IJMUIDEN, the Netherlands — Strohm will manufacture two Thermoplastic Composite Pipe (TCP) flowlines to Woodside Energy for the relief well emergency response system for the $12-billion Scarborough gas-condensate development offshore Western Australia.
This is for the project’s well construction phase.
Scarborough, located in the Exmouth sub-basin, will feature up to 13 subsea production wells which will be tied-back to a floating production platform moored in 900 m water depth.
Its gas will be piped to the Pluto LNG export facility near Karratha.
The emergency response system, with two 600-m long TCP flowlines, will be stored on land for delivery to the field in the event of a drilling-related source control incident.
In such a scenario, two floating drill rigs would pump high-density kill fluid, using well kill manifolds on the seabed. The TCP flowlines would be laid on the seabed to connect the manifolds, allowing commingling of kill fluid to a relief well.
It is the first time TCP has been chosen for such an application. Strohm will deliver the flowlines spooled onto storage and installation baskets which can be lowered to the seafloor from a local IMR vessel.
Strohm Representative, Australia, Robby O’Sullivan, said: “The Scarborough reservoir…is estimated to contain 11.1 tcf of dry gas. TCP was chosen because it is a smoothbore, lightweight pipe and is easy to transport and deploy offshore making it ideal in the event of an emergency response situation.
“It is also very compact and can be safely stored on spools or pallets.”
