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.

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 of vessels

Requirements for shipbuilders:

  • Inexpensive and fast development of ship systems and components
    Flexible to meet customer requests
    For special purposes, such as active heave compensation
    Virtual commissioning of components, modules, vessels and controls
  • Optimal concepts for cutting-edge ship propulsion systems
    Tailored to specific application requirements
    With minimal operating costs
    Analysis and comparison of alternative drive concepts (LNG, electric hybrid etc.)
  • Development of energy efficient vessels
    With frequency-controlled pumps
    Waste heat recovery systems
    Optimized operating strategies for main and ancillary units
  • Safety cases for certification procedures
    Torsional vibration analyses for powertrains (TVA)
    Safety cases for control systems
    Safety cases for generators
  • Development of ship systems with minimized downtimes (safety and reliability studies, FTA, FMEA
  • Compliance with environmental regulations
  • Energy Efficiency Design Index (EEDI)
  • Compliance with limits for pollutant emissions, especially for emission control areas (ECAs)
