Request 'North Sea Activity (NSA)'

For the benefit of the safety of a vessel, her crew and equipment a navigational warning can be requested at the Netherlands Coastguard 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). Navigational warnings will be send by NAVTEX every four hours. See for more information about NAVTEX 'ALRS volume 5'.

In case of questions you can contact Nautical Management of the NL Coastguard, tel. +31 223 654911. 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 ccc@kustwacht.nl

A single transmission costs € 19,96 (in total € 119,76 per day). A start rate of € 32,50 will be calculated. On the bill you will find these amounts, including the costs (€19,96) for withdrawal of the safety message.
