In brief
Serco Marine Services is a Private Finance Initiative contract, with Serco Group, to deliver auxiliary services to His Majesty's Naval Service (incl. Royal Navy, Royal Marines and Royal Fleet Auxiliary).
Marine Services primarily operates from the nation's three main naval bases, HMNB Portsmouth, HMNB Devonport and HMNB Clyde, but also supports training and operations overseas, as well as at various British Overseas Territories.
Serco Denholm (a joint venture between Serco Group and Denholm Group)
won the Marine Services contract, replacing the subsequently disbanded Royal Maritime Auxiliary Service. Denholm's participation was bought out in late 2009 by its larger partner, Serco. In 2025, Serco won a renewal of the contract to continue services for the Naval Service until 2035.

Ships in registry counts individual vessel records attributed to the company here. Reported fleet is the company’s published total. They measure different things and are shown separately on purpose.
In context
Counts over companies and vessels actually held in this directory — not over the world fleet, which is larger. Nothing here is estimated.
With 5 vessels attributed to it here, Serco Marine Services is the 174th largest of the 965 operators in this directory that hold at least one ship on record, against a median of 2 across that group. That is a count of individually identified hulls, not the company’s published fleet size — the two are different measurements and both are shown above where available.
United Kingdom is the country of registration for 97 commercial operators in this directory, among which Serco Marine Services ranks 11th by ships on record. Between them those companies hold 260 vessels here. See every operator registered in United Kingdom.
