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.

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)

Requirements for ocean carriers:

Reduction of fuel consumption and pollutant emissions
Creation of a ship energy efficiency management plan (SEEMP)
Minimal downtimes
Retrofitting projects
- Best benefit-cost ratio
- Accurate predictions for the return on investment
- Training of operators and maintenance personnel

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.
