MOORING & AtoN SERVICING

Polaris Marine Group provides expert mooring and AtoN servicing across Australia, including inspections, repairs, and installations.
Polaris Marine Group delivers high-quality mooring and AtoN (Aids to Navigation) servicing for government, commercial, and private marine clients across Australia. With decades of experience in coastal operations, our team ensures moorings and navigational aids are installed, inspected, and maintained to the highest standards of safety, compliance, and performance. Moorings and navigation aids form the invisible infrastructure that keeps vessels safe and operations running smoothly. Whether it’s a swing mooring for a commercial barge, a pile mooring for a fuel terminal, or a cardinal mark helping guide marine traffic through a busy channel, each asset must perform without fail. Our job is to ensure it does. We provide complete servicing programs, from routine inspections to full-system replacements. With dedicated marine plant, divers, technicians, and engineers, we manage all aspects of mooring and AtoN upkeep. We’re on call for urgent repairs, and available for long-term maintenance contracts across harbours, inland waterways, and offshore zones.

Project Summary

Key Achievements

Mooring Inspections, Installation and Maintenance

Polaris Marine Group services a wide variety of mooring systems used in commercial and industrial marine operations. These include swing moorings, pile moorings, fore-and-aft systems, dolphin berths, and mooring buoys. We also provide mooring solutions for temporary works, barge positioning, vessel lay-up, and marine construction support. Each mooring is unique in its design and site conditions, so we begin by assessing the specific load requirements, seabed profile, tidal patterns, and vessel dimensions. We then inspect or install appropriate components, which may include anchors, ground chains, risers, buoys, swivels, and shackles. All gear used meets relevant Australian standards, and we document every component’s location and condition. Our diving teams carry out in-water inspections, replacing worn parts or retrieving failed systems as needed. Our surface crews and marine plant provide the lift capacity and access to perform maintenance above and below the waterline. For moorings in environmentally sensitive areas, our team works under strict controls to minimise seabed impact and protect marine habitats. Polaris Marine Group maintains a comprehensive inventory of mooring hardware, which means fast mobilisation for emergency jobs and efficient turnaround for scheduled works.

Aids to Navigation—such as lateral markers, channel beacons, leads, cardinal marks, and mooring buoys—are essential for safe vessel movement. Polaris Marine Group services both physical and electronic AtoNs on behalf of port authorities, maritime agencies, and asset owners. Our AtoN servicing capability covers installation, repair, cleaning, light replacement, battery checks, and telemetry inspections. We work on floating and fixed aids, including pile-mounted lights, isolated danger markers, and buoys with integrated GPS or AIS transmitters. We regularly undertake cyclical servicing of AtoNs across channels, fairways, dredged areas, and port approaches. These services involve inspecting structural integrity, confirming positional accuracy, checking lighting performance, and cleaning lenses and reflective panels. All work is recorded in accordance with AMSA and IALA guidelines, and we provide detailed condition reports, photos, and location verification as part of every job. If an aid is damaged or out of station—whether by storm, vessel collision, or mechanical failure—we deploy crews to retrieve, repair, or replace the unit. We understand that downtime increases risk and cost, and we prioritise rapid, compliant reinstatement.

Expert Teams and Specialised Equipment

What sets Polaris Marine Group apart in mooring and AtoN servicing is our combination of skilled personnel and purpose-built marine assets. Our crews include experienced mooring technicians, commercial divers, marine engineers, and qualified operators, all trained in safe marine servicing practices. Our vessels are equipped for heavy lifting, shallow water access, and precision handling of navigation buoys and mooring gear. We use onboard cranes, davits, hydraulic tools, and real-time navigation to locate and service submerged and surface equipment with accuracy. Many of our vessels are designed for multi-day deployment, giving us the range and endurance needed for extended maintenance programs. We also maintain detailed digital records of all serviced moorings and AtoNs, supporting asset management, regulatory compliance, and client reporting. This means every service history, component detail, and inspection note is accessible for future planning.

Servicing in Remote and High-Impact Areas

Our work isn’t limited to city ports or calm waterways. Polaris Marine Group provides servicing in challenging environments, including offshore sites, exposed coastlines, and industrial zones with limited access. Whether we’re servicing a marker buoy off a breakwater, maintaining a mooring in a tidal estuary, or accessing a navigation light by barge and climber, we approach each job with risk-managed planning and field-tested methodology. We often partner with government authorities, defence clients, and major infrastructure contractors to manage asset condition across extended networks. Our logistical planning and fleet support allow us to reach remote zones efficiently, and we coordinate with local authorities to ensure each operation is undertaken safely and in accordance with local environmental regulations.

Long-Term Programs and Custom Solutions

Polaris Marine Group offers long-term contracts for mooring and AtoN servicing. These programs are tailored to the needs of each client, whether that means annual inspections, quarterly reporting, or integrated asset management with marine works and dredging programs. We work closely with asset owners to structure service schedules, monitor asset lifecycles, and forecast replacement needs. Our team also helps advise on mooring or marker upgrades—recommending more durable components, improved materials, or redesigned layouts to improve performance and reduce maintenance frequency. For clients in the early stages of planning new installations, we offer design and consultancy services for mooring layouts and AtoN positioning. From feasibility and charting to gear supply and installation, we deliver a complete end-to-end solution.

Protecting People, Assets, and the Environment

At Polaris Marine Group, we understand the role moorings and AtoNs play in ensuring maritime safety. We treat each asset with the seriousness it deserves—whether it’s a private mooring in a marina or a major lateral marker on a busy trade route. Our servicing practices are designed to prolong the life of the asset, enhance its performance, and reduce the risk of failure. We operate under strict safety protocols, with full job safety analyses, environmental controls, and incident management systems in place. Our teams are inducted and certified to meet the standards of each client, port, or regulatory agency.
