INTRODUCTION

2

• Engineering profession already has Competence and Ethics standards
• After case studies, Engineers’ Performance is another factor affect the

engineering deliverable

Good engineering deliverable

THREE LEGGED STOOL

3

• Performance is the missing ‘third leg of the stool’

Ethic, competency and performance (sources: PPIR)

PPIR

4 PPIR eight elements (source: PPIR)

• The Warren Centre introduces the Professional Performance innovation

and risk (PPIR) protocol

5

Case studies of failure should be made a part of the vocabulary of every engineer so that he or she can recall or recite them when something in a new design

• r design process is suggestive of what went wrong in

the case study. – Henry Petroski

OBJECTIVE

6 Structure for each case study

Our Final Report outlines:

• Identify the importance of the PPIR
• Detailed investigation into six case studies
• Provides analysis of failures bases on the eight elements of PPIR
• Highlights potential outcomes using the PPIR protocol

CIVIL ENGINEERING FAILURES

7 London bridge, Syncrude tailings dam, Opera house, London city

Case Studies 1: Ok Tedi Tailings Dam

8 Ok Tedi Mine site

Description

• Dumped excavation material at an unstable slope
• On 6 January 1984, a landslide occurred
• No people died due to this incident

Case Studies 1: Ok Tedi Tailings Dam

9

Competence to Act

• Many experienced and senior experts had

visited the site

• Rechecking the aerial photographs

Risk Management

• Fast-tracking method
• Pervious assumptions proved inaccurate

Case Study 2: Fundão Tailings Dam

10 The village of Bento Rodrigues after the disaster (source: Wikipedia)

Description

• 5th of November 2015, failure occurred at the left abutment of the Fundão Tailings dam
• Destroying the ecosystem of the Doce River
• 18 casualties
• Direct cause: liquefaction

Mud reach Atlantic Ocean (source: Wikipedia)

Case Study 2: Fundão Tailings Dam

11

Engineering Task Management

• The quality of drain system was unacceptable

Before incident happened (source: Investigation report) After incident happened (source: Investigation report)

Risk Management

• Solved visible problem
• Did not consider its impact on whole project

MECHNANICAL ENGINEERING FAILURES

12 Piping system

CASE STUDY 3: HMAS WESTRALIA FIRE

13 HMAS Westralia alongside HMAS Regina (source: Wikipedia)

Description

• 5th of May 1998, a significant fuel leak was appeared at a cylinder
• Nearby exposed hot engine ignited the fuel
• Four casualties all from acute smoke inhalation
• Incorrect flexible hoses was used

The area where the fire started. (source: Investigation report)

CASE STUDY 3: HMAS WESTRALIA FIRE

14

Competence to Act

• Involved engineers have insufficient knowledge

to carry out this project

Filed supply hose on the cylinder (source: Investigation report) The indicator cocks at cylinders 8, 9 & 10. (source: Investigation report)

Relevant Parties and Other Stakeholders

• Lack of proper approval procedure
• Stakeholders: ADI (contractor carry out

maintenance program) and ENZED (subcontractor carry out the selection of the flexible hoses)

CASE STUDY 4: FLIXBOROUGH EXPLOSION

15 The Fires Seen From South-west

Description

• Occurred in a caprolactam plant
• Leak from reactor circuit
• Ignited by furnace
• Killing 28 and injuring 36 inside the Plant
• Burned for 10 days

CASE STUDY 4: FLIXBOROUGH EXPLOSION

16 Creases in Bellows Evident in a Simulation Test for 20-inch By-pass Assembly Reactor 5 Showing Crack Leading to Removal and Replacement by By-pass

CASE STUDY 4: FLIXBOROUGH EXPLOSION

17

The Engineering Task

• Replace reactor using the by-pass
• Aware of the task and instructions
• Poor design without liaising with professionals

Design of 20-inch By-pass Assembly Fliborough Disaster without Quality Assurance Process

Engineering Task Management

• No measures of Quality Assurance
• No strength test

CHEMICAL ENGINEERING FAILURES

18 Chemical Disaster

CASE STUDY 5: BP TEXAS CITY REFINERY EXPLOSION

19 Placement Surrounding the ISOM Unit

Description

• 15 deaths and 180 injured
• Release and overheating of combustible vapour cloud
• All fatalities were in or near office trailers
• Occurred in start-up of isomerisation (ISOM)

Emergency of Texas City Refinery Explosion

CASE STUDY 5: BP TEXAS CITY REFINERY EXPLOSION

Engineering Task Management

• Supervisor decision
• Board Operator response
• Night Lead Operator irresponsible attitude

The Engineering Task

• BP Board of Director (Assess performance)
• Night Board Operator (Logbook)
• Day Supervisor (Communication)

CASE STUDY 6: TIANJIN PORT EXPLOSION

21

Description

• 165 deaths, 8 missing and 798 injured on 12 August 2015
• Nitrocellulose self-ignition
• Ignited other dangerous goods and exploded
• Six severe conflagration points and couples of small burning spots
• Equivalent to 450 tonnes of TNT

CASE STUDY 6: TIANJIN PORT EXPLOSION

22

Statutory Requirements and public interest

• Near communities
• High volume of chemical goods
• Without management system and emergency strategy

Risk Management

• Without conducting risks
• No professional engineer
• Potential risk

Clean the Ruins After Explosion Investigation After Explosion

KEY FINDINGS

23

• A need for PPIR performance protocol
• Changes in management process
• Risk management
• The application involves in engineering task
• Internationally recognised protocol

CONCLUSION
