Question

Your fellow subsea engineer finally returns from her honeymoon dive trip, all tan and rested, talking incessantly about how great it was, etc. etc. While everyone is getting back up to speed on the subsea equipment and recent developments, you are notified that your pipeline permit documentation is not complete for the Red Hawk flowline for GB 877 Well 1 and you need to get the missing information to authorities right away, but the pipeline design company representative is not available.1) What information do you have and/or can be deduced about the Red Hawk flowline? Be as detailed as possible.2) From the information identified, specify what kind of pipeline it is, what the jurisdiction is and the associated permitting requirements?

Answer 1

1. a. Contingency plans

b. Route survey

c. Flowline service

d. Field topography

2. Flowline construction does not require oil pipeline licence.

Step-by-step explanation:

Deducible information includes;

1) The information available includes;

a. Location of subsea field

b. Location of wellhead to be connected

c. Flowline service; Gas, oil, water or condensate

d. Type of wellhead; Production or injection well

e. Flowline route survey documentation

f. Length of flowline < 1 km

g. Location of manifold

h. Location of third party facilities

i. Flowline construction plan

j. Contingency plan for environmental protection.

2). Type of pipeline is subsea flowline

Jurisdiction for flowline is

i. Limitation to 1 km length

ii. Infield use from wellhead to manifold and/or risers

iii. Survey of flowline route indicating the absence of third facilities

Flowline construction does not require oil pipeline construction licence.

Therefore only survey permit required

However a flowline route survey indicating that the flowline does not cross over third facilities including documentation will be sought.
