SEADRILL UK LTD.
SEADRILL UK LTD. is a Private limited company (Ltd.) registered in United Kingdom under 06537528, and its current status with Companies House is active. The company was incorporated on 18 March 2008 and lists its registered address as Liverpool, United Kingdom. 1 shareholder is on record for SEADRILL UK LTD., 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 19 October 2026.

Shareholders
1
One shareholder is currently on record for SEADRILL UK LTD., held on the Confirmation Statement (CS01), filed under the Companies Act 2006.
The largest of these is SEADRILL LTD, holding 100% — a majority holding.
Because the shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
Three of the 5 officer records shown for SEADRILL UK LTD. are current appointments, filed with Companies House. William Crombie (appointed 2025-03-31), TRACY THORNTON (appointed 2025-03-31) and James Gilbertson (appointed 2025-08-04) all serve as Director. The remaining 2 records shown (Philip Lindley and Thomas Hoang) are former appointments that have since been resigned.
The register reports 20 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at SEADRILL UK LTD. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
SEADRILL UK LTD. sits 2 levels below its ultimate parent, Seadrill Limited, registered in Bermuda. 3 subsidiaries are recorded beneath it, across 4 jurisdictions. The full chain up to Seadrill Limited is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by SEADRILL UK LTD.'s own shareholder record. 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 3 subsidiaries span United Kingdom, Norway, Netherlands, Switzerland 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. Two of the 3 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
