1.What is motor bike c.c.?

2.How the priming is done in a centrifugal pumps?
As centrifugal pump is not a self priming pump,separate priming arrangement is required…generally,a separate axial pump is provided for this
purpose.The discharge v/v of the centrifugal pump is closed,and the inlet v/v is opened.The discharge v/v is opened only after the pump is
primed,that is filled with the liquid to be pumped.

3.What is the different between gate valve and globe valve?
Gate valve is non regulator means full close or full open positions only, while globe valve is regulator.

4.What is the purpose of o-ring, wearings in the centrifugal pumps?
O-ring : to prevent leakage between metal parts while allowing some movement between them wear ring : generally a softer material than the
parent material , employed to wear out quickly than the parent metal thereby avoiding loss of parent metal

5.what is the difference between Mitsui MAN b&w and Hitachi MAN b&w engines?
Design and system wise absolutely no difference. Only the license manfacturer is different. mitsui and Hitachi
kawasaki Diawoo are the different license holders for Man B&W for making the engines

6.How will we know, without opening anything,that an engine is 2S or 4S?
by the arrangement of the valves …in two stroke exhaust valve is situated at the top(i.e cylinder head) and there are scavenge ports at the
bottom in modern diesel engine…whereas in four stoke the exhaust and inlet is situated at the cylinder head.

7.How the power has taken from a large marine generator to the msb?
The 440v generated by the generator can be taken to the MSB via busbars. associated with preferential trips, overload protections

8.What is the meaning of code number which is given on bearing?
bearing number ia 6205z:
6 stands for the type of bearing , ie, deep groove ball bearing
2 standa for the the OD and width (thickness) of the bearing
05 stands for the ID of the bearing ie, 05 x 4= 20 mm bore;

9.In ship cranes, there is a provision of providing a conveyor for the cable. There is no provision of slip ring.How is it possible?
There r Slip ring arrangement in cranes onboard ships. the slip rings are present within the crane which is not seen from outside. the power
lines pass throough the centre of the crane through slip rings. The power line u see out side is only for grab which comes through the torsion
clutch. If there is no slip ring arrangement the crane cannot turn 360 degrees.

10.Which country level having below the means sea level?

head engine.

12.What is high temperature corrosion and what is center priming?
When material exposed to high temperature atmospehic situation like high level of oxygen presence, sulfer
presence and different type chemical presence cause matrial worsening . This type of material corrosion is
known as High temperature corrosion

13.What is specific fuel consumption and how fuel calculate?
generally it�s refer to the fuel consumtion rate, there are several deferent way to catlculate the specific fuel
consuption, such as volumetric method and flow method. but these methods can be taken only in lab. no possible do it on the sea.

14.How many types of ships?
Ships are divided into various types depending on their nature of service.
1. Cargo Ships (Bulk carriers, general cargo carriers,container vessels, oil tankers, chemical tankers, product tankers, gas carriers, Ro-Ro
ships). Depending on their sizes they are again classified as handymax, panamax,suezmax, afromax, vlcc, ulcc, vloc, vlgc, etc.
2. Passenger Ships
3. Serivce ships, such as cable laying submarines, off shore supply vessels, dp vessels etc

In transformer case Core occurs iron loss (Eddy Current & Hysteresis Loss) Or No Load Loss in Electric Transformer.

16.How many ports are there in India?
there are 12 major ports and 181 minor port in india

17. Why did you become interested in Marine Engineering?
A1 - A great way to make a living. Decent money, big chunks of time off, almost no commute. Somewhat of an adventure, interesting, challenging,
industrious are some words I like, which describe what I do.

18. Have you always wanted to be a Marine Engineer? or What made you become a marine engineer?
Not really. I have always like machinery or structures: drawing trucks and buildings were always my favourite pastime. LEGO were my favourite
toys. I always wanted to do something creative which would perform a function. I originally wanted to get into graphic arts and advertising,
but was lured away by the honesty of the sea and nature.

19. What do you like most about your job? or What is the best part of your job?
There are many aspects that I really like; but standing between two main engines while we are full away; the car size turbo-chargers whining,
the "rumble" shakes your very core; is very awe inspiring. Then to think, it's your responsibility!

20. What tasks does your specific job involve?
The list is very big. Too big in fact. The engineer is in charge of everything mechanical, electrical, or structural on the ship. The toilets
don't work, we go find the problems - and it's usually not pretty. From the computers to the crankshaft, air conditioning to refrigerators,
doors to windshield wipers, you name it, we must be able to make it work. I say that because we usually know how to fix, but as you can well
imagine, a person can't know it all. So basically, we must be knowledgeable enough to recognize a problem, then either fix it, make due, or
call in the specialists. We deal with it! out in the middle of the Atlantic, there's not many auto parts stores, and even less room for

21. Are you given a variety of projects to work on so that the job does not become boring? or Is it fun and exciting?
The nature of the Job always poses a large variety of challenges, everyday it's a different one. But boredom is definitely present on some
ships. For instance search and rescue ships which do allot of waiting and "sitting around", just like a fire dept. Some keep busy doing
"rabbits" -a personal project. One guy machined an entire miniature steam engine over a period of time. It is a bit mundane at times, but I
think it takes many year before you start getting bored, and that might be only if you are on the same ship, on the same run.

22. What kinds of challenges are you faced with while on the job? or What's the hardest thing you've had to do at your job?
The biggest challenge is getting along with people you have never met before and entrusting your life to them, like you would to your best
friend. Might seem a bit dramatic, but I think it's the most challenging task. You don't have the option to go to a warm home and "recharge
your batteries" if you've had a bad day. As for the rest of the tasks, you do what you can. Generally everyone on a ship is qualified to be
there and somewhat competent. You can work together to tackle big technical challenges, which goes to the top of the answer, getting along is
the biggest challenge.

23. What sort of risks do you deal with?
Life threatening risk are very present everywhere on a ship. The sea itself is not always picturesque, large machines moving fast, lots of fuel
to fuel fires, a multitude of chemicals, large quantity of electromagnetic waves: The ship in itself can be a very hazardous place to be, it is
always moving, even more so when you're doing work like commercial fishing, or replacing a ten ton buoy while at sea.

24. What physical condition must you be in?
The mental state is most crucial. But you're physical well being contributes a great deal as well. Most ships have work out rooms where you can
exercise. You have to be reasonably in good shape, this is to climb all those stairs. You need people that can, and will react in times of
emergencies -such as firefighting on board.

25. What does one need to do in order to succeed in Marine Engineering?
Good questions, when you find out, please let me know. I think its a matter of living in harmony, with people, machines and the environment.
You give respect, and hopefully you get it in return. Respect, in my opinion, is based on knowledge, the more you know the better decision you
can make, the better things go, the more respect you can command.

26. Is there an equal opportunity for women. Is it a popular career with women?
Not really. It is a worldwide occupation and allot of the seafarers in the modern merchant marine come from third world countries, where it is
not readily accepted to work for a woman. So allot of companies, I think, tend to shy away from crewing with a mix. This is changing, albeit
slowly, but changing.

27. I heard its tough to move up through the ranks, is Marine Engineering a serious career consideration for young Canadian?
Q11B - Did you experience any challenges in your career?
Q11C - Would you recommend this career to any student?
Q11D - Do you have any tips or advice on becoming a Marine Engineer?

28. Your questions, which seem to me to be as simple as "I'm I going to have a tough time feeding myself with dignity" the short answer is
perhaps. It is a very reasonable question since your candidate profession is not an easy choice. You would be better off getting a BSc from UBC
since it cost about as much, but you wont deal with isolation from civilization and probably wont have a tough time finding a job after your
final year because "people" are more familiar with what a University or College is.

29. The main reason for this answer is that our profession is an international one, and the realities is that Canada, and our standard of pay
is higher due to our high taxes and cost of living compared to other countries. As a result it will be hard for you, at first, to find a job
that you would be happy with internationally; and locally you will not be taken seriously because you haven't been in the field for 20 years.
That's just the way it is.

30. Having said that, I love my job. I love being around machinery, being around different people, and the ability to work in environments
people only fantasize about. It was tough at first, matching the needed ambition to complete the program, with the realities of the work, and
its availability, but things are getting better now. With self confidence that comes with experience, I believe my outlook is very bright in
Canada, and overseas. ...but it has taken me almost ten years !

31. Another words, if you are into instant gratification, marine engineering is not for you. You are getting into a field that requires a great
deal of long term investing towards something where the payday is, in monetary terms, generally not that impressive compared to other viable
avenues for young Canadians. There are allot of unknowns, upsets, tough times, but if you can keep focus on the big picture and persevere, you
will be able draw much satisfaction and pride that comes from working in environments that challenges most human faculties. You'll have to have
the confidence to tackle just about anything, and generally never be out of work. Some other benefits are - reasonably good pay, legislated
jobs opportunities (you'll always be needed), when you are not away working, your home for months at a time without having to take work with
you (unless you have a website), you can work anywhere in the world equally well. And you can branch out into numerous career alternatives to
sea going.

So its up to you to decide. If you play the lottery all the time hoping for a big payoff, then this career may not be for you. If you feel
gratified by displaying patience, dedication, and applying yourself to hard work, then you will appreciate this line of work. There is no easy
meals, but you'll never go hungry being a Marine Engineer in any part of the globe.

32. How much time do you spend on ships?
That depends on the company or the type of work. Generally, as an officer, you get one day off the ship for everyday worked, I usually don't
work for anything less than day for day. I onced worked 14 weeks away working on a ship, then I go home for 14 weeks, I've also worked  3
months on 2 months off, 2 weeks on 2 weeks off. 4 weeks on 4 week off is my favorite, but right now I work 6 weeks on 6 weeks off. 

33. Do you travel a lot for your job?
A ship by its very nature is always moving, not always to new places, but yes we travel allot. Signing on the ship and signing off the ship, on
the other hand, means we travel on planes, buses, trains, vans, cars, water taxis, walking and spending lots of time in airports. I consider
myself a seasoned traveller.

34. Do you design new equipment for ships?
Currently no. I work on the operational side of things onboard, so just maintaining the machines is a big enough job. We always have some
improvements to machines designs or processes but these are usually minor in nature.

35. How long have you been a Marine Engineer?
I started as a Marine Engineering Apprentice in 1996, achieved my first license level, a 4th Class Certificate of Competency (CoC) in 1999. I
achieved my second license level in 2002. There are four license levels.

36. What do you do on a daily basis? or What exactly do you do?
Right now, 2015, I work as Chief Engineer onboard a smaller Trailing Suction Hopper Dredge, a sort of big vacuum cleaner ship. My
responsibilities are extensive and I answer only to the Captain and the Superintendent ashore. I usually manage at least one other Engineer,
and together, we maintain the vessel with the aim of it always being available to perform its task.

In 2006, I worked on a large passenger ship in the capacity of Second Engineer. At any given point in the day there is two officers in charge
of the operations of the ship; one is on the Bridge - the Navigational Officer of the Watch (OOW) - one is in the Engine Room - the Engineering
Officer of the Watch (EOW) - I am the one in the engine room. I am in the control room of the ship (see picture), and monitor the engines and
just about every other system on the ship - from elevators function to fuel temperature, to water pressure for the showers. If there is any
problems, I rely on my experience and expertise to figure where the problem is and formulate a response. We have three Engineers in this
particular position and we are assisted by 1-3 other crew in the actual engine room. The OEW work 8 hours a day in the Control Room, and we
also have areas of responsibility in the engine room, where we spend an additional 3-4 hours maintaining "our" equipment. 

37. Where do you do your work? and How long did it take to get to your current place in your career?
Right now, in 2015, I work as a Chief Engineer the most senior engineer onboard, on smaller ships and large tugs. I am limited to the size of
ships (amount of horsepower - 4000hp) due to my lower Certificate of Competency (CoC). When I reach the First Class CoC, I will be able to be
CE on any ship, anywhere in the world. It took me about 9 years after my initial training to get to be in the position of CE.

In 2006, I work on the Rhapsody of the Seas (pictured), and large passenger cruise ship operating out of Galveston, Texas, in the Gulf of
Mexico. It had taken me about 6 years to get to this current position of responsibility.

38. How many years of college did you go through? and What college would you recommend to pursue a career in marine engineering? or What type
of education do you need to get to your current place in your career?
On the Training Page you will find most answers to these questions. As for me, I completed a four year Marine Engineering Apprenticeship which
means that I was hired by a company, then sent to a dedicated school, BCIT's Pacific Marine Campus in North Vancouver, where I had structured
formal training for about 4 months every year. Currently, its a little different, you sign up as a Cadet with the school and then you do your
practical time at sea with various companies. Check out the Training Page for further info. 

39. What was the best moment in your career?
There is no particular best moment I can remember. They're are so many, even more that I've forgotten until someone brings it up again over
beers. So there is no answers to this question. As most everyday, something new and sometimes, exciting, happens.

40. Did you ever come across something you couldn't do in your career?
As engineers, most people turn to us for answers and results, generally there is nothing we can't do; and those things are only restricted by
preconceived notions of what should be and accountants.

41. What college degree do most marine engineers have ?
Most Marine Engineers in Canada do not have a degree per se, if they work on a ship. There is a title of Marine Engineers that some people
carry, because they have gone to University, have taken Mechanical Engineering and specialized in marine structures such as wharves, oil rigs,
ship design, etc. Marine Engineers referred to in this website, are operational engineers for the most part. They have taken pretty much the
same basic courses as a Mechanical Engineer, but also have much more hands on courses as well. Ship's engineers do not specifically hold a
"Degree" but instead hold a "License" or "Certificate of Competency (CoC)" which is issued by high level government agency, and is recognized
internationally. The CoC is what allows persons to claim the title of Officer on a Ship. Some marine university offer "bridging" courses which
will enhance the Officer's training to achieve a "land recognized" University Degree.

Nowadays, new entrant in the field under the Cadet Program are granted a Bachelor of Science degree with the completion of the program.
However, this is still a gray area, and certainly worth investigating, as generally, a shore side position later in life, values these paper
things more than seagoing experience. 

42. What subjects in school would you need to excel at to become a marine engineer?
Physics, calculus, trigonometry, algebra, so on and so forth play a major role in the training, also sciences are pretty important, in

particular Chemistry. Anyone considering any engineering path should feel comfortable challenging these subjects.
