What actually ShaftDesigner does

ShaftDesigner has a modular structure to cover all marine propulsion shafting calculation needs.


Modeler

Provides a 3D environment for simple and rapid creating detailed shafting design model. The model may consist of several shaftlines, engine crankshafts, gearbox, fixed and controllable propellers, stern tubes, brackets, different types of flanges and bearings. This model is the source for all kinds of calculations. Store your models in the Repository for further usage.

The Modeler module of ShaftDesigner builds the model for propulsion shaft alignment, torsional vibration analysis, axial vibration analysis and whirling vibration analysis

Propulsion shaft alignment

Provides all required calculations concerning marine propulsion fair curve shaft alignment and bearing loads. Considers bending in both vertical and horizontal planes, a detailed bearing model with irregular bush shape etc. Implements a full cycle of the shaft alignment procedure: determines current bearing offsets after measuring with reverse calculation, finds best bearing offsets to apply them onboard, checks it with Jack-up test, SAG&GAP, Strain gauges. Additional features: bush contact pressure field, bearing hydrodynamic lubrication, propeller loads, gear tooth loads, hull deflections estimation, technological tolerances.

ShaftDesigner offers the best shaft alignment calculation software on the market. Analize your bearing offsets, search for the optimal bearing offsets and process shaft alignment measurements

Whirling vibration analysis

Takes into account anisotropic bearing model which has direction and frequency dependent stiffness and damping characteristics. Calculates free vibration’s damped natural frequencies, mode shapes, critical and resonance speeds, Campbell diagram. Harmonic response analysis provides all parameters at any section, 3D animation and indicates whether a critical speed will result in harmful vibrations. Whirling vibration depends on the alignment parameters and bearing operational conditions providing a more accurate prediction of shafting behaviour.

Whirling vibration analysis in ShaftDesigner offers all Class required calculations and performs deep study of your marine propulsion installation

Torsional vibration analysis

Generates calculation scheme out of shaft dimensions. Calculates angular deformations between components, vibratory torque and stresses in shaft elements, gear hammering in geared connections, power loss in flexible elements and dampers, normal and misfiring diesel engines conditions. Advanced ice impact and short circuit features provide transient calculations in time domain. Supports the latest Classification Societies requirements.

Torsion vibration analysis is completed easyly with ShaftDesigner. Fast calculations, 99% submission ready reports

Axial vibration analysis

The free axial vibration calculation shows an overview of the various critical speeds with their corresponding mode shapes. Harmonic response analysis shows actual shaft displacement and thrust bearing loads in relation to the running speed of the installation. Different options are available to set excitation, frequency dependent stiffness and damping parameters for all equipment.

Already use similar software?

Using old fashioned or homemade software means some possible risks and inconvenience for the company:

  • Additional development and support budget
  • Restricted functionality and low software performance
  • Frozen or discontinued development
  • Inconvenient unintuitive user interface
  • Time-consuming model creation
  • Manual reporting and graphs making

Eventually the companies replace homemade software with a special continuously supported one. We can provide easy data migration from your homemade software to ShaftDesigner and it is possible to implement an additional functionality to cover your requirements.


Some third-party software packages are too general, complicated and not directly focused on marine problems. Their customers can wait for the requests implementation for a long time and not always successfully. We understand such situations completely and we are here to help your business running smoothly.

ShaftDesigner software FAQ

I'm not sure about the budget.

ShaftDesigner license is perpetual, it means the unlimited usage time. There is no need to pay for unused functionality due to the modular structure of the software. The investment returns after several projects.

Are there any benefits compare to general FEM or simulation packages?

Most of the CAE/FEM/simulation software are too general, that is why require serious engineering and programming background as well as strong user experience. Often it takes a long time to enter initial data and compose the report, this increases the project's hours. ShaftDesigner is dedicated to marine propulsion calculations to reduce working time and efforts.

I'm not a frequent user, I don't have many shafting related projects.

We can provide a 'pay for usage' ShaftDesigner licensing model. Pay for the project time only.

I don’t have enough experience in this field.

ShaftDesigner is friendly for beginners as well as for experienced engineers and researchers. Despite the great functionality, it is extremely easy to make the model and perform calculation. Besides a clear detailed user's manual, we provide support, helpdesk, on-site and online trainings.

I’m not intended to get the software, but I need the calculation report.

We provide a wide range of marine propulsion shafting consulting and all related FEM, CFD and ship theory calculations. Contact us to discuss your project!

What's about support and updates?

We provide 1 year technical support and regular ShaftDesigner software updates for free. The customer support system is available 24/7. Consulting service is also available as an option. After the initial periond of support is terminated, the service contract can be prolonged for 1 year again (2 or 3 years with discount). In case of service contract was not prolonged, fair renewal policy is provided.
