TGA Subsea Cable Construction Underway

Cable laying operations of the first section of the Tasman Global Access (TGA) undersea cable are set to begin this month in Raglan.

Telecommunications companies Spark, Vodafone and Telstra are investing approximately USD $70 million to build the TGA cable.

The consortium of Spark, Vodafone and Telstra have contracted Alcatel-Lucent Submarine Networks (ASN), now part of Nokia, to lay the first cable between Ngarunui Beach at Raglan and Narrabeen Beach in Australia.

Spark’s General Manager Wholesale and International, Lindsay Cowley, and Vodafone’s Wholesale Director, Steve Rieger, jointly commented on behalf of the consortium: “The work in Raglan marks an exciting and important milestone on the journey to having the TGA cable ready to start carrying data across the Tasman towards the end of 2016.

“The first stage will see the crew of the MV Tranquil Image – a specially fitted out New Zealand vessel – bury a three kilometre stretch of fibre optic cable from Ngarunui Beach, through the surf zone and into the ocean.

“Once the Raglan shore landing works are complete, a larger specialised ASN ship will arrive in New Zealand to connect the next section of cable, taking it across the Tasman and eventually connecting it to the Narrabeen Beach landing in Australia.”

The cable laying activities at Ngarunui Beach are scheduled to start on March 29, and this first stage will take approximately one week to complete.

“The goal is to complete this first stage as quickly and seamlessly as possible, however the health and safety of the crew, and the public, are our first priority.

“We are keeping the Raglan community informed of the key construction dates and activities and we are extremely grateful for their understanding and support of the project so far,” Lindsay Cowley and Steve Rieger added.

The TGA cable is currently on track to be completed, tested and ready for service by the end of 2016. The 2,300km length of cable is comprised of two fibre pairs, and will have a total capacity of 20 terabits per second.
