At International Cargo Express (ICE), in our 35+ years of freight and shipping operations we’ve seen it all: enormous mining equipment, industrial machines, and multi-million dollar yachts. Moving oversized or project cargo across oceans requires far more than simply loading goods onto a vessel. Behind every successful shipment is careful planning, extensive coordination, and meticulous attention to regulations, safety standards, and risk management.

Below we cover the main things Australian importers and exporters need to know when moving heavy and oversized cargo globally.

RORO vs Flat Rack vs Breakbulk: Choosing the Right Path for Your Cargo

The first major decision we face in project cargo is choosing the right shipping method. For oversized freight that doesn’t fit inside standard containers, three primary options emerge: RoRo, Breakbulk or Flat Rack container shipping.

Flat Rack Containers – These are loaded onto standard container vessels and are ideal for oversized or heavy cargo that doesn’t fit inside a regular container. The cargo is secured onto a flat platform with no sides or roof.

RORO (Roll-On/Roll-Off) Vessels – These vessels are designed with built-in ramps, allowing cargo to be driven or towed directly onto the ship. This includes rolling cargo (like trucks and machinery) as well as static cargo, which can be loaded using MAFI trailers (large wheeled platforms) or secured directly to the deck.

Breakbulk Vessels – Used for large, heavy, or non-containerised items, breakbulk vessels rely on cranes to lift and place cargo individually onto the vessel, either with the ship’s own cranes or with breakbulk port equipment.

Costing models also differ. RO/RO pricing is often calculated on a “revenue tonne” basis—essentially, the volume or weight of the cargo. Flat Racks typically have fixed rates based on the space the container occupies on the vessel.

As freight forwarders, we carefully analyse both options with our clients, balancing not only costs but also schedules, port availability, and operational complexity.

The Critical Role of Cargo Surveys

For flat rack shipments, one key step is essential: the cargo survey. These surveys are a critical safety requirement governed by international maritime standards such as the IMO Code of Safe Practice for Cargo Stowage and Securing (CSS Code). Surveyors are licensed professionals who verify that cargo is properly secured for its sea voyage.

Their inspections go far beyond a quick visual check. They assess:

• The weight distribution of the cargo
• The strength and positioning of lashing points
• The adequacy of dunnage and securing methods
• Compliance with regulatory guidelines for maritime transport

These surveys produce detailed reports, complete with photographs, that serve as legal proof that the cargo was loaded and secured to an acceptable standard. This documentation becomes invaluable if a dispute or insurance claim arises later.

At ICE, we schedule these surveys as part of our end-to-end service, often engaging trusted survey partners at both origin and destination. For high-value or technically complex cargo, we also recommend “in-transit surveys,” which document the condition of the cargo as it is loaded, transported, discharged and finally delivered to its end location.

Insurance Protection: A Must for Large or Complex Shipments

Even with the best planning, the nature of ocean freight involves risk. Damage can occur during rough seas, handling incidents, or road transport after discharge. In such cases, the first call is to the marine insurer, who will dispatch their own surveyor to assess the damage, gather evidence, and begin the claims process.

Having pre-shipment survey reports strengthens any marine insurance claims by proving the cargo’s original condition. This is especially crucial for shipments involving:

• Machinery with sensitive components
• Crated goods where interior inspection is limited
• Multi-million-dollar assets such as yachts or industrial modules

A 2022 report from Allianz Global Corporate & Specialty (AGCS) noted that cargo damage remains the most frequent cause of marine insurance claims globally, accounting for over 50% of claims value. Thorough documentation can be the difference between a denied or fully-paid claim.

Cargo Safety: Who’s Responsible?

In Australia, the Chain of Responsibility (CoR) framework under the Heavy Vehicle National Law (HVNL) places legal obligations on all parties involved in the supply chain —from shippers to packers, transport operators and forwarders—to ensure cargo is loaded and transported safely on public roads.

When working with clients, we often collaborate with specialised packing companies who understand both international shipping standards and Australian domestic road regulations. Our vetted expert partners ensure that crates are built to handle forces during transit, lashings meet rated capacities, and cargo presents in a way acceptable to both carriers and road authorities.

For example, in one recent project, we worked with a client moving a large carton packing machine from the UK to Australia. Initial dimensions suggested the cargo wouldn’t fit in a standard container. Through collaborative planning with our UK partner and a specialised packing company, we found a way to partially disassemble and repack the machine, successfully fitting it into a 40ft High Cube container instead of an Open Top —saving significant freight costs and simplifying the process.

Freight Forwarders as Logistics Architects: Designing Complete Solutions

At ICE, we often say that freight forwarders are the architects of global trade. Much like an architect designs every detail of a building to ensure it stands strong and functional, we design logistics solutions that optimise delivery times, safeguard cargo integrity, and create seamless door-to-door journeys for international businesses.

Optimising Delivery Times

Shipping isn’t just about moving goods; it’s about timing. We use our deep knowledge of global shipping routes, carrier networks, port operations, and customs processes to design the most efficient transport plans. For businesses with time-sensitive inventory, delays can have huge financial impacts. Our role is to build logistics blueprints that get goods where they need to be, when they need to be there.

Protecting Cargo Integrity

The safety of your cargo is at the heart of everything we do. We carefully select packing materials, transport modes, container types, and even lashing systems to ensure goods arrive in the condition they left. Whether it’s refrigerated goods, fragile electronics, or heavy industrial machinery, we tailor protective strategies to each shipment.

Driving Cost Efficiency

Freight costs can make or break an international transaction. Through shipment consolidation, route optimisation, carrier negotiations, and customs consultancy, we help businesses unlock cost savings (example here) without sacrificing reliability. By having a complete in-house and Australian-based team, we also prevent costly delays caused by miscommunication between multiple providers.

Expert Customs Clearance Guidance

Customs regulations in Australia are constantly changing, notably becoming more complex in the past few years with new biosecurity and customs regulations added. Our fully licensed and in-house team provide expert customs consultancy and orchestrate clearances to ensure full compliance with biosecurity, tariff, and duty regulations. We help businesses prepare accurate documentation, manage permits, and provide advice to minimise clearance delays and avoid penalties.

Handling Large-Scale Project Movements

When businesses need to relocate entire production lines, move oversized machinery, or deliver critical infrastructure, we step in as full project cargo managers. We coordinate site assessments, packaging, route planning, crane lifts, marine insurance, and every stakeholder involved. Our oversight ensures these highly complex moves proceed safely and on schedule.

In short, as logistics architects, we don’t just move freight—we design holistic logistics systems tailored to our clients’ commercial needs. Our job is to make the complex simple, the uncertain certain, and the risky secure.

Why Experience Matters

Every shipment is unique. Some clients are seasoned shippers of project cargo; others may be relocating equipment internationally for the first time. Our role at ICE is to act as the client’s agent—guiding, advising, and coordinating every piece of the puzzle.

We conduct site visits, organise technical reviews, liaise with overseas partners, and provide clear communication throughout. Our aim is to prevent surprises and costly delays. If an issue arises, as a crate that can’t be safely lashed because the contents are not visible, for example, we have the expertise to resolve it, whether that involves modifying packaging, cutting inspection windows into crates, or working directly with the carrier’s technical team.

Why Early Engagement Is Essential

The earlier we can engage in the planning process, the better the outcome. Oversized freight involves a web of stakeholders—surveyors, carriers, transport companies, packing providers, biosecurity authorities, insurers—and aligning all parties early minimises the risk of delays or unforeseen costs.

International cargo is never a one-size-fits-all exercise. But with the right preparation, expertise, and communication, even the most complex project moves can proceed smoothly and safely.

Our experienced project cargo team is ready to help you navigate every stage of the process with precision, care, and complete peace of mind.
