About Us
Dijkgraaf Support was founded by Peter Dijkgraaf in 2013. After initial specialisation in European standard EN 1591-4 and certification by TQ Cert as a European accredited training centre in accordance with EN 1591-4, Dijkgraaf Support began flange training. This in turn led to flange consultancy and flange competency testing in flange management.
Martijn Dijkgraaf joined the team in 2019, helping to expand activities to include crane management.
