HNS Incident Scenarios Presentation Tool

The HNS Incident Scenarios presentation has been developed by IMO, the IOPC Funds and ITOPF in close consultation with the International Group of Protection and Indemnity Associations and is complementary to the brochure “The HNS Convention: Why it is Needed”. The presentation is intended to be a further resource and information tool for authorities in IMO Member States as well as for the industry stakeholders to highlight the risk of HNS incidents and make ratification of the Convention a priority.

The presentation can be downloaded here.

HNS Blog

The HNS Blog was originally established to support the Correspondence Group, established by the IMO Legal Committee, to advocate for the ratification of the 2010 HNS Protocol through information and experience sharing. The Group’s principle means of communication were by email and through the HNS Protocol Blog which was maintained by the IOPC Funds’ Secretariat. In April 2017 the IMO Legal Committee considered that the HNS Correspondence Group had completed its mandate and decided not to extend it further. However, given the success of the blog the IOPC Funds continues to maintain it and encourages States and interested stakeholders to use it as a forum to exchange information on developments and activities relating to the entry into force of the 2010 HNS Convention. To be added as a contributor to the Blog, please contact Mrs Victoria Turner at the IOPC Funds at:
