Project Overview
In today’s rapidly evolving construction and housing sector, modular homes are becoming a preferred solution for developers, contractors, and private buyers worldwide. Their advantages—such as fast installation, cost efficiency, and mobility—make them ideal for international projects.
This case study highlights how Freights Logistics successfully managed the international transportation of a 42 square meter modular house using a 1×40FT Flat Rack (40FR) container, overcoming out-of-gauge (OOG) challenges and ensuring safe, timely delivery.
Shipment Details
- Cargo: Modular House Unit
- Container Type: 1×40FR (Flat Rack Container)
- Dimensions:
- Length: 11.5 meters
- Width: 3.6 meters
- Height: 3.6 meters
- Total Weight: 10 tons
- Cargo Type: Oversized / Out-of-Gauge (OOG)
Understanding the Cargo: Modular Container House
Modular houses are prefabricated structures manufactured in factories and transported to site for assembly. This “factory-to-site” model significantly reduces construction time and cost while maintaining high quality.
Unlike standard container homes that fit within ISO container dimensions, this shipment featured a custom-built oversized modular unit with a width of 3.6 meters—exceeding the standard container width of approximately 2.35 meters.
Because of this, the cargo could not be loaded into a standard 40HQ or 40GP container and required a specialized logistics solution.
Key Challenge: Out-of-Gauge (OOG) Transportation
Why Standard Containers Were Not Suitable
Standard container shipping (FCL) is typically used for modular units that fit within ISO dimensions. However, oversized units require alternative solutions.
In this case:
- Width exceeded standard limits
- Height approached maximum transport thresholds
- Structure could not be disassembled further
Solution: 40FT Flat Rack Container
A 40FT Flat Rack (40FR) container was selected because:
- It allows cargo to exceed width and height limits
- No side walls, enabling flexible loading
- Suitable for heavy and oversized cargo
- Provides strong base support for structural units
Flat rack containers are commonly used for modular homes and large equipment that do not fit into standard containers.
Logistics Planning & Execution
Transporting oversized modular housing requires detailed planning across multiple stages. Freights Logistics implemented a structured approach:
1. Pre-Shipment Engineering Assessment
Before shipment, our team conducted:
- Cargo dimension verification
- Center of gravity analysis
- Structural reinforcement check
- Lifting point identification
This step ensured safe handling during loading and unloading.
2. Packing & Securing the Modular House
Unlike containerized cargo, OOG shipments are exposed to external conditions. Therefore, proper protection and securing methods are critical.
Protective Measures:
- Heavy-duty waterproof tarpaulin wrapping
- Corner protectors to prevent structural damage
- Anti-corrosion coating for exposed steel parts
Lashing & Securing:
- High-tensile steel lashing belts
- Chain lashing with tensioners
- Wooden blocking for base stabilization
Proper lashing is essential to prevent cargo movement during ocean transit.
3. Port Operations & Loading
Loading Method:
- Crane lifting operation
- Direct placement onto flat rack
- Alignment based on weight distribution
Key Considerations:
- Even load distribution across container base
- Avoiding structural stress points
- Compliance with port safety regulations
Because the unit weighed 10 tons, it was well within flat rack payload limits, but required precise handling due to its size.
4. Ocean Freight Arrangement
Freights Logistics selected a suitable carrier offering:
- OOG cargo handling capability
- Competitive freight rates
- Stable sailing schedules
Shipping Mode:
- Breakbulk / OOG container shipping
- Deck or under-deck placement depending on vessel
Additional Surcharges:
- OOG surcharge
- Lashing and securing fees
- Port handling charges
Despite higher costs than standard FCL, flat rack shipping remains the most efficient solution for oversized modular units.
5. Customs Clearance & Documentation
Efficient customs clearance is crucial for avoiding delays.
Key Documents:
- Commercial Invoice
- Packing List
- Bill of Lading
- Certificate of Origin
- HS Code classification for modular structures
Freights Logistics ensured compliance with destination country regulations, especially for prefabricated housing units.
6. Destination Handling & Final Delivery
Upon arrival, the cargo required:
- Heavy crane unloading
- Special truck (low-bed trailer) for inland transport
- Site access planning
Because modular homes are designed for relocation, they can be quickly installed after delivery, reducing project timelines significantly.
Key Challenges & How We Solved Them
Challenge 1: Oversized Dimensions
Solution: Use of 40FR container with customized lashing plan
Challenge 2: Weather Exposure
Solution: Full tarpaulin protection and waterproof sealing
Challenge 3: Transport Stability
Solution: Advanced lashing and weight distribution strategy
Challenge 4: Port Handling Complexity
Solution: Pre-coordination with terminal and crane operators
Advantages of Modular House Shipping
This project demonstrates why modular housing is gaining global popularity:
1. Fast Deployment
Modular homes can be installed within days after delivery.
2. Cost Efficiency
