Outline
• Offshore Engineering
• Pipeline Engineering Design
• Floating Production, Storage and Offloading Vessels
Offshore Engineering Challenges
• Deepwater Horizon oil rig sank in April, 2010
• Flow contained 3 months later
– 4.9 million barrels spilled
– 176,000 km2 area polluted
– $4.5 billion fine
– $45 billion settlement
Offshore Engineering by Nigerians
Bonga FPSO
•
•
•
•
Production Capacity – 225kbopd
Storage capacity – 2 million barrels
Commissioned - November 2005
Cracks appeared by October 2008
Involving Nigerians
• Nigerian Content
regulations forced Shell to
look for Nigerians
• Shell International
reluctant and apprehensive
• Shell ready to invite
original designers if
Nigerians not able to solve
Flare Boom Failure
• Options
• Shut down
• Continue
temporarily
• Engineers to
conduct failure
analysis
• Crack Study
duration – 2
months

Taking Nigerian Engineering to the World
Results have been presented at various conferences
• Offshore West Africa, Ghana, 2012
• Nigerian Oil & Gas Technology Conference, Lagos,
2013
• 2nd FLNG/FPSO Conference, Guangzhou, China,
2014
Offshore Engineering
• Extreme weather conditions makes offshore
engineering challenging
• Very little tolerance for errors
• Huge risks present could result in massive
– Loss of lives
– Material losses
– Facility abandonment
– Environmental degradation
