The Royal Maritime Auxiliary Service (RMAS) was a British Government agency which ran a variety of auxiliary vessels for His Majesty's Naval Service (incl. Royal Navy, Royal Marines and Royal Fleet Auxiliary). The service from 2009 has been run by Serco and is known as Serco Marine Services.

Background

The Royal Maritime Auxiliary Service merged with the former Port Auxiliary Service in 1976 to form a component of His Majesty's Naval Service that was known as marine services. Marine services existed to support the operations of the Royal Navy, Royal Marines and Royal Fleet Auxiliary.

In the 1990s, marine services were put out to commercial tender by the Ministry of Defence Warship Support Agency (now absorbed into the Defence Equipment and Support organisation) and by 1996, all tugs, lifting craft, various tenders and management of HMNB Devonport, Portsmouth and Clyde were operated by Serco Denholm.[http://www.serco.com/media/pressreleases/2002/014_2002.asp Marine Services Planning Agreement] {{webarchive |url=https://web.archive.org/web/20060428001206/http://www.serco.com/media/pressreleases/2002/014_2002.asp |date=28 April 2006 }}

By the mid 2000s, it was decided that the Royal Maritime Auxiliary Service would no longer provide marine services to HM Naval Service, and it would instead be delivered under a Private Finance Initiative instead. Serco were quickly declared preferred bidders and the RMAS was disbanded on 31 March 2008.{{cite web |url=http://www.serco.com/media/pressreleases/2006/marineservices.asp |title=£1 billion MoD Marine Services contract |publisher=Serco.com |access-date=2011-12-06 |url-status=dead |archive-url=https://web.archive.org/web/20120204193635/http://www.serco.com/media/pressreleases/2006/marineservices.asp |archive-date=4 February 2012 |df=dmy-all }}[http://www.royalnavy.mod.uk/server/show/ConWebDoc.12268/changeNav/6568 Queen’s Thanks as Last Post Sounds for Royal Maritime Auxiliary Service]

Vessels

RMAS vessels carried the ship prefix "RMAS" and auxiliary (A) or yard (Y) pennant numbers. They also had a distinctive livery or colour-scheme, namely: black hulls with white beading and buff-coloured upperworks. Below is a list of vessels previously operated by the Royal Maritime Auxiliary Service. A number of the vessels listed below were later transferred over to Serco Marine Services who continue to provide marine services in support of the Royal Navy.
