Marine generator in Dubai UAE

One of the members of Marine Generators is that it works with 3000 minutes and it is also possible to reduce. It can also be a water cooler. The design of the generators is very small because they do not need to cool the air around them. Marine Land generators are used for sailing. These types of generators are very light, quiet and widely used. It is designed to be placed inside a soundproof capsule to protect against vibration and noise. When the generators are not installed properly, they do not show any action. The presence of generators is very necessary in recreational trips. In such a way that they are made so compact that they create the least space inside the ship.

Marine power generation

Marine power generation can be done on ships by diesel, shaft, or steam generators. For ports, shipyards, and inland structures, offshore power is used from the power source of onshore power plants. Unlike onshore, the ship's generator has neutral insulation points, meaning that its neutral is not attached to the hull. This is done to ensure that all the necessary machinery is up and running, even if there is a ground fault. Ships operating in international waters generally have a 3-phase DC power supply with a 440V neutral insulation system. Ships such as RORO, passengers, etc., which require a large amount of electricity, are installed with high voltage generators in the range of 3KV to 11KV. On land, the frequency of power supply can be 50 or 60 Hz, depending on the different parts of the world. On ships, 60 Hz is accepted as the standard method, which helps hundreds of engines on a ship run at higher speeds, even if they are smaller. The power supply, which is 440 volts, is reduced to 220 volts or 110 volts for lights and low-power signal equipment using a transformer. All of the ships' electrical equipment is similar to land but has been upgraded to withstand the harsh atmosphere of the sea and the moving ship to withstand the humid environment, high temperatures, salty and corrosive atmospheres, vibration, and so on.

Parts of the Marine Power System

Different parts of the marine power system

Electric ships on board can be divided into five specific systems:

• Generator system
• Main Switchboard System
• Emergency Switchboard System
• Distribution system
• Generator System

The generator system consists of an alternator and a driver for the alternator, which can be a diesel engine or a steam engine.

Many ships are equipped with a shaft generator, which uses the rotation of the ship's main engine to start the alternator and generate additional power.

The electricity generated by these offshore generators is transmitted to the main panel using a busbar. To connect power from the generators to these panels, there is no wiring inside the main and emergency electrical panels on the ships. All high voltage and high current systems are connected by a load bus.

• Main switch system

The main panel is considered the distribution center of the ship's electrical system, which receives electricity from the generator and distributes it to the electricity consumption throughout the ship. It provides power to all major ship machinery at 440 volts.

Part of the main panel is provided with a 220V power supply via a step-up transformer. This includes bridge equipment, navigation lights, radio communication equipment, and more. The power supply uses an auxiliary panel to charge the battery, which is used for emergency lights.

• Emergency switchboard system

An emergency generator must always be active after the main generator has failed. This emergency generator starts automatically and supplies power to the emergency switchboard.

All emergency equipment is connected to the emergency switchboard. The emergency switchboard is also divided into 440 volts and 220 volts and provides suitable machinery and equipment.

• Distribution system

The distribution system comes after the panel and consists of the following items

• Distribution boxes: These boxes are enclosed and made of metal to supply power to local parts of the ship's machinery.
• Engine start boxes: There are hundreds of engines that run several mechanical machines on a ship. Each group of engines is supplied with engine start boxes containing their "on and off" keys along with safety devices. Local meters for amps and temperature are installed on the start panel.
• Shore connection boxes: When the ship is in a port with emission control requirements or during the drying process when the ship's generator cannot operate, the shore force is used to start the ship's machinery. The beach panel is provided, which is usually located near the entrance of the residence or the shelter station to easily accept Kabul beach supply.

Lighting distribution board

The electrical lighting distribution panel provides lighting systems, housing systems, small heating appliances, circuits, and motors of 1/4 hp or less. Emergency shut-off panels: To protect machinery and ship personnel, various emergency shut-off panels are provided at various locations to shut down machinery and equipment in an emergency. The main purpose of installing a distribution system is to have an operational, warning, and safety console for individual or group machines. Power is supplied through circuit breakers to large auxiliary machines at high voltage. Miniature circuit breakers and circuit breakers are used for smaller power supplies.

The working principle of the offshore generator

The generator works on the principle that when a magnetic field changes around a conductor, a current is induced in the conductor. The generator consists of a fixed set of conductors wrapped in coils on an iron core. This is known as a stator. A rotating magnet called a rotor rotates inside the stator to generate a magnetic field. This field cuts through the conductor and creates an EMF or induced electromagnetic force because the mechanical input causes the rotor to rotate. The magnetic field is generated by induction (in a brushless alternator) and by a rotor coil that is energized by DC through sliding rings and brushes.

Marine power system safety

The safety of marine electrical systems includes protecting people from electric shock and damage to machinery due to electrical failure. For the safety of machines, depending on the size and power of the equipment, relays, circuit breakers or fuses can be used to prevent overcurrent or overheating of electrical equipment. Temperature gauges, engine speeds, direction indicators, ammeters, etc. are various devices that are used locally to monitor the performance of machines or electrical equipment and to understand the general health of machines.

Generators are engines that are used in all industries and include different types. It can be said that their main job is to convert combustible materials into electrical energy. The good thing about these engines is that they can ignite the material without the need for electricity. Of course, as we said, different types of these engines have different applications and facilities, which you should choose according to the conditions. For example, gas-burning diesels are used in some places. But the topic of this article is the marine diesel generator, which is one of the most important types of diesel generators. In the following, we will introduce you to how to buy, price, use and thousands of other things about this marine engine.

What is a marine generator?

As the name of this product suggests. It clearly tells us that its use is in sea and ship. This engine solves the ship's electrical problems and is considered a kind of electricity generator. No matter what vessel you have in mind, from commercial to pleasure vessels, everyone needs a marine diesel generator to prevent power outages and related problems.

marine generatore oil and gas

Marine diesel generators are a special and specialized category of power generators, products from this family are used in medium ships, pleasure ships and marine projects such as oil platforms and offshore equipment. These diesel generators can work in special marine conditions, and there are special problems due to weather conditions, such as high humidity, high temperature, corrosion of parts due to the presence of salt, etc. . . It has been solved in the best way.

In recreational boats and marine vessels, the electricity produced by this family of diesel generators is directly transferred to electric motors to provide propulsion power and all advanced navigation systems are also powered by this means. In marine, oil and offshore facilities, these equipments play their role as generators of electrical energy in the best way by complying with high standards. The engineering masterpiece of this family of diesel generators is cooling, which is sometimes done directly with sea water.
