HARTLEPOOL, UKBeach Energy has contracted JDR to supply equipment for a subsea production system serving gas fields in the Otway basin offshore Victoria, Australia.

The scope covers four thermoplastic subsea umbilicals ranging in length from 400-4,360 m (1,312-14,304 ft), and termination hardware that includes hydraulic and electrical flying leads.

Beach produces gas from the Halladale, Speculant, Geographe and Thylacine fields, with production piped to the Otway Gas Plant near Port Campbell for processing. Late last year the Geographe 4 and 5 wells came onstream, and recently, Beach concluded successful drilling of Thylacine North 1.

JDR’s thermoplastic umbilical system should allow Beach to increase production at the Otway Gas Plant, delivering a new supply of gas to Australia’s East Coast.

The umbilical with a Subsea Distribution Unit (SDU) will be installed through an existing J-tube on the Thylacine wellhead platform, with a second umbilical connected to the SDU to tie in Thylacine North-1, 4 km (2.5 mi) northwest of the platform.

This cable’s integral SDU will allow two additional subsea umbilicals to connect the Thylacine North-2 and Thylacine West drill centers, with JDR’s electrical and hydraulic flying leads connecting the four subsea wellheads to terminations on each umbilical.

In addition, the company’s service technicians will perform installation and commissioning.

Equipment will be manufactured at JDR’s complex in Hartlepool, northeast England, with the umbilicals shipped by sea on 9.2-m (30.2-ft) cable installation reels for delivery this September.
