Key to finding the most economical and
environmentally friendly marine equipment whether the entire vessel or
a component is to understand how energy is best put to use.
The Modeling and Simulation module of the Propulsion Engine is the key to unlocking possibilities for improved performance, economy and environmental benefit.
Propulsion Data Services can provide modeling and simulation services
as an initiator of system design as well as provide a reality check on
a system being offered by an independent designer or manufacturer.
There is no clear dividing line
between modeling and simulation. Modeling is a more general type of
analysis which is used to home in on
best practice for a particular application.
The number of options for a vessel design is expansive. Modeling is an effective
method of narrowing down the choices and working toward an optimum
solution.
Some examples of parameters optimized in modeling are:
Life Cycle Costs
Voyage Analysis
Cargo Capacity
Performance
Maneuvering
Noise & Vibration
Vessel Size and Type
Energy Consumption
Propulsion and Auxiliary Machinery
Accommodations and Hotel Loads
Insight into system FMEA
As modeling becomes more focused, simulations come into play.
This is particularly true as more and more systems operate off an
electric grid and are electronically controlled. Simulations are
extensively used by manufacturers of electronically controlled
equipment such as engines, gears and DP systems.
Some examples of optimization and analysis in simulation are:
Propulsion System Response Times
Marine Gear and Shaft Brake Timing
Crash Stops
Maneuvering / DP
Electric Distribution Balance & Protection
Hybrid Battery Management
Peak Shaving
System Faults
The detail that can be attained in simulation is limited only by the
availability of data from equipment suppliers and if necessary field testing.
With an analysis stored in an HDF dataset, post processing can provide additional insight into the model or simulation.
