据Oil & Gas Journal网站5月10日墨尔本报道：加拿大兰万灵公司（SNC Lavalin）已经签署了两份分包合同，以支持伍德赛德石油集团在西澳大利亚埃克斯茅斯高原的斯卡伯勒气田开发计划。
加拿大兰万灵公司将为半潜式船体和系泊系统提供前端工程设计支持，以及模型测试范围鉴定、监督和相关辅助范围鉴定。
公司还将提供全面的技术安全、安全评估和风险工程服务，以支持斯卡伯勒的工程设计活动。
这两份合同将涉及该公司在休斯顿的离岸工程子公司及其在西澳大利亚的阿特金斯公司的业务。
这两个范围的鉴定都有一个扩展至详细设计工程的选择，计划将在2020年作出斯卡伯勒项目的最终投资决定。
斯卡伯勒气田位于巴鲁普半岛西北偏西375公里处。该计划将有七口海底气井生产高达3亿标准立方英尺/日的天然气，并将其输送回配备有天然气压缩和水处理设施的半潜式FPU，并能够连接未来所需要的设施。该设施将停泊在靠近气田900米的水中。
脱水后的天然气将通过一条430千米长的管道送至岸边，然后输送至伍德赛德运营的Pluto海上平台，再通过一条与现有Pluto管道相连的复式干线输至巴鲁普半岛上的Pluto陆上液化天然气设施。
斯卡伯勒气田储层的孔隙度为30%，渗透率为1600毫达西。该气田估计拥有2C级资源量为7.3万亿立方英尺的天然气，由96%的甲烷和4%的氮气组成，同时含有50ppm的二氧化碳。

Woodside lets contact for Scarborough development
Two subcontracts to support development of the floating production unit SNC Lavalin is to provide front-end engineering design support for the semisubmersible hull and mooring system as well as model testing scoping and supervision and ancillary scopes.
The company also will provide overall technical safety, formal safety assessment, and risk engineering services to support the engineering design activities for Scarborough.
The two contracts will be run out of the company’s Houston offshore engineering subsidiary and its Atkins business in Western Australia.
Both scopes have an option to extend to detailed design engineering subject to the Scarborough joint venture reaching a final investment decision for the project, which is scheduled for 2020.
Scarborough field is 375 km west-northwest of the Burrup Peninsula. The plan is to have seven subsea gas wells producing as much as 300 MMcfd of gas and tied back to a semisubmersible FPU fitted with gas compression and water-handling facilities and be capable of accepting future tie-ins. It would be moored in 900 m of water close to the field.
The dewatered gas would be sent to shore via a 430-km pipeline that would be laid first to the Woodside-operated Pluto offshore platform and then Scarborough field reservoir has a porosity of 30% and a permeability of 1,600 md. The field has an estimated 2C resource of 7.3 tcf of gas, composed of 96% methane and 4% nitrogen and contains 50 ppm of carbon dioxide.
