STORYLINE:
Investigators looking into what went wrong in the Gulf of Mexico oil spill are a step closer to answers now that a key piece of evidence is secure aboard a boat.
Engineers took just over 29 hours to lift the 50-foot (15.24-metre), 300-ton blowout preventer from a mile (1.6 kilometre) beneath the sea, and the five-story-high device looked largely intact Saturday night with black stains on the yellow metal.
FBI agents were among the 137 people aboard the Helix Q4000 vessel, taking photos and video of the device.
They will escort it back to a NASA facility in Louisiana for analysis.
The AP was the only news outlet with a print reporter and photographer on board the ship.
The blowout preventer was placed into a metal contraption specifically designed to hold the massive device at 9:16 p.m. Saturday (0216 GMT Sunday).
As a large hatch opened up on the Helix to allow the blowout preventer to pass through, several hundred feet (metres) of light sheen could be seen near the boat, though crews weren't exactly sure what it was.
As it was manoeuvred into place, crew members were silent and water dripped off the device.
Crews had been delayed raising the device after icelike crystals, called hydrates, formed on it.
The device couldn't be safely lifted from the water until the hydrates melted because the hydrates are combustible, said Darin Hilton, the captain of the Helix Q4000.
Hydrates form when gases such as methane mix with water under high pressure and cold temperatures.
The crystals caused BP PLC problems in May, when hydrates formed on a 100-ton, four-story dome the company tried to place over the leak to contain it.
The April 20 explosion aboard the Deepwater Horizon killed 11 workers and led to 206 million gallons (780 million litres) of oil spewing from BP PLC's undersea well.
Investigators know the explosion was triggered by a bubble of methane gas that escaped from the well and shot up the drill column, expanding quickly as it burst through several seals and barriers before igniting.
But they don't know exactly how or why the gas escaped.
And they don't know why the blowout preventer didn't seal the well pipe at the sea bottom after the eruption, as it was supposed to.
While the device didn't close - or may have closed partially - investigative hearings have produced no clear picture of why it didn't plug the well.
A temporary cap that stopped oil from gushing into the Gulf in mid-July was removed Thursday.
No more oil was expected to leak into the sea, but crews were standing by with collection vessels just in case.
The government said a new blowout preventer was placed on the blown-out well late Friday.
Officials wanted to replace the failed blowout preventer first to deal with any pressure that is caused when a relief well BP has been drilling intersects the blown-out well.

That thing is massive.
We need to remember this and make sure no such incident happens again
Drilling in the deep is risky but must be done until you myself and others are willing to do without plastic rubber and many other comforts we will continue to drill , lessons have been learned and will continue but solar and electric is not the answer they have very high risks as well the making and disposal of batteries for one.
BP deep horizon used my design caphead to stop the leak. I submitted my design to the " horizon helpline" July 2010. Being. I didn't patent my design BP emailed me back and stated my design was useless. Several weeks after submitting the caphead was used to stop the leak. I still have copies of my design I had submitted, as well as emails from the horizon helpline. They claim since I had no patent they could claim intellectual knowledge. My best explanation for what happened is that no contingency had been used in the spill. No spill response or drills. 80 days to contain a leak verifies that. On land based pipelines safety test records of pipelines and safety valves is overseen by the dept of public transportation. Meaning the horizon crew knew prior to the spill that they had problems with the blowout prevention valve. Whoever does the overseeing safety checks signed off allowing the deep horizon to keep producing and gambled nothing would go wrong. The horizon / BP crew had everything they needed but no plan until I submitted my design. This also indicates that on land based oil producing wells companies that specialize in disaster repairs like" boots and coots" exist, nothing for open water oil production platforms. My intention is to start my own company to deal with deep water repairs.
How old are you? 70?
Do it instead of bitching on RUclips phony
If this is true, it’s your own fault.
Rip 11 guys
Why are we standing under a suspended load?
physics loves these objects... especially if that hoist lets go for ANY REASON :
Force = mass X acceleration
Weight = mass X gravity
potential energy = mass X gravity X height .
acceleration = change in velocity / change in time
velocity = change in position / change in time
let us not forget shock load as a sudden gust of wind could make the load tilt and over stress one side of the cable and break it, or a sudden wave could also do the same, or frankly anything that could have made it bounce just a little.
Dumb question:::: how much does one of those cost ???
I thought this thing would be half the size at max
Somebody hurry up and unlatch those elevators real quick
The type of blowout prevention valves cannot be tested to verify they are operational until needed and the hydraulic rams leave the well inaccessible. The well once brought under control cannot be repaired or sealed if abandoned. Bop valves need testing on a periodic basis to verify the bop is operational. If the bop valve needs repair or replacement there is nothing to isolate pressure unless a spill is created. There are valve designs such as mine that can handle a kick or spike in pressure and not endanger the crew or equipment or disable the well. I also am in the process of starting my own deep water repair company specializing in ocean based drill platforms. I am working with a major company in designing and marketing safer bop valves. The current type one activated leaves the well unusable or will create a spill.
1) I thought the choke and kill lines access below the rams on this BOP so the well is accessible during a LMRP unlatch. 2) If they were to shut the well in as expected using the pipe rams and shear rams the well could be repaired. They would relatch the LMRP and go with an overshot. I dont know why you say the well cannot be repaired. Unless you are implying they cannot remove the BOP while in well control. Thats a given. 3) Im not sure what kind of technologies you are attempting to use in a newer style BOP but I wish you luck. Its going to cost you a large fortune to get this bad bear up and running. In addition API standards are constantly changing which means the second you have it working....they'll make you change it. Good luck.
