Abstract

ABB is running a joint project with Equinor, Total and Chevron to develop technologies for subsea power transmission, distribution and conversion. The output will form a critical part of future advanced subsea field developments. Started in 2013, the project reached a major milestone in late 2017 when the first full-scale prototype of the variable speed drive (VSD) passed a shallow water test. Final preparations are now underway for a 3000-hour test of the complete subsea power system with two VSDs in a parallel configuration combined with subsea switchgear and controls. The new solution will ultimately mean operators can free up topside space, or use no topside installation whatsoever, yielding significant cost and safety benefits. It is an extremely challenging endeavour, not only due to the harsh conditions to which the equipment will be subjected, but also because of the considerable reliability required. The equipment, the medium voltage (MV) switchgear, control and low voltage (LV) distribution equipment and the VSDs, must be able to run without intervention for many years. The VSD's successful shallow-water test is the subject of a separate OTC paper; here, we present the highlights in the context of the wider project and particularly the steps taken to build confidence along the way that the proposed solution will be fit for purpose when fully launched. Readers will gain insights into the key steps of this cutting-edge project. These include modifying prototypes of the equipment based on rounds of simulations, laboratory assessments (eg accelerated aging, vibration and shock testing) and water testing. As such an undertaking has never been achieved before, it is a journey with considerable learnings to be shared not only upon completion but also en-route. As we approach the goal which is anticipated by the end of 2019, it is appropriate to begin to share what we have learnt as we have been going the distance.

ABB海底电力JIP -走远
ABB正在与Equinor、Total和Chevron开展一个联合项目,开发海底电力传输、分配和转换技术。产量将成为未来先进海底油田开发的关键部分。该项目始于2013年,在2017年底达到了一个重要的里程碑,当时变速驱动器(VSD)的第一个全尺寸原型通过了浅水测试。目前正在进行的最后准备工作是对整个海底电力系统进行3000小时的测试,该系统采用两个并联配置的vsd,并结合海底开关设备和控制器。新的解决方案最终意味着作业者可以腾出上部空间,或者不使用任何上部装置,从而获得显著的成本和安全效益。这是一项极具挑战性的努力,不仅因为设备将受到恶劣的条件,而且还因为需要相当大的可靠性。设备,包括中压开关柜、控制和低压配电设备以及vsd,必须能够多年不受干扰地运行。VSD成功的浅水测试是另一篇OTC论文的主题;在此,我们将在更广泛的项目背景下介绍重点,特别是为建立信心而采取的步骤,即所提议的解决办法在全面启动时将适合目的。读者将深入了解这个前沿项目的关键步骤。其中包括根据模拟、实验室评估(如加速老化、振动和冲击测试)和水测试修改设备原型。由于这样的事业以前从未实现过,这是一段旅程,不仅在完成后,而且在途中,都可以分享大量的经验教训。随着我们接近预计到2019年底的目标,开始分享我们在这段时间里学到的东西是合适的。
