    NEWFOUNDLAND: The Net Zero Project & Electrification Possibilities Offshore

    The Net Zero Project is a collaboration within the energy and environmental industries to drive economic growth, diversification, investment, and awareness through the lens of sustainability and the pursuit of net zero in Newfoundland and Labrador’s energy sector.

    The Net Zero Project supports the development of clean growth strategies and projects in priority areas of Canada’s net zero journey as they relate to its offshore energy industry: carbon capture, utilization, and storage; electrification and renewable energy; and hydrogen.

    The Net Zero initiative includes a range of activities, such as:

    • Developing a roadmap for achieving net-zero emissions in Newfoundland and Labrador by 2050.
    • Establishing a network of organizations committed to the transition to a net-zero economy.
    • Conducting research and analysis to identify opportunities for reducing emissions and developing new technologies.
    • Providing training and support to businesses and organizations to help them reduce their carbon footprint.


    Aker Solutions is a market leader in both offshore greenfield and offshore brownfield electrification of oil
    and gas facilities through studies and projects in Norway, Scotland, Gulf of Mexico, Australia and Brazil.
    Aker has taken the learnings from these activities and applied them to potential developments offshore
    Newfoundland and Labrador.

    Offshore platforms typically generate electricity by burning fossil fuels to run onboard gas turbines and/or
    diesel-powered generating units. An alternative is to supply offshore installations with electricity from the
    mainland using a power cable transmission system.

    There are many benefits to utilizing power from the shore including reduced CO2 emissions, increased efficiency due to increased uptime of power system, increased safety due to reduction in possible sources of ignition and reduced planned maintenance and lower operating costs.

    Power can be connected from shore via alternating current (AC) or direct current (DC). For distances longer than 150 km, high voltage direct current (HVDC) has historically been used. The power transmission losses of the entire string do however always need to be considered from an overall perspective.

    Power from shore is widely used offshore Norway where sixteen fields constituting 45% of the countries’ oil and gas production will be connected to the shore by 2023 by both HVDC and AC cables. Similar to
    Newfoundland and Labrador, Norway’s electrical grid is predominantly powered by low GHG emitting
    hydroelectric power. This project aims to apply lessons learned from the Norwegian power from shore
    experience to future developments in the more challenging offshore environment of Newfoundland and

    Offshore developments in Norway are typically in 100-400m water depth, and generally within 150km of
    shore, whereas the potential development areas identified in this scope are in iceberg-prone locations more than 400km offshore and in water depths greater than 1200m. This water depth leads to floating solutions that have to be readily able to disconnect in the event of a potential iceberg impact. The only FPSO currently powered from shore in Norway is the permanently moored circular Goliat FPSO located in 400m of water and 100km offshore, in an area that is not prone to icebergs.


    Two potential greenfield power from shore development scenarios have been identified; a development in the West Orphan Basin with a point of interconnection (POI) at the Soldiers Pond station, and a potential development in the Labrador Sea with a POI at the Muskrat Falls generating station (See Figure 3-1: Potential Power From Shore Development Areas).

    Aker’s analysis indicates that electrifying new floating developments in these locations is challenging but feasible. These developments would be amongst the furthest from shore and deepest water electrification projects carried out to date.

    The most appropriate technology for these locations is low-frequency AC distribution with subsea transformers acting as distribution points to the FPSO. The diagrams below are a representation of the preferred LFAC approaches.

    The development of this initiative points toward the use of a Low-Frequency AC transmission and distribution system. This transmission technology will require less onboard space, reduced weight, and offer more flexibility in the electrical system design of the FPSO because major equipment, such as a gas compressor, can utilize the incoming 20Hz power and smaller converters and transformers can feed the remaining equipment as necessary.

    This will lead to reductions in regular maintenance, and increases in system uptime as the system does not require the maintenance or downtime associated with main power generation by onboard rotating machines.

    This system would require an onshore connection to the power grid and equipment to step down the voltage between 132kV and 145kV for subsea transmission. It also requires a subsea cable connected to a subsea transformer for distribution to multiple FPSOs, and to step down the power from the transmission voltage to 50-66kV, for use on each FPSO. It would also require dynamic cables from the sea bed to the FPSO, and will require the use of an electrical swivel if a ship-shaped FPSO concept is selected.

    30 years ago, Tina Olivero looked into the future and saw an opportunity to make a difference for her province and people. That difference came in the form of the oil and gas sector. Six years before there was even a drop of oil brought to the shores of Newfoundland, she founded The Oil and Gas Magazine (THE OGM) from a back room in her home on Signal Hill Road, in St. John’s, Newfoundland. A single mother, no financing, no previous journalism or oil and gas experience, she forged ahead, with a creative vision and one heck of a heaping dose of sheer determination. With her pioneering spirit, Ms. Olivero developed a magazine that would educate, inspire, motivate and entertain oil and gas readers around the world — She prides herself in marketing and promoting our province and resources in unprecedented ways. The OGM is a magazine that focuses on our projects, our people, our opportunities and ultimately becomes the bridge to new energy outcomes and a sustainable new energy world. Now diversifying into the communications realms, a natural progression from the Magazine, The OGM now offers an entirely new division - Oil & Gas Media. Today, The Oil and Gas Magazine is a global phenomenon that operates not only in Newfoundland, but also in Calgary and is read by oil and gas enthusiasts in Norway, Aberdeen, across the US and as far reaching as Abu Dhabi, in the Middle East. Believing that Energy is everyone’s business, Ms. Olivero has combined energy + culture to embrace the worlds commitment to a balance of work and home life as well as fostering a foundation for health and well being. In this era of growth and development business and lifestyle are an eloquent mix, there is no beginning or end. Partnering with over 90 oil and gas exhibitions and conferences around the world, Ms. Olivero's role as a Global Visionary is to embrace communication in a way that fosters oil and gas business and industry growth in new and creative ways.
