Missing data causing rig reconstruction mystery
A “black box” can reveal why an airplane crashed or how fast a car was going in the instant before an accident. Yet there are no records of a critical safety test supposedly performed during the fateful hours before the Deepwater Horizon oil rig exploded in the Gulf of Mexico.
They went [...]
BP faces choppy waters after huge oil spill
Stopping a potentially devastating slick from a damaged oil well in the Gulf of Mexico is only part of the headache currently facing BP.
The company also faces a massive clean-up bill, plus legal action from those affected and possible damage to its global brand.
It is not the first time BP has faced [...]
Oil Spill Gulf of Mexico 2010 UPDATE
New data show that the oil spill in the Gulf of Mexico is five times larger than it was estimated previously! The situation is rapidly getting out of control, and Coast Guard officials have announced they will try to burn portions of the oil in an effort of oil spill containment.
The [...]
Oil drilling accidents prompted new safety rules
NEW ORLEANS – Federal regulators did not need this week’s explosion aboard a state-of-the-art oil rig to know the offshore drilling industry needed new safety rules: Dozens of deaths and hundreds of injuries over the last several years had already convinced them that changes were needed.
The U.S. Minerals and Management Service is [...]
Gas compressor problems
Referring back to Figure 10—1, remember that we have compared the actual gas compressor speed to the speed indicated by the curve that passes through point “A”. We calculated point “A” from the natural gas flow, and the observed suction and discharge pressure. We said that if the measured gas compressor speed exceeded the speed [...]

One way of looking at a gas turbine centrifugal compressor is that the combustion air compressor must pump sufficient air to support combustion across the turbine blades as needed to spin the gas compressor at its required speed. Any factors which reduce the flow delivered by the combustion air compressor will reduce horsepower available to [...]

Gas turbines are limited, as are all rotating assemblies, by either speed or power. For an electric motor, the power limit is manifested by maximum amperage, (more precisely, the maximum permissible winding temperature). The situation with gas turbines is similar. The ultimate amount of power (i.e. work, horsepower), that can be developed by the turbine [...]
