Ship Performance Simulations & Operational Analysis
Elomatic Marine simulates ship maneuvering, energy efficiency, and power management to help operators make better decisions and reduce fuel consumption.
Do you know how your vessels are actually performing against their design targets? Ship performance simulations give you a clear, data-based picture of how your fleet operates across different conditions and what it would take to improve it.
We combine CFD-based operational analysis with power management modeling to help shipowners and operators evaluate maneuvering safety, energy efficiency, and the impact of technical changes before committing to them. Our work starts from your actual operational profile and mission requirements, not generic benchmarks.
Key Takeaways
- Ship performance simulations let you compare operational and design alternatives before committing to technical changes.
- We cover both operational analysis, maneuvering, seakeeping, accelerations and power management modeling for energy efficiency.
- Simulations are especially valuable when evaluating alternative fuels, which have lower energy density and affect cargo capacity and range.
- Our analysis defines what your vessels are achieving against their design targets and identifies the most effective levers for improvement.
- We work from your vessel’s operational profile and mission requirements, not generic assumptions.
Operational analysis
Safe and efficient operations depend on understanding how a vessel behaves in the conditions it actually faces. We use CFD simulation to model maneuvering and seakeeping, giving operators and designers verified data on vessel behavior in challenging scenarios.
Our operational analysis covers:
- Maneuvering in tight channels and ports, including shallow water effect modeling
- Crabbing and dynamic positioning capability, combining main propulsors and side thrusters with wind load modeling
- Ship motions and accelerations in rough seas, verified against permitted limits for crew, cargo, and equipment
- Wave making analysis for sensitive areas and fairways
- Wind conditions modeling for superstructure and operational limits
For each analysis, we build a calculation model tailored to the specific vessel and operational scenario. Results give you documented evidence of capabilities and constraints – useful for route planning, port approval, and design decisions.
Power management and simulations
With tightening energy efficiency requirements and the transition to alternative fuels, how you manage onboard power has a direct impact on operating costs, regulatory compliance, and cargo carrying capacity. Our simulation service helps you assess and optimize your powering options before making investments.
We help you evaluate:
- Energy saving measures and their impact on fuel consumption and CII rating
- Battery and hybrid power management configurations
- Alternative fuel options – including LNG, methanol, and ammonia, and their effects on energy storage, range, and cargo space
- Machinery configurations and load profiles optimized for your route and operational pattern
Our process starts by defining your operational profile. We then model your machinery for simulation, including potential enhancements. By running simulations across alternative configurations, we identify the best-fit solution for your specific use case and propose both technical and operational measures to improve efficiency.
Alternative fuels bring complexity because their lower energy density affects how much storage space is needed and how cargo capacity changes. Simulation lets you work through these trade-offs before committing to a conversion.
Frequently asked questions
Operational analysis focuses on how a vessel moves and behaves — maneuvering in ports, stability in rough seas, dynamic positioning. Power management simulation focuses on energy: how fuel is consumed, how different machinery configurations perform, and how alternative fuels affect range and capacity. The two are often run together when evaluating a vessel’s overall performance.
Both. For newbuilds, simulations inform design decisions before steel is cut. For vessels in service, they help assess upgrade options, evaluate alternative fuel conversions, and verify that operations in new trading areas are safe and efficient. We use the vessel’s actual technical data and operational history as inputs.
The main inputs are the vessel’s technical documentation (hull lines, machinery specifications, and propulsion data) and the operational profile (routes, speeds, load conditions, and the environmental conditions the vessel typically operates in). For maneuvering analysis, port layouts and channel dimensions are also relevant. We can discuss what is available and what assumptions we would make if data is incomplete.
Alternative fuels such as methanol, ammonia, and LNG have lower energy density than conventional fuels, which means more tank volume is needed for the same range. Simulation lets you model exactly how different fuel options affect storage requirements, available cargo space, and operational range for your specific route. This gives you a reliable basis for fuel strategy decisions without committing to a conversion first.
Power management simulations can be set up to calculate the impact of different operational and technical measures on Carbon Intensity Indicator (CII) ratings. This makes them a practical tool for planning the operational and technical steps needed to meet annual CII targets, or to assess how a vessel’s rating would change after a planned modification.
