Seadrill

John Fredriksen, through his private investment vehicle Hemen Holding, is Seadrill's largest and controlling shareholder. Fredriksen is a Norwegian-born shipping magnate whose maritime empire spans crude tankers (Frontline), dry bulk carriers (Golden Ocean), and liquefied natural gas shipping (Flex LNG). His investment style involves consolidating capital-intensive industrial assets into publicly traded vehicles where he maintains board influence. Hemen Holding's stake in Seadrill was approximately 16% following the 2022 restructuring, making it the single largest voting bloc.

Seadrill filed for Chapter 11 bankruptcy protection in February 2021 and emerged in February 2022 after reducing total liabilities by approximately $4.5 billion. The restructuring converted significant debt into equity, raised $350 million in new capital, and streamlined the rig fleet through sales and scrapping. Operationally, the company emerged with a 10-rig owned fleet, a reduced cost structure, and a clean balance sheet with net debt of roughly $500 million — positioning it to benefit from the offshore drilling upcycle that began in 2023.

Brazil, West Africa, and the US Gulf of Mexico are Seadrill's primary revenue-generating regions. Brazil's pre-salt Santos Basin is a cornerstone market, where Seadrill has held multi-year contracts with Petrobras for its deepwater floaters. Angola and Nigeria contribute through long-standing relationships with international operators and national oil companies. The Gulf of Mexico provides shorter-cycle well-based work. Southeast Asia and the Middle East represent secondary markets served through managed rigs and joint ventures.

Seadrill primarily owns and operates its fleet, controlling 10 rigs directly as of 2025. Additionally, Seadrill Management, a subsidiary, provides rig management services for third-party owners, generating fee-based revenue without balance sheet exposure. This split structure allows the company to monetize operational expertise while keeping owned-asset capital allocation disciplined. The management arm has handled rigs in Qatar and Malaysia for national oil company clients.

Seadrill operates as an independent publicly listed company with its own board and management team, but John Fredriksen's Hemen Holding exerts significant influence as the controlling shareholder. Cross-ownership and interlocking directorates with other Fredriksen entities are limited compared to the pre-restructuring era. Seadrill's chief executive officer, Simon Johnson, was appointed in 2023 and reports to an independent board that includes directors from Maersk Drilling and Rowan Companies backgrounds. Related-party transactions are disclosed and reviewed under Norwegian corporate governance standards.

Seadrill operates a smaller, younger fleet post-restructuring, with 10 owned rigs skewed toward high-specification harsh-environment floaters and modern jack-ups. Transocean maintains a larger deepwater floater fleet of over 30 rigs, while Valaris combines a broader jack-up and floater mix. Seadrill's advantage is fleet age — its ultra-deepwater drillships average under 10 years, translating to lower maintenance downtime and higher dayrate premiums when markets tighten. The company deliberately avoided rebuilding a large shallow-water fleet, concentrating capital where barriers to entry are highest.

Seadrill has not diversified into renewables, carbon capture, or offshore wind installation, maintaining a pure-play offshore oil and gas drilling focus. The company's energy transition posture is operational: its modern rigs consume less fuel and produce lower emissions per well drilled than older-generation assets, which helps clients meet scope-one reduction targets. This contrasts with peers like Noble Corporation, which has explored offshore wind vessel partnerships. Investors seeking transition-exposed offshore names would find Seadrill among the least diversified.
