“…In the past decades, significant technological advances have enabled long-distance tiebacks for development projects. Some recent technological advancements include Davalath & Wiles (2017), Gassert et al (2019), Mikalsen & Loper (2019), Wiles et al (2019), Rajaratnam et al (2020), and (Bacati et al 2020), but will not be further elaborated on here. Karimaie et al (2018) provided a technical evaluation of the feasible development concepts for selected oil discoveries in the Barents Sea; Goliat, Johan Castberg, Alta, Gohta, and Wisting.…”

“…These converters allow for the optimization of power flow between generators and loads, wich is used in applications of smart electrical installations [24], [25]. Particularly, with the recent exploration of deep-sea oil reserves, FPSO units stand out as a relevant application for the use of VFDs, which can improve the energy efficiency of the power system in these installations [26]- [29].…”

With the current utilization of Floating, Production, Storage, and Offloading (FPSO) units by the petroleum industry, and the trend towards optimizing the energy efficiency of electrical systems, Variable Frequency Drives (VFDs) play a crucial role in enhancing the performance and power quality (PQ) of the power system on these offshore platforms. The FPSO unit operates in various modes, depending on its regular activities, such as contingency, production and offloading. Each operating mode has multiple grid configurations with different generation and load connections, including the contingency mode that is used for planned maintenance or failure in one of the aeroderivative gas turbine generators (GTGs). During the contingency mode, the FPSO unit runs with two GTGs and implements load shedding. Therefore, this paper investigates a specific case of the contingency operating mode, considering scenarios with zero, one, two, and three VFDs connected to the largest motors. Additionally, it analyzes VFDs with both passive and active frontend rectifiers, aiming to minimize the number of loads to be shed during contingency. The main result shows that by using the active front-end VFDs, 14.3 MW of loads that would be shut down during contingency mode can continue to operate.INDEX TERMS Energy efficiency, oil and gas platform, power factor, reactive power control, variable frequency drives.

Offshore industry has about three decades of experience with the development and deployment of floating and subsea technologies in deep (> 500 m) and ultra-deep (> 1,500 m) waters. Most of the ultra-deep water experience has been gained from fields in the Gulf of Mexico, Brazil, and West of Africa. Significant exploration and development activities undergoing in deep and ultra-deep waters of more than eight South American countries require low cost solutions to enable their development. This Panel will present and discuss the innovative initiatives undertaken by the industry for further development of solutions and technologies for deepwater production facilities (floating and subsea units, risers, umbilicals, flowlines and pipelines) to reduce their capital and operating costs. The innovative initiatives range from variations in the design and execution plans to qualification of specific new technologies. The digitalization of these facilities is also providing means to further reduce capital and operating costs and enhance productivity, safety, and reduce environmental impact. In addition, the potential value from renewable energy to subsea and field operations is being evaluated. These initiatives are in various stages of development and some are being implemented in deepwater fields in Brazil and Guyana. Several of these innovative technology initiatives will go from Technology Readiness Level (TRL) 5 to 7 in South American fields after operating for more than 3 years.
