List of ships of Serco Marine Services

List of ships of Serco Marine Services is a list of active ships operated by Serco Marine Services in support of His Majesty's Naval Service (incl. Royal Navy, Royal Marines and the Royal Fleet Auxiliary). As of 2025, Marine Services operates more than 90 vessels at six locations in the U.K. at: Portsmouth, Devonport, Falmouth, Clyde and two at Inner Raasay Sound.

Vessels of the Marine Service range in length from 11 m to 93 m and displace from 12 to 3,600 gross tonnes. Serco employs some 600 to 650 mariners and engineers.

The ships Kingdom of Fife and Cameron are provided by Briggs Marine who won a £100M subcontract from Serco Marine Services for the support and maintenance of the Royal Navy's navigational marks (or buoys) and moorings in the United Kingdom and overseas.

In 2022, a £200m contract with Serco was signed extending the arrangement for a further 27 months commencing in December 2022. Under the arrangement, the Ministry of Defence has the option to extend that contract for up to six more months. In 2025, a ten-year contract was signed to continue to deliver services to the mid-2030s. Under an additional and parallel contract Serco is to introduce 24 new vessels into service on behalf of the Naval Service replacing its older vessels. In 2025, Serco signed a contract with Damen Shipyards Group for the delivery of these 24 vessels as part of a renewal of its fleet. The vessels will include: Azimuth Stern Drive (ASD) tugs, Reversed Stern Drive (RSD) tugs, pilot boats, barges and crane barges. The vessels are to be delivered in 2027 and 2028.

As of 2021, principal marine services in the Falkland Islands were provided by the contracted Netherlands Marine Services company Van Wijngaarden, while in Gibraltar, marine services were provided by the vessels of Boluda Towage Europe which bought the previous Resolve Marine Group in February 2024. Resolve had previously acquired T.P. Towage in 2015 and these vessels provide all harbour towage and other support services in and around the Port of Gibraltar.
