Operators Technology plans are showing increased experience by operators in technology deployments to support subsea developments. In addition remote and automated subsea inspection technologies are reducing the number of offshore visits and manned interventions.
Insights from Operators’ experience reported in their Technology Plans (2018-22)
Summary Findings (Click on Sub-Categories for detail)
- Pipelines, Risers & Jumpers
Subsea Technologies in Pipelines, Risers & Jumpers are focussed on cost efficient pipeline manufacturing processes, adding corrosion resistance linings to carbon steel pipe, use of Composite materials and Jumper Heating for heavy oil. - Manifolds, Umbilical’s & Control Systems
Manifolds, Umbilical’s and Control systems have seen an increase in numbers of technologies, doubling in numbers since the 2020 survey data, updated new generation control systems, non-metallic protection structures for manifolds, wellheads and Pipelines/umbilical’s, new methods of umbilical fault finding becoming adopted by operators this year. - Inspection & Intervention Systems
Advances in Autonomous Vessel design, both subsea and surface modes of deployment enable unmanned survey and subsea inspections remotely from the host vessel, Diverless methods of scanning pipelines & Risers, Retrofittable sand detectors - Processing, Boosting & Storage
Subsea Technologies in Processing Boosting & Storage – Operators are focussed on expanding subsea facilities while maximising available deck space with subsea processing facilities including Subsea Gas Compression and Subsea Water Treatment, multiphase pumping to enhance tieback distance and wellhead seawater injection with seawater pump on the Wellhead.
