“During the months we have used this software application, we have calculated shaft lines for various type of ships such as passenger vessels, ferries, tankers and container ships with a remarkably higher efficiency than before,” says Dr. Arnulf Berndt.

The SCHOTTEL group is an innovative group of companies specialising in the development, design, production and marketing of azimuthing propulsion and manoeuvring systems, as well as complete propulsion systems with power ratings of up to 30 MW for vessels of all sizes and types.

Main products are rudder propellers, twin-propellers, pod drives, pump jets, thrusters and controllable pitch propeller plants. The headquarters of the group is located in Spay, Germany near Koblenz. SCHOTTEL is a global company with subsidiaries and agencies worldwide. The company was looking for a suitable shaft calculation package for a long period and decided finally for the program ‘NAUTICUS Shaft Alignment, extended’ in the beginning of 2005.

SCHOTTEL gave the following reasons for selecting Nauticus Shaft Alignment:

1. The three traditional calculations of shaft alignment, axial and whirling vibration are integrated in one software
   module, which makes it possible to create one model for all three calculations.
2. The software is issued by an independent and world-wide acknowledged company. Therefore we do not expect any further need of explanation about the software regarding the approval of shaft alignment and shaft vibration results independent from the fact which classification society is responsible for the particular approval process.
3. We expect the software will be updated regularly.
4. Generating of models can be done quite fast in an easy dialog. The program is mainly self-explanatory and
   flexible, i.e. shaft model updates as well as other versions may be created very easily from existing models.

Fincantieri, Trieste, Italy,
Massimiliano Cella
“Fincantieri has a tradition in shaft line alignment calculations since the end of the 1970s. Since we carry out our own calculations, it is important for us to have up-to-date software to do the job. The clear Windows interface and the DNV software have made the difference in our choice.”

DOOSAN Eng. Co.Ltd, Korea,
I. S. Ha
“The NAUTICUS shaft alignment software is very sophisticated, easy-to-learn and well proven. The user-friendly GUI, designed based on DNV’s know-how and long experience, closely matches our needs for calculation of shaft alignment and whirling vibration.”

“The user friendly approach and simple way of operating the program makes NAUTICUS Shaft Alignment calculation very interesting to us.”

DNV Houston, USA,
Paul Martin
“We at DNV Houston are consultants to companies working with high speed vessels driven by Gas Turbines. In this connection we have need to check the shafts for lateral vibration (Whirling Vibration). We have used this tool which is very ‘user friendly’, performs the calculations very fast, and presents the results in a manner that can be sent as a report with little or no input from the author. As a package these programs are very useful for those working with machinery systems. The shafting that needs to be analysed with respect to strength of gears, and shafting, in addition to vibration and shaft alignment, need not be limited to marine systems.”
