Lockton advises Marinus Link on landmark financial close for subsea interconnector project

As insurance adviser and broker for the wider Marinus Link project, Lockton provided guidance on insurable and non-insurable risks, identifying the parties best placed to assume and/or insure these risks while meeting project finance requirements.

Stage 1 of Marinus Link project will deliver a 750 MW high-voltage direct current (HVDC) cable system, comprising 255 kilometres undersea and 90 kilometres underground. Once completed, the project will more than double the electrical transfer capacity between Tasmania and Victoria, unlocking Tasmania’s “Battery of the Nation” potential, supporting new renewable generation, and strengthening energy security across states.

Lockton worked closely with the Marinus Link team throughout the development phase. Drawing on the expertise of its global energy practice, the firm provided specialist risk and insurance advice from the earliest planning stages through to Financial Close.

Alistair Williams, National Manager – Energy Construction at Lockton, said: “Reaching Financial Close on a project of this scale is a landmark moment for Australia’s energy transition. We are proud to have supported Marinus Link with specialist risk and insurance expertise, helping deliver a bankable insurance program that underpinned the project’s success. We look forward to continuing this partnership through the delivery phase.”

Insurance plays a critical role in underpinning major energy and infrastructure projects, particularly those subject to project finance.

Construction of Marinus Link is scheduled to commence in 2026, with Lockton continuing to support the project through delivery – reinforcing its commitment to transformative infrastructure that drives clean growth and energy resilience.
