What is inert gas in oil tanker?
What is Inert gas and Inert gas system? Inert gas system is the most important integrated system for oil tankers for safe operation of the ship. Inert gas is the gas that contains insufficient oxygen (normally less than 8 %) to suppress the combustion of flammable hydrocarbon gases.
How much does it cost to run an oil tanker?
The cost of operating the largest tankers, the Very Large Crude Carriers, is currently between $10,000 and $12,000 per day.
What is the requirement to the inert gas plant capacity?
Regulations and Requirements for I.G Blower The capacity of each blower must be 1.25 times the overall capacity of the cargo discharge system fitted onboard. This is to ensure that Inert Gas is always present in the cargo hold.
What is IG requirement as per Solas?
The International Convention for the Safety of Life at Sea (SOLAS 1974), as amended, requires that inert gas systems be capable of delivering inert gas with an oxygen content in the inert gas main of not more than 5% by volume.
What is purpose of inert gas?
Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air.
What is inert gas composition?
Inert gas means a gas or a mixture of gases, such as flue gas, containing insufficient oxygen to support the combustion of hydrocarbons. The oxygen content of the Inert Gas supplied to cargo tanks should be 5% or less.
How much money do oil tankers make?
Depending upon the size, capacity, and operational expenses, it is common for very-large crude carriers (VLCC) and ultra-large crude carriers (ULCC) to generate daily profits of $100,000 or more for their owners.
Why is inerting on oil tankers necessary?
The process of reducing the oxygen level in the cargo tank is called inerting. Oxygen content to less than 8% is required to be in the tanks containing flammable cargoes. And to be able to bring the cargo tank to that oxygen level, Inert gas containing less than 5% of oxygen is introduced in the cargo tank.
How do you calculate inert gas?
An inert gas is a gas that has extremely low reactivity with other substances. The noble gases—helium, argon, neon, xenon, krypton, radon, and element 118 (Uuo)—exist in their elemental form and are found in Group 18 of the periodic table.
How many types of inert gases are there?
When we refer to inert gases, we are usually referring to six primary ones, also called the noble gases. Meet the most common inert gases: helium (He), argon (Ar), neon (Ne), krypton (Kr), xenon (Xe), and radon (Rn). Another noble gas, element 118 (Uuo), does not occur naturally.

Is inert gas heavier than air?
There is little density difference between air and inert gas; inert gas from a combustion generator is slightly heavier than air while nitrogen is slightly lighter.
What is the concentration of inert gas in an oil tanker?
The concentration of inert gas is kept around 5% as a safety limit. The following components are used in a typical inert gas system in oil tankers: Exhaust gases source: inert gas source is taken from exhaust uptakes of boiler or main engine as contains flue gases in it.
What is inert gas tanker operation?
Tanker operation : Use of inert gas system. Inert gas (IG) piping Fitted on all tankers over 20,000 dwt and on all tankers fitted with crude oil washing (COW) systems. IG piping is usually large diameter low-pressure mild steel, with smaller diameter branch lines.
When is an inert gas plant required?
Check Flammability Diagram (Line GA) When a ship is in a gas-free condition before arrival at a loading port, the tanks must be inerted prior to loading. In order to maintain cargo tanks in a non-flammable condition, the inert gas plant will be required to:
What are the DWT requirements for fitting inert gas systems in tankers?
reduction in the oil tanker DWT requirements for fitting inert gas systems from 20,000 DWT to 8,000 DWT for tankers constructed on or after 1 January 2016 when carrying flammable cargoes. 4 Inert Gas Systems: The use of inert gas for the carriage of flammable oil cargoes
