As part of our ongoing work in the Middle East, HC recently completed the delivery of a pressurized explosion-proof laboratory cabin for a well testing project in the United Arab Emirates. The customer required a compact, reliable, and safe workspace that could be deployed directly at the wellsite, particularly for high-pressure and sour-gas wells. After several rounds of engineering refinement and technical discussions, the customized cabin was successfully fabricated, tested, and shipped to the site.

The delivered unit adopts a fully welded steel structure with an explosion-proof coating, ensuring durability under the UAE’s challenging field conditions, including high temperatures, sand exposure, and H₂S-rich environments. Inside the cabin, the space is organized into two independent sections.

The operation area provides a safe working environment for technicians, featuring adjustable explosion-proof desks and chairs, integrated lighting, and essential communication interfaces.

The equipment area is fitted with an explosion-proof electrical cabinet equipped with a PLC control system, a complete monitoring sensor array, and an emergency power interface. Together, these systems support real-time environmental monitoring and stable operation of field testing equipment.

One of the key highlights of the cabin is its positive-pressure protection system. By continuously supplying clean, dry air at 25–150 Pa, the system maintains a stable positive-pressure barrier that prevents methane, hydrogen sulfide, and other flammable gases from entering the workspace. This design significantly enhances safety for personnel working near sour wells. A pressure interlock mechanism is also integrated to ensure that if sufficient pressure is not established, all electrical equipment will automatically remain in a locked state—preventing unsafe operation and achieving true fail-safe protection.

To meet the customer's deployment needs, the cabin incorporates a modular design that allows rapid assembly, relocation, and expansion. Ventilation openings and air-supply interfaces are pre-installed on the roof, making it easy to connect the cabin to the external air source system once it arrives on-site. This greatly shortens installation and commissioning time and aligns well with the fast-paced testing workflows commonly used in the region.

The successful delivery of this project reflects HC’s engineering competence and experience in supplying reliable safety-critical equipment for international oilfield operations. We remain committed to supporting our global clients with solutions that improve field safety, operational continuity, and testing efficiency.

HC will continue to strengthen our presence in overseas markets and provide high-quality, field-proven oilfield process equipment for well testing, early production facilities, and other surface applications.
