Q & A

What is the main topic of the lecture?

The main topic of the lecture is discussing the navigation alarms and safety settings on an Electronic Chart Display and Information System (ECDIS) for NAB 6 midterm.

Who is the instructor of the lecture?

The instructor of the lecture is Second Mate Evaristo Feliciano.

What is the purpose of setting alarms in the ECDIS?

The purpose of setting alarms in the ECDIS is to provide warnings when the vessel is approaching an area of danger or concern to prevent accidents such as grounding or collision with the seabed.

How do you access the monitoring panel in ECDIS?

You access the monitoring panel by selecting the appropriate line of the task list menu on the control panel and activating the monitoring option.

What are the different pages of the monitoring panel?

The monitoring panel has three pages: the root monitoring page, the safety alarm page, and the navigational alarms page.

What is the significance of the 'End of Route' alarm setting?

The 'End of Route' alarm setting is significant because it activates an alarm when the vessel passes the end of the planned route, indicating that the vessel has deviated from the planned course.

What does the 'Out of Schedule' alarm indicate?

The 'Out of Schedule' alarm indicates whether the vessel is ahead or behind schedule. It is set to activate a certain number of minutes before or after a predetermined time.

What is the purpose of the 'Waypoint Approach' alarm setting?

The 'Waypoint Approach' alarm setting is to alert the crew a certain number of minutes before approaching a waypoint, preparing them for the alteration of the waypoint.

What does the 'Out Leg Off Leg' alarm setting refer to?

The 'Out Leg Off Leg' alarm setting refers to the steering course deviation. It alerts the crew if the vessel deviates more than a set number of degrees from the intended course.

What is the safety frame group in ECDIS?

The safety frame group in ECDIS is a setting that defines a safety margin around the vessel's planned route to generate anti-grounding alarms, area alerts, and navigational alarms.

Why is it important to set safety parameters in ECDIS?

Setting safety parameters in ECDIS is important to ensure the vessel stays within safe navigational limits, such as avoiding shallow waters or designated no-go areas.

What is the role of the 'Safety Contour' setting?

The 'Safety Contour' setting defines the minimum depth a vessel should maintain to avoid running aground. It helps in creating a no-go area based on water depth.

What is the difference between 'Shallow Contour' and 'Deep Contour'?

The 'Shallow Contour' defines areas of water that are shallower than a set depth and are considered dangerous. The 'Deep Contour' defines areas deeper than a set depth, usually not a concern for navigational safety.

What is the 'Area Limits' setting used for in ECDIS?

The 'Area Limits' setting is used to define areas that the vessel should avoid or be alerted when entering, such as traffic separation zones, restricted areas, or fishing grounds.

What is the significance of the 'Anchor Watch' alarm setting?

The 'Anchor Watch' alarm setting is used when the vessel is at anchor to alert the crew if the vessel starts dragging its anchor.

What is the 'Off Chart Alarm' and when is it activated?

The 'Off Chart Alarm' is activated when the vessel navigates outside the charted area, indicating that the vessel has ventured beyond the mapped region.

Keywords

💡ECDIS

ECDIS stands for Electronic Chart Display and Information System, which is a computer-based system that displays nautical charts and overlays them with navigational information. In the video, ECDIS is mentioned as a tool to avoid grounding and to navigate safely by setting alarms and monitoring the vessel's position relative to the seabed and other hazards.

💡Alarms

Alarms in the context of the video refer to the alerts set up within the ECDIS system to warn the crew of potential dangers or when certain parameters are exceeded. For instance, alarms can be set for 'end of route', 'out of schedule', or 'approaching a waypoint', ensuring the crew is notified to take appropriate action.

💡Monitoring Panel

The Monitoring Panel is a part of the ECDIS system that allows users to activate and view various navigational alarms and safety parameters. It is crucial for monitoring the vessel's progress and safety, as it includes pages for root monitoring, safety alarms, and navigational alarms.

💡Safety Water Limits

Safety Water Limits are values set within the ECDIS to ensure the vessel maintains a safe distance from hazards such as shallow waters or obstacles. These limits are used to create alarms that alert the crew when the vessel is approaching these limits, thus preventing accidents.

💡Contour

In the script, contour refers to the line connecting points of equal depth on a nautical chart, which helps in understanding the underwater terrain. The video mentions setting safety contour limits to avoid navigating into dangerously shallow waters.

💡Waypoint

A Waypoint is a specific location along a route, marked for navigational purposes. The script discusses setting alarms to alert the crew a certain number of minutes before reaching a waypoint, allowing for preparation for route alterations.

💡Off Leg

Off Leg in the video refers to the deviation from the planned course, measured in degrees. Setting an alarm for off leg helps the navigator to correct the course if the vessel deviates too much from the planned route.

💡Safety Frame

The Safety Frame is a virtual boundary set around the vessel on the ECDIS to monitor its position relative to safety parameters. If the vessel's position approaches the boundary, an alarm is triggered. The script explains how to set and activate the safety frame to ensure safe navigation.

💡Area Alert

Area Alert is a feature within the ECDIS that triggers an alarm when the vessel enters a predefined area of interest or concern. The video script describes setting up area alerts for various types of areas such as traffic separation zones or fishing grounds.

💡Anchor Watch

Anchor Watch is a setting in the ECDIS system designed to monitor the vessel's position while at anchor to ensure it does not drift away. The script mentions setting alarms for the bow and stern of the vessel to alert if the vessel starts dragging its anchor.

💡Sounder

A Sounder is a device that measures water depth. In the context of the video, setting the sounder alarm involves defining minimum and maximum depth values to alert the crew if the vessel enters too shallow or too deep waters, which could be dangerous.

All right Uh Good day gentlemen so we

are now on our week 10 lecture Uh module

2

powerpoint and we are going to discuss

our lecture for Nab

6

midterm so again I am second mate

evaristo Feliciano your instructor for

na six Uh

le So this is now the Uh week 10 and

this is the

Uh the week where we are going to have

our quiz

gentleman So this included week 9 and

week 10 for your

quiz so

our learning outcome is to demonstrate

the basic standard function of eis basic

operation and to describe the root

monitoring alarms by setting safety

water limits and values with respect to

contour and dep related information so

guys We are going to discuss iyung mga

Alert na dapat nating i-set para sa

alarma ng ating nabigasyon Para mabigyan

tayo ng eis ng warning in case we are

Approaching an area of danger or area of

concern where our vessel might have an

accident so iniwasan natin sa sa ecdis

sa ating nabigasyon ay yung tayo ay

mag-round o mabaha o sumadsad sa ilalim

ng dagat sa lupa sa

seabed so in order to do this we need to

open the monitoring panel by selecting

the appropriate line of task list menu

on the control panel so sa control panel

nandiyan yyung tas list so activate mo

lang check mo lang yung ah monitoring

and then ah you will be Uh Uh on the

opening the root monitoring page so ito

Iyung root monitoring page ng monitoring

panel So this is the monitoring panel

guys and this is it will start with

the first page that is the root

monitoring page followed by safety alarm

Page and the last one is the

navigational alarms

page So this We are going to set the

alarm as you can see here on the right

side This is the setting on the root

monitoring page of the alarms which we

have the end of root nakita natin dito

so pagka inactivate yan guys chineck

niyo o hindi pala check yyan ay

inactivate lang

ng

umilaw and that is the activation of the

alarms So ibig sabihin niyan end of root

pagka lumagpas ka na sa root plan

sa wave points mo yan aalarm na yan sa

end of the

rout pagka out of xtd guys is pag

lumagpas ka naman doon sa linya from

your port and starboard may limit yan ah

that is in your root plan so pag

lumagpas ang barko diyan activated yan a

alarma ibig sabihin sumobra ka sa kanan

sumobra ka sa

kaliwa Okay yan Yan yung n of root ay

sumobra ka sa destination mo lumagpas na

So yung out of schedule lalagyan mo yan

pag inactivate mo yan lalagyan mo ng

ilang ilang minuto pag inactivate mo yan

that you are out of schedule So ibig

sabihin ah you are

ahead of schedule o ikaw ay late So

ilang minuto

aalarm Okay so let's say ba 60 Minutes

so 1 hour ahead ka 1 hour late ah alarm

mo iyon okay so that is Uh the limit you

are going to to enter there okay pag

lumiit naman diyan ibig sabihin Okay

lang sa schedule mo okay that is the

limit lang Okay waypoint Uh approach So

ilang minuto if you are Approaching a

waypoint mag-a-ala siya So this is to

prepare you for the alteration of the w

point so nilagyan mo ng limit ah Dapat 5

minutes or 10 minutes before ay kumabig

na ang barko or 15 minutes so It's up to

you ah that will give you an alert Okay

so it will give you an alarm na dapat ay

umiikot na lumiliko ka na Yung way yan

yung likuan natin sa

ating course

line okay now out leg off

leg course ilang degrees yung padpad mo

So if you are steering let's say 00 or

360 lumagas

365 wala Nam 36

5005 lumagpas ka or 355 lumiit ka

lumagpas ka naman

pakaliwa nag 354 aalarm yan nag 006

aalarm yan kasi meron kang off leg Okay

so kalimitan ilalagay diyan yan 5 deg or

10 de masyadong mahigpit yang 5 so let's

say 10 deg of leg depende na sa lugar

kung nasan ka an pag open C it doesn't

matter

ah muna yung off leg lalo na kung maalon

so papatayin mo na lang yan so pagka You

are already in inland Navigation yan

kailangan mo na yan medyo ah marami ng

mga danger Marami ng kalaban diyan Okay

so This is the

alarm that you have to set or activate

according to your Navigation guys okay

and Let's go to the

next Okay we already discussed that Uh

This is the alarm group intended for

turning on and off safety setting of

safety parameter for the alarm

Generation during sailing along route

and according to the schedule so ito na

yan napaliwanag na natin yung mga ibig

sabihin niyan

kanina okay until the oble course aan

kasama yan ha

Okay we we have the safety

alarm Okay safety alarm

page from the monitoring panel select

naman natin Ong safety alarm page So

Here we are going to set several alarms

here or sever several

Uh

alerts or alarm group Okay so let's

discuss

Uh this safety frame group Okay safety

frame group balikan natin ito yan safety

frame group and also the Uh the safety

parameters and also the area alert or

basic areas

Ayan so the safety Uh frame okay pag

inactivate mo to guys Okay ano ang

babantayan niya ito ung babantayan niya

itong tatlo

Okay safety

parameters babantayan niya anti

grounding alarm mo yung areas alert

kasama na rin itong si

navigational alarm Ayan okay So ibig

sabihin yan yung mga areas na pag

tinamaan mo sa mapa aalarm siya ise-set

mo yan so importante Ong safety frame sa

nabigasyon Okay so ito muna unahin natin

kasi ito yung aala rito sa mga ito okay

sa susunod na setting natin Okay safety

frame group extended or setting the size

of the frame which will be used for the

chart area Uh chart data analysis and

for the Generation of the anti alarms

area alerts and navigational

alarms Okay so ano ba yyung

ah frame na ito ito ung frame parang

nilagyan mo ng ung frame ng picture ' ba

ganon nilagy lagyan mo ng frame yung

barko mo So yung barko mo either nasa

gitna Kung gusto mo o medyo nasa likod

banda ng frame so Depende sa setting

nasa ahead 10 minutes ahead so meron

kang Depende sa bilis mo yan so pagka

bumibilis ka lumalaki yan ah yung frame

mahaba pagka bumabagal ka lumiliit naman

yung frame so that is ahead minutes

meron

namang good 10 minutes 12 minut

yan ang usually nilalagay then port ah

anong distance mo sa port and starboard

Ayan and then activate mo show safety

frame Okay so yan yung

ah2 nautical Miles 2 nautical Miles dito

sa kabila naman okay so Maliit lang yan

guys Hwag niyong lakihan niyong lagyan

ng mga 1 mile Masyadong malayo Okay

safety frame then activate show safety

frame pag hindi mo inactivate to okay pa

rin yan kaya lang hindi mo makita yung

kung saan na yun tumatama Bakit uma

alarma no sa maganda naka-set

frame

Okay so Yan po yung ating safety frame

ah on the

Uh on our safety setting of safety

parameter so napakaimportante yan yung

safety frame sa ating ah m safety

alarms Okay ito yan guys Ah ito ang

itsura niyan so nilagyan mo itong harap

pabago-bago Depende sa bilis kasi vector

time ang nilagay natin 10 minutes or in

in time Depende yan sa speed so pag

bumibilis humahaba pagka bumabagal

umiiksi yan Okay hanggang sa maging zero

yan pagka hindi na Tumatakbo ang barko

Syempre wala ng babantayan dahil h naman

tumatakbo So yung ah port and starboard

is normally fix fix yan hanggang ung

likod depende na sa nilagay mo sama na

rin ung likod niyan

Okay

so pag Tin may tinamaan Siya ' ba ito

kasama sa alert to tinamaan to' sumagi a

alarma So bago ka pa makarating doon

nauna na yung yung ah safety frame mo

parang shield mo ito pero syempre

tatagos pa rin diyan aalarm lang okay

so safety parameter group meron kang

safety parameter group is intended for

the setting and viewing of safety

parameters in the Navigation mode so

napakahalaga nito so meron kang check on

scale Larger Than okay ang initial diyan

ay default natin Is 1 is to 300,000 so

Larger Than that checkin niya yung

safety parameter natin Okay Larger scale

than that Okay kayo pa rin ang magse-set

niyan Syempre yun lang ang default niya

1 is to 300,000

Okay then Larger Than that it will check

for the following Okay safety

contour that is Uh for example 30 met So

this is the contour limit o Ian Iyung

nogo area mo that you are Uh you have

the limit of passing that area so pag

tinamaan na yan let's say 30 meters Do

not go beyond that this will be

your that will be your nogo area of and

the depth of course is let's say safety

dep mo hanggang 30 met ka lang if you go

less than that guys you will be in

danger Okay the shallow contour is the

contour pag sinabi nating contour guys

it is an area depth It is just a point

okay tuldok iyan lalim ng tubig so

contour ay ginagawa niya ng area yung

lugar of the same na naka enter dito

Okay so pinagdugtong-dugtong niya yon

para makagawa ng area So yung shallow

contour ay delikado iyan that is will be

the area that you will be run a Okay

usually it is less than the safety

contour so itong setting na to guys ay

medyo Mali yan ang ang shallow contour

ay mas

maliit sa safety contour ang deep

contour ay mas malaki sa safety contour

naman okay yung deep contour so usually

ang deep contour pinakamalaki so itong

setting na to it's

not correct Hindi po yan ang example na

tama Okay data entry lang yan guys kasi

yan ang parang pinaka default niya sa

initially ay 30 30 30 30 pero dapat yan

ay babaguhin according to the to the

situation of the vessel usually based on

the drop okay

and then we have the

anti alarm group now Please check also

the vicinity of of dangerous group in

the setting of safety parameters during

Navigation Okay so nagnanavigate

mo ag hindi mo inactivate hindi alarma

yan So yung safety control gusto mong

isali iselect mo rin yan

so navigational danger nakagi yan Okay

so these are isolated danger yung mga

naka mabababaw na nasa gitna pero may

mababaw pala roon m isolated danger

navigational danger okay Meron land

danger Okay so these are

construction near on the shore na pag

nasagi natin ay delikado Okay so like a

Bridge yan land danger

yan So yung mga mga cables ayan ah It

could be in the land danger or

navigational ah danger Okay aids to

Navigation okay yung mga buya mga

lighthouse yan ah hindi dapat natin

Tatamaan yan mga ags lang yan ibig

sabihin yan yung mga mga ial boid system

that it we see if we see this boy We

will keep it to the right and if we see

this boy We will keep it to the left so

yan yung yal boy system sama iyan A and

B Okay then safety contour in case you

want it Iyung safety contour ma-detect

niya pag tinamaan niya aalarm mo na agad

Okay so These are the safety setting

parameters in the sailing in the

vicinity of dangerous

objects Okay meron naman tayong area

limits in base and additional groups in

in area groups Okay so yan yung area

naman area alert Ayan area alert so

Iyung basic areas nandiyan yan and

additional area so basic areas tab

checkbox assigning danger to Navigation

status so ito mga basic areas natin if

you think this is dangerous to you or if

you want at least to inform you that you

are passing that area dahil area of

concern mo yan not really dangerous but

you want to Uh monitor that pwede naman

i-activate

mo Okay ito traffic separation zone

traffic separation round about okay

traffic separation system round about

two way root traffic gusto mong

ma-detect yan i-activate mo lang Okay so

mga caution area hindi na masyado yan

restricted area ina-activate yan aan no

so precautionary Pwede rin pero hindi na

masyadong ano ina-activate

So you can also select that if you if

you think that is dangerous military

area Syempre submarine Transit dreads

area fishing prohibited fishing ground

ice area Ayan sea plane landing o yan

mga dapat chine-check yan areas to be

avoided yan common yan okay and we have

also additional area so kasama rin to sa

pag-detect ng safety frame ng

barko Okay additional areas

ah territorial sea international marting

boundary Pwede rin yan kung ah gusto

mong malaman o Iyung harbor limit Pwede

rin yyan

So you have to Uh check that if you want

to activate so ito prohibited area

laging naka-activate yan ha so it's up

to the office of the Watch to if he

thinks na merong dadaanan diyan sa area

na yan then you have to activate that

Okay so that is additional areas to be

detected by the safety frame yan guys ha

yung box na nakapaikot sa

barko Okay so we have also in the

monitoring panel Iyung navigational

alarm page yan Okay so Pag binuksan mo

yan this will also be included Uh some

of this will be so included in the Uh in

the safety Uh

Ah yung ating safety frame Okay so Ayun

ah we have Uh the anchor watch setting

Okay the off chart alarm anan we have

the primary secondary difference so

Iyung difference ng primary secondary ah

GPS natin ayan pag normally set na mga 1

mile okay pag more than 1 mile malaki na

yang 1 mile na yan so meron ng Error yan

supposed to be in meters lang dapat ang

difference so Pag lumaki ng 1 mile

malaki na yyan may error na yan Okay so

ancor watch setting naglalagay tayo ng

pag naka nakaangkla na ang barko so

maglalagay tayo ng setting in the bow in

the Eastern ilang meters so pag umusog

ang barko diyan aalarm bow alarm pag

umatras na ng barko ah alarma stn alarm

yan yung pagka yung dito sa likod natin

ay umuusog paatras tayo paharap Okay so

that is the anchor watch Setting alarm

yan no Pwede rin yyan show anchor watch

ring yung nakabilog For when when we are

at anchor sounder alarm when we have the

sounder depth pag inactivate mo and also

sounder depth so Maglalagay ka ng

minimum diyan so pagka umala yan guys

ay aalarm ibig sabihin papunta tayo ng

mababaw Okay so you have to set the

sounder depth either minimum or maximum

so Maglalagay ka ng ilang meters diyan

Syempre halimbawa ang depth mo ay ang

lalim ng drop ng barko nakalubog siya ng

let's say 10 met so lalagay ka diyan mga

15 met o May 5 meters allowance ka pwede

yung ganon so depende na sa officer of

the watch kung anong gusto niya So once

you activate This it will give us an

sounder alarm So It's good to activate

this off chart lumagpas ka na sa mapa

wala na tayong mapa so that is Uh off

chart alarm

Okay so let's see Okay so This is

the the anchor watch alarm Ayan yung

ring if you activate that so agag Ayan

yung ring pag lumagpas ka diyan ah guys

Ayan So it will give us an alarm Okay so

hindi dapat tayo nagda-drugs it's an

indication that the vessel is dragging

Okay Ayan doon sa bilog na inactivate mo

once you are already drop okay pag drop

anchor activate na yon para

naka-synchronize na

siya Okay so let's see if Do we have

still okay yung sounder group aan naman

sa may mga usually mga depth diyan so it

will give us an idea of

Uh of the depth of the area okay para

Iyung ma-set natin Iyung ecos sounder

natin allright

So okay that's it Uh guys so we have

Uh teaching and learning activities

natin lecture question answer that is

our recitation So may recitation na tayo

ngayon may recitation pa rin tayo So

yung recitation is you write down all

the topics that I have discussed in in a

piece of paper or bond paper then you

turn in photo niyo turn in Bahala na

kayo Alam niyo na iyan and also we have

our quiz or assignment So this second

week na naman alternate silang dalawa So

we have our Quiz 2 na Quiz 2 so this the

last quiz in our midterm guys so don't

miss it and it covers Uh module Uh two

week 9 and 10 yyung last week at saka
