Vocus has signed a deal with the Barossa Joint Venture to build, operate and own a 500-kilometre, high-capacity submarine fibre optic network in the Northern Territory.

The Bonaparte Basin Cable Loop (BBCL) will be integrated into the 2100km Vocus North West Cable System (NWCS), which the telco picked through its acquisition of Nextgen Networks in 2016.

The Barossa Joint Venture comprises ConocoPhillips Australia Barossa, Santos Offshore and SK E&S Australia. The Barossa Offshore project will provide a new source of gas to the existing Darwin LNG facility to backfill the facility from 2023 when the existing offshore gas supply from the Bayu-Undan offshore field is expected to be exhausted.

The NWCS links Darwin and Port Hedland and already provides services to a number of offshore LNG operations in the Browse Basin.

Vocus said a three-year design and construction phase is expected to be followed by a 15-year minimum service term for the operation and maintenance of the network.

“We have developed a highly robust and resilient architecture that will support Barossa and connect to our existing submarine cable assets off the North-West coast of Australia,” Vocus Group managing director Kevin Russell said.

The Barossa development concept includes a floating production storage and offloading (FPSO) facility, subsea production system and gas export pipeline.

The project will be located in the Bonaparte Basin approximately 300 kilometres north of Darwin.

Vocus has partnered with Alcatel Submarine Networks for the cable manufacture and submarine works.

This marks the fourth submarine project Vocus has embarked in partnership with Alcatel which includes the NWCS, the 4600km Australia Singapore Cable in 2018 and the 4800km Coral Sea Cable System (CS2) for the Department of Foreign Affairs and Trade (DFAT) in 2019.
