Inert gas is produced on board crude oil carriers (above 8,000 tonnes)(from Jan 1, 2016) by using either a flue gas system or by burning kerosene in a dedicated inert gas generator. The inert gas system is used to prevent the atmosphere in cargo tanks or bunkers from coming into the explosive range.

Fig 1: Inert gas generator Boiler exhaust gas inerting system A system much used on tankers where boiler exhaust gases are cleaned and inerted is shown in Figure 2 below. The exhaust gas is cleaned in a scrubbing tower, dried and filtered before being passed to the deck mains for distribution.
Inert Gas systems is mandatory technology for oil and chemical tankers with existing vessels > 20,000 tonnes and for new vessels > 8,000 tonnes. Installing an inert gas system is equal to essential protection of your vessel and people’s safety.
use onboard tankers intended to carry both crude oil and refined products, and combine into one compact unit where quality is the number one priority. The Wärtsilä Moss Mult-Inert™ system can run as an inert gas generator or, when the boilers are in use, as a flue gas system. They are designed based on compact modules,
Cargo discharging operation in oil tankers Oil cargo discharge operation involves various safety factors to be taken into consideration. Following are the most common elements and check items to be followed. The procedures explained here are only indicative, not exhaustive in nature and one must always be guided by the practices of good seamanship.
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. Inert gas isolating valve:It serve as the supply valve from uptake to the rest of the system isolating both the systems when not in use.

To avoid the presence of an explosive mixture in the cargo tanks above the oil an inert gas is installed to provide a slight overpressure gas blanket at the top of the cargo tanks and slop tanks. The inert gas system is designed to comply with the SOLAS 1974/1978 regulations for tankers (International Maritime Organization, 1974).
Deck seal is a safety device fitted on oil tankers to prevent explosive hydrocarbon vapours to ... The purpose of the deck water seal is to prevent feedback of hydrocarbon gases from the cargo tanks via the inert gas deck main to the engine room and boiler uptake. ... Regulation 62 requires that the inert gas system is equipped with two non ...
The normal method is to fill these tanks with inert (non-explosive) gas from the ship's boiler flue: it is cleaned and then pumped into the empty tanks, or into the spaces left above the oil in loaded tanks. An inert gas system is required on all new tankers and most existing tankers of 20,000 dwt and above. Equipment duplication
Boiler Fuel Oil Systems.This type of heater is delivered as a whole, and is installed on site, it only needs to connect thermal gas(oil) piping and electricity to start operation. The heater has four heating areas: furnace radiation heating area, the first convection tube bundle heating area, the second convection tube bundle heating area and ...

Types of boiler burners: Boiler burners are the central element of effective combustion system design which includes fuel preparation, air fuel distribution, furnace design and combustion control. A burner is a mechanical device that supplies required amount of fuel and air and creates a condition of rapid mixing and produce flame.
In this system, the oil flows freely into the aft most tanks when the interconnecting gate valves are opened. Main suction bellmouths in a full free flow tanker will only be provided in the aft tanks. However, each tank is generally provided with a small stripping line. This system has the distinct advantage of having lesser and less ...
