Things to Consider When Choosing Marine Services

After going through the process of selecting and purchasing the boat of your choice, you have to invest time in choosing marine services suited to your budget. When making a purchase, the majority of people give priority to their budgets or the cost involved. But when choosing marine services, your budget should be secondary - it is recommended that you focus more on the quality of the services that you choose for your boat, as there are a number of them that you will require. They can secure your boat against any mishap or disaster.

Choosing marine services requires some research and planning as there is a wealth of choices for your boat. One of them - Marine Finance - helps you with the required financial support to purchase the boat of your dreams. You should do your best to be as meticulous as possible when choosing the right finance company for you. You must understand all of the terms and conditions of the deal before you sign the contract. The rate of interest charged, number of instalments, period of instalment and others are some important aspects that should be clearly understood before you go ahead.

Once you're in possession of your boat, it is advised that you get it insured. For this, you will require an insurance company that can cover all expenses, should any mishaps occur. €Expect the best, but be prepared for the worst€ is a good mantra to follow here; remember it when you are insuring your boat. With the right insurance policy, if anything goes wrong you'll have the cover to help you get through it.

Your boat requires maintenance. This can involve upgrading marine electronics and other equipment. Such tasks are quite technical and aren't always suitable to do yourself, without the right tools or experience. Moreover, the equipment can be expensive and if you don't hire a professional company, you could see yourself damaging delicate components.

You also need a supplier who can provide you with high quality sailing chandlers, clothing and other safety items. These include life jackets, flares, smoke signals, fire extinguishers and other necessities.

The task of choosing marine services can be difficult. You'd require a list of several companies to compare and choose the one that suits you. It's far more convenient to refer to a site that assists you with all the information and gives you a list of companies which provide various marine services.

Exports and imports are largely dependent on sea transport. There are lots of things that would be transported through water. For many people, airways seems to be the best option and yes it is. But it should not be forgotten that while airways being the fastest means of transportation, they have certain limits. One of the major limitations when it comes to the airways is that you can never send or get items that are too heavy. For an individual, this might not be an area of concern at all but for manufacturers it is. This is why sea transportation is the best of all. Infact, none of the automobile giants can survive in case they would not be able to export their vehicles to other parts of the globe. Their cars, trucks and bikes can be sent to other parts of the globe via ships. Now you can see that air transportation can never be used for exporting these against the pull of gravitation while they carry immense loads. While sea transportation is of such an importance, you can never deny the fact that the international marine services can play a crucial role.

What the marine services do

. Marine services can mean anything to do with the sea transportation. When you want the ships to roam on the sea and reach the right ports, you actually need services from various vendors and suppliers.

. The suppliers can be those who supply building materials for the ship, the tankers, the fuel tanks and everything that is used in a ship

. These services are vital because without them no ship can function in the right manner. In fact, those who supply maintenance goods for a ship do come under these services.

. The marine services can also offer services regarding labor management, consultancy services and relevant area.

How to choose marine services

. The first thing you need to do is to analyze your needs. The marine service you choose should be able to offer what you require. In case you need maintenance goods from the services you have chosen, but they offer only services that are related to ship building, then you cannot be satisfied.

. Always go for the services that conform to the rules and regulations of the government. Check for the authorization certifications and authenticity.

. Any service that does not include terms and conditions in the contract can be better avoided.

Generating Drinking Water on Ship - The Magic Machine

How is fresh water generated on a ship?  Is it possible to generate drinkable fresh water from sea water? 

Yes and for this purpose, a fresh water generator is used on a ship.This article will show the arrangement and working of a normal fresh water generator on a ship.

Introduction

Fresh water is of dire need on a ship. It is used for various purposes such as drinking, for preparing food, in laundry services and in many other day to day activities. In the past, people used to carry tons and tons of fresh water in barrels or in specially made tanks. This was because there were no other sources of fresh water once the ship was in sea, except rain, which was quite unpredictable.

Today in spite of means on board to generate fresh water,  ships carry tons and tons of fresh water in segregated fresh water tanks. But there are many other processes in which fresh water is used and as generally the fresh water tanks provided are not sufficient, the need arises to generate fresh water onboard. Fresh water is always in dearth also because it is very difficult to keep a check on the water usage by the crew members and also the usage cannot be avoidable as water is continuously required onboard ship.

Fresh water is generated on ship by a fresh water generator, also known as evaporator. The process by which fresh water is generated is known as distillation process. Sea water is converted into fresh water by evaporating and condensing the sea water. Evaporation of the sea water is either done by boiling or by flash process. This process enables the reduction of 32,000 parts per million in sea water to 1 to 2 parts in fresh water. Fresh water generators can be tube type or plate type.

Single stage fresh water generator

A fresh water generator consists of mainly two parts. A condenser and an evaporator. The boiling process is done either by a heating coil or by using the high temperature main engine jacket water. In some FWGs, heating is also done by superheated steam. Generally water is boiled at 100 degree Celsius, but in freshwater generator it is done at around 60-70 degree Celsius. For this purpose, educators or air ejectors are use. Eductors reduces the chamber’s pressure to such a point that water starts boiling at a temperature of 60-70 degrees Celsius. A flow meter is used to regulate the flow of sea water into the generator. The freshwater generated in the condenser is later collected by a distillate pump. A salinometer is used to check the salinity in the fresh water generated.

Working of the FWG

The hot jacket water from the diesel engine is passed through the evaporator’s heated nest. The sea water enters the evaporator through the flow meter and due to the low pressure of the chamber; it boils and gets converted to steam. Generally the feed of the seawater is kept half the stated quantity to facilitate adequate boiling of sea water. The steam then passes through a steam separator, in which the water particles in the steam are separated and collected.

The steam then enters the condenser, where it cools down to form fresh water. It is then removed from the condenser with the help of a distillate pump. The remainder sea water particles or the brine which gets collected at the bottom is drawn out with the help of an ejector pump.

Flash process- Increasing the efficiency

A liquid which is already having sensible amount of heat when introduced in a pressurized chamber, immediately gets converted to steam, i.e. in a flash, without the boiling process. Thus the phenomena can be used to acquire higher level of efficiency by controlling the exact pressure and temperature of the water, which will lead to higher energy efficiency.

This can be done by using a double stage fresh water generator.

A Description of Shell and Tube Heat Exchangers

Shell and tube heat exchangers are needed for high-pressure applications; they are durable products, which can withstand the demands of many working environments. Their design plays a large part in ashell and tube exchanger's ability to endure exceedingly-challenging situations.

Shell and tube heat exchangers are made from a series of tubes, which can be made of durable material such as fluoropolymers. Fluoropolymers are highly-durable plastics such as PTFE, FEP, and PFA. Fluoropolymers, like heat exchangers, have a place in a variety of industries such as the automotive, medical, and aeronautical.

In a exchanger's shell, one set of tubes contains fluid, which is either heated or cooled. Another set of tubes also contains liquid, which facilitates the heating or cooling of the primary set of tubes. A tube set is referred to as the tube bundle and can take on a variety of shapes depending on what is most conducive for the intended job.

Engineers of shell and tube heat exchangers need to consider several components of construction:

A smaller tube diameter enables the shell & tube exchanger to be economical and compact, yet a tiny diameter can facilitate malfunction and difficulty of cleaning. Larger tubing can be instituted to eradicate potential flow and cleaning problems. Engineers must factor cost, space, and the propensity of liquids to foul when constructing a heat exchanger.

Tube thickness is important to make sure there is room for corrosion; vibration existing in the product has resistance; and, the shell and tube exchanger can withstand pressure coming from both in and outside of its internal tubes.

Folding or wrinkling the inner tubes increases the flow of the liquid, which facilitates the transfer of heat, producing better performance from the exchanger.

Designers also consider the layout of the inner tubes. Tubes can be fashioned in a triangular, square, rotated square, or rotated triangular fashion. Particular, internal designs are conducive to specific jobs and the elimination of potential problems such as fouling of the liquid.

Shell and tube heat exchanger also host baffle components. Baffles serve several purposes such as holding the tube bundles in place; making sure tubes do not sag or vibrate; and, facilitating fluid flow.
