Marorka Onboard with all the connectors and controllers needed to integrate with meters and networks.


Robust infrastructure

Marorka Onboard provides core functionality that is extended with additional applications covering specific areas for energy efficiency improvements. Products can be selected on a case-by-case basis, thus maximizing return on investment.
If your ship is connected to the Internet, Marorka Onboard takes care of sending your data to Marorka Online.


Data integrity

Reliable collection of accurate and detailed performance data is the foundation for improving a ship’s performance. Reliable data is essential to determine the current operating status and to monitor if progress is really being made in improving performance.

  • REPORT MANAGEMENTReduces manual input and limits the inevitable errors inevitable while creating reports.


Take action and improve


Machinery identifies ways to improve the operation of all onboard machinery systems. Machinery optimization is focused on the following tasks:

  • Monitoring the efficiency of electricity production and consumption as well as the overall efficiency of the on-board electrical grid.
  • Improving the efficiency of electrical power production and consumption by managing generator loads and reducing unnecessary use of electricity.
  • Providing specialized analysis and advisory support for increasing the energy efficiency of individual systems such as waste heat recovery processes, cargo pumps and refrigeration.

Fuel manager provides an up-to-date reading of the remaining-on-board (ROB) status. It also generates emission reports and maintains a consumption balance audit record between fuel added and actual measured consumption. Key features include:

  • 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.


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, making voyage planning simpler and the voyage more economical.
Marorka Voyages enables energy efficient voyage planning based on simulations, modelling and ocean forecasts that will maximize energy efficiency while making sea passages. Fuel consumption and costs for the voyage are minimized, as are harmful emissions.
Voyages optimizes planning by continuously calculating the most efficient speed of the ship during the sea passage. The ship’s officers can then use the proposed speed profile to reduce fuel consumption.



Trim helps the bridge team reduce fuel consumption 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 by providing an overview of these important operational parameters and their effects on performance.
Applying the optimal trim can deliver significant fuel savings.

  • Optimization of dynamic trim
  • Monitoring of hull performance

Report management

Report management combines automatically logged operational data with manual entries on report forms when registering information about the ship’s performance and other operations. 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 management

Quality control of logged data is performed before Marorka Onboard stores the data permanently in the platform database. The accuracy and precision of measurements are important factors to consider, and all the data used by Marorka Onboard to calculate the ship’s performance and energy management is quality checked. 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 for graphically trending and comparing real-time operational values over a period of time, which will assist the crew in locating focus areas for improving energy efficiency and for saving fuel.
