On the Deepwater Horizon issue we capture the date as April 20, and the time of 9: An important difference was confusing test pressure results. To view a PDF showing the eight key findings, click here or on the button above. The rig itself capsized and sank, and will not be used again.
The cap was finally placed on July 12th and the flow was choked on July 15th. The next plan aimed to end the flow from Macondo well by ramming heavy mud and cement directly into the well itself.
The static kill was completed on August 4th. The magnitude of this incident is defined by the impact to the goals. Another person might say that the problem was the explosion on the rig, and a third person could say that the problem was the worker fatalities.
Additionally, the magnitude of the spill directly resulted from was caused by the blowout preventer BOP not sealing the well, as designed, for reasons that are not entirely clear. More solutions were still needed. The amount of detail provided in an analysis must be adequate to determine effective solutions in reducing the impacts to the goals.
In an investigation there can be several pieces of information that need to be captured when specifying the location. Now the flow was controlled, but the Macondo well was still releasing oil at a high rate.
Additionally, the crew did not recognize there was a problem until the blowout occurred. The uncontrolled flow up the riser blowout was caused by a failure of the well seat due to an ineffective cement job and failure of the barriers in the shoe track, which allowed the hydrocarbons to enter the production casing, for unknown reasons.
No accidents, no harm to people, and no damage to the environment. Three days later, the operation was stopped when it became clear the top kill was no match for the flow from the well.
The RITT was partially successful. There were other goals that were affected but the magnitude of the loss of life makes any other goals less significant. The Deepwater Horizon oil rig was in the final stages of exploratory drilling at the Macondo well in the Gulf of Mexico when disaster struck.
This is because the ambiguous pressure test results we talked about earlier were misinterpreted. The two impacted goals that we will use for our analysis are the safety goal and the environmental goal.
The Cause Map starts by writing down the goals that were affected as defined in the problem outline. For Deepwater Horizon, the safety goal was impacted because of the1 1 lives that were lost and 17 injures.
This cap was designed to seal tightly, capture all the oil and divert it to two surface ships. The MGS was not designed for large flow rates. The first plan action item was to attempt to use functionality within the blowout preventer BOP which had failed to seal the well.
When captures the timing of the issue and also has a line for what was different or unusual in this occurrence. The reminders of the tragedy will remain, and hopefully the lessons learned will be applied to other incidents to ensure that safety is maximized in difficult environments in the future.
The question of what was different is fundamental in any investigation.BP Oil Spill Chait, J, (). Dear Leader. New Republic, (10), Retrieve June 21,from Academic Search Premier. This article discusses the present oil spill in the Gulf of Mexico.
The president’s has not changed the Minerals Management Service. Nov 20, · The BP oil spill in the Gulf of Mexico is considered to be the “largest accidental marine oil spill in the history of petroleum industry, being 8%% larger in volume that the previous largest oil spill, the Ixtos I oil spill” (Holland & Schemwell,p.

Oil Spill Risk Analysis Model (OSRAM) Information to Be Used In Oil Spill Response Plans A Notice to Lessees, Operators, and Pipeline Right-Of-Way Holders (NTL) was effective on August 10, (BSEE NTL N06) that provides additional guidance on the review and update of.
We’ll use the Cause Mapping process to provide an analysis of the issues related to the Deepwater Horizon explosion and oil spill. The Cause Mapping method utilizes three steps: 1) Define the problem, 2) Conduct the analysis and 3) Identify the best solutions.
