Petrobras Platform 36 images - Coggle Diagram

- - - - First explosion took place at 12:22am March 15, due to mechanical failure
      - Second intense explosion took place at 12:39am due to natural gas release
        
        Killing 11 people in charge of the emergency response
      - Drainage operation of the drain storage tank in the aft port column on 14 March 2001
        
        Main cause of the incident
      - There was an evacuation of 138 people at 1:44am March 15, lasting 2hr 30min
        
        No life boats were used, only cranes and personal transfer basket
      - At 8:15am March 15 the platform was at 20 degrees and water level reached the aft starboard chain locker entry
      - The platform slowly submerged and sank at 11:41am March 20
    - - Semi-public Brazilian company
      - Rio de Janeiro
  - - - 175 people were on board
      - 138 were able to evacuate using cranes
      - Remaining were able to evacuate by helicopter
      - 11 workers were killed
- - - - Flooding of the column and pontoon
      - Failure within the ventilation system
      - Two seawater pumps were out of operation
  - - - Insufficient personnel capability within emergency procedures and stability control
      - Oil workers had lack of training within emergency situation
  - - - Ineffective communication system
      - Inefficient consultation
      - No coordination with emergency response team
      - No coordination with the platform command
    - - Stability box left open
      - Man holes to aft star board ballast tank
      - No proper actions taken to stop the flooding
      - Continuous submersion of the platform
  - - - Lack of quality within the area of drained storage tanks
      - Designed drain tanks indoor and closed the support for sea water pipe used to help extinguish the fire created
        
        Major reason to the disaster
      - Sea firefighters presented a risk of flooding
      - 1,723 alarms were put of within 17 minutes of the incident
        
        No system placed for alarm entry and operation
      - Designed to be supported by the buoyancy of two pontoons and four support columns
        
        An emergency drain tank located in one of the columns was shutdown due to closure of valve
- - - - Due to high pressure the water pipe was removed and the valve was partially open
        
        Flooding distance from sea became shorter
  - - - Lack of engineering review on functions
- - - - Definition
        
        The function is performed with little work and power is provided by machine, the user controls it
  - - - Partially open
    - - Was left open
    - - Failure of watertight dampers
  - - - Were no used
- - - - Steel
      - Aluminum
      - Fiber-reinforced plastic
      - Polyethylene
    - - Engineers
  - - - Launching procedure
      - Carrying oil and gas
        
        High risk
      - Communicating system
