OCEANEERING INTERNATIONAL SERVICES LIMITED
OCEANEERING INTERNATIONAL SERVICES LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01023217, and its current status with Companies House is active. The company was incorporated on 6 September 1971 and lists its registered address as London, United Kingdom. 1 shareholder is on record for OCEANEERING INTERNATIONAL SERVICES LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies House and was last updated on 22 September 2026.

Group Structure
OCEANEERING INTERNATIONAL SERVICES LIMITED sits 5 levels below its ultimate parent, Oceaneering International Inc, registered in United States. 6 subsidiaries are recorded beneath it, across 3 jurisdictions. Immediately above OCEANEERING INTERNATIONAL SERVICES LIMITED is Oceaneering AS, holding 100% as filed in OCEANEERING INTERNATIONAL SERVICES LIMITED's own shareholder record with Companies House. Oceaneering International Inc sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 6 subsidiaries span United Kingdom, Norway, India jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 6 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
