Marine infrastructure plays a critical role in the functioning of ports, harbours, waterways, and waterfront industries. Whether it’s a commercial wharf, a public jetty, or a bulkhead wall, ongoing maintenance is essential to ensure structural integrity, safety, and uninterrupted operation.
At Polaris Marine Group, we provide comprehensive marine infrastructure maintenance services designed to protect your assets and extend their operational lifespan.
Why Marine Maintenance Matters
The marine environment is harsh and unforgiving. Constant exposure to saltwater, wave action, vessel movement, and tidal forces accelerates wear and tear. Left unchecked, corrosion, degradation, and structural fatigue can compromise safety, increase repair costs, and even lead to failure.
Proactive maintenance helps identify issues before they escalate. By carrying out routine inspections and timely remedial work, you reduce downtime, avoid costly emergency repairs, and ensure compliance with safety and operational regulations.
A Flexible Platform for Marine Logistics
Polaris Marine Group’s dumb barges are used in a wide range of marine and coastal operations. From transporting precast concrete segments and piling equipment, to acting as a working platform for cranes and excavators, these barges are built for stability and durability.
Their modular, open-deck design allows for quick and adaptable loading, making them ideal for projects that require shifting or oversize equipment. We also supply configurations suited to specific tasks, such as dredging, jetty construction, or waterfront demolition.
Scheduled & Reactive Maintenance Programs
Polaris Marine Group offers both scheduled maintenance programs and rapid-response services for urgent repairs. We tailor our maintenance approach to the asset type, location, and level of use. For high-traffic commercial berths or ferry terminals, regular inspections and servicing may be needed monthly or quarterly. For more isolated assets, a detailed annual inspection may be sufficient.
In the case of unexpected damage, such as from vessel strikes, storm events, or structural failure, our teams can be deployed quickly to carry out emergency repairs, restore service, and stabilise conditions to prevent further damage.
Full-Service Capabilities
We maintain a wide range of marine infrastructure including:
Jetties and pontoons
Wharves and piers
Seawalls and revetments
Piles and pile caps
Floating walkways and access platforms
Moorings and navigation aids
Our crews have the equipment and training to work safely and efficiently in marine environments. Whether repairs are needed above or below the waterline, we draw on our in-house capabilities, including commercial diving, crane barge operations, pile reinstatement, welding, and marine carpentry.
Condition Assessments & Reporting
Maintenance begins with knowing the current state of your infrastructure. Our team conducts detailed condition assessments, using visual inspections, structural testing, and underwater surveys where required.
We provide clear, practical reports that prioritise maintenance needs, outline repair recommendations, and support budgeting and compliance planning.
This documentation is essential for asset managers, councils, and operators needing to plan upgrades, manage risk, and meet regulatory obligations.
Minimising Disruption to Operations
Many marine assets serve public or commercial users, such as ferry commuters, freight vessels, or recreational boats. Polaris Marine Group plans maintenance works to minimise disruption.
This may include working at night, in stages, or during scheduled closures. Our crews are experienced in working in live operational environments, maintaining safety for both workers and the public.
Long-Term Asset Protection
Maintenance is not just about patching visible issues, it’s about protecting the long-term value of marine infrastructure. We advise clients on protective coatings, cathodic protection systems, structural reinforcements, and other methods to slow deterioration.
Where applicable, we also recommend design modifications that reduce exposure or improve resilience.
Our goal is to reduce lifecycle costs for asset owners by avoiding premature replacement and extending the usable life of marine structures.
Environmental Considerations
Marine maintenance work must be carried out with environmental sensitivity.
Polaris Marine Group complies with all regulatory requirements around sediment control, water quality, and habitat protection.
We use turbidity curtains, low-impact methods, and qualified personnel to ensure works are carried out responsibly.
