“…The Valhall field case study presented in [29] and reviewed in [30] is also based on HVDC-VSC and shares the same design considerations as Troll, such as the modular and highly compact design installed directly on the offshore platform. After five years of operation, the system was deemed as having an "excellent performance".…”

Standardization of Power-from-Shore Grid Connections for Offshore Oil & Gas Production

Offshore oil and gas (O&G) production is typically powered by local diesel engines or gas turbines. Power-from-shore (PFS) is an alternative that takes advantage of onshore renewable production and reduces greenhouse emissions but is limited to bespoke projects that are tailored to the characteristics of each site. This lack of repetition leads to an increase in the construction risk, delivery time, and lifecycle costs, therefore limiting their large-scale deployment. Furthermore, the absence of standardized designs is also notorious in mature applications such as offshore wind farms (OWF) despite their long-standing track record, with the negative consequences extensively covered in the literature. This research paper addresses offshore transmission standardization in two parts. First, by providing the scientific community with a review of the existing offshore O&G production and substations and secondly, by outlining a lean optioneering algorithm for the cost-optimized and technically feasible selection of the key design criteria. The exercise is centred on the main limiting component of the transmission systems—the cables. As such, it addresses their operational range and the cost to calculate the most effective configuration in terms of voltage and rated power. The end goal, based on the spread of connection proposals, is to cluster the candidates to a limited set of grid connection options, the achievement of which the model has been shown to be adequate.

“…To achieve ambitious sustainable goals regarding electric power production, Europe aims to integrate high amounts of offshore wind power in the North Sea to England, France, Germany and Norway. Moreover, offshore O&G production units could receive electric power from the shore, lowering the emissions in their production, as O&G are still expected to play a major role in the energy transition [23][24][25]. In the South, the European grid could be interconnected to Northern Africa to integrate the production of high levels of solar power.…”

A Review on Multi-Terminal High Voltage Direct Current Networks for Wind Power Integration

With the growing pressure to substitute fossil fuel-based generation, Renewable Energy Sources (RES) have become one of the main solutions from the power sector in the fight against climate change. Offshore wind farms, for example, are an interesting alternative to increase renewable power production, but they represent a challenge when being interconnected to the grid, since new installations are being pushed further off the coast due to noise and visual pollution restrictions. In this context, Multi-Terminal High Voltage Direct Current (MT-HVDC) networks are the most preferred technology for this purpose and for onshore grid reinforcements. They also enable the delivery of power from the shore to offshore Oil and Gas (O&G) production platforms, which can help lower the emissions in the transition away from fossil fuels. In this work, we review relevant aspects of the operation and control of MT-HVDC networks for wind power integration. The review approaches topics such as the main characteristics of MT-HVDC projects under discussion/commissioned around the world, rising challenges in the control and the operation of MT-HVDC networks and the modeling and the control of the Modular Multilevel Converter (MMC) stations. To illustrate the challenges on designing the control system of a MT-HVDC network and to corroborate the technical discussions, a simulation of a three-terminal MT-HVDC network integrating wind power generation and offshore O&G production units to the onshore grid is performed in Matlab’s Simscape Electrical toolbox. The results highlight the main differences between two alternatives to design the control system for an MT-HVDC network.

“…The estimated financial loss for incidents due to poor power quality in the O&G sector is 250,000-750,000 euros per day [68]. In order to increase the energy efficiency and reduce the CO 2 and NO x emissions, several platforms have been recently electrified, using either High-Voltage Alternating Current (HVAC) [70], [71] or High-Voltage Direct Current (HVDC) [72], depending on their power demand and distance from shore [73]. Among the advantages of "power-from-shore" solutions, in addition to high efficiency, there are high availability (~ 99%) and systems lifetime (~ 30 years), as well as reduced maintenance needs and repair time [74].…”

The main goal of this paper is to outline characteristics and critical aspects related to the design and operation of offshore and subsea electric distribution grids, particularly in the case of high penetration of distributed and intermittent renewable energy sources. At first, the paper provides an overview of electric loads operating in the ocean environment, surveys their power and energy demands and presents their main operational characteristics and corresponding maturity of technology. Subsequently, the potential of marine renewable energy sources is identified by analyzing their degree of development, typical power range and suitability to supply the offshore loads. Based on an up-to-date review of previous studies and real test cases, this paper shows how conditions to enable the development of "offshore smart grids" can be met and it outlines emerging trends in the electrification of the ocean space.Index Terms-Deep-sea mining, marine energy, offshore grids, offshore wind, oil and gas platforms, subsea applications.
