The Territory Government is delivering a significant upgrade of the Frances Bay Mooring Basin lock.

The upgrade will deliver new lock doors, modernise the mechanical and electrical systems and provide increased protection to help ensure the longer term sustainability, efficiency and safety of the facility.

This will provide an improved facility for the commercial fishing, seafood, marine maintenance and supplies and other maritime industries.

A design and construct tender was released in late 2021. Design work will take place in the second quarter of 2022, and work is likely to start on site before the end of 2022.

Work on site will be staged to manage impacts on basin and lock users, particularly at the start and ends of the various fishing seasons.

To ensure on site safety for workers and lock users, there will be intermittent periods of between 3-4 weeks in 2023 where it will not be possible for vessels to enter or exit the lock.

DIPL will work with the successful contractor and industry to avoid lock closures during the cyclone season and to provide access to the facility in the event of a cyclone watch being declared.

DIPL will continue to work with industry groups and basin users to develop business continuity plans and identify alternative facilities around Darwin Harbour to enable basin users to continue operations, maintenance and to moor vessels during basin closure periods.
