ACTOM: Act on Offshore Monitoring

What we do

The research proposed in ACTOM will work for the advancement of offshore monitoring to ensure alignment of CO2 storage projects with national and international regulations and societal concerns. An interdisciplinary consortium will apply methods to critically assess secure storage as this technology becomes implemented internationally as a key greenhouse gas emissions reductions strategy. The project team will build a web-based toolkit that will, for the first time, collect algorithms for designing optimal monitoring programs for offshore geological storage sites. Routines related to detecting subtle signals of a leak in a highly varying environment will be implemented in the toolkit.

Why is it important

Through the interdisciplinary approach, the tool will assist operators in their pre-operational phase in defining assurance monitoring programs that are aligned with regulations. The inevitable uncertainties in all measurements will be assessed, and methods on how to quantify and represent them will be recommended.

Potential legal conflicts between storage projects, and between storage projects and other uses of the seas, will be addressed in view of Marine Spatial Planning. We will explore the utility of the web-based toolkit to provide evaluated assessments of assurance monitoring as an aid to demonstrate Responsible Research and Innovation (RRI).


WP1 BASELINE: Will survey the regulatory requirements and opportunities and technical limitations laying the foundation for the marine monitoring program. This activity will underpin the other WPs, providing the necessary information on what level of assurance is expected from a monitoring program, alongside the present capabilities of marine measurements and monitoring.

:Will be responsible for building the toolkit based on verified algorithms for detecting weak signals in a highly variable environment and designing monitoring programs.

: Will study how the monitoring program can be used to communicate risks and benefits of subsea storage, and as a tool for public engagement through the Responsible Research and Innovation (RRI) framework.

: Will utilize the web toolkit built in WP2 and the knowledge learned in WP3 to study policy scenarios and demonstrate the toolkit on the P18 and Smeaheia storage sites as well as study sites in the Gulf of Mexico.
