Technip FMC Deepwater flying lead

Project Scope of Work

ENI Maura Bakau operate the Jangkrik (JKK) complex and the Jangkrik North East complex (JKKNE) fields that has a subsea production system incorporating a total of 12 wells, 5 PLEMS,  and a series of umbilical’s and flexible lines that feed to a moored FSU that processes and exports gas through a 24” line and 4” Condensate line to shore.

Technip FMC as the installers of the original SPS have requirement to ensure ongoing operability. The system operates in water depths of 200m to 500m and the scope of work comprised two phases:

Replacement of HFL-H1 in JKK Main 1 Cluster

  • HFL – H1 disconnected from JKK Main 1 UTH and SDU 1 before replacing with the new HFL-H1.
  • EFL – E1S and EFL – E2S at JKK Main 1 UTH to be disconnected and temporarily parked at JKK Main 1 Cluster area at CPI ROV Work Basket.

Trouble shooting – connect disconnect EFLs at:

  • Deep water HV EFL 80m
  • Replacement of HV EFL EC-1

Project Summary

A technically complex project to both replace a flying lead through ROV intervention at nearly 400m water depth, and perform further fault finding and general rectification, relocation and stabilization of the flying lead. Shelfs engineering team ensured the work was completed smoothly and without issues.

Performed at the peak of the COVID outbreak the Project Management team organised an extremely complex mobilisation and demobilization.
