Floating production systems versus subsea tiebacks: the costs?

This model estimates the line-by-line costs of an FPSO project, across c45 distinct cost lines, in order to quantify the potential savings of a tieback or a ‘fully subsea’ development.

Our estimates drawing on four technical papers, as illustrated in the backup tabs of the model. For a full discussion, see our recent note ‘The future of offshore: fully subsea‘.

We estimate c$750M of cost savings for a tieback, and c$500M of cost savings for a fully subsea development, as compared against a traditional project with a traditional production facility.  Please download the model to see the different cost drivers, line-by-line.

Development Concepts: how much CO2?

This data-file quantifies the costs and CO2 emissions associated with different oilfield development concepts’ construction materials.

We have tabulated c25 projects, breaking down the total tonnage of steel and concrete used in their topsides, jackets, hulls, wells, SURF and pipelines.  Included are the world’s largest FPSOs, platforms and floating structures; as well as new resources in shale, deepwater-GoM, Guyana, pre-salt Brazil and offshore Norway.

Infill wells, tiebacks and FPSOs make the most efficient use of construction materials per barrel of production. Fixed leg platforms are higher, then gravity based structures, then FLNG, and finally offshore wind (by a factor of 30x).
