The McConnell Dowell name is synonymous with marine design and construction, with over 50 years of award-winning solutions for wharves, jetties, ocean outfalls, breakwaters, causeways and submarine pipelines. 

Innovation is our hallmark. It was our purpose-built barge that laid twin 1200 mm diameter pipelines across Botany Bay in Sydney. Our modular approach to wharf construction made us industry leaders and the partner of choice for resources clients like Rio Tinto and BHP Billion. 

Our fleet of marine equipment is ahead of the world, while our systems and procedures for marine project delivery are proven in the protection of our people, plant and the environment.
