Simulation in Marine Engineering

You are aiming for efficient designs and engineering and want your ships and marine technology to be safe, eco-friendly and economical to operate? For analyses and optimizations of ship systems, the multiphysics simulation software SimulationX is the tool of choice.

Energy efficiency in marine engineering

Whether you evaluate various design layouts for new developments und retrofitting projects or whether you assess potential weak points of ship systems that are already in operation – ESI ITI’s engineers support you along the way from concept studies to design and system analyses to safety compliance certification. System integration is our core competency. System simulation with our simulation software SimulationX is the tool of choice.

  • Design reliable lubrication systems inside engines and gearboxes

    Simulate the oil-circulation system for lubricating combustion engines and gearboxes with SimulationX and the new model library “Hydraulic Lubrication”. Examine whether the chosen design provides sufficient lubrication at the desired bearings with respect to heat input, heat transport and other influencing factors.

  • Simulate electric machines, which serve as generator or motor, without the need to have detailed knowledge in electrical and controls engineering

    With dedicated circuit models, which are easily parameterized with catalogue data and the desired automatic controller action, design engineers can simulate the behavior of electric machines interacting with mechanical and electrical components. Electrical engineers benefit from ready-to-use circuit models for efficient and easy modeling, simulation and detailed analyses of the power electronics and controls in electric machines.

    Shipbuilding: market requirements and trends

    Stricter environmental regulations, fierce competition and new areas of application (e.g. in arctic waters or in deep sea mining) are the challenges shipbuilders and ocean carriers are facing today. And this holds true for the entire lifespan of ships and marine equipment. Also special purpose vessels for erecting and operating offshore wind farms or for deep sea oil and gas extraction, for instance, require innovative and reliable technologies for drive systems and superstructures.

    This is the starting point for new concepts that can deliver the same or even higher level of reliability, availability and efficiency. If you are able to see the full picture of the underlying physical principles and interactions, you are in the best position to meet the specific maritime requirements and prevail in the global competition.

    Modeling and simulation of vessels

    For economical operation and compliance with regulations and standards for environmental protection and energy efficiency, smoothly operating ship systems (main and ancillary units, cooling water and fresh air supply cycles, waste heat recovery systems etc.) are imperative. In order to meet such requirements, renowned manufacturers, classification societies and engineering service providers in marine engineering around the globe have benefited from ESI ITI’s simulation software SimulationX and engineering services for years.

    SimulationX – software for the development of vessels and marine technology

    The following scenarios are typical areas where SimulationX can be used:

    • Structural analyses of ship propulsion systems and occurring torsional vibrations including effects from ice impact
    • Evaluation of operating strategies and system layouts for main and ancillary units to increase a ship’s energy efficiency
    • Safety and reliability studies (FTA, FMEA) as well as virtual tests of the powertrain, the energy supply and the controller layout
    • Realistic, physically correct models for training simulators
    • System analyses of HVAC systems

    Preventing damage to the powertrain under arctic conditions with SimulationX

    Did you know that the model element “Marine Propeller with Ice Impact” from the simulation software SimulationX was certified by Germanischer Lloyd (GL)? Designed and developed by ESI ITI in collaboration with GL in accordance with the specifications laid down by GL, the Finnish-Swedish Maritime Administration and the IACS, this model element helps you calculate ice impact induced loads in the powertrain fast and reliably. The simulation results can also be used for safety cases as part of certification procedures.
