O&G reserves in the South China Sea: Tempers Flaring
Geopolitical location, an abundance of fish and huge O&G reservoirs make the South China Sea (SCS) particularly attractive to the countries that all lay claim to parts of it, such as China, Taiwan, the Philippines, Malaysia, Brunei, Vietnam, Indonesia, Singapore, Thailand and Cambodia. While the Chinese National Offshore Oil Company (CNOOC) estimates the SCS holds around 125 billion barrels of oil and 500 trillion cubic feet of natural gas in uncorked reserves, the U.S. Energy Information Administration (EIA) estimates the SCS contains only approximately 11 billion barrels of oil and 190 trillion cubic feet of natural gas in proven and probable reserves, although the EIA admits this figure could increase pending geological surveys of peripheral locations.
Pelamis P2 – How the Wave Energy Converter Operates
The Pelamis P2 is the second-generation Pelamis Wave Energy machine and includes a number of significant design improvements. The P2 design has been sold to utility customers E.ON and ScottishPower Renewables and are currently being tested for a number of commercial scale projects. At 180m long, 4m diameter and weighing around 1350 tons (mostly sand ballast), the P2 Pelamis is wider, longer and heavier than the P1 design machine. This allows the Pelamis to capture more energy while substantially reducing the cost per MW. Comprised of five tubes with four joints, the P2 has an extra tube section and an extra power module. An improved power take off system for the P2 allows higher efficiencies, enhanced control resolution and increased reliability.
