Maritime security is an increasing concern for the shipping industry and security threats present real challenges to the entire global supply chain. In the years since SOLAS and the ISPS Code set out a dedicated statutory framework for the issue, a new security culture has emerged in the industry which has led to increasing understanding of the subject and best practices to mitigate particular threats. But the threats are always evolving and require constant vigilance. 

The List of Ship Stations and Maritime Mobile Service Identity Assignments (List V) is a service publication prepared and issued, once a year, by the International Telecommunication Union (ITU), in accordance with provision no. 20.8 of the Radio Regulations (RR). As stipulated in Appendix 16 to the RR, this List shall be provided to all ship stations for which a Global Maritime Distress and Safety System (GMDSS) installation is required by international agreement.
