NDE Procedure / Scheduling:
(NDT)
The HSE have decided to concentrate on the
existing requirements for having a NDE schedule available for all
rides. This is not a new requirement, but it is now something that
they will be looking for during their normal visits to fairs and theme
parks.
A list of all areas and components of a ride that needs to be
inspected using NDE procedures, and at what interval these tests
should be carried out.
The precise areas required to be tested and possibly the level of
strip down needed to achieve this, should be identified and listed,
preferably by the original designer, but advice may also be sought
from Inspection Bodies (IB's) or other experts who may have the
competence to predict areas that may be subject to fatigue failures.
The schedule should contain instructions regarding the intervals at
which this NDE needs to be carried out. Again this should preferably
be (or have been) drawn up by the original designer, but advice may
also be sought from IBs or others who may have the competence.
It is fair to say that experience forms a certain part in all of
this, but anyone developing a schedule will need to understand where
fatigue might occur regarding the particular device, and in what
timescale it might occur.
There will certainly be some instances where basic fatigue
calculation will also be required. Anyone working out such
calculations should be certain that he is suitably competent, to
carry out any calculations required.

LTC (IB) has completed
numerous NDE schedules / procedures for varying sized amusement
devices from looping coasters to juvenile kiddie rides.
