Propulsion Shafting Services

Nautilas offers a range of propulsion shafting services ranging from computational analysis and optimisation studies to in-situ measurement and complete coordination of alignment procedures. In all cases, our professionalism and the use of high-tech equipment guarantees the success of the assignment. 

 
 
Stern Tube Bearing Contact analysis

Shaft Alignment Optimisation

Using a range of analytical tools and a database of dynamic loading conditions shaft alignment optimisation can be performed in order to minimise the risk of bearing failures and their consequences.

 
6-degree of freedom vibration analysis

Vibration Analysis

Using parametric 3D 6 degree of freedom FEA models we can analyse all modes of vibration of the propulsion system in a realistic manner and in the smallest possible time.

Laser Sighting - Geometrical Measurements

Using state of the art laser sighting equipment we perform bore sighting measurements to identify the current state of the propulsion system of your vessel

 

Strain Gauge Measurements - Torsional Vibrations

We have the capability to acquire strain gauge measurements with the aid of wireless radio telemetry systems for the monitoring of torsional and axial vibrations. Validation of the shaft alignment condition can also be conducted with minimal disruption to the vessels' schedule.  

 

Lateral Vibration Measurements and Analysis

Measurement of lateral propulsion shaft vibration is conducted with the aid of specialised sensors and high speed data acquisition systems. The source of this extreamly dangerous vibration phenomenon can be safely pinpointed.

 

Structural Vibration Measurements and Analysis

Measurements on structures or engines can be acquired with the aid of multichannel vibrometers providing solutions to ongoing and persisting vibration issues.

 

In-Situ Machining Services

Through a network of specialised workshops Nautilas offers the capability for a one-stop-shop service for your alignment isues. From an analytical optimisation study to a laser sighting and complete realignment Nautilas is at your service.

 

On Site Attendance

With or without the use of our equipment we can offer valuable help by sypervising and verifying measurements and processes conducted by the yard or workshop
