Quality
De Ruijter STM’s Quality policy:
Quality control will always be performed according (client approved) Inspection Test Plans (ITP). We
warrant the project management by recording it in the Inspection and Test Plan (ITP).
Our selected partners are all certified to ISO 9001, ISO 3834-2 or EN 1090-2, their welding
procedures are certified according to EN 15614-1.
We continuously check the procedures of our selected partners, so we can put out the quality plan.
Our knowledge is maintained by up-keeping the latest rules of applicable classification bureaus,
such as for example: Lloyds, GL, DNV, ABS.
De Ruijter STM owns their own quality measurement tools, such as a theodolite, leveling
instruments, laser range-finder, etc. to ensure that an appropriate final inspection can be performed.
Processes like grid-blasting are being checked, to ensure e.g. conservation & atmospheric conditions
(on roughness, film thickness measurement, temperature / dew point, etc.).
De Ruijter STM BV has extended experience in measuring the geometry of large steel
structures & wheel positions of cranes, using theodolite.
All measuring instruments are calibrated annually.
De Ruijter STM continuously works on improving quality and work-methods.
