SLB OneSubsea Awarded Major Umbilical Contract by Eni for Offshore Indonesia

SLB OneSubsea, a joint venture of SLB, has been awarded a contract by Eni North Ganal Limited to deliver a steel tube umbilical system for the Kutei North Hub field development project offshore East Kalimantan, Indonesia. Eni North Ganal Limited operates as a subsidiary of Searah Limited, which is a joint venture company established between Eni and PETRONAS.

Infrastructure Scale and Deepwater Specifications
The contract involves the engineering, procurement, and manufacturing of 94.6 km of steel tube umbilical designed to operate in water depths reaching up to 2,200 meters. The complete umbilical system has a total weight of approximately 6,700 tons.

The system is engineered to withstand a design pressure of 10,000 psi to support the deepwater field requirements. A specific technical parameter of the project includes the production of a single continuous umbilical section spanning 30 km and weighing approximately 2,100 tons. This large-scale component requires specialized carousel capacity for manufacturing and storage operations.

Parallel Manufacturing Technologies
SLB OneSubsea will execute the contract utilizing a parallel manufacturing configuration that combines its Oscilay™ and planetary production lines. This production method enables simultaneous manufacturing activities, increasing overall factory throughput and shortening delivery timelines compared to traditional single-line production sequences.

The manufacturing strategy is designed to accelerate product delivery while maintaining the required reliability metrics for high-pressure deepwater installations.
