ectus awareness series 3 chart depth setting very important for grounding prevention
2
good morning third mate good morning captain how's it going very well sir we have no traffic
3
and the weather is good that's good i am looking forward to our port call tomorrow morning me too sir
4
Very good.
5
Our arrival draft is 9 meters, and the coastal and port area may have many shallows,
6
so I would like to reconfirm the ECDIS chart depth settings on the arrival ENC.
7
Aye, sir.
8
Here you go, sir.
9
Thank you, third.
10
It looks good.
11
Our chart depth settings are in order.
12
Third, do you know the importance of the ECDIS chart depth settings?
13
Yes, sir.
14
They are important.
15
These settings organize the display of safe depths and unsafe depths.
16
Yes, that is correct.
17
There is no traffic and the weather is good.
18
How about we refresh our knowledge about chart depth settings?
19
Yes, sir.
20
That would be great.
21
Contours, as you know, are lines on a chart that join equal depths or equal heights.
22
Chart depth settings refers to the value inputs by the user for the shallow contour,
23
Safety Contour Safety Depth And Deep Contour Yes, sir.
24
But, sir, how are these values decided?
25
Good question, third.
26
The ship's master decides the values of the chart's depth settings as per the ship manager's guidelines.
27
But the first important thing to understand is how the ECTIS selects the contour for display.
28
Most ENC cells usually only contain depth contours such as a 2 meter, a 5 meter, a 10,
29
15, 20, 30, 50 meter,
30
etc. The ECDIS is programmed to display depth contours equal to input values or the next higher available contour.
31
For example, if the safety contour input is 15 meters, a 15 meter contour will be displayed.
32
If a 15 meter contour is not available, the next higher 20 meter or higher contour will be displayed.
33
Another example, as in our case, we have an input of 13 meters, but ENC does not have a 13 -meter contour,
34
so the ECTIS will display the next higher available contour, such as a 15 -meter.
35
I could understand it very well.
36
I will explain the display with each type of depth contour and safety depth in a default setting of four -color display.
37
the shallow contour outlines the shallow waters of high grounding risk
38
depth less than the shallow contour is shown in blue color
39
the vessel should never enter this area corresponding to the safety depth settings depths
40
that are equal to and lesser than the safety depth will be shown in black bold fonts
41
and soundings deeper than the safety depth in gray color the vessel must not plan passage over black bold soundings
42
however if needed a vessel may do
43
so only after confirming UKC in compliance with the ship managers
44
guidelines the safety contour is the separation line between navigable water depths and depths less than the safety contour.
45
The safety contour's value is.. equal to
46
or greater than the safety depth waters between the safety contour
47
and the shallow contour are shown in light blue color as per regulations the ecdis should give an alarm
48
if within a specified time set by the mariner his or her own ship would cross the safety contour
49
usually a vessel does not plan a passage across the safety contour towards the depths
50
that are less than the safety contour however
51
when necessary a vessel may do so only after confirming the ukc
52
and marking the no -go areas in compliance with the ship manager's guidelines
53
third let me share another important information about the safety contour
54
and the isolated danger mark the generic isolated danger mark symbols identify the navigational dangers
55
that have safe passing depths less than
56
or equal to the safety contour setting it is important to note
57
that the safety contour setting governs the display of the isolated danger mark symbols.
58
By default, all ECDIS display these symbols only for the dangers that lie on the deeper side of the safety contour.
59
When these dangers lie on the shallower side of the safety contour setting
60
or when these dangers have depths greater than the safety contour setting, they are displayed with a black dotted line around them.
61
However, do take note that on some EGDIS, such as in the case of the Furuno and JRC EGDIS,
62
the user can select a setting to show isolated danger generic symbols, also on the shallower side of the safety contour.
63
Therefore, the user must make the correct safety contour setting on the EGDIS.
64
In addition, when planning courses or navigating in the vicinity of such dangers.
65
Please check their details in advance by clicking on the respective symbol which will open the additional information about the dangers.
66
Thank you, sir.
67
This was indeed very useful and important information.
68
The deep contour outlines the limit of deep water set by the user.
69
Waters between the deep contour and the safety contour are shown in grey colour.
70
Waters deeper than the deep contour are shown in white colour.
71
Now, let us look at the kinds of colour displays available in an Ectis.
72
The Ektis has two kinds of color settings, two -color and four -color.
73
By default, the Ektis shows a four -color display.
74
We have seen the four -color display with the earlier explanation.
75
Now, let us see the two -color display.
76
Yes, sir.
77
The two -color display is simpler and it shows navigable and depth areas less than the safety contour in two colors.
78
The two -color display is preferred by pilots and navigators, especially in shallow waters and during night navigation.
79
The two -color display gets enabled by selecting the two -color depth setting.
80
In this display, the light blue color from the four -color display is replaced by the blue color.
81
Thus, the area between the safety depth and the zero depth is shown in a single blue color.
82
The gray color from the four -color display is replaced with white color.
83
The white color indicates safe waters with depths greater than the safety contour.
84
In some cases, one may be able to navigate beyond the safety contour, but must keep clear of the depths less than the safety depth,
85
indicated in bold black font.
86
Sir, now I understand the difference between four color and two color displays very clearly.
87
i hope you found this discussion useful yes indeed i could
88
refresh my knowledge of charge depth setting thank you very much sir
89
Thank you.

Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
