Determine and Set Safety Parameters ll Shallow, Safety & Deep Contours ll ECDIS ll Passage Planning

This video serves only as a guide or reference for determining and setting safety parameters. It shows a complete guide on how to determine shallow contours, safety contours, safety depth, and deep contours. It explains the difference between safety contour and safety depth. Always follow the company procedures on how to determine those safety parameters.
In Electronic Navigational Charts (ENCs), contours represent lines connecting points of equal depth or height in the water or on the sea floor. These contours provide a visual representation of the underwater terrain, helping mariners to understand the shape and characteristics of the seabed.

mate your content is so helpful.
Hello could you please make videos on TRS (dangerous semi circle etc),how to resolved cocked hat.Thanks

[@nauticalacademy001]

Thank you. I will make a video about TRS.

How to calculate the capacity of spaces available for loading cargo? Can you make a video about jt? If so, it would be grateful. Thanks.

[@nauticalacademy001]

Yes I can. Thank you for the comment.

HELLO, THANK YOU FOR THE EDUCATIONAL VIDEO. CAN I ASK YOU TO SEND A COPY OF THE TABLE FOR CALCULATION SAFETY SETTINGS?

[@nauticalacademy001]

Thank you for watching and for your kind words. Unfortunately, I'm not onboard at the moment, so I don't have the table on hand. However, I'll reach out to some of my colleagues who are currently onboard to see if they can provide me with a copy. Once I receive it, I'll be happy to send it to you. Thanks for your understanding!

[@DallasThirteen-re3qq]

@@nauticalacademy001 I apologize, I just wanted to remind that if there is an opportunity, please share the table for calculating the safety settings. For educational purposes I would like to practice on it and check my calculations that I did manually, this will help me. Thanks in advance!

Good day.When we calculate safety depth which tide we minus MLW or MHW?

[@nauticalacademy001]

Typically, the safety contour is established by considering the lowest astronomical tide (LAT) or mean low water springs (MLWS).
Mean Low Water Springs (MLWS) represents the average lowest water level that occurs during spring tides over an extended period. Spring tides occur when the sun and moon are aligned, causing higher high tides and lower low tides. Using MLWS as a reference provides a conservative approach to ensure that the charted depths are sufficient for navigation under most tidal conditions.
So, in the context of determining the safety contour, you would subtract the anticipated tidal range from the charted depths based on MLWS or a similar reference level to ensure safe navigation during varying tidal conditions.

[@sebuhihesenzade8268]

​@@nauticalacademy001It means that when we find Safety depth/contour=Dynamic draft + Catzoc+UKC-HoT(MLWS) I'm I right?

Is it possible to send me a copy of excel you used for the calculation?

[@nauticalacademy001]

yes.

Hello, very informative video, thank you for this job. Could you send me your excel file too? It is very very useful. I would be most grateful.

Could you explain which speed i need to take into account for squat?
