In 1980, she was sold to the Royal Aircraft Establishment, Farnborough and renamed Colonel Templer after Colonel James Templer, an early British military pioneer of balloons and superintendent of the Aldershot balloon factory.

After a serious fire in 1990, the ship underwent a major rebuild and in November 2000, Colonel Templer was handed over to the Royal Maritime Auxiliary Service (RMAS) and operated under contract by Serco Denholm, based at HMNB Clyde.

Following the disbandment of the RMAS in March 2008, Colonel Templer was transferred to Serco Marine Services and received the ship prefix 'SD'.

In July 2011, she was sold to a Swedish firm and renamed Seaway Endeavour with a blue and white livery.
