Australian contractor Worley has confirmed that it is participating in the dual front-end engineering and design (FEED) competition alongside lead contracting partner Malaysia Marine & Heavy Engineering (MMHE) for Petronas’ Kasawari carbon capture and storage project offshore Malaysia.

Malaysian subsidiary Ranhill Utilities formally announced its very own Perunding Ranhill Worley (PRW) had been awarded FEED work for Petronas’ Kasawari CCS project (Kasawari phase two).

The workscope of the 18 million ringgit (US$4.04 million) contract includes the carbon dioxide technology specification, evaluation and selection, along with design and engineering development for the platform, jacket, bridge and pipeline.

The PRW team's focus is on development of “a well thought-out design solution” that meets safety, operability and maintainability requirements while driving for reduced total installed cost. The design will be enhanced through use of a digital-driven systems and tools, said the contractor.

Kasawari is being hailed as the world’s largest offshore CCS project, which will capture 3 million tonnes per annum of CO2, although this could be eclipsed by Santos' considered Bayu-Undan CCS that is touted with 10 million tpa capacity.

The new Kasawari CCS platform will be bridge-linked to Kasawari central processing platform, that is the cornerstone facility for the main Kasawari field development.

The CO2 will be transported by a 138-kilometre 16-inch diameter subsea pipeline and injected into a depleted offshore gas reservoir at the offshore M1 field.

MMHE and PRW are going head-to-head with the pairing of National Petroleum Construction Company and Technip Energies as its engineering partner for the parallel paid-for FEED work.

The duration of the FEED work is seven months with Petronas to choose the winning partnership at the end of the year.

“If we are successful with our partner MMHE, detailed design would commence in early 2023,” Ranhill Utilities said in an announcement to Bursa Malaysia (the Malaysian stock exchange).

“It is anticipated that even with the most aggressive projections of renewable energy transition, there will still be need for hydrocarbons to be part of the energy mix. Therefore, moving forward, CCS will be a key part of global transition to net zero carbon emissions,” added the contractor.

“We are committed to working together with our customers to navigate their energy transition process to decarbonise the extraction of hydrocarbons.”

PRW's Letter of Award was dated 16 February, but Ranhill only got the green light earlier this week from Petronas and FEED partner MMHE to announce its contract win.
