Offshore power interconnection is not new, there have been projects around, and some still operational, for over 50 years. Over the past 15 years however the interconnector market has accelerated and continues to do so. Subsea cable lengths are getting significantly longer, for example the 720 km North Sea Link ( that went operational in 2021. But there are plans for longer projects where the challenges of a tightening supply chain, deep water installation and system reliability will need to be addressed.

This presentation is focused at the subsea cable. We will briefly review the market status, and provide an overview of the key considerations for project development, installation and operation; thereafter the focus will be on the Australia-Asia PowerLink (AAPowerLink), in particular the Transport & Installation and Operations & Maintenance challenges.
