Jadestone Energy has completed installation of replacement subsea umbilical cables at the Montara complex, offshore Australia.
The umbilical cables are an essential part of the control system of the Montara complex subsea wells, providing electrical power and control signals to the subsea well-heads.
The replacement umbilical is expected to provide reliable operations for the remaining life of the field.
This project was identified by the previous operator PTTEP as a high priority, however the work was deferred until operatorship was transferred.
The replacement umbilical cables were installed using the DOF Subsea vessel Skandi Hercules, which was mobilized in Singapore in August, and completed work infield at Montara in September.
Paul Blakeley , president and CEO said: “I’m pleased to have completed this major capital project as the operator of Montara, safely, and on budget. Early on, we recognized the need to replace the control link to the Montara subsea wells, and this was done as soon as possible, following acceptance of Jadestone’s safety case for Montara. I think of this as a one-off maintenance project, and having it completed now will provide greater confidence in our ability to deliver guidance volumes from Montara.”
