HNS Correspondence Group Blog

The Correspondence Group, established by the IMO Legal Committee, advocates for the ratification of the 2010 HNS Protocol through information and experience sharing. The Group has Mr. François Marier from Canada as its coordinator and its principle means of communication are by email and through the HNS Protocol Blog. Furthermore, this Blog, which is maintained by the IOPC Funds Secretariat, is also an effective means to see all communications, respond or comment on postings and view documents or web links. To be added as a contributor to the Blog, please contact Mrs Victoria Turner at the IOPC Funds
