Request for a Navigational Warning

For the benefit of the safety of a vessel, her crew and equipment a navigational warning can be requested at the Netherlands Coastguard Centre in Den Helder. Sometimes this is even compulsory as mentioned in the issued license. This is also mentioned in the Mijnbouwbesluit, the Shipping Regulation Territorial Sea and SOLAS V agreement of 1974 (Safety Of Life At Sea).

In case of questions you can contact Head Nautical Management of the NL Coastguard Centre, tel. +31 223 658315. In the weekend and after office hours contact can be made via the Duty Officer of the NL Coastguard Centre, tel. +31 223 542300 or e-mail
