Description

Oil loading compartment suitable for cargo ship loading

Technical Field

The invention relates to the technical field of petroleum containers, in particular to a petroleum loading compartment suitable for loading a cargo ship.

Background

The global economy relies on oil for operation and, of course, these vessels for crude oil transportation worldwide. The ship for transporting liquid bulk cargo is a cargo ship for transporting various oils, and in addition to transporting petroleum, the ship ships ship petroleum product oil, various animal and vegetable oils and the like. Various petroleum cargo vessels, which are sailing at sea, can be roughly divided into two categories: crude oil tankers, which are often large vessels such as VLCCs or ULCCs, are used to transport crude oil throughout various locations, primarily unrefined processed crude oil from the source to the refinery. Product oil tankers, which are primarily intended for the transport of product oil, are smaller in size than crude oil tankers.

In view of the dangers of such vessels carrying cargo, seaman must be careful when working on tankers, which require more and more extensive safety training than container ships and bulk carriers. Cargo carried by each type of tanker is not inherently or dangerously dangerous, but they all contain various risk factors.

It goes without saying that the seaman working on any type of tanker, whether VLCC or ULCC, or small tankers, must know and be aware of the various risks involved with the tanker, and then which risk factors are those on the tanker.

1. Cargo: cargo carried on tankers is flammable because most of them release certain types of gases that form a combustible mixture of hydrocarbons, including 1-10% hydrocarbon gas.

2. Smoking although most shipping companies prohibit smoking on board, some tanker fires have occurred in the past due to smoking in areas where smoke and fire are prohibited. The seaman must always comply with the regulations concerning smoking and can only smoke in designated smoking areas. Do not carry cigarettes, matches or lighters to the deck.

3. Static electricity, which is static electricity in tanks on tankers, may be less dangerous because the charge is transferred to the hull by the earth protection. However, if an electrical charge is present in the tank, the objects brought into the golden house may produce sparks, resulting in an explosion. Therefore, before any golden house object, metal tool or probe meter is used in the tank, it is necessary to check the earth protection device.

4. Steam: steam should not be injected into the chamber or ductwork containing the flammable mixture because the high velocity moving water droplets in the steam stream may become charged as they pass through the nozzles and create a charged mist.

5. Carbon dioxide CO2 containing fire suppression systems suppress fires by spraying carbon dioxide at high velocity. It rapidly evaporates and then cools and forms solid carbon dioxide particles, which may become charged.

Therefore, the key point of safely transporting the oil on the sea is to ensure that the oil loaded in the oil storage bin in the cargo ship is in a relatively stable and safe environment and guide and eliminate static electricity generated by friction and collision of the oil with the tank wall in the transportation process as much as possible.
