Sustainability

Our responsibility, as a world-leader in our industry, is to conduct our business sustainably and with the highest standards of business ethics and integrity.


In our efforts to build a sustainable Seadrill, we are focused on where we can make the biggest difference.

We are minimising the impact our activities have on the environment by developing advanced technologies to make our business ever safer and more efficient. Seadrill has reported into the Carbon Disclosure Project since 2012 and we are proud to be an industry-leader in terms of how we manage our carbon emissions and take coordinated action on climate issues.

At Seadrill, nothing is more important to us than the health, safety and wellbeing of our workforce and the communities in which we operate. Diversity and inclusion are more than words for us. Everyone is welcome—as an inclusive workplace, our people are comfortable bringing their authentic whole selves to work.

We continue to build an inclusive culture that encourages, supports, and celebrates the diverse voices of our people. It fuels our innovation and connects us closer to our customers and the communities we operate in.

Beyond complying with laws and regulations, we enforce a strong Code of Conduct and implement best practices to govern our operations. We also continuously refine our ethics and compliance policies, processes and training.

We believe that our commitment to sustainability will drive stakeholder value, we are dedicated to developing a business that is agile, resilient and sustainable in the long-term.

The world’s first hybrid offshore floater

The West Mira has become the first rig to operate as a hybrid power plant using a lithium-ion energy storage solution (ESS). As a result, it is also the first rig in the world to be awarded the DNV GL Battery (Power) class notation.

The advanced battery-based ESS was installed prior to the rig’s contract first, which began in November 2019, following close collaboration with Northern Ocean, Siemens, Kongsberg Maritime and DNV GL.

These batteries work by “taking the peaks” in periods of high-power requirements, which leads to reduced fuel consumption.

Siemens, provider of the battery system, estimates that it will reduce the runtime of the rig’s on-platform diesel engines by 42 percent, cutting CO2 emissions by 15 percent and NOx emissions by 12 percent. The system will also serve as back-up to prevent blackout situations and provide power to the thrusters in the unlikely event of loss of running machinery on affected switchboard segments.

Seadrill is managing the West Mira on behalf of Northern Ocean. The West Mira is an ultra-deepwater semi-submersible, operating a hybrid power plant using Lithium-ion batteries as spinning reserve in dynamic positioning (DP) operations and to supply power during peak-load times.

“We are proud to be the first rig contractor worldwide to have received DNV GL battery (power) class notation. By incorporating batteries, we can reduce the runtime of the diesel engines and maintain operations at an optimized combustion level, thereby increasing energy efficiency whilst lowering emissions.”

An advanced active emissions control technology system

The West Bollsta rig, managed by Seadrill and owned by Northern Ocean, is the first of its kind to utilise Selective Catalytic Reduction (“SCR”) technology in combination with a closed bus-tie notation system.

The combination of these innovative technologies significantly reduces carbon emissions from the West Bollsta, which started its first contract using SCR technology in May 2020.

The West Bollsta’s advanced emissions control technology system works by injecting urea into the exhaust stream of the diesel engine through a catalyst, where the nitrogen oxide (NOx) reacts with the urea and reduces it into nitrogen and water vapor.

The SCR technology works in conjunction with a closed bus-tie notation system to reduce fuel consumption on the rig as well as maintenance costs, minimising the rig’s overall carbon footprint.

As one of the most technologically-advanced semi-submersibles in Seadrill’s modern fleet, the West Bollsta is well-suited to implement the revolutionary combination of SCR technology and a closed bus-tie notation.

Seadrill worked closely with the Norwegian government to establish the industrial supply of urea in the volumes required by the rig. Specially sourced vessels delivered 300 metric tonnes of urea to the West Bollsta, allowing the rig to function in a cleaner, more environmentally-friendly manner.

Seadrill currently closely monitors and measures the carbon emissions output to track the advantages of utilising the combined technology.

“The combined installation of SCR technology and a closed bus-tie notation system on the West Bollsta is a revolutionary development for emission reduction in offshore drilling. With this development, Seadrill has again demonstrated its clear commitment to utilising advanced technology with the goal of reducing carbon emissions.”

An industry-leader in how we manage our carbon emissions and take action on climate issues

Monitoring, reporting and reducing our emissions is important to us, so we have reported our carbon emissions to the Carbon Disclosure Project (CDP) since 2012. We create minimum environmental standards for current and future suppliers and we conduct environmental impact assessments to identify potential environmental risks from our activities.

We report our carbon emissions not only to gain competitive advantage by getting ahead of regulatory and policy changes, but also to identify and tackle growing risks and find new opportunities for action being demanded by our investors and customers across the world.

In 2019, Seadrill improved its CDP rating to a ‘B’, meaning that for the second year running, we have been assessed by the CPD as “managing” our carbon emissions, and taking coordinated action on climate issues.

We have made substantial progress since we joined the CDP in 2012, and we are proud of the progress that we have made. Today, we report our scope 1, 2 and 3 emissions using our company reporting systems and service provider data.

Despite our recent progress in this area, we recognise that there is more that we can do. In future reports, we want to provide more detailed data around land transportation emissions, for example. And we will be able to provide detailed reporting on the impact of our hybrid battery system on the West Mira, on CO2 reduction on that rig.
