Ashtead’s DMS Assists Installation of Quad 204 Subsea Manifolds
Ashtead Technology said it has completed a subsea integrity management project to support BP’s Quad 204 redevelopment of the Schiehallion and Loyal fields, West of Shetland.
Namely, Ashtead deployed its new Deflection Monitoring System (DMS), to capture data required to safely deploy and install two subsea manifolds at water depths of 400 meters.
According to the company, the project was completed on time and allowed the subsea manifolds to be installed within 24 hours of the DMS being deployed. The entire project was controlled remotely via radio frequency and acoustic data links, removing the need for direct ROV or diver support intervention in order to gather attitude measurements.
Allan Pirie, chief executive of Ashtead Technology, said: “Whilst subsea structures look robust and are designed to last decades, they can be easily damaged during installation and incorrect orientation can lead to stress on flowlines and jumpers.
“In today’s increasingly harsh exploratory environments, data is key – it allows us to ensure subsea structures are installed to meet the differing complexities of developments around the world, offering long-term reliability and safety.
“Our Deflection Monitoring System was designed to provide a versatile platform for improved cost and safety performance, whilst reducing technological and operational risk and capturing key information that can extend the life of subsea assets.
“Quad 204 represents one of the most significant projects ongoing in the region and we are honoured to have been able to support BP with an integrity management solution for such an important field development.”
