摘要

2016年,Subsea Integration Alliance (SIA)获得了业界首个深水一体化海底工程、采购、施工、安装和调试(EPCIC)多相增压系统合同。该合同要求在墨西哥湾的Dalmatian油田提供和安装海底多相增压系统,这是世界上最长的深水海底增压回接。为了提高石油采收率(IOR),进行了几项研究,海底增压可以产生最佳的经济效益和最低的总体风险。海底增压系统现已安装完毕,并显著提高了作业者的最终采收率。Dalmatian油田由Murphy及其合作伙伴在墨西哥湾深水区开发,并于2014年4月投产。该油田是在水深约6000英尺的海底进行回接的,在水深约1800英尺的浅水区,与Petronius油田标准的塔台的回接距离达到了创纪录的22英里。海底油田提高采收率的挑战推动了海底处理技术的进步,特别是在海底提升领域。海底多相增压系统在全球范围内的成功运行,以及这些系统产生的巨大附加价值,推动了技术的进步,包括更高的压差和更长的步距。海底增压系统于2018年10月安装,显著提高了作业者的最终采收率。通过与运营公司的密切合作,SIA已经证明,这种类型的项目执行,也被称为供应商主导的解决方案(SLS),可以有效地加速项目完成,降低进度和安装风险,并提高整体项目经济性。从合同签订到泵启动,该项目在不到23个月的时间内完成。这是通过使用成熟的技术和新颖的集成合同模型来实现的。此外,还进行了前端工程设计(FEED)研究,以确定项目范围,包括集成资产建模,以充分探索系统的潜力,使项目得以批准。Dalmatian海底增压系统代表了海底处理领域的游戏规则改变者,因为它是提高采收率和实现长时间深水回接的重要飞跃。对于偏远、深井和恶劣环境的油田开发,该技术是关键的推动因素。本文解释了海底增压系统在达尔马提亚油田的应用,并讨论了联盟的SLS方法如何在现有设计的基础上使用适合用途的解决方案来交付项目,确保了运营商深水增压系统的无缝交付和安装。

Dalmatian Subsea Boosting: Project Execution and Early Operational Experience from the First High-Boost Multiphase Boosting System Deployed in the Gulf of Mexico
In 2016 the Subsea Integration Alliance (SIA) was awarded the industry's first deepwater integrated subsea engineering, procurement, construction, installation, and commissioning (EPCIC) multiphase boosting system contract. The scope of the contract called for the supply and installation of a subsea multiphase boosting system in the Dalmatian Field in the Gulf of Mexico and represents the world's longest deepwater subsea boosting tieback. Several studies were conducted to look at increased oil recovery (IOR), with subsea boosting yielding the best economic benefits and lowest overall risk profile. The subsea boosting system has now been installed and has significantly improved the operator's ultimate recovery. The Dalmatian Field was developed in deepwater Gulf of Mexico by Murphy and partners and commenced production in April 2014. The field was developed as a subsea tieback in water depths of approximately 6,000 ft, with a record tieback distance of 22 mi to the Petronius Field compliant tower platform in shallower waters of approximately 1,800 ft. The challenge of increased recovery in subsea fields has driven the advancement of subsea processing technologies, especially in the subsea boosting domain. The successful operation of subsea multiphase boosting systems on a global scale, coupled with the significant added value these systems generate, has driven technological advances in terms of higher differential pressures and longer step-outs. The subsea boosting system was installed in October 2018 and significantly improving the operator's ultimate recovery. Working in close collaboration with the operating company, the SIA has demonstrated that this type of project execution, also referred to as a supplier-led-solution (SLS), can be an effective way to accelerate project completion, reduce schedule and installation risk, and improve overall project economics. This project was completed in a very short execution time of less than 23 months from contract award to pump startup. This was achieved using mature technology in combination with a novel integrated contract model. In addition, a front-end engineering design (FEED) study was performed to define the project scope that included integrated asset modeling to fully explore the potential of the system that enabled the project to be sanctioned. The Dalmatian subsea boosting system represents a game changer in the subsea processing domain because it is an important leap forward in the efforts to improve recovery and enable long deepwater tiebacks. For field developments in remote, deep, and hostile locations, this technology represents a key enabler. This paper explains the application of the subsea boosting system in the Dalmatian Field and discusses how the Alliance's SLS approach to project delivery using fit-for-purpose solutions based on existing design ensured a seamless delivery and installation of a deepwater boosting system for the operator.
