Innovative Marine Construction Techniques for Waterfront Infrastructure Projects

Built For Challenge
Learn how Tas Marine uses proven Marine Construction Techniques to deliver high-quality marine and waterfront infrastructure solutions in Australia.

Australia’s extensive coastline and reliance on maritime infrastructure make marine construction a critical sector for economic growth, transport, tourism, and community development. From ports and marinas to jetties, pontoons, and ferry terminals, waterfront infrastructure must perform reliably in some of the world’s most demanding marine environments. As coastal conditions evolve and sustainability expectations rise, innovative marine construction techniques are playing a vital role in delivering resilient, long-lasting solutions.

Australia’s Unique Marine Construction Environment

Marine construction in Australia presents a unique set of challenges. Projects must contend with tidal variations, wave action, corrosive saltwater exposure, and diverse seabed conditions ranging from soft sediments to hard rock.

In addition, strict environmental regulations and coastal engineering guidelines require construction methods that minimise ecological disturbance while maintaining structural integrity. These factors are driving innovation across the industry, encouraging smarter design, advanced equipment, and efficient construction methodologies.

Modern Marine Construction Techniques Transforming Waterfront Projects

Today’s marine construction techniques focus on delivering greater efficiency, improved safety, and long-term structural performance across waterfront projects. Modern approaches allow marine infrastructure to be built faster and with reduced environmental impact.

Key techniques include:

  Modular and prefabricated systems for jetties, pontoons, and marina structures, with components manufactured off-site and rapidly installed on location

  Reduced construction time over water, improving safety and minimising disruption to surrounding marine environments

  Driven piling and sheet piling systems to create stable foundations in challenging seabed conditions

  Advanced piling methods are designed to withstand heavy structural loads while incorporating corrosion protection for long-term durability

  Specialised marine plant and equipment, including floating cranes and barges, enabling precise installation in restricted access or deep-water environments

Prefabrication and Modular Systems for Faster, Smarter Builds

Prefabrication is a major innovation in marine construction, allowing key structural elements to be built off-site with greater quality control and fewer weather-related delays. Modular pontoons, precast deck sections, and floating structures can then be installed efficiently once site preparation is complete, reducing time spent working over water. This approach improves safety, delivers more predictable project costs, and minimises disruption to existing waterfront operations.

Sustainable and Climate-Resilient Marine Infrastructure

Sustainability and resilience are now critical considerations in waterfront infrastructure, with marine structures designed to adapt to rising sea levels, stronger storms, and coastal erosion. Innovative construction techniques incorporate elevated platforms, flexible connections, and durable materials suited to harsh marine environments. Detailed coastal modelling allows Australian projects to work with natural wave, tidal, and sediment processes, improving long-term performance while reducing environmental impact.

Innovative Equipment and Technology in Marine Construction

Advancements in marine construction equipment have expanded what is possible in complex waterfront projects. Specialised vessels, jack-up barges, and floating work platforms provide safe, stable access, while precision lifting technologies enable accurate installation of piles and heavy components. Tas Marine brings proven innovation to piling works, with pioneering hydraulic hammers and crane-based pile spinning techniques that enhance control during installation and improve efficiency in demanding marine environments. Together, these capabilities reduce risk, strengthen safety outcomes, and support the delivery of marine projects across complex coastal conditions.

Bellerive Stormwater Upgrade

Client: City of Clarence

Date Completed: May 2025

Total Contract Sum: $1.2M

Description of works:

Tas Marine delivered Clarence City Council’s largest infrastructure project to date, including constructing a temporary sheet pile cofferdam across Bellerive Beach to enable excavation for a new stormwater outfall. Over 200 tonnes of steel were installed using specialised equipment. The new upgrade reduces flood risk to surrounding residential areas and supports long-term coastal resilience.

New Boat Stack Seawall

Client: Williamstown

Date Completed: Current

Total Contract Sum:

Description of works

Tas Marine Construction has been contracted to deliver a 200-metre long break wall at Williamstown.

The combination wall design consists of 16mm sheet piles with rock-socketed piles installed at every second sheet. With challenging hard basalt ground conditions, Tas Marine is applying its specialist hard rock drilling expertise to drill and concrete the piles into position. Completion is scheduled for late 2025.

Travel Lift Jetties

Client: Royal Yacht Club of Victoria

Date Completed: Current

Total Contract Sum: 

Description of works

Tas Marine Construction was awarded the competitive tender to replace the Royal Yacht Club of Victoria’s aging travel lift jetties. 

Works include demolition of the existing jetties, installation of new piles, and the supply and fit of steel superstructure and precast deck units. The project is progressing on schedule and will be completed ahead of the arrival of the new travel lift in mid-October.

Waikawa Breakwall (NZ)

Client: Port Marlborough

Date Completed: Current

Total Contract Sum: $12.2M

Description of works

Construction of 500m long piled break-wall in up to 18m water depth. Precast wave panels are 8m deep weighing 25t. Total weight of structure 6000t.

Details of any Variations

Variations for additional PDA testing, pile lengths, pull out tests, acceleration and pile fins were approved and paid. Some painting was deleted and client was given a discount.

Bellerive Yacht Club new Marina arm

Client: Bellingham marine Australia
Date completed: Feb 2025
Total contract sum: $380,000
Description of works:
Supply and install steel piles with poly sleeves into rock. Take delivery of pontoons and assemble on water. Fit abutment and gangway. Install coverboard and buffer.

TMC was able to use our new 40t crane for the duration to save hiring a crane. The trucks were often delayed so would have meant lots of variation charges if we had to hire a crane extra times
