NOW AVAILABLE: SHAFTDESIGNER - THE INNOVATIVE SOFTWARE FOR PROPULSION TRAIN CALCULATIONS
Welcome to ShaftDesigner, the innovative Computer Aided Engineering (CAE) software which is a great help
for anyone involved in the design, installation, maintenance and repair of propulsion shafts. A practical
user interface with easy modelling features helps create a realistic 3D representation of the shaft line,
while detailed but orderly data reports provide all the information needed by the user, creating optimally
ShaftDesigner was developed by Dr.
Yuriy Batrak of Intellectual Maritime Technologies (IMT) in the Ukraine for
B.V in the
Netherlands as part of their service division in shaft alignment. It was created as a bridge between IMT's
theoretical expertise and Machine
's practical experience in the field of shaft alignment and mounting. Thanks to the software's
capabilities to perform reversed calculations, the theory and practical findings could be cross-validated,
guaranteeing accurate results. In the development of ShaftDesigner there was also a close cooperation with
classification societies and leading OEMs of various components of the propulsion train, in order to meet
The rationale of ShaftDesigner was that further development was needed in the field of alignment software.
Three main problems in current software were identified. The first is the lack of a single shaft model to
perform all types of shaft related calculations. Up to now separate software with different data models for
alignment and for each type of vibration has been used. The second problem is the inability to analyse
different operating conditions from ballast to laden, cold and warm engine and different states from
uncoupled shaft, to fully assembled propulsion trains. The user has always been forced to manage and
maintain many files to achieve solutions in different states. Finally there was a substantial disparity
between modern knowledge in the propulsion train domain and the capabilities of software in use.
An accurate representation of all components of the propulsion train, including engines, gearboxes, bearings
and propellers, is created using details about each element. Because of the easy drag and drop function of
ShaftDesigner, all the propulsion train components are relatively fast to place, to speed up shaft line
modelling. From an engineering point of view ShaftDesigner provides a useful tool to explore offsets to
optimize the position of all propulsion train components based on acceptance criteria set by the user. This
is done in order to, at an early stage, guarantee a good bearing load distribution and thus safe operation
of the shaft line. Because ShaftDesigner can identify this issue in the ship's design phase, possible
time-consuming and costly (re-)alignment problems can be avoided. Also, at this early stage, with the
various vibration modules, it is possible to calculate if a certain lay-out has the potential to create
harmful vibrations and estimate possible alterations which could be necessary.
