Lights on, commissioning imminent at Ichthys LNG FPSO

Offshore staff

TOKYO – INPEX had provided an update on its Ichthys LNG project. The central processing facility (CPF) and FPSO safely started up their main power generators in the South Korean shipyards where they are being constructed. 

Last week at the Samsung Heavy Industries shipyard in Geoje, the CPF’s three generators run by 25 MW dual-fuel gas turbines energized the facility’s distribution network. 

The CPF milestone followed the July start-up of the FPSO’s main turbo-generators at the nearby Daewoo Shipbuilding & Marine Engineering yard in Okpo. 

Ichthys Project Managing Director Louis Bon said this achievement signaled commissioning was well under way for the two facilities. 

“Starting up the main generators of the FPSO and CPF allows the commissioning to further progress by providing the required power for both massive offshore facilities,” he said. 

Following the successful firing of the main power generation units, the focus will now be on load testing, synchronization, and commissioning of the power distribution systems for both offshore facilities. This will allow the permanent utilities on board each facility to be made fully available. 

The CPF and FPSO will be permanently moored for 40 years of operation in the Ichthys field, located in the Timor Sea about 220 km (137 mi) offshore Western Australia

Gas will undergo initial processing on the CPF to extract condensate and water and remove impurities in order to make the gas suitable for transmission. 

Most condensate will be transferred from the CPF to the nearby FPSO for offshore processing, with the remainder sent to Darwin with the gas via the project’s 890 km (553 mi) gas export pipeline.

More condensate will be extracted from the gas at the onshore plant in Darwin. Once in the field, the FPSO and CPF will be linked by an electric cable, allowing power supply to flow from each facility as a contingency measure as required.
