2017年，挪威Optime Subea公司首席执行官Jan Fredrik Carlsen曾大胆承诺，将通过一项颠覆性的新技术，彻底改变水下油气行业的修井与控制能力。于是，Optime公司在2018的水下控制与修井轻型系统(SCILS)实现了这一承诺。Optime总部位于挪威Notodden，在美国德克萨斯州休斯顿设有分公司。它是一家小公司，专门研发创新解决方案，为客户的控制与修井作业节约成本。

Jan Fredrik Carlseni表示：“我们的目的不是为了颠覆行业，而是提供最新技术，来帮助行业实现降本增效。我坚信我们的SCILS能够发挥这样的作用。在油气行业中，我们发现了一个被忽视的领域，也许存在即是合理，但我们发现了它，就解决了它。目前我们推出了SCILS系统，这真的是最小、最具成本效益的采油树控制与修井系统。该系统类似于海底油井接入的修井完井系统(IWOCS)。然而，在3000米深的海底，目前没有其他系统能够在任何类型的采油树上进行作业。而且该系统体积小、质量轻，一辆小货车就能轻松完成运输。实际上，今年我们就是这样将SCILS系统运到了海底谷会议的会场。”

SCILS系统直径1.8米，高2.2米，重3吨。而传统IWOC系统在平台上配有一个20英尺的集装箱，以及一个大的绞盘与脐带缆，重约50吨。SCILS拥有如此苗条的身材，得益于其采用了Optime公司的水下泵，而不是利用平台的脐带缆输送水功率。

Jan Fredrik总结道：“与传统解决方案相比，SCIL系统可立即帮助作业者节省成本。该系统作业时仅需两道工序，而传统方法则需要6至8道工序。SCIL系统可以在一天内完成动复员，且安全性更高，而现如今的方法则需要数周时间。我们目前正着力于将SCILS用于现场作业，并实现任何类型的平台都能够部署该系统，以扩大我们的客户群体，抢夺常规系统的市场。凭借这些独门绝技，我相信我们会成为全球IWOC系统的首选供应商。我们花费数年时间开发了该技术，目的是为客户节约成本与时间。我们还可以帮助服务商、系统开发商、作业者，让他们成长为可靠的IWOC系统供应商。”

水下控制与修井轻型系统（SCILS）可简化任何类型平台上的井进入与修井作业。与传统的IWOC系统不同，SCILS系统能够在不增加复杂、重型设备的情况下，执行多个井控作业。该系统配备有一个闭环液压控制系统。将液压动力装置安装在海床上，则无需依靠大型设备，进而避免了冗长的交付周期，消除了可靠性风险与作业中的复杂性。与平台上传统的脐带缆系统相比，该系统的成本更为低廉。该系统拥有通用接口，且重量轻、体积小，避免了耗时的动复员。结合高效、增强的性能，SCILS系统最终可降低作业的资本支出与运营支出，从而惠及所有人。

可利用SCILS系统，可优化以下的油井安装与修井作业。包括海上平台的：1、采油树（XT）的安装，水下采油树的安装与功能测试；2、采油树的测试，安装海底采油树的后续测试与诊断；3、采油树与桥塞回收工具（PRT）的控制，安装水下采油树或桥塞回收作业时，控制采油树与桥塞回收工具；4、小型修井作业（LWI）的采油树控制，控制采油树，进行小型修井作业，包括：干预作业、注水泥塞弃井作业等；5、采油树水下控制模块的测试与诊断（SCM），仅需利用下行电缆；6、管汇控制与功能测试；7、油井增产作业。

SCILS规格

• 带有线轴的液压跨接管线滑橇：该滑橇配有线轴，可将16根液压跨接管线连接至采油树的接口。线轴能够容纳50米的管线，且受SCILS系统控制，可将跨接管线缠绕在线轴上。
• 带有线篮的液压跨接管线滑橇：该滑橇配有传统的采油树跨接线篮，可作为标准滑橇提供给SCILS系统。该滑橇还配有水下机器人仪表板，可安装任何第三方的MQC面板。
• 液压修井滑橇：该滑橇可用于油井增产作业。它与软管或连续油管连接，以便从平台上开展增产作业。该滑橇配有两个2寸的门阀，利用信号控制阀的打开与关闭。利用这种滑橇，SCILS系统就可控制安全阀，如果需要，还可以控制采油树。若客户有需求，可提供更大孔径的型号。

At Subsea Valley 2017, Jan-Fredrik Carlsen, CEO of the Notodden based Norwegian company Optime Subsea, boldly promised to revolutionize the intervention and controls segment of the subsea oil and gas industry through a new and disruptive technology

A year later at Subsea Valley 2018, the promise has been delivered by presenting Optime’s Subsea Controls and Intervention Light System (SCILS).

Optime Subsea AS (“Optime”) is headquartered in Notodden, Norway, with operations out of Houston Texas, USA. It is a smaller organization, specifically targeting innovative solutions that deliver cost-savings to customers in their niche controls and intervention market.

“Our intent is not to be disruptive for the sake of being disruptive, but support the industry’s progress in providing cost reducing tecnology. I believe our SCILS demonstrates this. We identified an area in the industry which was just neglected, perhaps for good reasons, but we identified it, solved it and now delivered on it. This is truly the smallest and most cost efficient tree control and intervention system available. The SCILS is similar to an Intervention Workover and Completion System (IWOCS) used for subsea well-access. There is however currently no other system capable of operating on any type of tree at 3000-meter depths, and yet small and light enough to be literally mobilized from the bed of a pickup truck, which was actually done when transporting the SCILS to the Subsea Valley conference this year,” says Jan-Fredrik Carlsen.

The SCILS measures 1.8 meters in diameter, 2.2 meters in height and weighs 3 metric tons. The traditional IWOC system comes with a 20-foot topside container and a large reel and umbilical, weighing approximately 50 metric tons. The size reduction of the SCILS is a result of transferring the hydraulic power subsea, using Optime’s subsea pumps, rather than through a topside umbilical.

“When compared to traditional solutions, the SCILS provides immediate cost savings for operators. We require 2 resources in operation, current systems need 6 to 8. Safety is increased and the SCILS can be mobilized and demobilized in a single day, in contrast to today’s solutions taking weeks. We are now in the process of getting the SCILS operational and with the ability of deploying this from any type of vessel, realize that our customer base increase substantially compared to current systems. With this unique solution, we do believe that we are going to be the preferred provider globally for IWOC systems. It is so cost efficient and built on technology which have taken years to develop, so that others don’t need to. We can support service providers, system developers and operators in being a reliable provider of IWOCS, ” Jan-Fredrik concludes.

The Subsea Controls & Intervention Light System (SCILS) designed to simplify well access, well interventions and work over operations from any type of vessel. Unlike traditional Installation Workover Control Systems (IWOCS), the SCILS is able to carry out multiple well control operations without adding complex and heavy equipment. The system comes with a closed loop hydraulic control system. The relocation of hydraulic power to the seabed eliminates the need for large equipment, long lead times, reliability challenges, complexity in operations and the high cost that may be found in traditional topside hydraulic umbilical systems. With a universal interface, light and small size, the SCILS removes the need for time consuming and costly mobilizations and demobilizations. Combined with a high efficiency and increased functionality, the SCILS ultimately delivers lower CAPEX and OPEX across the operations – benefiting everyone.

The following well installation and work over operations are all optimized through the use of SCILS: FROM VESSELS

• XT (“Christmas Tree”) Installation – Installation & functional testing of subsea
• XT Testing – Follow-on testing & diagnostics for installed subsea trees ? XT/PRT (Plug Retrieval Tool) Control – Control of the XT/PRT during VXT installation or PRT operations
• LWI (Light Well Intervention) XT Control – Control of the XT for LWI operations, including intervention and full P&A (Plugging & Abandonment)
• XT SCM (Subsea Control Module) Testing & Diagnostics – using electrical downline umbilical only
• Manifold Control & Functional Testing
• Hydraulic Intervention – Well stimulation

FROM RIGS

• XT installation – full testing capability
• XT Installation – Installation & functional testing of subsea trees, both HXT and VXT
• HXT Completion Control – Control of HXT’s during completion operations on HXT’s having no UDF (Umbilical Disconnect Function) on the BOP (Blow Out Preventer)
• XT control during completion (HXT systems, i.e. no UDF system on BOP)
• XT control during work operation, open water riser systems
