Tenaris Invests $10m In Onne Plant To Strengthen Nigeria’s Local Oilfield Capacity

By Ayo Susan

Tenaris Global Services has invested approximately $10 million in upgrading its thermal insulation plant at the Federal Lighter Terminal, Oil and Gas Free Zone, Onne, Rivers State, commissioning what it describes as sub-Saharan Africa’s only five-layer thermal insulation coating line. The milestone, marked alongside the completion of the Bonga North deepwater oil project’s pipe-coating campaign and 25 years of Tenaris’ Nigerian operations, reinforces local manufacturing capacity. Managing Director of Tenaris in Nigeria, Rosario Osobase, said that the investment supports local expertise, while Minister of State for Petroleum Resources (Oil), Dr. Heineken Lokpobiri, stressed consistent implementation of local-content legislation.

DECISION HIGHLIGHT

The investment strengthens Nigeria’s capacity to execute specialised pipe-coating work locally, but sustained industrial benefits depend on a reliable pipeline of oil and gas projects.

DECISION MEMO

Tenaris’ Onne upgrade represents more than additional industrial equipment: it preserves specialised capability in a market where reduced project activity between 2014 and 2023 led several pipe companies to close and engineering, procurement and construction firms to exit.

Osobase said that the investment reflected a long-term commitment to Nigeria’s energy industry through “investment, innovation and the development of local expertise”. Commercial Vice President for Sub-Saharan Africa, Europe and Caspian Sea, Alessandro D’Angelo, similarly warned that “continuity of investment and project activity will be critical to strengthening local value creation”.

The Bonga North campaign provides evidence of domestic execution capacity. Senior Director, Commercial, Sub-Saharan Africa, Juan Juanicotena, said completion on schedule demonstrated Nigeria’s ability to meet demanding technical standards and positioned the country for potential projects including Bonga Southwest, Obodo and Zabazaba.

Tenaris also reported supplying more than 20,000 tonnes of oil country tubular goods over the past decade for legacy Shell assets now operated by Renaissance Africa Energy Company. Through its subsidiary, Pipe Coaters Nigeria Limited, it has also participated in Nigerian gas pipeline projects.

Lokpobiri commended the company’s decision to remain in the country, stating: “Tenaris did not leave.” He linked investment retention to consistent implementation of local-content legislation and the preservation of skilled jobs. Special Adviser to the President on Oil and Gas, Olu Verheijen, also cited Tenaris’ infrastructure and workforce investments as evidence of confidence in Nigeria.

The strategic test is whether this installed capability attracts repeat contracts, deeper supplier participation and sustained skills development. Without predictable project activity, advanced local facilities may remain underutilised despite their technical significance.

DATA BOX

• Investment: Approximately $10 million.
• Location: Onne, Rivers State.
• Facility: Five-layer thermal insulation coating line, described by Tenaris as the only one of its kind in sub-Saharan Africa.
• Project completed: Bonga North deepwater oil project pipe-coating campaign.
• Operating history: 25 years in Nigeria.
• Historical supply: More than 20,000 tonnes of oil country tubular goods over the past decade for legacy Shell assets.
• Potential future projects: Bonga Southwest, Obodo and Zabazaba.

WHO WINS / WHO LOSES

Potential winners: Nigerian oilfield workers, local suppliers, project operators and the domestic industrial ecosystem if the facility secures sustained utilisation.

Potential losers: Local manufacturers and skilled workers if project delays or weak contract continuity undermine investment returns and employment.

POLICY SIGNALS

Local-content policy must translate into predictable project pipelines, enforceable domestic participation and sustained workforce development, rather than compliance alone.

INVESTOR SIGNAL

The upgrade indicates confidence in Nigeria’s oilfield services market and strengthens specialised local capacity. Commercial returns will depend on contract awards, utilisation rates and continuity of upstream investment.

RISK RADAR

Key risks include project delays, insufficient demand, policy inconsistency and underutilisation of specialised equipment. The next test is whether Bonga North’s completion leads to repeat work and broader domestic value creation.
