External agencies consider any navigation deficiency as the reflection of ship's management system. Navigator plotting nav warnings Even Oil major companies take the navigation related deficiencies very seriously. For example BP considers any deficiency related to navigation as high risk. A single observation on navigation can fail the BP SIRE inspection. BP High risk observation Navigational safety deficiencies were on the top for past three years for Indian MOU. And when so much is at stake, we cannot afford to have navigation related deficiencies. So what can we do to avoid these deficiencies ? Well the answer is... By knowing what is required and then doing exactly what you know. This guide will look into everything about dealing with the navigational warnings. Lets begin....

    Suppose I am sailing within Navarea I and suddenly the voyage comes for a port in Navarea II, now I neither have internet onboard nor the chartco. Can You tell me how to get all enforced Nav warnings for navarea II before planning passage.

    Rajeev Jassal May 7, 2016
    Amit.. First thing you should do is select the Navarea II in Sat C if not selected. Next you can ask the in force nav area warnings from your vessel's superintendent, who can get it from internet and email to your ship's email. Please let me know if you have any other question.

    Amit May 8, 2016
    Thanks for the reply and the information. Now ,recently I was going thrgh previous vetting reports and i saw an observation stating that navarea warnings were taken from internet source not from the Sat- C EGC. Although the warnings were printed out from the official website of the navarea co-ordinator as per ADRS and the vessel was trading within the same Navarea all the times. What is your view on this observation?

    Glad you liked this Amit. And yes we are aiming to share the practical experiences as there is theory overload on theweb which seafarers do not find a connect with. Thanks for reading.

    Amit May 8, 2016
    Thanks again for the response and for the information. Present company's SMS doesnt say much about Sat-C. Sat-C cache thing is new information for me, I will try it out now. But than again going back to my 1st comment ,when i select navarea 2 in the sat-c i should receive all navwarnings from scratch in next transmission. Cache must be clear before the very 1st transmission of navarea 2 which i would receive....I hope u get my point!!!

  • Amit May 9, 2016
    Thank u very much for sharing your views. Things are pretty clear now. Only thing to see is the Cache clearing process. Makers might have different ways to do it in their equipments.

    Capt.Rajeev good day. Can you please explain procedures to give folio number to the BA chart those folio numbers which could not be found in chartco outfit or catalogue? Or we have to give folio number to chart by ourselves relaying on are covering by chart? many thanks in advance.

    Rajeev Jassal November 11, 2016
    Folios can either be as per the chart number or area. Admiralty has divided the charts in 101 Folios (as per areas). If we feel some chart does not fall in any of the area, the 101st folio is Miscellaneous and that is where we can put that chart.

    MY Question regarding nav warning through NAVTEX, Can i pass search and rescue by areoplane areas ? and If possible what are the areas to be avoided in navtex.. for example Gunnery, Firing, Bombing ?

    Rajeev Jassal November 11, 2016
    Usually the it will be given in the warning itself. If it has something like "Keep clear" to "Maintain a certain distance" we need to be clear of that. If it is not mentioned, then that warning is for information.

  • Jenry October 10, 2017
    Sir what is the proper management of navarea warnings? is it really need to plot those warnings which is covered by your voyage charts? or there is a specified distance in which it is considered not necessary to plot those warnings? thanks

  • ilya kleymenov October 3, 2019
    Which distance from our intended route is required to plot navarea messages on ENC? If it 50 miles away or 150 miles, should i plot this? Is it any requirements for this? Thank you.

  • Ananyo Muhammad December 12, 2022
    First of all, thank you so much sir for writing such a wonderful blog. It was extremely helpful and served the purpose of sharing the practical onboard experiences of handling nav warnings. Just a small question. So, I am using two JRC JAN 9201 ECDIS onboard. As understood from above discussion, we should be using manual updates over user map corrections on ECDIS as it has a large collection of ENC attributes. However, practically speaking, I have the backup ECDIS dedicated for all sorts of route planning, chart corrections ,etc. After planning the route, marking on the user maps, I export these files to my Master ECDIS. That gives a uniformity over both my ECDIS. The OOW is able to see all user map editings, route information exactly the same in both ECDIS. However, I am unable to do the same with Manual Updates. As per your blogs, I have succesfully plotted the warnings using Manual Updates. I am doing it in Backup ECDIS. But to display the same changes in Master ECDIS I'd have to manually plot the same thing again on the Master ECDIS. This is like a double job. On the contrary, whenever I am using the user map function to do the navigational warning correction, I can easily export any updates that I am doing in the Backup ECDIS to my Master ECDIS at one click. Saves a lot of time, gives a uniform display over both ECDIS. But I have a feeling that what I am doing is not correct. Can you please give my your advice and guidance regarding this issue? Thanks!!

    Well explained. Regarding Australian Costal Warnings. It is enough to select Navarea X and the Navtex receiving area (let's say area H) ? Or I have to fill up also the "Fixed Area"? Up to now I couldn't fund any info about the fixed area.
