With reference to NSHC conclusion 28, and actions 3/2010, 1/2012 and 8/2016, and considering the need to monitor the implementation of the North Sea Hydrographic Commission’s Member States re-survey plans, the North Sea Hydrographic Commission has established the NSHC Resurvey Working Group (RWG) with the following terms of Reference and Rules of Procedure.
The geographic scope of the RWG is the entire area of the North Sea Hydrographic Commission. The RWG should give due consideration to the Dover Strait / Pas-de-Calais, defined by the areas of the Traffic Separation Scheme (TSS) “North Hinder South” and adjoining TSS “In the Strait of Dover and Adjacent Waters” as adopted by the International Maritime Organization (IMO) and published in the IMO “Ship’s Routeing”. The RWG will give special attention to the routes selected for deep draught vessels passing through the Dover Strait/Pas-de-Calais, published in the IMO “Ship’s Routeing”.
