DNV and Altera Infrastructure test notation to reduce emissions in offshore installations

DNV introduced a new class notation, Abate, designed to help owners and operators of offshore floating facilities identify and implement measures to reduce greenhouse gas (GHG) emissions.

Altera Infrastructure, the first company to adopt the solution, has incorporated the notation into the FPSO “Petrojarl Knarr”, with successful results so far.

The International Maritime Organization (IMO) is setting targets for the decarbonization of the maritime industry. Offshore installations are not yet covered by international requirements, but as the pressure for solutions increases, the industry is investigating how to improve the sustainability of its installations. DNV’s Abate notation is an initiative in this direction.

“The Abate notation aims to help offshore owners reduce greenhouse gas emissions from their facilities, creating engagement and commitment from both owners and their management systems, through setting clear goals, measuring progress, and of being able to adjust plans to incorporate future technologies,” said Geir Fuglerud, director of Offshore Classification for DNV’s Marine division. “We want to offer the industry practical solutions to reduce emissions, which is why it has been so helpful to work with an engaged and proactive owner like Altera on this pilot to identify areas for improvement.”

Abate notation provides a structured approach to identifying and evaluating the implementation of abatement measures, based on the design and operation of individual facilities, to enable measurable reductions in a facility’s emissions. Developed primarily to cover offshore oil and gas installations, the general principles can also be applied to other floating offshore installations.

Altera Infrastructure is a leading global energy infrastructure services group primarily focused on owning and operating offshore oil assets in the North Sea, Brazil and the East Coast of Canada. It has more than 2,000 employees and consolidated assets of approximately US$4.3 billion, comprised of more than 40 offshore assets, including FPSOs, tankers, tow ships and a maintenance and safety unit.
