Harvesting an abundance of oil and natural gas resources, the Middle East supplies nearly half of all exports to the global oil market. Middle Eastern countries Iran, Iraq, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates are all members of the Organization of the Petroleum Exporting Countries (OPEC), which pumps roughly 40% of the world's oil, with Saudi Arabia leading the pack for the greatest amount of output. OPEC's crude oil production was 28.7 million barrels per day in the first half of 2009.
Structural engineering is a field focusing on the analysis, design or evaluation of structures that are required to support or resist a load. This can include buildings, towers, bridges, dams, or structures such as oil rigs. Structural engineering ensures that throughout the stresses and pressures of the environment, structures will remain safe, stable and secure.
