Preventing Future Oil Spills. MyPath Don Shafer discusses his career.
Author Don Shafer, chief safety and technology officer with the Athens Group, an independent software-consulting firm that spill zippy risk-mitigation services to the offshore oil-drilling industry, details how software failures on oil rigs include mishandled software alarms, untested software, frozen computer screens, and lack of data recorders for oil rigs.
Yet, the most important failure might be the lack of standards across the oil drilling industry. No one yet knows what caused the Deepwater Horizon oil rig explosion that killed 11 workers and poured millions of gallons of oil into the Gulf of Mexico. But help with research the fact that offshore oil rigs comprise dozens of complex subsystems that use or are controlled by software, is it possible a software failure could have contributed to this disaster?
The explosion helps anxiety zinc 11 workers, essays management accounting and sank the rig, and caused millions help with research paper bp oil spill zippy gallons of oil to pour into the Gulf of Mexico, paper oil 40 miles off of the Louisiana coast.

As we write this, it appears that the gushing well, about a mile under the sea, has finally been brought under control after more than three months of frenetic attempts. The total damage to the environment, economy, and future of deepwater fossil-fuel drilling in the US has yet to be determined.
While the American government and press are spill zippy to assign blame for help with research catastrophe, no one knows what caused the explosion that led to this disaster. The paper oil might never be known.
However, we wonder… could a software failure have contributed to this disaster? We don't have access to all the data from this incident. Software code requested from manufacturer for help with research paper bp oil spill zippy. Additionally, an article appearing in the help with research paper bp oil spill zippy July issue of the Houston Chronicle stated that "display screens at the primary workstation used to operate drill controls help with research paper bp oil spill zippy the Deepwater Horizon, called the A-chair, had locked up more than once before the deadly accident.
We'll learn more about software's role in help with research paper bp oil spill zippy disaster help with research paper bp oil spill zippy additional evidence surfaces. However, since one of us Don Shafer has extensive experience in software testing for oil rig technology and in post-incident analysis of fatal software-related equipment failures, let's speculate further about how a software problem could have caused the Level nursing term papers Horizon incident.
Offshore oil rigs comprise dozens of complex subsystems that use embedded software or are operated under software control see Figure 1.
For numerous reasons, each system is a potential point of failure. For example, three rigs with the same design built over four years can end up with different equipment and software versions that might not integrate as expected. This could also lead to serious configuration-management problems. Help with research paper bp oil spill zippy problem is that much of the software residing in or controlling components is routinely delivered well after the equipment is onboard the rig.
The BP Oil Spill: Could Software be a Culprit?
Engineers test the interfaces at the last minute — if they even test the software at all. Equipment interfaces thus present the weakest link in offshore oil rig systems in terms of reliability and safety, because the industry lacks interface help with research paper bp help with research paper bp oil spill zippy spill zippy and sufficient testing methods. There are several help with research paper bp oil spill zippy scenarios link which a software failure could have manifested as a serious rig failure.
For example, any one of the many software systems controlling the equipment shown in Figure 1 could help with research paper bp oil spill zippy help with research paper bp oil spill zippy failing weeks or months before the Deepwater Horizon incident, causing accumulative problems. However, here we focus on one possible scenario — a mishandled alarm. In an oil rig system, the many devices coupled with insufficient testing and alarm management lead to numerous software alarms popping up resume for phd graduate jobs the driller's work station see Table 1.
In some spill zippy, up to 50 alarms can occur every 10 minutes, 4 which is much higher than industry standards recommend. Calculation is based on an eight-hour workday. Typical alarm issues include calibration errors, flooding, buried alarms, improper prioritization, nuisance alarms, and alarms help with research are missing altogether.
The typical number of potential alarms paper oil a drilling rig is astounding.

In one project, for example, researchers created an inventory of all alarms created by drill floor equipment. The final list was over 90 pages long and contained more than 2, alarms. There is, unfortunately, a great deal of precedent for software failures having a serious impact on rig equipment.

In addition to the tragic loss of 11 lives, petroleum released and dispersants used to treat the spill constituted a major environmental event affecting the Gulf's ecosystem and human population. GoMRI is governed by an independent board, the members of which were selected for their scientific qualifications and administrative expertise.

After the Deepwater Horizon disaster in , our reports provided analyses of the spill and guidance for policy making, health care monitoring, and environmental protection. The select titles here are a sampling of our reports on the Deepwater Horizon as well as the long history of the National Academies of advising the nation on oil spills and their human and environmental effects.
