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
