The Otway Basin covers an area of 150 000 km2 and spans from southeastern South Australia to southwestern Victoria, with 80% lying offshore in water depths ranging from 50 to 3000 m. In Victoria, Beach’s operations in the Otway Basin involve natural gas production from the Halladale and Speculant natural gas fields, as well as the Geographe and Thylacine gas fields, with natural gas being piped and processed at the Otway Gas Plant near Port Campbell.
JDR’s thermoplastic umbilical system will allow BEL to increase production from its Otway Gas Plant and deliver a new supply of gas to Australia’s East Coast.
JDR’s umbilical with a Subsea Distribution Unit (SDU) will be installed through an existing J-tube on the Thylacine well head platform. A second umbilical will be connected to the SDU to tie in the Thylacine North-1 well which is 4 km northwest of the platform. This cable will also have an integral SDU which will allow two additional subsea umbilicals to connect the Thylacine North-2 and Thylacine West drill centers. JDR will provide electrical and hydraulic flying leads to connect the four subsea wellheads to terminations on each umbilical. The company will also supply service technicians for installation and commissioning.
JK Lim, Region Manager for Singapore at JDR, commented: “This award marks a key milestone in our Asia Pacific success story, as we continue to prove our subsea capabilities in this competitive market. The Otway project is one of our largest umbilical contracts to date, so it’s an extremely proud moment for the team. But we won’t stop there, Australasia is an important location for us, and we see an abundance of opportunity here.”
The umbilicals and accessories will be manufactured at JDR’s state-of-the-art facility in Hartlepool, the UK, from which JDR will package and ship the umbilicals by sea using 9.2 m cable installation reels. Delivery is currently scheduled for September 2022.
