"During the weekend of March 29-30, operation will commence at sea to transfer the remaining 202,485 barrels of Jet-A1 cargo from the Stena Immaculate tanker to tanker Fure Vyl, which is anchored nearby," Crowley said.

The Portuguese-flagged Solong ran into the US-flagged Stena Immaculate about 20 kilometres (13 miles) from the northeastern English port of Hull on March 10, triggering huge fires aboard the two ships.

The Solong was towed on Friday to the port city of Aberdeen on the east coast of Scotland.

The vessel had been moved away from the crash area and was "now safely berthed at the Port of Aberdeen, where further salvage operations will be undertaken", Chief Coastguard Paddy O'Callaghan said.

The Coastguard would continue to support local authorities tackling pollution along the east coast of England "including plastic nurdles", O'Callaghan added.

The nurdles came from the Solong, which was transporting a number of containers filled with the plastic pellets, the ship's German owner, Ernst Russ, has said.

Nurdles are 1.0- to 5.0-millimetre (0.04- to 0.2-inch) pellets of plastic resin used in plastics production.

They are not toxic but can damage wildlife if ingested.

One crew member from the Solong, identified by state prosecutors as 38-year-old Filipino Mark Angelo Pernia, is presumed dead.

The Solong's Russian captain has been charged over with gross negligence manslaughter.

At the time of the crash, the US military-chartered Stena Immaculate, which was at anchor, was carrying around 220,000 barrels of aviation fuel, at least one of which ruptured.

An initial review by Crowley suggested the amount of fuel released was "limited" due to evaporation and exposure to fire.

No cause for the crash has yet been established.
