Hello
id there anybody who knows what there's about vibrations in the ISO 13703 standards?

There is not much, and it is mostly "motherhood". Here are a couple of more relevant extracts from ISO 13703, it is general guidance:

***QUOTE***
5.8.1 Piping systems may be subjected to many, diversified loadings. Generally, stress caused by the following factors are significant in the flexibility analysis of a piping system:
a) pressure and pressure variations;
b) mass of pipe, fittings, valves, fluid and insulation;
c) thermal expansion or contraction due to process conditions, temperature cycling, venting and ambient changes;
d) external loads and dynamic effect such as hydraulic shocks, wind, discharge reactions, vibration and earthquake. Protection from blast over-pressure may need consideration in certain cases;
e) terminal loads and movements, and other restraints in the piping system.
Piping systems shall have sufficient flexibility to ensure that they do not leak, distort, fail, or overload valves and connected strain-sensitive equipment such as vessels, compressors and turbines. Flexibility and stress analysis of the piping systems should be carried out to satisfy the criteria in accordance with ASME B31.3.

9.4 Piping supports
Platform piping should be supported on racks, stanchions or individual stand-offs. The location and design of supports are dependent upon routing, media, mass, diameter, shock loads, vibration, etc. Consideration should also be given to seal-welding supports to minimize corrosion and to providing sufficient clearance to permit painting. Valve supports should not interfere with removal of the valve for repair or replacement. Piping flexibility and support requirements should be in accordance with ASME B31.3. See 5.8 and 8.3.7 for further information.
