What is Abort Point and How You Can Use it For Safe Navigation

65
Abort point Let us face it. There is a huge difference between a passage plan and a good passage plan. The good passage plan is a work of art. You know it when you see a good passage plan. How can we define a good passage plan then ? A good passage plan is the one that has all the information on the chart and yet the chart is not cluttered. It is the passage plan which has all the information marked at locations where it is supposed to be. And it is the passage plan that gives the confidence to the watch keepers about the preparedness of the bridge team. Passage planning But sometimes we either have too less information on the chart or so much that it hides the important information. Now how to place all the information on the chart and yet not clutter the chart ? It all starts with the knowledge of why something is required and what use it can be of. And when it comes to safely executing a passage plan, there are certain rules of thumb. One such rule of thumb is knowing when we can abort a passage plan.  Marking of  "Abort point" help in doing so. In this post we will discuss everything about abort point and also if "point of no return" is any different than that. Let us begin. Abort poin...

    Thank you so much for spending your time on writing this article sir! It's really helpful specially for Junior officers. Looking forward to many more articles. If you could please do write an article regarding anchoring procedures, swinging circle and how to calculate how many shackles to let go with regards to the charted depth. Thank you very much in advance sir! Please share your email address so that juniors like me could seek advice from you.

  • Rahul Dutt August 4, 2016
    Very nice and simple article Sir and moreover you are concentrating on areas of confusion . Sir can you give me more example of point of no return like if there is no problem of falling tide. And in Abort point - For ex we are entering Japanese inland water and just at a single point there is insufficient searoom to turn around after that poinr there is so what will be the case then Kindly reply
    2
    Rajeev Jassal August 4, 2016
    If it is only one point and after that you have sufficient room taking into account the traffic density, no need to mark abort point.
    Rajeev Jassal August 5, 2016
    There are not many example of point of no return and probably that is the reason we hear more of abort point than point of no return.

  • Sailor August 16, 2016
    Hi! Very well written article. Saddened to see that the present generation at sea has to know so much of this theoretical stuff. Most of this is not even relevant to be used on ship. It is purely for academic purpose. How many of us have actually used the abort point on board? Anyways this is a subjective opinion. Company has to give guidelines on this in their BMM which will be full and final!

    Rajeev Jassal August 16, 2016
    Hi thanks for your comment Sir..As you said this is subjective opinion and I really appreciate that. From the comment you seem to be a seasoned sailor and I thought May be I can really learn a thing or two from you in future but could not find your email : ). Hope to have your opinion on other future articles too.

  • Jan May 15, 2017
    Wonderful article! I'm just confuse if you still need an abort point marked on your chart/electronic chart if you have sufficient sea room, example on single point mooring. Do you still need to mark it on your chart?
    2
    Rajeev Jassal May 15, 2017
    If there is sufficient room, there is no need to mark the Abort point.
    Jan May 22, 2017
    Thanks for this clarification. Most of the time we are loading/discharging on SPM and somehow some inspectors are still looking for this abort point. Again, thanks!
  • Pawan June 21, 2017
    Very well written Capt.Rajeev. I am curious if a route to contingency anchorage need be plotted from the abort point from a SIRE point of view. I do understand that it might not be possible to lay it in advance bss traffic, lack of suitable anchoring depth/ ground. Your thoughts..
    1
    Rajeev Jassal June 23, 2017
    No, there is no need to plot the route to contingency anchorage from the abort point.

  • Master-B May 17, 2018
    Capt. you couldn't have explained it any better. Sometimes as navigators we just put in information on charts to simply comply with company procedures and vetting inspection. However, a good passage plan will at one glance give the bridge team a good and comprehensive understanding of the sea passage and confidence in executing the passage plan. Thanks for the article in clarifying the two terms that although are slightly similar are quite different.

  • Anuj Thakur March 23, 2019
    Many thanks for the article. Clears a lot of queries. However, I do have a bit to add to examples of 'point of no return'. Please do correct me if I'm wrong. A ship which is about to enter a canal can be considered at point of no return when it is at enters the canal. Also, a ship which is entering a fairway or channel with shallow depths around is also at point of no return at the entrance of such channel especially if the channel follows a convoy system or has regulatory traffic directions for the channel.

  • Siddharth Deoli April 4, 2019
    Very well written & your blog are always a pleasure to read, giving good practical insights for mariners . With regards to point of no return , I do agree with your take, which is also point of no return but I have a slightly different interpretation as well , Abort point and point of no return should always be used in conjunction , abort point is a point where decision is made to abort the passage and point of no return is a point after abort point beyond which V/L can't proceed with available resources on board. , basically abort point is the amber light and PONR is the red light in the plan eg. edge of 1.4 nm circle in your blog is PONR. There is a far bigger Issue for today's mariners who are getting too bogged down with calculations, numbers , theoretical discussions, acronyms, terminology etc. that they are losing touch with bigger picture ( No fault of theirs, its the industry ) which can only be summarized by phrases ' Good seamanship practice' and 'situational awareness '.

  • Chie June 9, 2019
    Thank you for the information sir. I just want to ask. Is the abort point marked prior embarkation of pilot or can it also be marked while pilot is on board and there is enough room for the vessel to turn? Say for example, in the port of veracruz, there is still sea room for the vessel to turn prior reaching the breakwater while vessel is under pilotage. Can I mark abort point/ponr even during pilotage or it must always be prior pilot embarkation?
    1
    Rajeev Jassal January 14, 2020
    Vessel is not supposed to cross the Abort point without pilot on board...So Abort point need to be after the pilot boarding position.

  • Pattabiraman Sadhasivam January 14, 2020
    This blog is misleading. I hope it's not with understanding but only in the explanation. Abort point is when you can abort the passage, so marking of abort point should be such as to be able to turn vessel safely. Point of no return is where you are committed and cannot abort passage so it should be marked likewise. As simple as that, no need for such a big blog with wrong, misleading and confusing information.
