Perth, Australia, 2nd March 2021: Aquaterra Energy, a leader in global offshore engineering solutions, has secured a multi-million-dollar (USD) riser contract with a marine vessel owner and operator, for deeper water well intervention projects mainly in the Asia Pacific region.

Aquaterra Energy will deliver a large-bore (7 3/8”) AQC-CW completions and workover riser system with automated handling package that will operate in water depths of up to 1,500m. The system has been designed to withstand repeat make and breaks, whilst offering a gas tight metal-to-metal seal. The solution can be operated from a lightweight intervention vessel, semisubmersible or from a jack-up rig as a surface riser, open water subsea riser or as a landing string.

The NACE compliant technology and unique pipe to connector attachment eliminates welding – making the riser lighter offering enhanced water depth deployment capacity. In addition, the ability to pressure test each connection upon make up provides enhanced environmental reassurance against well bore fluid discharge.

James Larnder, Managing Director of Aquaterra Energy said: “This project marks a key milestone in our Asia Pacific success story, whilst also diversifying our AQC riser offering into deeper water operations. All our systems are intelligently engineered to be efficient with no wasted materials and a focus on quick connection to reduce operational time whilst assuring integrity. Importantly, these efficiencies also support our own and our customers’ decarbonisation efforts.”

Aquaterra Energy will manage the entire project scope via its in-house engineering and project management teams. Throughout the project, Aquaterra Energy will provide fatigue utilisation and management through riser monitoring hardware to extend asset life, as well as automated hands-off connector makeup and umbilical handling equipment to improve safety and enhance offshore efficiency.
