#5. Piper Alpha Oil Rig $3.4 Billion

The world's worst off-shore oil disaster. At one time, it was the world's single largest oil producer, spewing out 317,000 barrels of oil per day.. On July 6, 1988, as part of routine maintenance,technicians removed and checked safety valves which were essential inpreventing dangerous build-up of liquid gas. There were 100 identical safety valves which were checked. Unfortunately, the technicians made a mistake and forgot to replace one of them. At 10 PM that same night,a technician pressed a start button for the liquid gas pumps and the world's most expensive oil rig accident was set in motion.Within 2 hours, the 300 foot platform was engulfed in flames. It eventually collapsed, killing 167 workers and resulting in $3.4Billion in damages.

*AH!!!!! This is Malaysia Good Example.. Always Employ experts to do it. .Cos We all Dunno how ma.. (they say like that oh..) so Better to be safe than SORRY!

#4. Challenger Explosion $5.5 Billion

The Space Shuttle Challenger was destroyed 73 seconds after takeoffdue on January 28, 1986 due to a faulty O-ring. It failed to seal one of the joints, allowing pressurized gas to reach the outside. This inturn caused the external tank to dump its payload of liquid hydrogen causing a massive explosion. The cost of replacing the Space Shuttlewas $2 billion in 1986 ($4.5 billion in today's dollars). The cost of investigation, problem correction, and replacement of lost equipmentcost $450 million from 1986-1987 ($1 Billion in today's dollars).
