MODEC, Inc. ("MODEC") is pleased to announce that its subsidiary, MODEC International Inc., has been awarded a contract by ConocoPhillips Australia, as operator of the Barossa joint venture, for the Front End Engineering Design (FEED) of a Floating Production Storage and Offloading (FPSO) vessel for Australian waters.
Under the contract, MODEC shall participate in the FEED on a competitive basis against a JV of two other contractors. Barossa is an offshore gas and light condensate project that proposes to provide a new source of gas to the existing Darwin LNG facility. The offshore development concept includes subsea production system and gas export pipeline as well as the FPSO, located approximately 300 kilometers north of Darwin, Australia.
MODEC has an excellent track record of Engineering, Procurement and Construction (EPC) projects of delivering five (5) FPSOs in Australia, five (5) of which MODEC operated for a total of 42 years.
The Barossa joint venturers are ConocoPhillips Australia Barossa Pty Ltd (operator, 37.5%), SK E&S Australia Pty Ltd (37.5%) and Santos Offshore Pty Ltd (25.0%).
MODEC Awarded Contract to Supply FPSO for Barossa Field offshore Australia by ConocoPhillips
Tokyo, October 30, 2019
MODEC, Inc. ("MODEC") is pleased to announce that it has signed a contract with ConocoPhillips Australia Barossa Pty Ltd to supply a Floating Production Storage and Offloading (FPSO) vessel for the Barossa field, offshore Australia. The Barossa FPSO is intended to produce gas and condensate from subsea wells and after treatment, supply feed gas to the Darwin LNG Plant via a gas export pipeline.
MODEC was awarded a Front End Engineering Design (FEED) contract of the Barossa FPSO in June 2018 and has now been selected as the turnkey contractor based upon its successful performance and deliverables of the FEED contract.
The Barossa FPSO is MODEC's largest size of "Gas FPSO" to date, which will be able to export over 600 million standard cubic feet of gas per day as well as store up to 650,000 barrels of condensate for export. It has been designed to withstand a 100-year cyclone event at a water depth of 260 meters and located some 300 kilometers off north of Darwin, Australia.
MODEC will be responsible for the Engineering, Procurement, Construction and Installation (EPCI) of the Barossa FPSO, including topsides processing equipment as well as hull and marine systems. Scheduled for delivery during 2023, the FPSO will be permanently moored by an internal turret mooring system supplied by a MODEC group company, SOFEC, Inc.
The Barossa FPSO will be the first application of MODEC's "M350 Hull", a next generation new built hull for FPSOs, full double hull design which has been developed to accommodate larger topsides and larger storage capacity than conventional VLCC tankers, with a longer design service life of 25 years and beyond. The hull will be built by Dalian Shipbuilding Industry Co., Ltd. (DSIC) in Dalian, China.
The FPSO features a boiler and steam turbine based power generation system instead of conventional gas turbines, which helps reduce the carbon dioxide footprint of the facility.
"We are extremely honored and proud to have been selected to provide the Gas FPSO for Barossa project," commented Yuji Kozai, President and CEO of MODEC. "This contract award of a Gas FPSO reinforces one of our important business strategies, which we aim to penetrate into gas-related market. Also this new contract represents a significant milestone for MODEC in applying our next generation new built FPSO hull design of which we have developed to meet the new market demands for larger FPSOs. We are equally pleased to be a part of the team that will provide natural gas, a major clean energy source, for the benefit of the people and environment."
The Barossa FPSO will be MODEC's 6th FPSO in Australia and this contract award confirms its advanced position as the leading FPSO service provider in the country.
The Barossa joint venture is currently formed by ConocoPhillips Australia Barossa Pty Ltd (field operator, 37.5%), SK E&S Australia Pty Ltd (37.5%) and Santos Offshore Pty Ltd (25.0%).

The offshore development concept includes a Floating Production Storage and Offloading (FPSO) facility, subsea production system, supporting subsea infrastructure and gas export pipeline, all located in Commonwealth waters about 300 kilometres northnorthwest of Darwin.
The DLNG infrastructure owners are currently assessing options to backfill the facility’s existing LNG train from 2023 when the current gas supply from the Bayu-Undan offshore field is expected to be exhausted.
If Barossa is selected as the DLNG backfill option, it would enable continued operation of the DLNG facility for a further 20 plus years. In addition to meeting future global demand for natural gas, the Barossa Project would contribute significant income, employment and other benefits to the Northern Territory and Australia.
In April 2018, Barossa entered the Front-End Engineering Design (FEED) phase of development which will continue until approximately the end of 2019. During the FEED phase, the costs and technical definition for the project will be matured, LNG and condensate sales agreements progressed, and access arrangements negotiated with the owners of the DLNG facility and BayuUndan pipeline to Darwin.
The major FEED contracts for the FPSO, subsea infrastructure and gas export pipeline have been awarded. A Final Investment Decision (FID) on the project would be made following the FEED phase.
The Barossa Project area encompasses petroleum retention lease NT/RL5 (the Barossa Field), where initial development would occur, and potential future phased development in the smaller Caldita Field to the south in retention lease NT/RL6.
The development concept notionally involves drilling 10 subsea wells in two phases. The subsea production gathering system lies on the ocean floor at a water depth of approximately 250 metres.
Gas and condensate would be gathered from the wells by the subsea production system and then brought to the FPSO via a network of subsea flowlines and risers.
Initial processing to separate the gas, water and condensate extracted from the field would then occur on the FPSO.
Condensate would be transferred from the FPSO to specialised tankers for export. Gas would be exported to DLNG via a new 260 km export pipeline tied into the existing Bayu-Undan to Darwin pipeline about 100 km from Darwin, subject to access arrangements being negotiated with existing infrastructure owners.
The exact route of the new pipeline from the Barossa Field is not final and is subject to further studies, but would be located in the gas export pipeline corridor as outlined in the map above.
