SUBSEA 7 DEEP SEA LIMITED
SUBSEA 7 DEEP SEA LIMITED is a Private limited company (Ltd.) registered in United Kingdom under SC257774, and its current status with Companies House is active. The company was incorporated on 17 October 2003 and lists its registered address as WESTHILL, United Kingdom. 1 shareholder is on record for SUBSEA 7 DEEP SEA 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.

Those 1 subsidiary spans United Kingdom, Norway 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. One of the 1 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
