The results will be delivered together with a Report Viewer .
With this tool it is possible to print the results in every format (graph of table) on your own company paper.
Time domain hydrodynamic analysis using Wasim
Non-linear time domain hydrodynamic analysis of fixed and floating vessels
with or without forward speed, including calculation of global motions and
local pressure loading on the vessel.
Wave loads on Vessels with Forward Speed
Wasim is a hydrodynamic program for computing global responses and local
loading on vessels moving at any forward speed as long as the vessel is
not planing. The simulations are carried out in the time domain, but results
may also be transformed to the frequency domain using Fourier transformations.
The program solves the fully 3-dimensional radiation/diffraction problem by a
Rankine panel method. For these methods panel models are required for both
the hull and the free surface. Wasim has its own mesh generator, with the
geometry of the hull being supplied by the user.
Analyzing wave interactions using Wamit
WAMITŪ is the most advanced set of tools available for analyzing wave interactions with offshore platforms and other structures or vessels. Since the announcement of Version 1 in 1987 at MIT, WAMIT has gained widespread recognition for its ability to analyze complex structures with a high degree of accuracy and efficiency.
Design-specific seakeeping data-bases
| Application: | ship and offshore design, system design, ship operation, decision support systems | |
| Customers: | designers, engineering companies, owners, operators, weather routing companies |
Deliverables: design-specific data-bases with custom-made applications, which allow the user to carry out in-house or on-board analyses such as:
- Operability
- Comparison of different designs
- Motion control system configuration and optimization (engineering)
- Voyage simulations and ship routing (operation for just-in-time arrival, fuel consumption minimization, weather routing, damage avoidance)
- Comfort studies
Why AMARCON:
- Our data-bases can be created in an early design phase, but they will have a long-term validity.
- The custom-made applications, which are a natural part of the data-base, allow the customer to use the data efficiently in-house or on-board, not needing the expertise required to actually run the applied seakeeping software
- Only state-of-the-art seakeeping software is used to fill the data-bases.
- The data-bases can be delivered in any format.

Research studies and software development
| Application: | general maritime technology | |
| Deliverables: | reports, software applications |
Why AMARCON:
We have a long experience in applied research and software development, such as:
- The development and implementation of a non-linear 3D program for the calculation of ship motions.
- Long experience in joint research projects (Co-operative Research Ships a.o.).
- Sloshing and slamming studies.
- The development of a statistical method for the calculation of extreme non-linear responses (Most Likely Extreme Responses).
- The development of a non-linear frequency domain program for calculations of non-linear ship responses (based on third order Volterra series).
- The development of a stress component-based fatigue method using non-linear wave load snapshots.
With our large experience both in theoretical and practical seakeeping and wave load projects, we can offer general technical consultancy covering:
- General project co-ordination, either from our offices or from the client's offices.
- Design review (evaluation of the risk for slamming, sloshing, green water, ringing, trapped modes, parametric roll, ...).
- Model test assistance (scope definition, review of model test programs, acting as owners representative during model tests, co-ordination of model test programs, analysis of results).
- Processing and evaluation of full scale measurement data.
- Third party evaluations
