RFA Oakleaf (A111)

The RFA "Oakleaf" (A111) is a Leaf-class fleet support tanker of the Royal Fleet Auxiliary.Formerly the Swedish vessel MV "Oktania" built by A. B. Uddevalla, Sweden and completed in 1981, Oakleaf was added to the Royal Fleet Auxiliary in 1986.

As well as their role of replenishing warships at sea, support tankers perform the bulk movement of fuels between MOD(N) depots. The Oakleaf has three Leaf Class sisters - RFAs "Brambleleaf", "Bayleaf" and "Orangeleaf". All four were originally designed as commercial tankers and underwent major conversions to bring them up to RFA standards and equip them for naval support. These involved adding a considerable amount of electronics, both in communications and navigational aids, fitting two replenishment rigs and increasing the amount of accommodation.

While the ships can provide some food and stores support, their main cargoes are diesel and aviation fuel. The Oakleaf is capable of replenishing ships with fuel using a standard jackstay or derrick rig abeam and towed rig for astern replenishment. She is fitted to take containers on her main deck for the provision of stores and to enhance ship's stores capabilities for long deployments.

The normal complement is 36, in her current deployment is 15 officers and 22 senior and junior ratings. Among the departments, the PO (Supply) is responsible for 5,000 stores line items as well as for victualling, clothing and bedding . The RISC (RFA Interim Stores Computer) system is his only assistant on board. This system is to be replaced by Oasis 4 in due course.

RFA Oakleaf is powered by a four cylinder Burmeister and Wain long stroke oil engine capable of developing 12,000 bhp driving a single controllable pitch propeller. She also has bow and stern variable pitch thrust propellers. Fitted with automatic power management, the vessel can be operated with her machinery spaces unmanned - as with her sister ships, her engines can be controlled from either the ship's bridge or the (air conditioned) machinery control room.

Following a refit last December and BOST in Januarywhen , she recommenced her duties in the Caribbean as tanker to the West Indies Guard Ship.Clarifyme|date=March 2008
