Douglas H. Brown, the chief mechanic for the Deepwater Horizon, testified Wednesday that he witnessed a “skirmish” on the rig between a BP well site leader and crew members employed by Transocean, the rig’s owner, the morning of the blast.
¶ Mr. Brown said the disagreement followed BP’s decision to replace heavy drilling fluid with lighter saltwater before the well was sealed with a final cement plug.
¶ “Well, this is how it’s going to be,” the BP official said, according to Mr. Brown.
¶ Mr. Gowers declined to answer questions about workers’ accusations or about whether cost may have factored into the company’s decision to use the casing system it chose for the Deepwater Horizon.

For example, Representative Nick J. Rahall II, Democrat of West Virginia and the chairman of the committee, said BP executives would face questions about why they let workers from Schlumberger, a drilling-services contractor, leave the morning of the accident without conducting a special test on the quality of the cement work.
Engineers have described these tests, called cement bond logs, as an important tool for ensuring cement integrity.
Precisely. BP did not want the CBL tests to be carried out because the plan was for the well to blow.
