FabricAir Duct Systems Installed in Offshore Installation Vessel

Why Fabric Duct is Ideal for Offshore Applications

The challenging environmental conditions of offshore operations require HVAC systems that can withstand high moisture, salt, and corrosion while maintaining optimal air distribution and indoor air quality. FabricAir ducts were chosen for the Boreas because they offer several advantages over traditional metal ductwork. Fabric ducts are lightweight, resistant to corrosion, and help eliminate condensation, a crucial factor in maintaining safe and clean air in areas where moisture can be a persistent issue. The flexibility of fabric ducts also allows for easy customization in confined or irregular spaces, which is often the case on ships. Additionally, FabricAir’s systems are easy to install and maintain, reducing operational downtime, which is a significant benefit in an industry that operates under tight schedules.

FabricAir System Components Used in the Boreas

In the design of the Boreas’ HVAC system, FabricAir ducts were installed in multiple critical areas, including the Engine Control Room (ECR) and the electrical equipment rooms.

Engine Control Room (ECR)

• • Ceiling Type: Closed ceiling
  • Duct Profile: The low-profile D-shaped/half-round duct design was selected to fit within the limited headroom of the ECR while maintaining efficient airflow. This configuration allows the duct to attach directly to the hard ceiling, maximizing space and minimizing interference with the vessel’s operations.
  • Fabric: Combi 20 is a flame-retardant, permeable fabric that is Oeko-Tex 100 certified. Its durability and resistance to wear, combined with machine washability and a 5-year warranty, make it ideal for high-performance environments like the Boreas.
  • Flow Model: SonicFlow directs air through laser-cut perforations along the duct, providing precise and uniform air distribution throughout the ECR, which is crucial for maintaining a controlled temperature and clean air environment.
  • Suspension: The Type 11A suspension system allows for easy and efficient installation. The RapidSlider system ensures the duct can be slid into place seamlessly, minimizing labor and installation time while providing a sleek, continuous look.

Electrical Equipment Rooms

• • • Ceiling Type: Open ceiling with electrical equipment boxes
    • Duct Profile: Round duct
    • Fabric: Combi 20
    • Flow Model: As in the ECR, the SonicFlow model ensures effective and consistent airflow distribution across the electrical rooms, helping maintain temperature and air quality in areas filled with sensitive electronic equipment.
    • Suspension: Type 1 Cable Suspension with All-In-One shape retention is a cost-effective suspension system is designed for long, straight duct runs. The All-In-One shape retention ensures the ducts maintain their round shape even when the HVAC system is off, preserving airflow efficiency and a professional aesthetic.

The installation of FabricAir’s advanced fabric duct system on Van Oord’s Boreas vessel has proven to be a smart solution for managing airflow and indoor air quality in offshore environments. By combining lightweight, corrosion-resistant materials with efficient and customizable air distribution, FabricAir has delivered a system that meets the vessel’s stringent operational requirements while ensuring a safe and comfortable environment onboard. The successful implementation of FabricAir’s solutions on the Boreas highlights the versatility and performance of fabric ducts in even the most challenging marine applications.
