A composite jumper designed and manufactured by Strohm is to feature in deepsea mining technology being developed by offshore contractor Allseas.
Allseas’ deep-sea collection system technology has been designed to responsibly recover polymetallic nodules from the seabed at depths of 4,000-6,500 m.
This is the first time Strohm’s Thermoplastic Composite Pipe (TCP) solution will be used in a deep-sea mining application.
Under the agreement, Strohm will provide Allseas with a spoolable TCP Jumper to connect the seabed vehicle to the vertical transport system.
Manufactured at Strohm’s facility in the Netherlands and delivered in long spoolable lengths, TCP is fitted with an abrasion-resistant liner which provides a distinct advantage over short, flanged rubber-based pipes typically deployed for slurry transport operations, the company says. The jumper’s inner bore is also extremely smooth, and its strong composite wall provides good collapse resistance while maintaining sufficient flexibility.
