notice to mariners

The Annual Summary of Admiralty notices to mariners is divided into two parts:

1. NP 247(1)

2. NP 247(2)

What are the contents of NP 247(1)? 

In this publication the contents are in two sections namely –

Section 1 – Annual Notices to Mariners                                                                                                             

Section 2 – Temporary and Preliminary Notices

Starting with an index which consists of a note displaying that the current annual summary replaces the previous one, which should be cancelled and destroyed, the first section deals with annual notices for the current year for e.g. an edition of 2013 of Annual summary would deal with notices applicable till the end of year 2012 comprehensively.

A detailed index of notices is provided regarding navigational importance with respect to the British Isles, along with vital information about tide tables, suppliers of admiralty charts and publications, safety of British ships in event of war crisis, voluntary reporting schemes, firing practice areas, mine laying operations, protection of historic, dangerous and military wreck sites etc.

The publication also includes an exhaustive list of traffic separation schemes and information related to ship routeing system shown on admiralty charts. It contains port state notifications issued under the EU Directives and some parts of ship navigation related regulations issued by the United States. The annex provided with the notice contains extracts from the US navigation safety rules.

The second important section of the navigation publication contains a numerical index of temporary and preliminary notices which are in force since the end of the previous year. The index is preceded by further detailed description of each notice mentioned in it, thus enabling mariners to check any chart or any T & P correction applicable to the chart right from its edition date. This information is significant for mariners to keep a track of any previous notice that has been missed out, cancelled or not in force any further. Mariners can thus always refer to the Annual Summary and keep their navigational chart folios up to date.

Important Notes: Often during Oil Major Inspections observations, navigational charts are found marked with Temporary and Preliminary notices which are no more in force or have been cancelled or some notices are found missing. Thus while preparing for such inspections, the ship’s navigating officer can always refer to Annual Summary of Notice to appraise the status of corrections before planning passage in order to keep navigational charts up to date.
