NBN Submarine Cable Network

Client: Visionstream
Location: Port Hacking, Sydney Harbour, Lake Macquarie. SW
Date: 2017-19

As part of the NBN roll out across Australia The Diving Co. has partnered with Visionstream to provide an integrated end to end submarine cable laying service. Providing feasibility studies, environmental surveys and subsequent authority approvals the company has on all these projects provided rodding and roping of ducts, dive support for new directional bores, road transport, crainage, logistics, cable lay barges, tugs, floating plant as well as post lay burial and cable protection. Many of these cable routes cover areas of environmental significance such as seagrass protection areas and thus cable protection methods such as installation of Protectorshells provides both cable security but compliance with EPA and Dept. Of Fisheries requirements. The lake Macquarie project involved the lay and burial of in excess of 9km of cable at 4 separate crossings and the utilisation of a number of different post lay burial tools.
