What this SWMS covers
Boats and barges serve as essential infrastructure for construction projects located in or adjacent to waterways where conventional land-based access is impractical or impossible. These marine vessels function as floating work platforms supporting construction equipment and personnel, transport vehicles for moving materials and plant between shore bases and work sites, personnel transport providing worker access to islands and offshore structures, accommodation and welfare facilities for remote marine construction projects, and storage platforms for fuel, materials, and equipment. The diversity of construction marine operations spans small aluminium dinghies for bridge inspection work through to 50-metre self-propelled barges carrying 200-tonne excavators for major dredging projects, with operational complexity scaling accordingly. Marine construction activities using boats and barges include bridge construction and maintenance where barges support piling rigs, concrete pumps, and construction cranes beneath bridge structures, wharf and jetty construction utilising barges as work platforms for marine piling, formwork installation, and concrete placement, underwater pipeline installation where barges support excavation equipment and pipe-laying operations, environmental works including riverbank stabilisation and wetland construction, services installation beneath waterways using directional boring or trenching equipment mounted on barges, marine salvage and demolition work requiring floating platforms for cutting and lifting operations, and emergency response work accessing flooded areas or supporting marine infrastructure repairs. Each application creates specific hazard profiles requiring tailored risk assessments and control measure implementation. Construction barges vary enormously in size, configuration, and capability. Simple flat-deck barges or pontoons provide stable floating platforms for equipment and personnel but require separate tug or workboat propulsion for movement. Self-propelled barges include integrated propulsion systems allowing independent navigation, typically featuring bow thrusters for precise positioning in confined waterways. Spud barges incorporate retractable steel spuds or legs that lower to riverbed or seabed providing extremely stable platforms for piling work or heavy lifting operations. Jack-up barges extend this capability with hydraulic legs capable of lifting entire barge clear of water surface, creating stable platform immune to tidal or wave movement. Specialist barges include crane barges equipped with heavy-lift cranes up to 300-tonne capacity, dredging barges with excavation equipment and material handling systems, and accommodation barges providing living quarters for construction crews on multi-week marine projects. Workboats supporting construction operations range from small aluminium utility boats for personnel transport and light cargo through to powerful multi-engine vessels capable of towing loaded barges. These support vessels typically include safety equipment exceeding minimum commercial vessel requirements given the elevated hazards of construction operations, comprehensive communication systems allowing coordination with shore bases and other vessels, adequate deck space and loading capacity for equipment and materials, and environmental protection systems preventing fuel or chemical spills. Modern construction workboats increasingly incorporate GPS positioning systems, depth sounders, and marine radar supporting safe navigation in congested waterways and during reduced visibility conditions. Regulatory requirements governing construction marine operations combine maritime safety legislation administered by Australian Maritime Safety Authority and state maritime authorities with workplace health and safety legislation administered by state work health and safety regulators. This creates complex compliance environment where vessel operations must satisfy National Standard for Commercial Vessels while simultaneously meeting Work Health and Safety requirements for construction work. Operators must hold appropriate marine qualifications including Coxswain certificates for smaller vessels and Master certificates for larger vessels depending on vessel size and operational area. Construction workers operating plant and equipment on barges require standard construction qualifications including high-risk work licences for crane or excavator operation regardless of marine location. Companies operating construction marine vessels must hold commercial vessel certificates of survey, commercial vessel registration, appropriate marine insurance, and documented safety management systems meeting both maritime and workplace safety requirements.
