Granherne and Doris complete pre-FEED
The GDF Suez Bonaparte is a $3.7 to $4.6 billion Floating LNG project to liquefied the natural gas from the Petrel, Tern and Frigate fields in the Bonaparte Basin, in the Timor Sea, 250 kilometres west of the northern Australian city of Darwin.
GDF Suez Bonaparte is a joint venture created in 2009 with shared interests between:
- GDF Suez from France 60%
- Santos from Australia 40%
In January 2011, GDF SUEZ has awarded the contracts for pre‐Front End Engineering and Design (pre‐FEED) of the Bonaparte LNG project to:
- Granherne, a KBR company, for the upstream
- DORIS Engineering for the midstream
The project aims to produce between 2 and 3 million t/y of Liquefied Natural Gas (LNG).
From the pre‐FEED the FLNG should be 400 meters long and 70 meters wide.
In addition to the liquefaction units, the LNG trains, Bonaparte FLNG will also have the capability to produce, store and offload the condensates.
GDF Suez and Santos have also made the decsion to go for a purpose-built FLNG to be constructed in a shipyard of Asia Pacific.
The hull will be designed with a turret mooring system to remain connected in bad weather and adjust position to streams.
GDF Suez and Santos have estimated the capital expenditure of Bonaparte FLNG between $3.7 and $4.6 billion depending on the final capacity to be decided during the FEED.
The gas will be supplied to the Floating LNG from the seabed through 22 sub-sea wellheads in water about 100 meter deep.
With Bonaparte FLNG being positioned above the Petrel field, the gas sub-sea gathering system will include a 60 km sub-sea gas pipeline to connect the Tern and Frigate fields to the vessel.
GDF Suez linked bids on FEED and EPC contracts
With Granherne and Doris pre‐FEED coming to completion, GDF Suez and Santos worked on the short list for the Front End Engineering and Design (FEED) and engineering, procurement and construction (EPC) contracts.
From the long list of candidates which had applied for the pre-qualification, the competition for the FEED should be concentrated between:
- Chiyoda
- McDermott
- Saipem
- Technip
Each of these engineering companies will lead a consortium with a Korean contractors for the design of the hull and shipyard construction.
While bidding for the FEED contract, the engineering companies in competition will also have to submit a lump Sum Turn Key offer for the EPC contract.
If Shell has involved itself in every detail of its Prelude FLNG, GDF Suez and Santos have a different strategy and are planning to leave much more responsibility to the selected engineering company.
Therefore the winner between Chiyoda, McDermott, Saipem and Technip will have to assume it through this combination of FEED contract and lump Sum Turn Key EPC contract.

GDF Suez and Santos to make FID in 2014
GDF Suez is planning to execute the FEED in 2013 in parallel of signing the commercial agreement for the LNG in order to make the final investment decision (FID) in 2014.
According to this planning, GDF Suez and Santos expects the Bonaparte FLNG for completion and start operation in 2018.
