Elektryka Morska uses professional engineering software (ETAP) to develop an accurate model of an electrical system on ships or an offshore structure, which enables a detailed analysis of the system. What do we offer?

  • Performing a Power Flow Analysis – this analysis allows you to determine what the power demand will look like in various operating states of the energy system. This allows us to perform an extremely accurate energy balance study showing active and reactive power flow through the electric grid. In addition, the simulation automatically indicates the values of voltage drops on all elements of the energy system. This immediately gives us information on whether power cable cross-sections are correct. Such analysis can be performed for both AC and DC systems. AC Power Flow Analysis, especially in industrial applications, allows us to estimate the size of capacitors to improve the power factor of the electrical system.
  • Performing Short-circuit Analysis – calculations are made for many different energy system operation scenarios, which allows us to estimate short-circuit currents on main switchboards as well as on distribution switchboards, starters, etc., for the most dangerous system operation scenario during which the highest short-circuit currents may occur. Performing these calculations allows us to coordinate protection devices and/or circuit breakers and create TCC charts.

  • Arc Flash Analysis – the analysis is performed for switchboards located in a particular electrical system. This gives us information about electrical arc energy or arc range which can occur during an accident in a switchboard. This is especially important for the safety of electrical staff working next to the switchboard.
  • Harmonic Analysis – analysis performed to verify compliance with regulations and solve potential problems at the design stage of electrical systems containing VFDs and non-linear consumers.
  • Motor Start Analysis – allows us to check the acceleration time of the electric motor, currents flowing during the start period, and to check the impact of the starting motor on the electrical system.
  • Creation of a “digital twin” of the electrical system – the most accurate representation of the system (energy system map). It allows us to:

– verify the operation of the existing system in the event of various failures;

– develop action scenarios;

– simulate system operation prior to adding/replacing electrically powered equipment and estimating their impact on the energy system.

The digital twin should “live” together with the ship – any system upgrades should first be simulated on the digital twin.
