IHO invites your feedback on Draft S-44 Edition 6

30 July 2019

In 2008, the International Hydrographic Organization (IHO) published the 5th Edition of its Standards for Hydrographic Surveys (S-44). Hydrographic technology and methodologies have evolved considerably since that time. In 2017, recognising the need to revise and update the publication, the IHO Hydrographic Services and Standards Committee (HSSC) established the HSSC Project Team on Standards for Hydrographic Surveys (HSPT), tasked with reviewing and then revising S-44. 

As part of this work, and with assistance from the International Federation of Hydrographic Societies (IFHS), the HSPT conducted an online questionnaire which gauged the views of S-44 users, stakeholders and the wider hydrographic community. Now, the IHO has asked for our help once again; this time, to collate comments and feedback our national societies and our individual and corporate members on the Draft S-44 Edition 6.

It is hoped that this revised version of S-44 will have relevance beyond the traditional safety of navigation surveys conducted by or on behalf of national Hydrographic Offices. The HSPT are, therefore, keen to hear the views of the widest possible cross-section of survey practitioners, including those involved in surveys for ports and harbours, renewables, cables and pipelines, oil and gas, dredging and those using remotely operated vehicles and remote sensors for surveys.

The Chair of the HSPT reports that the entire document has been rewritten with the aim of preserving the philosophy of previous editions as well as updating the content. Notable differences include:

To assist with your appraisal of the draft, HSSC Project Team members Iain Slade (UK) and Jean-Guy Nistad (Germany), who are also both active within IFHS, have kindly offered to answer any queries you may have.

Please forward your views to IFHS, by email to helen@hydrographicsociety.org, by Friday 18th October 2019.
