Objective

Aurora supported its valued client in the delivery of subsea structures for an Enhanced Oil Recovery (EOR) project. The scope included the fabrication and handling of multiple Subsea Umbilical Distribution Structures (SUDS), riser bases and pile pipes. The works demonstrated Aurora’s capability to execute large-scale, heavy subsea fabrication with precision, efficiency and a strong commitment to safety. The objective was to fabricate, assemble and deliver subsea structures and piling for the EOR project, ensuring strict compliance with dimensional, weight and quality specifications to support safe offshore installation.

Challenges

The project required precise fabrication and handling of very large and heavy subsea structures, demanding careful coordination of lifting operations, specialist logistics and strict adherence to tolerances and offshore specifications.

Solution

Aurora delivered a comprehensive engineering and fabrication package that included:

Subsea Structures – Fabrication of multiple SUDS structures, including:
- Area D SUDS (32 tonnes, 6m × 6m × 3.8m)
- Area E SUDS (32 tonnes, 6m × 6m × 3.8m)
- Riser Base SUDS (34 tonnes, 6m × 10m × 3.7m)

• Pile Pipes – Fabrication of 8 × pile pipes, each weighing 10.5 tonnes and measuring 28.8m in length with a 0.6m diameter.

• Delivery & Support – Coordination of heavy lift handling, coating, and transportation to support offshore installation.

Value to Client

Aurora provided significant value through:

Precision Fabrication – All subsea structures manufactured to exacting standards, ensuring offshore installation readiness.

Safe Execution – Complex heavy lifts and handling completed without incident.

Efficient Delivery – On-time completion of all structures and pile pipes, enabling seamless project integration.

Trusted Partnership – Supported the client in delivering critical subsea infrastructure for the EOR development.
