Azimuths are tabulated from North or South towards East or West. Amplitudes are tabulated from East or West from North or South.
Step 1 – Observe suns bearing on the celestial horizon note it with the time of observation.
Step 2 – We will have to find the time in GMT so that we can use the time in Nautical Almanac.
Step 3 – Find Declination, (if the value is increasing, the d correction is to be added otherwise subtracted.)
Step 4 – Find LHA
Step 5 – Compare observed azimuth to calculated azimuth. Compass Error is the difference between the two values.
Tan Z = (( Cos DEC ) (Sin LHA)) / ((( Cos Lat ) ( Sin Dec )) – (( Sin Lat) ( Cos Lat )( Cos LHA)))
If LHA is More than 180 than it is entered as negetive. If Dec and Lat are contrary name,Dec is entered as a negetive. If Z is negetive add 180 degrees.
Here you can get semester wise questions papers, Finally they made this available. All the best for your semester exams.
I am thinking of writing my day to day experience so that people know how it feels in merchant navy line. Yes making videos will be more convenient for you guys to watch but that is a bit time consuming but i will definitely start making videos.
It is very fascinating as it offers 6 month of job and 6 month of rest or free time. But the actual story is quiet different initially as a deck cadet i will get a contract of 9 Months (+- 1 month). And this is really a long time almost a year. So it is going to be difficult as i never stayed away from home for this long. Have stayed Maximum of 6 months and that felt long at the end.
There are so many Questions poping in my mind right now.
- Is Merchant Navy a Right choice ?
- Is it a good choice for long term like 10-12 years?
- How it feels on board?
- Work culture?
- Away from family & friends for 9 months?
Answering all these questions require Experience, So what i will basically do is wait & experience things.And put everything on this blog column of the website and even try putting videos for everyone.
DPA – Designated Person Ashore – Any Matters with regard to safety of the vessel, Individual or environment can be directly brought to the notice of the DPA.
When DPA is not reachable due to any reason, The Alternate DPA(ADPA) has to be contacted.
CSO – Company Security Officer – For any concerns in security of the vessel the CSO has to be contacted.
When CSO is not reachable, ACSO is to be contracted.
Present freeboard port = 1.68cm
Stbd side = 1.79m
Water of RD = 1.017,
Tropical SW freeboard = 1.63c
Tropical SW draft = 9.6m
FWA = 150mm
TPC = 20.4
For, Port Side = (3 -2.8) = 0.2m
= 20cm (above )
For , Starboard side =( 2.9 – 2.8) =0. 1m
= 10cm above
Hence ,Mean freeboard can be calculated as
= (20+ 10)/2
= 30 /2 cm
= 15cm available
As we know:
Change in draft =
(Change in RD )x(FWA)
= (1.025 – 1.020 ) x 20 /0 .025
Now, Total sinkage = (15 + 4)cm
TPC = 30( given)
TPC = (A/ 100) x density
30 = (A/100) x 1.025
A = 30/ 1.025
Again for calculating ,TPC at RD 1.020
= (A/100) x ( 1.020)
= 29.85 t/cm
Now , Cargo can be load =( TPC x sinkage)
= (29.85 x 19)
= 567.15 t
Starboard winter load line = 60mm above
Port winter load line = 20mm below
Mean draft = ( 60 – 20)/2
Summer SW draft = 7.2m( given)
We know that:
Waterline (W) = (1/48 of summer draft)
=(1/48 x 7.2)
Total sinkage available to bring the vessel to her tropical load line = ( 2+ 15 + 15)
TPC =20( given)
So, Cargo can be load = (TPC x sinkage)
=(20 x 32)
