The costs of fuel keep rising up on a daily basis but the people do not know where the oil comes from. The oil is used in a number of ways and the lack of it in a day will make business to stop and people to be scattered all over with no form of direction to follow. This is the major factor that companies the whole world. Just like food, one cannot leave without oil and even though we do not need to handle it ourselves it is used in the things that we do or use.

However, a lot of people might probably no idea where crude oil sources could be, apart from digging deep into land underground. Most of the oil is drilled in lots of places but most of it is drilled below the waters. Such process is commonly referred as Offshore Drilling . It is a very hard process to get to the core root of the sea but with lots of equipment and skill, the oil will be extracted. Getting to the seas seems to be the real hard but there are vessels called rigs that enable one to go to the sea and drill the oil out.

There are a number of factors that the company needs to keep in mind when they are choosing the required vessel. It needs to drill really deep to get the oil bed effectively. Offshore Drilling rigs need to be able to dig thru deep into the earth layer to reach oil reserve layer, unless the position of the oil us just beneath the surface, which is rarely be the case.

To get started, the company needs to analyst and find out the most probable location of the oil. This will then enable the company to get the best suitable drilling rig that is fit for the job. These days, most of the rigs have been built with sufficient space with accommodation for needed manpower on the rig itself.

Further, with advancing technology, oil rig builders have been able to build up gigantic rigs that are able to withstand the tough weather challenges, and rigs are able to be station permanently to drill out the oils. Crude Oil storage and transportation vessels too are to be well equipped with all the requirements to fit for the job. The oil is abstract and carefully kept in the storage and transportation vessel where it will not mix with other substances. A lot of care has to be taken care of when it comes to crude oil transportation , as we are well aware that oil leakage cause a slot of pollution in the water and this will kill the aquatic life.

For some location that are considered as near to the coast , they no longer require making countless trips to and from the sea. Refineries are built at coast area with oil pipe that transport their oil in its natural form right from drilling rig.
