Working Principle of Fresh Water Generator on Board Ship

Fresh water generator(FWG) is one of the essential machineries on board ship, After-all a large amount of fresh water is utilized on ship every day. On board ship Fresh water is used for the most part by huge boilers having steam turbines as main propulsion or cargo pumps driven by turbines. They all in all record for 30+ Tons of fresh water every day separated from the day by day necessities of 10+ ton for crew consumption as drinking, cooking, washing,Tank cleaning and different utilities. Adequate consumable water might be taken up against the cargo load capacity in the port for satisfying crew and machinery necessity yet isn't prescribed to utilize shore water for boilers because of their low quality, so Fresh water generator is unavoidable on board ship.

But why do we need the FWG on board in first place?

In the middle of good old days people used to bring across lots of water in their ship. It was good however it expands the load on the ship and furthermore water lack issues were always there. Be that as it may, the nature of shore water will be extremely (too much) bad to be used in water tube boiler and filling (expansion) tanks. The storage space that could have been used for fresh water can as a result be used for fuel or added/more space for payload and products (that are bought and sold) when fresh water generator is installed on a ship. As you may know the first (or most important) concern for running a ship or any transportation business is to make money. Further more Boiler needs demineralized water to reduce overall scale development and corrosion issues. It is also normally used to build the general efficiency of the running machinery, mostly it uses the engine warmth/heat by Cooling The Hot Jacket Cooling Water At Around 85 Deg Celsius To 65 Deg Celsius.

Working Principal Of FWG?

Extremely important rule of all low weight freshwater generator is that, boiling point of water can be decreased by lessening the pressure of the air surrounding it. By keeping up a low pressure, water can be bubbled at low temperatures say 55 degree Celsius. The source of warmth for the fresh water generator could be waste heat rejected by generators and main engine jacket cooling water. This decrease In Saturation Temp lead to early vaporisation of water due to vacuum created within the chamber. It Is Created By The Help Of An Air Ejector, Which Extracts The Air From That compartment/chamber. An Air Ejector Works On Bernoulli's Rule and being used side by side with a brine ejector used to suck salt water from the chamber. The vacuum help disappear the water leaving behind the salt or salt water to be sucked by salt water ejector. It is then passed through the dimmister (A sort of punctured plate with very minute gaps) which traps any water or salt particle traveling through it. The evaporated water is then condensed together with the help of ocean water and after that tested for sality with the help of salino-meter.

Regulations Regarding Production of sea water on board ship:

1. Ship must be 12 nautical miles away from the nearest coastline to start the FWG.
2. Engine must be running at full ahead sea speed during start of FWG.
3. Ensure main engine parameters are normal.
4. Ship is not in congested water.
5. Ship is not maneuvering.
6. There is no oil/chemical spill reported in the visinity of the ship.

Safety Equipments on A Typical FWG:

1. Vacuum Breaker For Releasing Vacuum when we shut down the FWG.

2. Relief Valve For Releasing The Excess Pressure.

3. High Salinity Alarm: It Is Fitted To The Salinometer As It Measures Higher Salt Content In The Water Produced.

4. Temperature Gauge.

Starting Procedures for Fresh water generator:

• First we need to ensure that suction, discharge and overboard valves for ejector pumps are under open condition. Now once been checked, start the ejector pump.
• Close the vacuum breaker valve.
• Make Sure the S.W pressure at ejector (air) is not less than 3 bar. Now wait for 10-15 minutes to build vacuum in the generation chamber of fresh water generator. Wait until it shows more than 90% vacuum.
• Now open the sea water feed to the evaporator. Check for the sea water level in the shell through the sight glass and ensure it is at optimum level controlling feed through feed valve. Once the heating coils are fully submerged by the sea water open the J.C.W valves to the evaporator slowly.
• Purge out any air in the system by opening air vent at the top of the evaporator.
• Check for evaporation from the sight glass and then start the salinometer.
• Divert the outlet back to the feed water until the salinity is under the limit.
• When the salinity level is as per the desired or set value, open the discharge valve of distillate pump which sends the water to the fresh water holding tank through flow meter.
• Increase the evaporation rate and start the discharge pump. Check for the sytem to be stable.

Ship side valve Functions, Definitions and Specification

The valves on the side of the ship / Ship-side valves on the top refer to valves that are connected to the hull, without having anything to medium with the valve on the side of the ship. During the dry dock, the valves are checked by the dry dock personnel, while the work of the ship's engineers is to check the internal valves. For total seaworthiness of the ship, the ship side valves must always be in proper condition, They must have local as well as remote control operation which must be permanently connected. Pipes of the inlet and the outlet to the sea must be provided with valves or taps attached directly to the outer coating or to the plating’s of fabricated water boxes attached to the shell plating. These accessories must be fixed with threaded bolts equipped with hazelnuts.

Heads or bolts screwed into heavy steel pads built into the plating. Screw holes must not penetrate into the plating. Valves for the Ship side Side Applications must be installed so that the pipe section can be located directly inside the valve without removing the sealed integrity of the hull. Taps and accessories of the ship, when made of steel or other approved material with low resistance to corrosion, must be adequately protected against wastage/rusting. In the visual inspection, the valves should not show any sign of defects on their body, their internals and the spindle. The Thread and other parts must be in good condition, which ensures freedom of movement in the operating conditions. Ship side valves are made and tested in accordance with the rules and regulations of the classification society in the presence of an expert.

Markings on the Ship Side valve of the Ship: The following data are marked on each side of the valve.

a) Nominal size of the drill (eg NB 80);

(b)Nominal pressure according to section 1.4.

c) Test pressure

d) Brand / seal of the manufacturer.

e) Marker / Stamp of Classification Surveyor.

f) Flow direction

g) The weight of the valve to be marked.

h) Metallic tag numbers provided with the table.

Why are they so important?

In a Ship, all that has been installed has a purpose, besides the valves on the side of the ship is controlled and supervised by the classification society. Maritime organizations (classification society and flag state) know a series of incidents of local flooding machinery space installations and averaging two reports of floods received annually. The side flaps ensure the sealed integrity of the shell and the internal working sea tube from the sea. Operation of the valves allows maintenance of pipeline equipment. They are used to prevent the ingress of water into the compartments after a failure in a pipeline or equipment. Therefore, the valves must provide a watertight barrier when closed. In normal commercial vessels, the ship is docked dry and the ship's valves are inspected to meet classification society standards. This inspection confirms the condition of the valve and closes it when closed. For installations, such as mobile drilling units of fleets or ships of intervention, the inspection may be performed by dry dock times or repair in the port, however, permanently anchored facilities these inspections are carried out. They become more complicated as the right holder must be able to demonstrate that the valve is sufficiently leak-proof and in good condition. This can be combined by a close visual inspection and on-site testing. After repairing or installing a new valve, the dry dock repair shop usually provides a 5-year warranty on these valves. However, if the valves are damaged during the warranty period, the workshop will bear the cost of the diver's time and expenses.

How to do crude oil washing on ships in 10 easy steps

COW or Crude Oil Washing cleans cargo tanks with jets of high pressure oil when the ship is unloaded. The crude oil is pumped through the washing machines to the jets and serves as a cleaning agent which is then pumped to land with the load/Product Discharge. It has been found that crude oil is more reliable washing medium than water. The washing / dissolving effect results in heavy, waxy and asphaltic deposits on the sides and bottom of the Holding tank to convert back into the liquid so that they are easily discharge To the shore. The Crude Oil Washing (COW) techniques has several advantages over washing with water, using Cow as the washing medium reduces the Sludge deposition, thereby reduces the discharge (Stripping) time and increasing the load/cargo flow. There low deposition of mud at the bottom of the tank which reduces Ship constant and so increase its dead weight. On the other hand washing with water takes more time due to more deposition of mud at the bottom. They not only cause delay in washing but also release hydrocarbon gases which becomes a challenge to gas free the tank. There are three essential prerequisites for the washing of petroleum product:

A fully functional inert gas system for maintaining the tank atmosphere in an inert state during the whole wash cycle.
Fixed Piping Lines for Tank washing system
Means to ensure that the bottom of the tank is clean and dry at the end of the operation.

The vessel must be equipped with an inert gas system which can function properly and produce Inert Gas with a maximum oxygen content of 5%. This should be maintained during the COW to ensure that the oxygen content does not exceed this value. No COW operation to be performed if the Inert Gas installation of the ship is not working properly and the oxygen content is not within the desired limit. The oxygen content must not exceed 8% by volume. The IG pressure in the tank must not be less than 200 mm. wg. The vessel to be washed with oil must be equipped with a fixed tank wash system connected by permanent lines to the main load venting system or by separate laundry lines of the loading system. The crude oil washing of discharging tanks takes place in a single step or in several stages during the discharge of the charge.

One Step Washing:

As soon as the tank is almost emptied , Washing starts and the tank is dried under pressure during the last washing step using stripping. The machine adjusts to the vertical angle from 0 to 140 degrees. Since single-stage washing is performed only during the last tank discharge stage, it is necessary to use the ship's instructor to remove the pump or reduce the speed of the charge pump so that the vacuum pump is effective. This method is generally useful between discharges at two terminals or between ignition operations.

Multi-stage washing

This involves washing the interior areas of the tank in stages as the load is pumped out of the tank. The revolutions of the charge pump are not reduced. Depending on the back pressure in the distributor of the vessel, this process results in a very small time loss during the bulk discharge of the tank. The wax and sediment collected in the spacers and other structural elements above the bottom of the tank are removed and pumped with the load to the ground. Any wax or sediment on the underside of the tank remains as long as the soil is not washed and stripped as a separate step. This increases the total discharge time, but is required for sludge control.


The machines are pre-set in the first stage at a vertical angle of 120 ° to 60 °. In the second step, when the loading level is about two thirds of the tank depth, it is set at a vertical angle of 70 ° to 30 ° and during the third stage when it is set to about 1 meter of the residual charge in the tank to 40 ° to 0 ° is. Each step is superimposed by approximately 10 ° in the preceding step, and the cycle is normally 11/2, ie, in the first step, for example, the nozzle moves in the horizontal plane by slowly changing its angle from top to bottom or from 120 * to 60 * from top to bottom, or from 60 * to 120 *, and from top to bottom, or from 120 * to 60 *

The regulation requires that the cow jets cover at least 90% of the horizontal surface area of the floors, rods and structural elements and at least 85% of the vertical direct zone. Shaded areas should be covered with splashes or deformations.

List of oil washing equipment controls
In the case of unloading of raw materials, the master must notify the competent authority and the terminal (or any other ship in transit to the ship), at least 24 hours in advance or at the time of compliance with the regulations. The washing of crude oil should only be approved once each step of the COW operation must be specified in the oil wash operation plan. There must be an operational checklist for the use of the crew at each port of discharge. This includes the control and calibration of all instruments to be used during the operation of the cow.

Pre-Arrival Checks at Discharge Ports

1. Notification to the terminal of the operation of the cow.
2. Is the oxygen analyzer successfully tested and operated?
3. Is the water heater and the flushing system of the motor compartment insulated?
4. All Valves Marked washing is isolated from that of engine room pipe line.
5. Are all V/vs closed for stationary tank washing machines?
6. Are the tanks cleaning lines under pressure and tested for leakage?
7. Do you make portable drives for the M/C quick tank sink that will be tested?
8. Have gauges on the top line relief manifold has to be verified.
9. Should the trimming system control equipment cheked?
10. Has the communication system been reviewed and tested?
11. Has the organizational plan been set up and defined the duties and responsibilities of crew?

 Checklist before cow Operation

1. All checks and conditions are in order prior to arrival.
2. Unloading/operating the raw oil wash has been discussed with ship and shore staff and is readily available the agreed plan for a simple reference?
3. Was the communication link between the control and control stations and the monitoring/shore station repaired and functioning properly?
5. Has the fixed and portable oxygen analyzer been verified and calibrated?
6. Is the inert gas generator functioning properly and the oxygen content of the inert gas is delivered below 5% of the volume?
7. Is the oxygen of the tank washed about below 8% in volume?
8. Is the gas pressure is positive for the entire cargo tank?
9. Keep person responsible for checking all the lines for leaks as soon as the operation starts?
10. Are stationary machines for the necessary washing and portable motor units, if installed, mounted and repaired?
11. Have valves and lines both in pump-room and deck been checked?

Checklist-During the operation of the cow

1. Is the quality of the inert gases supplied often controlled and recorded?
2. Are all deck and machine lines often tested for leaks?
3. Is the current tank only available for COW?
4. Is the pressure on the appropriate tank wash line indicated?
5. Is the processing time of the tank disk indicated?
6. Is the washing machine, which works with the propeller groups, often properly controlled and working?
7. is a responsible person constantly stationed on the bridge?
8. Will trim be satisfactory when bottom washing is in progress as specified in the COW manual?
9. Is the level in the reservoir for tank washing often checked to avoid overflow?
The cow should be abandoned immediately if:There is an error in the inert gas system or oxygen exceeds the permissible limit, or The pressure in the tank falls below the air pressure or a minimum required (usually 200 mm water gauge).

D Checklist-After cow operation

1. Are all the valves between the discharge and the washing line of the tank closed?
2. Has the laundry been drained of oil from the crude tank?
3. Are all valves closed to the washing machine?
4. Are the cargo pumps, tanks and pipes properly drained as indicated?

Sludge and sediment control

Under certain circumstances, substantial sludge may also form in the containers, even in the case of crude oils which are not normally associated with such accumulations. Studies of incidents of large sludge accumulation show that there are specific critical temperatures at which crude oil begins to precipitate hydrocarbon species that form mud. This temperature, cloud point, is the temperature at which the crude waxes change from their liquid phase to suspended, nearly solid particles with associated oil components. These particles separated by phases are installed at the bottom of the reservoir and form mud. Sludge from paraffinic crude oil, once formed, is extremely difficult to return to a liquid phase by heating alone. Even an effective COVER program, which eliminates them from boats, has only managed to solve the problem in shore-based containers.

Electrostatic risks
The oil used for COWing must be free of suspended water to minimize the formation of electrostatic charges by high pressure jets. To ensure that the oil supply to the VAE is dry, the cargo tank to be used must be discharged to the ground before the start of the COW. At least one meter of load must be discharged. This removes all bottoms from the tank before the mold starts. VACA procedures that remove the flushing fluid from the discharge current or use a sliding container that is then filled with clean oil will avoid this problem.

How inert gas is produced on board ship?

The Inert gas is produced in the IGG by the combustion of fuel with air. Marine diesel oil (MDO) or MGO is drawn from the storage tank and pumped through a filter to the main burners. A blower delivers the air necessary for combustion.
Oil and air is mixed in the correct proportion in an air-atomizing burner, which is ignited by the pilot burner. The fuel-air ratio and the oxygen content of the IG can be regulated by a valve in the fuel supply line to the main burner. Purple-blue to rose-purple flame indicates good combustion whereas yellow flame means too much fuel oil or too low delivery air pressure causing low atomizing pressure and risk of soot formation.

The inert gas thus generated consists of mainly Nitrogen and carbon dioxide. It is first cooled in the combustion chamber by means of a sea water jacket, which surrounds the combustion chamber. The gas then comes in direct contact with a water spray. The resultant IG comprises of:

Oxygen  :            2% by volume
Carbon dioxide: 13% by volume
Nitrogen   :        85% by volume

Due to perfect combustion, there is a complete absence of soot. The temperature of the gas leaving the generator is about 5-10* above the cooling water temperature.
During the operation, should there be a reduction in demand for the IG, the excess gas is vented to the atmosphere. The operation is continuously monitored for flame, water or control air failure and excessive cooling water level. Should any emergency condition arise, the IGG automatically shuts off and sounds an audible alarm.
This is a costly installation, which is usually found in product or chemical tanker. With some clean cargo tainting could be a problem, if flue gas from boiler is used.

Chemical tankers & Product tankers are normally FRAMO tankers hence IGG is fitted on these ships, secondly the quality of IG plays a very important role in maintaining the quality of chemicals being transported.
Conventional tankers with turbine driven COP will always have a large water tube boiler and thus Inert gas on these ships will be produced from boiler flue gas. Boiler will be used continuously during cargo discharge for running the cargo oil pump turbines (COPT).
On Framo tankers, the cargo discharge system consists of each cargo tank having a fixed submersible cargo pump, this pump is coupled to a hydraulic motor. The hydraulic motor is driven by high pressure hydraulic oil (220 bar), this high pressure hydraulic oil is delivered by hydraulic power-packs located in the engine room, these power packs are normally driven by diesel engines. Thus these ships use an IGG for production of inert gas. They do not have large boilers as no turbines are present, hence IG from boiler uptake is not possible.
Carbon Molecular Sieve type Nitrogen Generator

The molecular sieve nitrogen generating plant is usually installed on ships such as chemical carriers where oxygen critical cargoes may be carried and purity of the inert gas is of utmost importance.
The system uses the pressure swing absorption method using a carbon molecular sieve which has the unique property of absorbing oxygen in preference to and at a faster rate than nitrogen. When air passes through the molecular sieve, oxygen is absorbed. Nitrogen gets across and is collected. However the sieve gets saturated with oxygen after sometime and needs to be changed over.
The system uses two vessels packed with the carbon molecular sieve. The vessels are alternatively on line or in the process of regeneration. As one reaches saturation, the system switches to the second. Change over time is appox. 1 minute.

The oxygen from the saturated sieve is removed by applying a reduced pressure to the vessel and then venting to the atmosphere. The nitrogen gas thus generated is fed to a buffer vessel from where it is distributed to the inert gas line. The purity of the nitrogen depends on the flow rate and can be as high as 99.5%. The lower the flow rate, the higher the purity and vice versa.

Hard to get a job as TME or Deck Cadet ? | Getting started on job hunt

For the past few years, I have been noticing how difficult it has been to get a job as trainee marine engineer or deck cadet on ship after completing marine engineering or nautical science course even from a well recognised maritime institute. The main reason behind this would be the approval of so many substandard institutions by the government in recent years, because of which the number of students graduating every year is far more than the number of job openings that we have. Along with this, a lot of job agents, mostly fraud ones have come up offering jobs in known and unknown companies taking a huge amount of money and you would wonder that the average agent fee they are charging has been above 3.5 to 4 lakh INR for a normal company and 5 to 6 lakh INR for a well known highly paying company which is one third of actual engineering course fee itself. The funniest part in fact is that the agents get only 10 to 15 % of the fee and the rest goes to the people who are sitting on top of crewing department in these companies, even the best shipping companies I would say.Though it is rare that the companies take freshers from outside without reference, there are few companies that do recruit cadets on regular or non-regular basis. Some of them are below.

1. Shipping Corporation of India, SCI ( www.shipindia.com )

2. Wallem Ship management ( www.wallem.com )

3. Nortrans Maritime ( www.nortrans.com )

4. United Ocean Ship management ( www.uosm.com )

5. Seastar Ship management ( https://www.seastargrp.com/shipping )

6. V-Ships ( www.vships.com )

Links of mumbai located companies are below ( in case if you guys want to do job hunt ).

Shipping Companies in Andheri West - https://www.justdial.com/Mumbai/Shipping-Companies-in-Andheri-West/nct-10432101

Shipping Companies in Andheri East -

Shipping Companies in CBD Belapur -
https://www.justdial.com/Mumbai/Shipping-Companies-in-Cbd-Belapur/nct-10432101

I wouldn't say not to approach agents for a job because the fact is that 70% percentage of the students graduating from most of the maritime colleges don't get their placement and to get one, they should either have very good contacts in shipping or they should look for a genuine agent. Over the years, I have seen many trainee engineers and deck cadets coming to mumbai to find an agent, some of them get a job after long waiting, some of them don't and the rest of them get cheated by fraud recruiters. If you are a fresher and you are paying money to an agent, make sure the company they recruit you to is approved by DG Shipping of India and has an RPSL ( Recruitment & Placement Services License ) number which is not expired. 

Never ever pay the agent before your contract letter is signed !!!!

How is Marine Engineering as a career? | Explained

Transport and transportation are the backbone of modern global economic outlooks and global prosperity. Ships are what the world traffic is based on, which  account for 90% of the total movement of fresh products in the world than any other transport accounts.  It Transmits solutions, food, medical care and living conditions, chemicals, oil, fuel and other loads that are necessary to ensure the viability of each country. Therefore, as an important aspect, a marine engineer plays an important role in international transportation of goods around the world in some form or another in shore, oil rigs, offshore and shipbuilding.

The Capital associated drive the demand in international trade and shipping, So the ships should be advanced and technically sophisticated. The ships are to be maintained with massive engines and factories of electricity for the propulsion and auxiliary on the ship with a specific end goal to Maintain Seaworthiness. All technical aspects of the Ship holds extreme operational efficiency and so  considered and maintained by ship engineers.

A naval engineer is a lucrative job offer. A marine engineer acquires considerable knowledge and the ability to work under pressure and difficult conditions at sea. It is self-confident research all aspects of the machines to work. The first and most important reason is the danger contains. Work on the vessel is carried out in coastal offices, as well as power stations, shipyards, etc. In all cases, the coast of jobs, they are not paying as much as they can on boats considering the fact that an office on the coast is the same Hard conditions, a boat facing.

Marine engineers are the true saints with jack of all trades and an ace of diesel engines. Working in  the transport company makes them meet and see many universal things as well as exposure to the outside world. They know how the configurations of the nations of the world are the same. They know how to get at different places in the world "Things Done". They look like the experts end their work quietly making the wheels of the global economic race.

There are usually six engineers on a Ship *:

Junior Engineer - Unlicensed Member Engineering Department, which helps senior engineers.

4th. Official supervision responsible engineer for air compressors, fuel oil cleaners and lubrication and auxiliary diesel generators.

Electrical Officer- Shares Equal Rank with Fourth Engineer, responsible for Electrical Aspects of Ship.

3rd. Engineer watch, responsible for the production of Fresh water, Sewage channel discharge, maintenance equipments, Air Conditioning, Refrigeration and various pumps.

2nd. Engineer responsible for the administration, responsible for the main motor and drive, boiler aux and steam generator. The Incharge of team management on ship, steering mechanism, ship cranes and engines, rescue boats and engines

Overall, chief engineer - by the actions of the department motors equal with the captain.

* This is based on the classification system of British engineers on the ship.

Economic Outlook Marine Engineer and Scopes:

According to the US Government’s Bureau of Labor Statistics, Marine Engineers and Naval Architects earn an average annual salary of $84,850. However, the top 10% of the career field pulls in a healthy $145,790 annually.

The need for marine engineers was expected to grow by 9% from 2014-2024, according to the U.S. Bureau of Labor Statistics (BLS). The demand for new Marine engineers will rise due to a no of factors, First many ships are to be modified and installed with latest machineries to comply with latest regulations drawn by IMO and flag states. Second, As the demand for oil is growing world wide, more and more shipment are chartered and so new ships will be bought to cope up with the rise in demand with additional crews and marine engineers hired to work on them. Third, there seems to be a sudden boom in the shipping field just after 10-15 years as the years of looms are to be end very soon, Leading to sudden high demands for fresh and experienced marine engineers.

The level of financial stability is high start from the beginning which allows great deal of money to spent and for savings. There is a whole new world out there to be explored and to feel and see the glim's of the world you watch or read in T.V and magazines.

Work of Marine engineers (Expectation vs Reality):

When i first join this field i had many expectations, crazy one to be precise, like i will be traveling all across the world have some very great times at ports, have a office inside the ship not much work, all time party, Lots of alcohol etc..etc.
            If you too have such ideas in mind thats totally rubbish. All I can tell you that there are quite less port time you get as the time for loading and discharging are reducing day by day, There no alcohol policy in many of the ships these days with lots and lots of hard work and maintenance to do just to catch up with the daily planed schedules.

Followings are the real work space and work of the marine engineers on board ship in reality:

Engine Room

The main propulsion plant, diesel generator boilers for power generation to produce steam, the fresh water generator, the electrical equipment to the various motors and are in the engine room.
The atmosphere is usually hot and loud in the engine room. The temperature can even rise up to 55 degrees Celsius. Marine engineers perform regular inspections and repairs and maintenance work at the time. Ensure a safe operation of all equipment and follow all safety precautions to prevent marine pollution complies with the strict international regulations.

ECR(Engine Control Room)

All parameters, conditions and the propulsion of the main motor and the connection between the bridge are remote from the engine control room is controlled. Engineers are placed on the watch during the peak day of unmanned ships. In the old ships are usually monitored 24 hours a day rotation 4 hours.

Life on board a Ship

In addition to machine operation, maintenance supervision and regular maintenance, ship engineers spend a lot of time on leisure activities such as sports, games, entertainment and fitness activities. The food served on board is good and healthy, there is plenty of time to relax. Watch the sunset, music, photography, fishing and sports are important activities that are usually done on a boat.

Sea- Merchant naval ship, the time is very important. The load must arrive on time. Communication between the bridge and the space navigation motor control is required to maneuver the ship. Total control with the engineers stopped when a fault monitoring device occurs in bridge. Steering device testing is necessary for the navigation of a ship. The machine must be addressed as required. Always observed always essential solution for the drive safely. The climate is another thing that affects the ship at sea, which affects people on board must be able to withstand tough conditions. All environmental policy and regulations oil pollution must be strictly adhered to. While the ship at sea, profound experience, practical skill and lower attachment is needed to overcome all unwanted situations. The ability to make decisions and take action is required in every ship engineer. The risk of fire and explosion is always high to minimize these risks, we must be well trained and competent.

Ship in harbor

While the ship is in the port, repairs, maintenance and additional checks are carried out by the port authorities. Dock can be at the port, which requires safety. Inventory store Engines and spare parts will be ordered as required. The charging process should go smoothly and the energy production is observed every time.

Apart from this, there is ample time to leave the port and explore new places. You can go and send entertainment. Seafarers can go the country of origin Seaman Club or hotels to sign up to its flight the ship.

Close of Contract

After the end of his contract, returns to his country of origin leaves the earth. There are few companies that pay wages a year. However, wages are usually high compared to other technical disciples on Earth. Full salary savings for us because the boat house and home for the return of the boat are born by the company. They are entitled to be on board in safety and are also exempt from the tax obligations. This point is very important because he / she stays away from home and the family for extended periods of a few weeks to several months.

Class Competency tests

Marine engineers must pass suitability tests to grow at a higher rank. These tests are carried out by the Ministry of Shipping and take most of the time you spend on Earth. Apart from this, they must be regularly updated with security and updating courses.
