Engineered for Extreme Conditions: Heavy-Duty Desert Trailer in Oman

We partnered with Ensign International Energy Services LLC to design and fabricate a bespoke heavy-duty trailer for transporting generator sets across challenging desert environments in Oman.

Delivered from our Nizwa facility, this project required a solution capable of handling extreme loads, harsh terrain, and strict regulatory requirements, while ensuring safe and efficient movement between well locations.

We delivered a fully engineered and fabricated trailer solution, managing the project end-to-end from design and approvals through to fabrication and testing.

The scope included:

• Complete engineering design and structural analysis
• Fabrication and assembly of the trailer
• Integration of axle systems, hydraulic power unit (HPU), and braking systems
• Full electrical and safety systems in line with Oman regulations
• Coordination of regulatory approvals and certifications

Key Technical Features

• Maximum gross weight: ~180 tonnes
• Axle system: 180T load rating @ 10 km/h
• Hydraulic system: Double-acting cylinders with 210 bar working pressure
• Braking system: Dual-line air braking with ASME-certified air vessels
• Tyres: Nine sets of 26.5R25 for heavy-duty terrain performance
• HPU: 20 HP integrated diesel-powered hydraulic unit
• Compliance: Fully aligned with Oman transport regulations and field operator standards

The project was delivered through close collaboration with the customer at every stage.

From initial engineering through to final assembly, we worked alongside Ensign to ensure alignment on:

• Design specifications
• Fabrication quality
• Testing and inspection milestones

Key stages included:

• Engineering design approvals
• Fabrication and structural assembly
• Black mock-up validation
• Final assembly and inspection witnessed by the customer and regulatory authorities

Despite the complexity and scale, we delivered the project, demonstrating our ability to manage large, custom-engineered solutions efficiently.

The completed trailer provides Ensign with a safe, reliable, and efficient transport solution for heavy generator sets in desert operations.

• Safe and compliant transportation of heavy equipment
• Reliable performance in harsh desert conditions
• Full compliance with Oman regulatory standards
• Improved operational mobility between well locations

Driving In-Country Value in Oman

Delivered from our Nizwa facility, this project supports Oman’s In-Country Value (ICV) objectives by leveraging local engineering, fabrication capabilities, and supply chains.

Through close collaboration with local teams and stakeholders, we contributed to developing in-country expertise while ensuring full compliance with national standards and regulations. This approach strengthens local capability while maintaining the highest levels of engineering quality and performance.

This project highlights our strength in delivering complex, custom-engineered solutions under demanding conditions, ensuring long-term operational confidence.

Key differentiators included:

• Proven engineering expertise for heavy-load applications
• Strong local and regulatory compliance knowledge in Oman
• Ability to manage end-to-end delivery, from concept to certification
• Trusted relationship with the customer
