Questions and Answers

What was a primary reason for the failure of the top-kill method during the Deepwater Horizon disaster?

  • Drilling mud froze solid from hydrate formation.
  • Not enough funds to buy enough drilling mud.
  • The pressure was too high and kept blowing out the junk and drilling mud mixture. (correct)
  • Insufficient material flow into the well.

During the Deepwater Horizon disaster, what was identified as the worst-case scenario?

  • Mass civil unrest.
  • Firestorm if the surface oil slick ignited.
  • Massive explosion that sunk disaster response vessels on the surface.
  • Complete integrity failure of the well leading to leaking from the seabed floor. (correct)

What is the recommended action regarding offshore drilling after the Deepwater Horizon disaster?

  • Yes, but with more stringent safety measures. (correct)
  • No, it's not worth the risk.
  • Only in shallow, fair-weathered waters.

Study Notes

Team Performance Evaluation

  • Team worked well together, leveraging individual strengths
  • Effective task division and open communication
  • Resolved scheduling conflicts
  • Met project deadlines
  • Potential for improvement: more frequent progress check-ins to improve accountability and reduce last-minute stress.

Course Feedback

  • The course was well-organized with clear deadlines, relevant examples, and ample resources.
  • A suggestion for improvement: include a class activity where students switch groups to gain diverse perspectives and foster idea exchange.

Equality vs. Equity

  • Equality: everyone receives the same resources (e.g., bicycles).
  • Equity: everyone receives resources based on needs to ensure equal opportunities (e.g., tailoring bicycle options to individual needs).

Course Topics from Videos

  • Focus on response questions from videos and class discussions
  • Review 4 classical ethical theories (Mill's utilitarianism, Kant's formalism, Locke's rights ethics, Aristotle's virtue ethics).
  • Understand 3 standards of responsibility in engineering (malpractice model, reasonable care model, good works model) and their application.
  • Review fundamental concepts of engineering design and management, including Pugh matrix, Gantt chart, PERT chart.
  • Expect questions on basic engineering disaster examples, like the Burj Al Arab support, inspiration from the Millau Bridge, etc

Engineering Challenges

  • The shape of the Burj Al Arab hotel architecture was inspired by the sail of a dhow.
  • Sand Island stability: friction between the support rods and the sand.
  • Engineers managed differential thermal expansion in steel trussing using eccentric (cam) joints and assembling at night when things were cool.
  • Water jet speed: approximately 20 cm/s (from the video on water fountains).
  • Questions from the video on specific engineering concepts.
  • Questions from the video relating to the response questions.

Engineering Values

  • Identify the non-reusable parts of the shuttle.

Submarine Anechoic Tiles

  • Air voids in the material change the resonant frequency, absorbing sound.

Water Droplet Attenuation

  • Water droplets are accelerated and shattered, absorbing shock energy from the flow behind the shock.

Engineering Disasters

  • Hammond claims that blunt orbiter noses deflect air around wings, even if without wings. Deflection is due to heated air layers being pushed away from the vehicle, acting as insulation.
