Fuel loading and unloading can create serious safety, environmental, and operational challenges. From flammable vapours to product spills, even a routine transfer can become risky, especially if you don’t have the right equipment.
That’s why more and more site managers are investing in proper safety systems, such as loading arms with integrated vapour recovery. These systems help capture displaced vapours during loading or unloading, reducing emissions and helping protect operators, equipment, and the environment.
A vapour recovery system is a closed-loop configuration designed to capture hydrocarbon vapours that are displaced or released during the transfer of volatile liquids.
These systems are used across a wide range of industries, from petroleum terminals and chemical plants to food and beverage facilities and gas stations. In every application, the goal is the same: keep Volatile Organic Compounds (VOCs) out of the air.
How Do Vapour Recovery Systems Work?
In the context of tanker truck loading and unloading, the basic principles of vapour recovery systems are simple. The process unfolds in three stages:
1. Vapour Capture When the loading arm connects to the tanker truck, a vapour recovery coupler or hose creates an airtight seal at the connection point. As product flows in, displaced vapours are drawn into the vapour return circuit rather than escaping through the fill opening.
2. Vapour Transfer The captured vapours travel back through the loading arm’s vapour return line, either via a piggyback hose welded to the product arm, or through a dedicated second arm in a dual-arm configuration.
3. Vapour Recovery and Re-use At the receiving end, captured vapours are processed — either returned directly to the product storage tank, compressed and condensed back into liquid form, or fed into a vapour combustion or treatment unit.
The end result is a closed system: product flows in, vapours flow back, and nothing escapes to atmosphere during normal operation.
Benefits of Vapour Recovery Systems
More and more operations managers are adding vapour recovery systems to their tanker truck loading systems. Here’s why:
Environmental Impact
Hydrocarbon vapours released during fuel loading are composed primarily of volatile organic compounds (VOCs). Canada’s Canadian Environmental Protection Act (CEPA) establishes regulations on VOC emissions from fuel loading and storage operations, and provincial regulators in Alberta and BC have their own emissions requirements for petroleum handling facilities. Vapour recovery systems capable of capturing upwards of 95% of displaced vapours are required by these regulations.
Worker Safety
Displaced vapours can also be dangerous for workers. Without vapour recovery, operators can be exposed to a cloud of flammable vapour throughout the loading process, which creates a serious hazard.
A sealed vapour recovery system eliminates that exposure at the source. Workers on the loading platform aren’t breathing displaced product vapours and fire hazards are substantially lowered. For sites already managing fall protection, PPE requirements, and emergency shutoff systems, vapour recovery is an important piece of the overall site safety picture.
Operational Efficiency
The right vapour recovery system can also reduce time on the loading rack. At Northern Platforms, we use OPW’s Drylok™ Vapour Recovery Technology, which helps reduces the average time to connect a loading arm to railcar valves to 35–40 seconds. Operators simply turn a lever to connect; no pipe wrenches, cheater bars, or hammers required. That reduction in connection time adds up fast across a high-volume loading operation.
Vapour Recovery in Tanker Truck Loading and Unloading
At Northern Platforms, we use OPW Engineered Systems products to offer two primary vapour recovery loading arm configurations:
Piggyback Style Arm A simpler and more compact design where the vapour return line is welded directly to the product loading arm. The vapour hose runs parallel to the arm structure and connects at the dome hatch alongside the product drop tube. This configuration works well for lower-volume applications or sites where space at the loading rack is limited.
Dual Arm / Siamese Configuration The more commonly specified design for higher-volume or more demanding applications. This configuration uses two separate loading arms, one for product transfer and one for vapour recovery, joined together at the inner boom structure so they operate as a single, counterbalanced unit. The dual arm arrangement provides better flow capacity for the vapour return circuit and is the preferred setup for most fuel terminal and petroleum loading applications.
In addition to core system design, Northern Platforms offers a range of customization options to match the specific demands of your product and operating environment, including steam jacketing, heat tracing, insulation packages, and specialized couplings. Contact us with your site requirements, and we can recommend the right configuration for your operation.

Alberta operators count on railcar loading arms to perform crucial tasks within their operations. But here’s what they forget: without proper maintenance and inspection, these systems could fail right when you need them most. Are you overdue for loading arm maintenance? Keep reading to learn more about this essential service–and how to book an appointment with Northern Platforms today.
Loading arm maintenance involves a combination of routine visual inspections, lubrication of swivel joints and moving assemblies, seal checks, and counterbalance adjustments. Most equipment manufacturers outline specific maintenance requirements in their installation, operation, and maintenance manuals, and staying on top of these tasks is often a condition of your warranty coverage.
The goal is simple: keep your loading arms operating smoothly and catch minor issues before they turn into major, costly problems. When maintenance is performed on a regular schedule by a trained team, your loading arms will last longer, perform better, and help keep your workers safe.
What are the Benefits of Preventative Maintenance?
We’ve discussed the main benefit of preventative maintenance in a previous blog post, but to recap: scheduled inspections and maintenance on your truck and railcar loading systems will save you money in the long run. Proactive repairs often cost substantially less than complete system replacements.
In addition to cost savings, there’s another major benefit that often gets overlooked: time savings for your team. Outsourcing inspections and maintenance to a team like Northern Platforms leaves more time for facility managers to focus on efficiency, safety requirements, and ensuring their operation is running smoothly.

When it comes to fuel tanker unloading equipment, dry disconnects have become essential for modern loading and unloading operations. These systems automatically shut as soon as your hose or loading arm is disconnected, which helps prevent spills and increases the overall safety of your site. At Northern Platforms, we specialize in turnkey fuel tanker loading and unloading equipment that integrates seamlessly into your site. In this guide, we’ll walk you through how dry disconnects work, the key equipment you need, and why they are a smart investment for your operation.
What are Dry Disconnects?
Dry disconnect couplings automatically shut off product flow when disconnected, helping to eliminate even the smallest spills. Unlike traditional couplings that release residual product into containment areas, dry disconnects retain any remaining fuel inside the connector itself. This means:
No fuel spills onto the ground
No product drips onto equipment or personnel
No vapour releases during disconnection
No cleanup required between unloading cycles
The retained product typically remains in the coupler and is removed during the next connection, or it can be drained safely during maintenance.

Ready to create the ideal fuel tanker loading and unloading system from top to bottom? This blog post will walk you through all the essential equipment you’ll need. Plus, keep reading for some key considerations and featured manufacturers.
Essential Equipment for Fuel Tanker Loading
Bottom Loading Arms
Looking for the best fuel tanker loading equipment? The answer is simple: invest in a bottom-loading arm. While many operations count on top-loading technology, bottom-loading is superior for fuel-specific uses. When a fuel tanker is loaded from the bottom, it creates less turbulence. This helps reduce static build-up and significantly minimizes fire risks.
An added benefit? Bottom loading allows workers to safely load and unload product from the ground— completely eliminating falling risks or other hazards from working at height.
Hoses
While most industry professionals recommend loading arms over hoses, this tried-and-true loading system still has its place. Generally speaking, hoses are a great choice for simpler operations or businesses with limited budgets. When choosing your hose assembly, pay attention to material compatibility, temperature ranges, and pressure ratings.
Breakaway Couplings
Accidents can happen in even the most ideal circumstances. When you invest in breakaway couplings for your fuel tanker loading system, you are protecting your operation and your workers from any incident that accidentally causes your loading arm or hose to dislodge from the tanker while loading. If your vehicle moves unexpectedly, this device will automatically shut off the fuel flow, protecting you from catastrophic spills.
API Couplers
Another essential piece of fuel tanker loading equipment? API Couplers to help ensure secure connections and reduce operator error. These connections will only open when properly engaged, helping prevent small spills when your hose or loading arm is disconnected. Pair these with breakaway couplings for complete protection.
Spill Containment
While most fuel tanker sites have spill containment pads built into their sites, you can ensure complete protection with additional containment products from Northern Platforms. With portable containment berms, pads for oil drums, and more can compliment your permanent infrastructure to ensure your site is 100% compliant and protected at all times.
Considerations for the Best Fuel Tanker Loading System
When selecting your fuel tanker loading equipment, there are many questions you should ask yourself, including the following:
What types of trucks do you deal with?
How many trucks do you deal with?
What are the environmental considerations of your site?
What tanker truck configurations does your system need to accommodate?
What are your flow rate and capacity requirements?
Still not sure what kind of system is right for you? Contact the experts at Northern Platforms to walk through your options.

Northern Platforms offers a wide selection of trusted and ergonomic bottom-loading arms from established brands like OPW Engineered Systems and EMCO Wheaton. Ready to integrate bottom-loading arms into your operation? Let’s go over some key things to consider before you make this purchase.
What are Bottom Loading Arms?
As the name suggests, bottom loading arms are used when loading from the bottom and should be paired with trucks or railcars that accommodate a bottom loading configuration.
Bottom-loading arms are a safer and more efficient alternative to hoses. Read more about the difference between hoses and loading arms in our previous post: “Hoses vs Loading Arms: Which Works Best?”
Here are some more advantages of bottom-loading arms:
Operator safety: Workers remain on the ground, which reduces fall risks.
Faster loading: Quicker connections and the ability to load multiple compartments at the same time.
Less turbulence: The process generates less turbulence in the tank, which helps lower static generation.
Less vapours: Fewer vapours are released, which helps lessen the environmental impact.
More cost-effective: Typically, these systems are easier and cheaper to build than top-loading arms.
Key Considerations for Choosing Bottom Loading Arms
There are several factors to consider when choosing your bottom loading arm. It is essential to consider your existing operation to ensure that you can find the right equipment for you.
If you aren’t sure where to start, contact Northern Platforms, and we will be happy to help you find a loading configuration that integrates seamlessly into your existing operation.
What type of fluid are you handling?
First, it is important to ensure that the materials of your bottom loading arm are compatible with the fluid you are moving.
For example, if you are moving corrosive substances, you will want to ensure that your bottom loading arms are made of a corrosion-resistant material like stainless steel. However, if you are moving non-hazardous materials, you could use carbon steel, which is often cheaper and lighter.
What type of vehicle are you loading?
Whether you are loading a tanker truck or a railcar, the type of vehicle you are loading affects the design of your bottom loading arms. Keep in mind that different vehicles have specific connection points and height requirements. Make sure to choose an arm that can easily reach and securely connect to your vehicle to avoid leaks and operational issues.
What is your loading environment like?
Your loading environment can significantly impact the type of loading arm you need. Consider: is there existing equipment that would interfere with your loading arm? Do you need an operation that is suitable for outdoor use? Are there other environmental factors you should consider, like extreme temperatures or exposure to hazardous chemicals?
What additional safety equipment do you need?
While bottom loading arms are a good start, there are always ways to make your site safer and more efficient. At Northern Platforms, we offer extra safety equipment to help ensure that your loading system operates smoothly and safely.
