GLTE project maps carbon emissions

Statoil, Subsea 7, FMC Technologies and Nexans partnered with Xyntéo to form this unique Global Leadership & Technology Exchange (GLTE) project, which mapped the full life-cycle carbon emissions of the Tyrihans oil and gas field offshore Norway.

Using Xyntéo’s Carbon, Decision and Scenario Mapping methodology (CDS), we mapped the carbon footprint of Tyrihans over its entire life cycle and its supply chain; linked emissions to the decisions that led to them and explored less carbon intensive alternatives for future developments.

This Tyrihans CDS study found that to reduce the carbon emissions from a new field, it is crucial to take them into account early in the planning process before a concept is selected.

This works -- Tyrihans scores about 67 per cent below the global average in terms of the carbon intensity of its direct emissions. A hypothetical switch to complete subsea processing at Tyrihans indicates further emissions cuts could be realised: a reduction of up to 40 per cent using a turbine-driven subsea processing station and a decrease of up to 80 per cent if it is powered by electricity from shore.

This underlines the importance of seeking smarter solutions and challenging existing, more conventional concepts to be better equipped for a lower-carbon future.
