Looks like she was acquired 7/2012 by Queensway navigation for service as a storage vessel at Gibraltar for the Macoil/Vemaoil bunkering operation, and she was there most of the time until her sale in 11/2014. There were a few gaps in her recorded presence at Gibraltar during those 2+ years (one was probably a drydocking/repairs in Greece, and shorter ones probably for picking up new fuel stock at a N African refinery).
In most Gib photos during that time she has either a Vema bunkering tanker alongside, or at least Yokohama fenders deployed.

In 11/2014 she was sold to Pavino Shipping, who run a bunkering business, primarily in Russian Far East ports - as well as crude transport from Middle East to Far East.

Any ideas what this ship was doing in Gibralatar for such a long time?
