Whether you're looking for the latest project information or a quick snapshot of activity, the map is a valuable new tool to help keep communities informed and connected as construction progresses.

Project Marinus event marks next phase of delivery for Marinus Link and NWTD

In early October, TasNetworks and Marinus Link joined government, industry and community leaders at the Heybridge converter station and switching station site near Burnie to mark the start of construction on the North West Transmission Developments (NWTD) and Marinus Link - collectively known as Project Marinus - as works ramp up across Tasmania and Victoria.

Heavy lifting keeps NWTD works on track

Moving a 110-tonne transformer from Burnie to Sheffield was no small feat, requiring months of planning and specialist equipment.

Before the journey could begin, the 220/110 kV 200 MVA transformer underwent extensive testing, draining, disassembly and refurbishment. It was then carefully lifted onto a specialised trailer using a 300-tonne crane, ready for transport to its new home at the Sheffield substation.

The move started at 2am, supported by transport escorts and a TasNetworks line crew. After travelling along a carefully planned route, which had required temporary road widening works at two intersections near Sheffield, the transformer arrived safely on site and was lowered into position later that morning.

Once installed and commissioned, the refurbished transformer will play an important role in maintaining network security during planned outages on the Sheffield-Burnie transmission line, helping support the delivery of NWTD.

The successful move brought together teams from across TasNetworks, delivery partner Zinfra and a range of specialist contractors, all working to a tightly coordinated schedule alongside other construction activities at Sheffield substation.
