A global subsea equipment solutions specialist has completed subsea installation monitoring work to support the Northern Lights Carbon Capture Storage project (CCS) in the North Sea.
This project marks the first occasion Ashtead Technology has been involved in a CCS programme, providing its integrated Deflection Monitoring System (DMS) and associated equipment. The DMS is a suite of structural monitoring systems to assist offshore construction operations, combining powerful software with modular technology.
Using the DMS, Ashtead Technology personnel and equipment successfully monitored the installation of an Integrated Satellite Structure (ISS).
Allan Pirie, chief executive of Ashtead Technology, said: “Our DMS has a strong track record in greenfield projects for oil and gas operators. It reliably and accurately provides real-time guidance during subsea structure placement work, anticipating any issues as the installation work progresses.”
Ashtead Technology’s dual independent DMS systems monitored and analysed parameters such as structure deflection, heading, pitch, roll and suction can differential pressures in real-time. This method of real-time monitoring is vital during the placement of suction can-based subsea structures as it ensures any potential issues can be acted upon immediately, reducing the risk of structural damage.
Developed by Equinor in partnership with Shell and Total, the Northern Lights project is the first of its kind in the region. The project aims to securely collect and transmit CO2 from onshore sources and store this under the seabed, to help reduce emissions and limit global warming.
