GDF-Suez and Santos to award Bonaparte FLNG FEED on Q1 2014

Australia Bonaparte FLNG to start operations in 2019

The French energy group GDF-Suez and its Australian partner Santos Ltd (Santos) are planning to award the front end engineering and design (FEED) contract on the first quarter 2014 for the development of the Bonaparte floating liquefied natural gas (FLNG) to be moored offshore Western Australia.

This contract was expected to be sanctioned earlier in 2013, but this innovative project required GDF-Suez and Santos to extend to further details the ongoing competitive pre-front end engineering and design (pre-FEED) due to lead to the FEED contract.

 – GDF-Suez 60% is the operator

 – Santos 40%

This Bonaparte FLNG is planned to be moored in the Timor Sea to develop three natural gas fields Petrel, Frigate and Tern located approximately 230 kilometers west of Darwin by 100 meters of water depth.

Since GDF-Suez and Santos rely on the engineering companies technologies to design and build this first FLNG for their fleet, the qualification of the processes and performances goes step by step and takes a lot of attention and time.

This process started in January 2011 when GDF-Suez and Santos awarded Granherm, from KBR, and Doris Engineering (Doris) to perform the conceptual studies.

Granherme was in charge of the upstream part of Bonaparte project and Doris of the midstream portion.

From this conceptual study, the Bonaparte FLNG took the shape of a vessel 400 meters long and 70 meters wide.

KBR and Technip to compete on Bonaparte FEED

While GranhermKBR and Doris were performing the Bonaparte FLNG conceptual studies, GDF-Suez and Santos decided to organize a pre-FEED competition in order to evaluate the different technologies available on the market at this still early age of the FLNG solution.

After a pre-qualification process initiated in June 2012, GDF-Suez and Santos signed pre-FEED agreements with KBR, previously involved in the conceptual study, and Technip already building FLNG vessels for Shell and Petronas.

This hull should support a permanently connected mooring system that would continuously align the vessel on streams and winds.

In May 2013, GDF-Suez and Santos selected JP Kenny from the Wood Group to perform the pre-FEED on the subsea package to operate 22 subsea wellheads.

Since the Bonaparte FLNG should be moored above the Petrel gas fields, the subsea system will require 60 kilometers of pipelines to gather the natural gas from the Frigate and Tern fields located further southwest.

To compete in this pre-FEED, KBR and Technip partner respectively Hyundai Heavy Industries (HHI) and Daewoo Shipbuilding and Marine Engineering (DSME).

Since the tandem KBRHHI and TechnipDSME have completed their pre-FEED work, GDF-Suez and Santos are planning to award the FEED contract on early 2014 for a final investment decision (FID) and signature of the engineering, procurement and construction (EPC) contract in 2015 in order to put the Bonaparte FLNG on stream by 2019.

  1. Thank you for the auspicious writeup. It
    if truth be told was a leisure account it. Glance complex to far brought agreeable from you!
    However, how can we keep up a correspondence?
