项目详情：

Barossa是一个海上油气和轻凝工程，由康菲石油澳大利亚勘探有限公司、Santos 离岸有限公司和SK E&S 澳大利亚有限公司共同组成的Barossa合资公司运营。待合适的商业布局落实到位时，该项目拟向现有的达尔文市液化天然气设施提供一个新的天然气来源。预计现有的海上天然气海上油田Bayu-Undan的供应将于2023年枯竭，因此该公司将用Barsossa对该供应进行补给。
该近海开发区位于北部地区达尔文以北300公里处的波拿巴盆地的联邦水域内。该区域包括油田保留石油租约NT/RL5和在未来有分阶段开发潜力，位于Caldita油田南部的油田保留租约NT/RL6。康菲石油公司持有许可证NTRL5和NTRL6的37.5%的权益，SK E&S享有37.5%，Santos享有25%。

2018年4月，Barossa进入前端工程设计开发阶段。在此阶段，成本和技术指标将最终确定，天然气和凝析油销售协议将取得进展，并与DLNG设施和Bayu-Darwin管道的所有者协商准入安排。

FPSO设施将把从气田中提取的天然气和冷凝物和干气将被通过出口管道分离并输送到岸上处理。凝析液将直接从FPSO输出到承购油轮。

新天然气出口管道长260-290公里，将按照已达成商业协议的约定条件，与现有的Bayu-Undan管道连接到位于联邦水域的达尔文管道。

主要项目合作的方法，如FPSO、海底、出口管道和钻井，将由澳大利亚康菲石油公司通过工程、设计采购和建设/安装(EPC/I)、租赁、直接签订合同和采购。

有限的采购活动在前端工程设计开发阶段预计会在最终投资决定之后出现。作为澳大利亚工业参与计划(AIP)的一部分，供应商/行业吹风会将在达尔文和珀斯进行，该计划已获得澳大利亚联邦政府的批准。

相关机会罗列如下：
1. 设计采购和建设/安装出口管道；
2. 光纤通信系统；
3. 天然气出口立管供应；
4. 生产和维护提升管供应；
5. 海底脐带缆、立管和流线(SURF)运输和安装(T&I)；
6. 出口管道的运输和安装；
7. 脐带缆系统。

 

Barossa Offshore

Locations: NT Australia
Project Value:> AUD $500 Million
Project Status: Front End Engineering and Design (FEED)
Project Owner: ConocoPhillips Australia Exploration Pty Ltd

Project Details
Barossa is an offshore gas and light condensate project being progressed by the Barossa Joint Venture comprising ConocoPhillips Australia Exploration Pty Ltd as Operator (ConocoPhillips Australia), Santos Offshore Pty Ltd and SK E&S Australia Pty Ltd.
The project proposes to provide a new source of gas to the existing Darwin LNG facility, subject to suitable commercial arrangements being put in place. It would backfill the facility from 2023 when the existing offshore gas supply from the Bayu-Undan offshore field is expected to be exhausted.

The offshore development area is located within Commonwealth waters of the Bonaparte Basin, about 300 km north of Darwin, Northern Territory. The area encompasses petroleum retention lease NT/RL5 and potential future phased development in the smaller Caldita Field to the south in petroleum retention lease NT/RL6. ConocoPhillips holds a 37.5% interest in permits NTRL5 and NTRL6, SK E&S (37.5%) and Santos (25%).

In April 2018 Barossa entered the front-end engineering and design (FEED) phase of development. During this phase, the costs and technical definition will be finalised, gas and condensate sales agreements progressed and access arrangements negotiated with the owners of the DLNG facility and Bayu-Darwin Pipeline.

The FPSO facility will separate the natural gas and condensate extracted from the field with the dry gas transported via the export pipeline for onshore processing. The condensate will be exported directly from the FPSO to offtake tankers.

The proposed new gas export pipeline will be 260-290 km long and would connect to the existing Bayu-Undan to Darwin pipeline in Commonwealth waters, subject to agreed commercial arrangements.

The procurement approach for major scopes, such as the FPSO, Subsea, Export Pipeline and Drilling, will be through a combination of Engineering, Procurement and Construction/Installation (EPC/I), leasing or direct contracting and procurement by ConocoPhillips Australia.

Limited procurement activity is expected during FEED with most expected to occur post-FID. Supplier/Industry briefings will be conducted in Darwin and Perth as part of the Australian Industry Participation (AIP) Plan for the Project, approved by the Commonwealth Government.

Opportunities are listed below.

1. EPCI of Export Pipeline
2. Fibre Optic Communication System
3. Gas Export Riser Supply
4. Production and Service Riser Supply
5. Subsea Umbilical, Riser and Flowline (SURF) Transportation and Installation (T&I)
6. Transport & Installation of Export Pipeline
7. Umbilical Supply
