Subsea sand detection and erosion monitoring to Equinor
Tuesday 14 September 2021
ClampOn has received a contract to supply Subsea Erosion Monitors and Particle Monitors for the Kristin Sør development operated by Equinor.
The non-intrusive subsea erosion monitors will be installed in bends and will be an effective tool in helping monitor for any wall thickness loss.
Included in the scope of supply from ClampOn are non-intrusive subsea particle monitors. These will be installed in funnels and clamped to the outside of the pipe about two pipe diameters after the bend. Any particles in the flow hit the inside wall of the pipe and generate a noise. This noise is picked up by the sensor which, based on the noise signal, also quantifies the amount of sand produced. This gives the operator early warning of any sand production, so is an important measure in monitoring pipe condition and maintaining optimal safe production.
Contract Value
The contract is worth close to NOK 10 million.
The Kristin Sør development consists of Lavrans and Kristin Q, with satellites to the existing Kristin platform. It is a high-pressure, high-temperature gas-condensate field, located off the coast of mid-Norway.
Aker Solutions has the contract for the subsea templates, subsea trees and manifolds.
ClampOn has previously supplied topside and subsea instrumentation to Kristin for both sand monitoring and pig detection.
