Sarens Completes Heavy Lifting Campaign at Algeria’s Tinrhert Gas Fields

30 Second Takeaway

Sarens has successfully completed a major heavy lifting campaign in Algeria’s remote southeastern desert, supporting the development of the Tinrhert gas fields at Alrar. Awarded by Petrofac on behalf of Sonatrach, the project involved installing critical gas infrastructure components under extreme environmental and logistical conditions, with operations carried out between March and July 2025.

Supporting a Strategically Important Gas Development

Sarens has delivered a complex heavy lifting scope at the Tinrhert gas fields in Alrar, located

in Algeria’s southeastern desert. The contract, awarded by Petrofac on behalf of national energy company Sonatrach, forms part of the EPC2–Lot1 development package and supports a nationally significant gas project.

Operations were executed between March and July 2025 in one of the region’s most remote environments, requiring detailed planning, robust equipment selection, and strict safety controls.

Heavy Lift Scope and Site Challenges

Extreme Conditions in a Remote Desert Location

The project involved the installation of 11 heavy components essential to the site’s gas infrastructure. Work was carried out under challenging conditions, including confined working areas, temperatures exceeding 50°C, frequent sandstorms, and complex logistics linked to the isolated location.

Sarens’ scope required careful coordination to ensure progress despite environmental constraints and limited access to on-site resources.

Crane Configuration and Mobilisation

Long-Distance Transport and On-Site Assembly

Key equipment deployed for the campaign included a 600-tonne CC-2800 crawler crane, configured with a 54-metre main boom, supported by an AC-140 crane.

Both cranes were transported overland from Sarens’ base in Oran, covering approximately 1,600 kilometres in journeys lasting up to 10 days. Once on site, crane assembly required a further 10 days, highlighting the logistical complexity of operating in remote desert conditions.

Critical Lifts and Precision Execution

Fire Water Tank Roof Installation

The main lift of the campaign focused on the installation of the fire water tank roof, an 88.9-tonne structure lifted at a 30.9-metre radius.

Due to limited available space, the CC-2800 was required to perform slewing and crawling movements while carrying the load to achieve precise positioning. This operation was supported by detailed lift planning, real-time coordination, and strict safety procedures to ensure controlled execution.

Health, Safety, and Environmental Controls

Maintaining Safety in Harsh Conditions

Sarens implemented intensive health, safety, and environmental (HSE) measures throughout the project. These included stability planning for sandy ground conditions, dust and heat protection measures, structured hydration protocols for personnel, and continuous mechanical support to ensure uninterrupted operations.

These controls were critical in maintaining safety standards while sustaining productivity in extreme temperatures.

Ongoing Works and Future Lifts

Continued Mobilisation for Upcoming Scope

The Tinrhert gas fields project is ongoing. Sarens has recently mobilised an additional 400-tonne Terex Demag CC2400-1 crawler crane to support upcoming lifts, including the installation of two columns weighing 411 tonnes each.
