Weeks 11 & 12: Questions for $180!
« on: September 16, 2015, 02:39:32 AM »
1.   List 5 Differences between a PFD and a P&ID.

2.   In your opinion, what is the major difference between Positive Risks and Negative Risks?

3.   A company intends to introduce an additional production separator to their existing onshore production facility. The primary purpose is to increase production capacity from 12,000 BOPD to 20,000 BOPD. The existing plant have 3 installed 3-Phase Separators operating on 3-Phase modes. The highest process pressure possible in the plant is 485 Psig. The biggest challenge is that there is NO space in the facility to install the new separator on the grade. As an Engineer, list some checks you would make, to derive a practical solution to the challenge. Note that new separator has not been ordered and if your evaluations indicate opportunities to achieve the objective without the new vessel, it would be great value. Simply outline the basic evaluations or considerations you’ll undertake. You are not required to go into the detail of the task.

4.   Which of the following drawings/documents is used by various disciplines to define their tasks in the oil and gas process industry:
a.   Piping and Instrumentation Diagram(P&IDs)
b.   Electrical Single Line Diagram
c.   Structural Drawings for Foundations
d.   Block Flow Diagrams(BFD)
e.   Piping General Arrangement Drawings-GAs
f.   Piping Isometrics
g.   Cause and Effects Charts

5.   Which of the following would have the highest wall thickness value, if the same material is used in the fabrication/design calculations.
a.   ANSI 600 rated Pressure Vessel (Separator- vessel body – ASME Vessel Code
b.   ANSI 600 rated Process Piping/Fittings (Line Pipe)
c.   ANSI 600 rated Pipeline/Fittings (Line Pipe)
d.   ANSI 1500 rated Process Piping/Fittings (Line Pipe).
e.   ANSI 900 rated Process Piping/Fittings (Line Pipe)

6.   Which of the following tools can be used to carry out Hazard Identification for an offshore wellhead platform structural design
a.   Guide Word HAZOP
b.   Knowledge Based HAZOP
c.   Procedure HAZOP
d.   Job Hazard Analysis- JHA
e.   What-If Analysis

7.   Which of the following leak hole size gives the most demanding challenge to detection and response in an offshore oil facility located in high speed wind area?
a.   20mm
b.   50mm
c.   15mm
d.   Pin hole(less than 5mm)
e.   70mm
f.   35mm
