Construction and Working of Ships Refrigeration plant

Refrigeration plant Room

The refrigeration plants on merchant vessels play a vital part in carrying refrigerated cargo and provisions for the crew on board. In reefer ships, the temperature of the perishable or temperature sensitive cargo such as food, chemical, or liquefied gas, is controlled by the refrigeration plant of the ship. The same plant or a smaller […]



An Introduction to Ship’s Turbine Generator

steam_Turbine_Generator

Turbine generator is a popular source of clean power generation on ships as they don’t use any type of fuel i.e. heavy or diesel oil. Steam is used for power production in case of turbine generators. Steam is an easy, environmental friendly and cheap form of fuel on ships. For turbine generators, the steam comes […]



Understanding Stern Tube Arrangement on Ships

The propeller of the ship is fitted at the aft and attached to a crankshaft coming from the main engine. This is done so that the rotating motion of the Main Engine can be converted into thrust to propel the ship. The propeller shaft or tail shaft is supported by a bearing arrangement which acts […]



Learn About Fatal Bacteria that Grow in Ship’s Air-Con System

legionella bacteria in drain

It is a known fact that there are certain types of bacteria which flourish in the air conditioning system of a ship. These organisms or bacteria flourish or increase in number in stagnant water or in wet deposits of slime or sludge. If these bacteria multiply exponentially and are not removed then they spoil the […]



General Overview of Central Cooling System on Ships

Engine room coolers

The machineries fitted on board ships are designed to work with maximum efficiency and run for long running hours. The most common and maximum energy loss from machineries is in the form of heat energy. This loss of heat energy has to be reduced or carried away by a cooling media to avoid malfunctioning or […]



How Perishable Food Products are Transported Using Reefer Ship?

Refrigerated container ship

A reefer ship is a type of ship that is used for the purpose of carrying refrigerated cargo. Reefer ships are mainly used to transport spoilable goods. In today’s times refrigerated carriers play a very vital role in transporting food products that are necessary for daily use but face the threat of perishing very fast. […]

General Overview of Types of Pumps on Ship

positive-displacement-pump

A ship consists of various types of fluids moving inside different machinery and systems for the purpose of cooling, heating, lubrication, and as fuels. These liquids are circulated by different types of pumps, which can be independently driven by ship power supply or attached to the machinery itself. All the systems on board ship require […]



Understanding Diesel Engine Performance

On ship, it is important to check the performance of the engine from time to time so as to ascertain working condition and fault finding. In earlier days, the performance of diesel engine was taken manually, but with the advancement of technology, automatic monitoring systems are being used.



What is a Metering Pump On board a Ship?

metering-pumps

Metering pump, as the name suggests, is a type of pump which is used on ship to pump a precise volume of liquid. Metering pump can be adjusted to provide different flow rates. They are generally used when the precision of volume to be delivered is very important.



Bow Thrusters: Construction and Working

bow thruster

Bow thrusters are type of propellers, which are smaller in size and which help in better maneuverability of the ships at lower speeds. They are generally used for maneuvering the vessel near the coastal waters or while entering or leaving a port. Bow thrusters help in assisting tug boats in berthing the ship without wasting […]



Types of Heat Exchangers on a Ship

shell and tube type heat exchanger

Different types of heat exchangers are used on board a ship. The type of heat exchange used for a particular usage depends on the application and requirement. In this article we talk about different types of heat exchangers used on a ship.



Heat Exchangers on Ship Explained

Shell and Tube Heat Exchanger

Heat exchanger is an equipment which reduces the temperature of a medium by transferring temperature of that medium to another, when both the mediums are separated by a solid membrane or wall like structure. For efficient operation, the surface area of the wall which separates the two mediums is maximized, simultaneously minimizing the flow resistance […]
