The Ol-class tankers were Royal Fleet Auxiliary Replenishment oilers built from 1917-1919 tasked with providing fuel and other supplies to Royal Navy vessels around the world. There were six ships in the class. Until 1936 they were managed by Davies and Newman with RFA crews, after which time they were transferred to the Admiralty.

The lead ship of the class RFA Olcades was originally built as British Beacon and acquired for RFA use in 1918. She was renamed in 1936.

The six ships in the Ol-class saw wide service during World War II as far afield as India, Singapore and the Far East.

The Wave class was a class of replenishment oilers built for service supporting the Royal Navy during the later years of the Second World War.

There were originally ten ships planned in the class, although the final two were cancelled in 1952. Originally designed to act as fleet attendant oilers, in this role the ships were obsolete almost as soon as they were built due to the increasing prevalence of replenishment at sea, and their role was refocused to coastal transport duties.

The two classes are very similar, but are not directly comparable due to large variance in capabilities delivered.
