Crude oil is less dense than water. This is apparent after oil tanker accidents where the oil floats on the surface of the ocean. http://img.timeinc.net/time/photoessays/2007/skorea_spill/skorea_spill_01.jpg In fact, most oil is less dense than water (ever seen salad dressing that's separated? It's split into it's oil and water components!)
Crude oil is oil got from directly extracting process. you can use an oil extracting machine such as screw oil press or hydraulic oil press which are common oil extracting machines used for this.
because crude oil and gas are cleaner to burn
crude oil
Yes it is
An oil tanker would be carrying crude oil, not refined product. So the answer would be zero.
Tanker takes over
Oil tankers vary in size by a huge margin, from a few thousand tonnes DWT to 500,000 tonnes DWT. The density of crude oil also varies, averaging around 0.7 kgs per litre. There are 159 ltrs (apprx) per barrel. From this you can calculate how much each type can carry.
A Oil Tanker can carry up to 550,000 DWT '' Dead Weight Tons'' DelSol_Racer.
Usually they carry crude oil. In general they are built to carry bulk liquids
MR oil tanker actually refers to Medium Range Product Tanker which is between 42,000 dwt to 59,999 dwt. There are two categories of ships in the oil tanker industry. First are the Product tankers which transport refined petroleum products like gasoline, diesel, naphtha, aviation fuel, etc. Second are the Crude carriers which transport unrefined crude oil.

Pipelines are the safest way to transport fuel, oil, etc.
get it from places like Africa who send it to UK in tanker ships along the sea
