An important task of the Transport and Water Management Inspectorate (Inspectie Verkeer en Waterstaat) is to have vessels that fly the Dutch flag observe the (inter)national legislation. Certification is an important means to that purpose. This task is mainly boarded out to seven recognized classification bureaus, which are supervised by the Shipping Inspectorate. 
The Shipping Inspectorate carries out the inspections for law enforcement.

The Transport and Water Management Inspectorate can be reached:

Telephone: +31 (0)70 456 45 00
Telephone: +31 (0)70 456 46 50 (Port State Control)

When you dial one of these numbers during evening hours and weekends, an answering machine will give a number of a pager of the inspector on duty. You will be contacted as soon as possible after dialling that number.
