AKAL NW Flexible Riser Feasiblity Study
Year:
2023
Client:
PEMEX
Region:
GOM
Business Unit:
Subsea / Pipeline
DASH7 Ltd in collaboration with a local Mexico Engineering House is contracted by PEMEX to carry out a feasibility study to confirm utilisation of flexible export riser from the jack-up rig to the seabed interconnection.
Project Background
In supporting Pemex Exploration and Production's strategy to produce a new oil field as soon as possible, the Akal NW field was initiated as an early production project by PEMEX in October 2022.
Problem Definition
To expedite the production as soon as possible, a temporary export system is required to deliver the product from the AKAL 501/502/502S surface wells to the existing 36” L175 via hot tapping. Due to long lead time is required for the rigid riser fabrication (permanent), a temporary flexible riser solution has been adopted by PEMEX while waiting on the manufacturing of the rigid riser.
Scope of the Studies:
-
Feasibility study of flexible risers riser from jack-up
-
Flexible riser suitable catenary shape design
-
Topside connection/flange capacity check
-
Flexible on-bottom stability analysis
-
Flexible riser end fitting specification
