SLB OneSubsea has been awarded a major contract by Eni North Ganal Limited to supply a 94.6-kilometer steel tube umbilical system for the Kutei North Hub development in Indonesia. The project represents one of the industry's largest umbilical orders by weight, utilizing advanced parallel manufacturing techniques.
SLB OneSubsea, a joint venture under global energy technology giant SLB, has secured a contract from Eni North Ganal Limited to engineer and manufacture a comprehensive steel tube umbilical system. The infrastructure is destined for the Kutei North Hub field development project, located offshore East Kalimantan, Indonesia. SLB operates as a global technology firm specializing in energy innovation, decarbonization, and subsurface characterization across international oil and gas markets.
The agreement outlines the delivery of 94.6 kilometers of umbilical cabling designed to operate at extreme water depths reaching up to 2,200 meters. The total system weight is projected at approximately 6,700 tons, featuring a specialized 30-kilometer continuous segment weighing 2,100 tons that requires large-scale carousel storage. According to official disclosures, the infrastructure is engineered to withstand a design pressure of 10,000 psi. Production will leverage parallel manufacturing lines to accelerate traditional delivery timelines.
This development underscores a accelerating momentum in deepwater oil and gas investments within the Asia-Pacific region, particularly as operators target more technically challenging reserves. By deploying advanced manufacturing methods that bypass conventional single-line limitations, the project establishes a new benchmark for supply chain efficiency in ultra-deepwater engineering.
For energy investors and supply chain strategists, the contract highlights the critical role of specialized subsea infrastructure vendors in mitigating project delays. As deepwater exploration expands in Southeast Asia, the capability to manufacture high-pressure, heavy-tonnage systems at scale will remain a decisive competitive differentiator for oilfield service providers navigating complex marine environments.
