ALOFT: Understanding Above Deck Shipping for Your Cargo

What Does ALOFT Mean in Freight Forwarding?

In the intricate world of global logistics, precise terminology is paramount. When you encounter the term "ALOFT" or "Above Deck" in relation to ocean freight, it refers to cargo that is stowed on the main deck of a vessel, rather than within the ship's holds. This seemingly simple distinction carries significant implications for cargo safety, cost, and suitability, making it a crucial consideration for businesses planning international shipments.

Ocean Cargo, with over 25 years of expertise in navigating complex supply chains, understands that choosing the right stowage location is a strategic decision. While most containerised cargo is typically stowed below deck for maximum protection, certain types of freight are routinely, or even necessarily, placed ALOFT. Understanding these nuances is key to ensuring your goods reach their destination safely and efficiently.

Why is Cargo Shipped ALOFT? Key Considerations

Shipping cargo above deck isn't a random choice; it's driven by a combination of practical, regulatory, and economic factors. Here are the primary reasons why cargo might be stowed ALOFT:

• Oversized and Out-of-Gauge (OOG) Cargo: This is perhaps the most common reason. Items that are too large to fit into standard containers or through the vessel's hatches – such as large machinery, industrial components, or yachts – must be placed on deck. Ocean Cargo specialises in project cargo logistics, expertly handling these challenging shipments.
• Hazardous Materials (HAZMAT): Certain classes of Dangerous Goods, particularly those that emit fumes, are highly flammable, or pose a significant risk in an enclosed space, are often required by international maritime regulations (IMDG Code) to be stowed on deck. This allows for better ventilation and easier access in case of an emergency.
• Ventilation Requirements: Some cargo, like certain chemicals or perishable goods, requires constant airflow to prevent spoilage or the build-up of dangerous gases. Above deck stowage provides superior natural ventilation compared to enclosed holds.
• Accessibility for Discharge: For ports with limited equipment or for cargo that needs to be discharged quickly, placing it ALOFT can facilitate easier and faster offloading, reducing port dwell times.
• Weight Distribution and Stability: In some cases, placing specific heavy items on deck can help with the overall stability and trim of the vessel, especially when dealing with unusual or unbalanced loads.
• Cost-Effectiveness: While not always the primary driver, in some scenarios, above deck space might be offered at a different rate, or it might be the only available option for a particular vessel or route.

Ocean Cargo's team provides consultative advice, helping you determine the most appropriate and compliant stowage solution for your specific cargo, whether it's sea freight to the USA or excavators and diggers to the UAE.

Risks and Challenges of ALOFT Shipping

While necessary for certain types of cargo, above deck stowage comes with inherent risks that must be carefully managed. Ocean Cargo prioritises risk mitigation and transparent communication to ensure peace of mind for our clients.

Increased Exposure to Elements

Cargo stowed ALOFT is directly exposed to the full force of the marine environment. This includes:

• Saltwater Spray: Constant exposure to corrosive saltwater can damage unprotected goods, leading to rust, degradation, or electrical failures.
• Extreme Temperatures: Fluctuations from intense sun exposure to freezing conditions can affect temperature-sensitive items.
• High Winds and Storms: Severe weather can exert immense pressure on cargo and its lashing, increasing the risk of shifting or loss overboard.
• UV Radiation: Prolonged exposure to ultraviolet rays can degrade certain materials, plastics, and coatings.

Greater Risk of Damage or Loss

The direct exposure translates to a higher probability of:

• Physical Damage: Impact from waves, shifting during rough seas, or contact with other cargo.
• Cargo Loss: In extreme weather, there's a non-zero risk of cargo being washed overboard, particularly if not adequately secured.
• Theft/Piracy: While less common on modern vessels, cargo on deck can theoretically be more accessible.

Insurance Implications

Due to the elevated risks, marine cargo insurance policies often have specific clauses or higher premiums for ALOFT cargo. It is imperative to declare above deck stowage to your insurer and ensure adequate coverage. Ocean Cargo can guide you through the insurance considerations for your customs and compliance needs.

Lashing and Securing Requirements

The lashing and securing of ALOFT cargo are critical. It must withstand extreme forces. This requires specialist knowledge and equipment to ensure compliance with international safety standards. Our project logistics team meticulously plans and oversees the securing of all above deck shipments, from wind turbine components to Australia to heavy machinery.

Mitigating Risks: Ocean Cargo's Approach to ALOFT Shipments

Despite the challenges, shipping ALOFT is a routine and safe practice when handled by experienced professionals. Ocean Cargo employs a rigorous approach to minimise risks and ensure the secure transit of your above deck cargo:

1. Expert Planning and Assessment: Every ALOFT shipment begins with a detailed assessment of the cargo's nature, dimensions, weight, and specific requirements. We consider the route, potential weather conditions, and vessel capabilities.
2. Specialised Equipment and Lashing: We utilise robust lashing materials, custom cradles, and securing techniques designed to withstand the harshest marine conditions. Our partners are experts in heavy-lift and OOG cargo securing.
3. Protective Packaging: We advise on and facilitate appropriate protective packaging, such as shrink-wrapping, tarpaulins, or corrosion inhibitors, to shield cargo from saltwater, UV, and other environmental factors.
4. Comprehensive Insurance Advice: Ocean Cargo works with clients to ensure they have the correct and adequate marine cargo insurance coverage for ALOFT shipments, providing peace of mind against unforeseen events.
5. Vessel Selection: We select vessels that are best suited for above deck cargo, considering deck strength, stability, and available securing points.
6. Real-time Tracking and Communication: Our clients benefit from continuous updates and transparent communication throughout the shipping process, allowing them to monitor their cargo's journey.
7. Compliance with Regulations: We ensure strict adherence to all international maritime regulations, including the IMDG Code for hazardous materials and the CTU Code for cargo securing.
