DNV Launches Innovation Concept for Efficient Offshore Power Generation

Norwegian giant DNV gears up in investment in research and innovation every year.

In remote and ultra-deep waters, power generation for large field developments is demanding. By centralizing and sharing the power generation between several production units, the new DNV concept can reduce both emissions and costs.

Depending on how it is implemented, the cost saving may also be complemented by enhanced production capacity. The power generation arrangement may reduce CO2 emissions with approximately 40%.

The concept, Offshore Power system for a new era (OPera), provides several potential benefits for the connected units. The need for topisde processing power generation at each and every unit is eliminated, and available deck space can be increased. Significant increases in revenue could potentially be achieved with the installation of additional processing capabilities, resulting in more oil production from the same size installation.

With its centralized location, OPera allows improvements in operational logistics, by consolidating the location of power generation personnel, maintenance and spare parts.

How it works 

The power hub has a gas fired combined cycle power plant that increases power generation efficiency by more than 15%, compared with conventional gas turbines alone. By consolidating power generation, the power hub also allows equipment to run at more optimal load. This is a major benefit, as it further reduces fuel consumption and overall emissions. The power hub is fueled by associated gas or parts of the export gas produced.

Tailored to specific needs

The OPera power hub can be designed in different variants, and can also serve as a logistical hub, a centralized CO2 removal unit, or part of offshore LNG production.

The OPera concept is highly flexible in size and configuration, making it relevant for different types of fields. The power plant consists of modular gas and steam units of 50 and 100 MW capacities, allowing the combined capacity to be tailored.

Depending on water-depth, different platform and hull-designs can support the power plant. The power hub can connect with different numbers and types of installations.

Extraordinary innovation projects 

DNV invests 6-7 % of its revenue in research and innovation every year. While the majority is spent on long term research and development, the CEO directly finances a portfolio of extraordinary innovation projects. These projects are addressing immediate customer and industry needs, and serve as invitations to further collaboration with customers on their specific needs. The OPera project is only one of many such extraordinary innovations DNV contribute to the global oil and gas and maritime industries.
