Woodside awards Julimar Phase 3 subsea EPCI to TechnipFMC

Woodside Energy Julimar Pty. Ltd. has awarded TechnipFMC a contract to engineer, procure, construct, and install (EPCI) flexible pipes and umbilicals for its Julimar Phase 3 development, offshore Western Australia.

Under the contract, TechnipFMC will tie back four subsea gas wells in Carnarvon basin to existing Julimar subsea infrastructure producing to the Chevron Corp.-operated Wheatstone platform, using high-pressure, high-temperature (HPHT) flexible pipe and steel tube umbilicals. Woodside expects these activities to start between third-quarter 2024 and second-quarter 2025, subject to approval.

Woodside plans to drill up to four wells (JUA1C, JUA1E, JUB1A and J-85 development well) in Julimar field and one well (JUB1B) in the Penfolds prospect in permit area WA-49-L. The wells are at a water depth of 120-210 m. The Julimar production system is anticipated to have a design life of around 25 years.

Project activities include connection of two wells (JUB1B and JUB1A) to a new two-slot production manifold (JULB). The manifold will tie into the existing in-line tee assembly via 2.5 km of flexible flowline and umbilical. JUB1B will connect to the new JULB manifold by a 4.4 km flexible flowline and umbilical. Three wells (JUA1C, JUA1E, and J-85 development well) are planned to tie back to empty slots at the existing JULA production manifold via flexible flowlines and umbilicals.

Activities will occur predominantly within the WA-49-L title area with some overlap with neighboring Chevron-operated title areas WA-5-R, WA-76-R, and WA-526-P. The proposed activity will be performed by either a moored semi-submersible mobile offshore drilling unit (MODU), dynamically positioned (DP) MODU, or a hybrid MODU which will moor on the seabed and operate on DP assist mode. Start-up and operation of the Julimar Phase 3 production system will be subject to approval of a future revision of the Julimar Operations Environment Plan.

Julimar joint-venture participants are Woodside (65%) and Kuwait Foreign Petroleum Exploration Co. KSE Australia (Julimar) Pty. Ltd. (35%).
