The Space Shuttle Columbia disaster was a fatal incident in the United States space program that occurred on February 1, 2003, when the Space Shuttle Columbia (OV-102) disintegrated as it re-entered the atmosphere, killing all seven crew members. The disaster was the second fatal accident in the Space Shuttle program, after the 1986 breakup of Challenger soon after liftoff.
During the launch of STS-107, Columbia’s 28th mission, a piece of foam insulation broke off from the Space Shuttle external tank and struck the left wing of the orbiter. Similar foam shedding had occurred during previous shuttle launches, causing damage that ranged from minor to nearly catastrophic, but some engineers suspected that the damage to Columbia was more serious. Before re-entry, NASA managers had limited the investigation, reasoning that the crew could not have fixed the problem if it had been confirmed. When Columbia re-entered the atmosphere of Earth, the damage allowed hot atmospheric gases to penetrate the heat shield and destroy the internal wing structure, which caused the spacecraft to become unstable and break apart.

Flooding and capsize of ro-ro passenger ferry Herald of Free Enterprise with loss of 193 lives
On the 6th March 1987 the Roll on/Roll off passenger and freight ferry HERALD OF FREE ENTERPRISE (‘HERALD’) under the command of Captain David Lewry sailed from Number 12 berth in the inner harbour at Zeebrugge at 18.05 G.M.T. The HERALD was manned by a crew of 80 hands all told and was laden with 81 cars, 47 freight vehicles and three other vehicles.
Approximately 459 passengers had embarked for the voyage to Dover, which they expected to be completed without incident in the prevailing good weather. There was a light easterly breeze and very little sea or swell. The HERALD passed the outer mole at 18.24. She capsized about four minutes later. During the final moments the HERALD turned rapidly to starboard and was prevented from sinking totally by reason only that her port side took the ground in shallow water. The HERALD came to rest on a heading of 136° with her starboard side above the surface. Water rapidly filled the ship below the surface level with the result that not less than 150 passengers and 38 members of the crew lost their lives. Many others were injured.

The Alexander L Kielland was a semi-submersible platform accommodating the workers of the bridge-linked Edda oil rig in the Ekofisk field, approximately 235 miles east of Dundee, Scotland, in the Norwegian Continental Shelf. The Phillips Petroleum-operated platform capsized in March 1980, killing 123 people.
Only 89 out of 212 workers survived the accident and most died by drowning as the platform turned upside-down in deep waters. The platform capsized after the failure of one of the bracings attached to one leg of the five-legged platform structure after strong winds created waves of up to 12 m high on the day of the accident.

At approximately 7:20 a.m. on April 3, 2017, the bottom of a steam condensate (hot water) storage tank catastrophically failed at the Loy-Lange Box Company (LLBC), located at 222 Russell Boulevard in St. Louis, Missouri. The 1952-pound, 30-inch diameter by 17-½-feet long steel tank, called a Semi-Closed Receiver (SCR)4 contained about 510 gallons condensed steam (water at about 330 °F and 100 psig.) Condensate from the vertically-mounted SCR was normally sent to two associated steam generators.
As the pressure in the tank suddenly dropped due to the failure of the tank bottom, a portion of the water in the SCR instantaneously exploded into steam, resulting in an increase in volume of about 75 times the volume of the SCR. A steam explosion of this type is extremely hazardous. The energy released was equivalent to about 350 pounds of TNT. Some of that energy dissipated when the escaping steam condensed to water, but the surveillance video from a nearby custom work truck shop clearly shows the power of the explosion and the effect on the building, as does the damage evident after the event.
The force of the steam explosion exiting the bottom of the SCR destroyed a large portion of the LLBC facility, and launched the storage tank like a rocket through the roof. One LLBC employee was fatally injured, and a second was left in critical condition.
Even after pulling loose from all of the piping and floor attachments, and crashing up through the structure of the building and out through the roof, the 1952-pound SCR was still traveling at about 120 mph. It rose to about 425 feet above street level and traveled laterally across about 520 feet. It remained airborne for over 10 seconds. As it fell, the SCR crashed through the roof of Faultless Healthcare Linen’s property at 2030 S. Broadway, fatally injuring three individuals.

A total of 638 workers were evacuated from this flotel after it began to lean to one side when water entered a pontoon. The flotel was located about 80 kilometres offshore Campeche, Mexico. There were no injuries reported as a result of the sudden inclination. It was reported that a total loss of the flotel resulted.

A natural gas drilling rig sank in the Caribbean Sea, but all 95 workers were evacuated safely and there was no reported leakage. The sinking was caused by a sudden surge of water entering one of the submarine rafts that the platform legs floated on. Automatic subsea safety valves meant the well was secure and no leakage of oil occurred.

An 18″ medium pressure (MP) steam main located near to the A904 Boness road ruptured at 23:18 p.m. on 7th June 2000 resulting in a significant loss of MP steam directly into the atmosphere. The steam leak damaged fencing immediately adjacent to the ruptured pipework. Debris and steam was blown across the road until the leak was isolated. The leak also caused significant noise (similar to a jet engine) being heard in the Grangemouth area. A member of the public walking the dog 300 metres away sustained rib injuries from tripping over the dog.
There was significant disruption to the steam supply system for the Complex for approximately one hour until the steam leak could be isolated and as a result of the incident the A904 Boness road was closed for public access until 22nd June whilst repairs were carried out.
The medium pressure (MP) steam main rupture had the potential to cause fatal injury and environmental impact, although no serious injury occurred, and there was only short term impact on the environment.
The critical factors that led to the incident were created a week earlier. Significant levels of condensate built up in the steam line following isolation of a steam trap to gain access for inspection of the tunnel, after the culvert was flooded following the power distribution failure.
The immediate cause of the catastrophic failure of an MP steam distribution pipeline was “condensation induced water hammer” which caused gross overpressure.
• Management of change (change control procedures);
• Failure to adequately investigate significant plant upsets and to carry out risk assessments;
• Operating regimes and lack of certain site standards;
• Inspection and maintenance of equipment;
• Management structure and organisation;
• Failure to learn lessons from previous incidents/events on-site.
