ABL chosen for installation of Australian interconnector

Energy and marine consultancy ABL has been appointed as marine warranty survey (MWS) to support the installation of Australia’s Marinus Link interconnector – a critical energy infrastructure project in facilitating Australia’s energy transition.

Under the contract, ABL’s operations in Australia will provide marine warranty survey services to support the marine transportation and installation (T&I) campaign for the submarine part of the interconnector.

The Marinus Link project will construct a 345-kilometre-long interconnector between Tasmania and Victoria, with 255 kilometres running undersea across Australia’s Bass Strait. The asset is recognised by the Australian Energy Market Operator as essential in supporting the transition of the country’s energy mix from coal-fired power, enhancing renewable energy integration and storage in the wider Australian grid network, and enabling the efficient flow of energy between Tasmania and Victoria.

“Marinus Link is a major development project in Australia’s energy strategy. It will facilitate the interconnection of enough power to support the equivalent of 1.5 million homes, including providing wider access to renewable energy as more of it comes online. We are pleased to bring ABL’s global track record in supporting the safe delivery of interconnection projects, combined with our local market knowledge, to support this vital initiative.”

Jason Hannath, ABL’s Country Manager in Australia

Under its scope of work, ABL will support Stage 1 of the Marinus Link development, including transportation operations, trenching, cable lay and cable burial operations, landfall and pull-in operations. Services will include the technical review of project documentation, drawings and calculations, vessel suitability surveys and assurance for the proposed specialised fleet, DP assurance where relevant, and on-site attendance to witness and approve warranted operations.

ABL – part of Oslo-listed global consultancy ABL Group – has been operational in Australia since 1988. With ABL’s local headquarters in Perth, the group also has offices in Brisbane, Sydney and Melbourne via its sister company, renewable energy consultancy OWC.

Globally, ABL has supported as MWS on transportation and installation of more than 45 interconnectors.
