Tomorrow is the 20th anniversary of the worst offshore oil disaster.
The Piper Alpha was a North Sea oil production platform operated by Occidental Petroleum (Caledonia) Ltd. It accounted for around ten per cent of the oil and gas production from the North Sea at the time. The platform began production in 1976 first as an oil platform and then later converted to gas production. An explosion and resulting fire destroyed it on July 6, 1988, killing 167 men. Total insured loss was $ 3.4 billion. To date it is the world’s worst offshore oil disaster.
The Amazing site Oil Rig Disasters writes about the Piper Alpha. they tell us:
On 06 July 1988, work began on one of two condensate-injection pumps, designated A and B, which were used to compress gas on the platform prior to transport of the gas to Flotta. A pressure safety valve was removed from compressor A for recalibration and re-certification and two blind flanges were fitted onto the open pipework. The dayshift crew then finished for the day.
During the evening of 06 July, pump B tripped and the nightshift crew decided that pump A should be brought back into service. Once the pump was operational, gas condensate leaked from the two blind flanges and, at around 2200 hours, the gas ignited and exploded, causing fires and damage to other areas with the further release of gas and oil. Some twenty minutes later, the Tartan gas riser failed and a second major explosion occurred followed by widespread fire. Fifty minutes later, at around 2250 hours, the MCP-01 gas riser failed resulting in a third major explosion. Further explosions then ensued, followed by the eventual structural collapse of a significant proportion of the installation.

If we only had one technology related wish for 2008 it would be that every mariner watched this video. Reminder: This is important people!
FROM WIRED:
While micro-messaging service Twitter may be one of the best tools for citizen reporting in emergencies such as the Southern California wildfires, the service’s real usefulness is its ability to get messages to users’ friends and family and provide evacuation updates — even when cell networks are overloaded, according to homeland security consultant W. David Stephenson.
As important as the updates you wrote about, they’re nowhere near as important as using Twitter to let your family know you’re ok (instead of cell calls, which every time they’re used in disasters end up crashing the network — and don’t get through, either): because they’re packet based, they’re cued up until they can route around obstacles or gaps in the network, and the 140-character limit means they take up a tiny amount of bandwidth, leaving it for those who need it most.
Even cooler, Stephenson tells THREAT LEVEL, are the Red Cross’s Twitter channels.
* The redcross channel lets them push information during a mass evacuation. Since cellphone customers can sign up for Twitter ‘on the fly,’ they will encourage evacuees to text ‘FOLLOW REDCROSS’ to 40404, and sign up for updates. The messages will include information about where the shelters are, distribution sites, and other contact info.
* The safeandwell channel is used more for inbound communication. Those who text ‘FOLLOW SAFEANDWELL’ to 40404 will automatically be followed back. That means they can send their private information as a Direct Message to the American Red Cross. (’D SAFEANDWELL Larry Melman, 205-xxx-xxxx, 1313 Mockingbird Lane, Bay Minette, is safe in a shelter.’) That maintains the privacy of the individual, and also serves to funnel the information to a centralized database.
