On the engineering side, Techno Fysica performs, on a daily basis, all kinds of technical calculations, usually aimed at predicting and controlling vibration behaviour.

For this, we use torsional vibration calculation programs, with report formats which are accepted by the class societies such as Lloyd's, Det Norske Veritas, Bureau Veritas, and other. In addition, we use Finite Element programs for all kind of other calculations, ranging from static calculations (stifness, stress and strength) to dynamic calculations (vibrations, mode shapes and frequency response) .

 Amongst the types of calculations we perform are:

• Alignment calculations (based on the sag & Gap method).

• Lateral vibration and whirling calculations.

• Torsional vibration calculations.

• Resilient mounting calculations.

• Strength and stiffness calculations of components and structures.

• Vibration predictions (natural frequency and response calculations) of components and structures (up to complete ships).

As a result of the accumulation of knowledge on what can go wrong in the design of a mechanical installation, we have recently started to use this knowledge in the design phase of an installation.

Especially in the marine world, ship's owners and charterers are often confronted with problems in the early life of a ship. A number of problems can be recognized in the design phase, if only you know what you are looking for.

Most often these problems are based on a difference in point of view between the builder and the owner. Whereas the builder's biggest interest is in building a ship at lowest costs, the owner should also be interested in lowest maintenance, and highest reliability.

Our assistance is based on looking at the design, and recognizing possible problem areas. These problems than can be corrected whilst still “on the drawing board”.

In addition, we advise a series of measurements to be performed during trials. These measurements are often just a small extension to the normal sea-trial program. The extra costs of the additional measuring program are more than covered by savings on the problems which are recognized and fixed in the early stages of the life span of the vessel.
