Managers at oil giant BP PLC decided
to forge ahead in finishing work on the doomed Deepwater Horizon rig despite
some tests suggesting that highly combustible gas had seeped into the well, according to testimony
released by congressional
investigators and documents seen by The Wall Street Journal.
国国会调查人员发布的证词和《华尔街日报》见到的文件显示，虽然曾有测试表明后来发生事故的"深水地平线"(Deepwater Horizon)钻井平台下的油井渗入了高可燃气体，但石油巨头英国石油公司(BP PLC)的管理人员还是决定加快完成钻井平台上的工作。
The move to start withdrawing heavy fluid that prevents gas from escaping the well, despite
some worrisome tests and before a final cement
plug could be placed in the well, raises questions about the judgments made on the rig in the hours before an explosion
erupted into the night air of April 20, killing 11 workers and leaving crude oil pouring into the Gulf of Mexico.
Testimony from two contractors says mud was withdrawn
before a final cement
plug, which would have been one more safeguard
against natural gas surging from the well, was poured. Once natural gas began to rise inside the well, the last safeguard
, a 450-ton set of valves called a blowout preventer, failed to do its job, possibly due to a defect
, documents produced by congressional
investigators show. The oil platform
was soon engulfed in flames.
and the chief executive
of rig owner Transocean Ltd. told lawmakers Wednesday that discrepancies in key pressure
tests on the afternoon of the explosion
should have raised alarms.
They should 'lead to a conclusion
that there was something happening
in the well bore that shouldn't be happening
,' Transocean CEO Steven Newman told the House Energy and Commerce Committee.
Transocean首席执行长纽曼(Steven Newman)对众议院能源和商务委员会(House Energy and Commerce Committee)说，他们应该得出结论认为，钻井孔里正在发生某种不应该发生的事情。
BP America Chairman Lamar McKay told the panel 'that discrepancy is critical
, and the investigation
will have to tear that apart piece by piece.'
英国石油美国公司(BP America)董事长麦凯(Lamar McKay)对该委员会说，这种异常情况至关重要，调查将需要加以逐一分析。
Critical details remain unclear, including who made the decisions to push ahead with operations to close down the well despite
signs of trouble, and whether federal
regulators were consulted and signed off. It's also unclear how natural gas first made its way into the well, which was supposed
to be sealed on the sides and bottom.
