“There are no longer active leaks with 95 percent of the potential oil volume having been removed. Any remaining oil is enclosed in a few internal tanks without leakage and are well protected with multiple barriers of ship construction. Of the 173 total oil tanks, the 159 external tanks have been pumped of all appreciable amount of oil or were found empty.”-Lieutenant Commander Tim Emge, USN officer-in-charge of salvage operations

In October 2018, at Enubuj Island in Kwajalein Atoll, Marshall Islands, the U.S. Mobile Diving Salvage Unit declared the recovery of fuel oil from the nuclear blasted DKM Prince Eugen completed.

Since radiation levels emanating from the nuclear weapons testing victim were deemed safe enough for humans to dive on, the Republic of the Marshall Islands (the official owner of Prince Eugen since 1986) demanded that the 250-thousand gallons of fuel oil onboard be removed.

The DeutcheKriegsMarine (DKM) Prinz Eugen still has an ongoing radical life story.  Fighting alongside Bismarck at the beginning of World War Two, then surviving numerous bomb and torpedo attacks by the British, surviving the war after fighting the Soviet advance upon Germany to be surrendered to the British empire, which then turned it over to the U.S. Navy where it became the USS Prinz Eugen IX-300.

According to the U.S. National Park Service, the guns from Turret A and the fire control tower were removed before the atomic testing, at the Philadelphia Navy Yard in February-March 1946, as a kind of before-after control.

In July 1946, possibly because the USN was having trouble with the Eugen’s boilers, it was decided to drop The Bomb on it. Amazingly Eugen survived not one, but two nuclear bomb blasts (Able Day and Baker Day).

Color USN Navy film from 20AUG1946, by Photographer’s Mate W.J. Gibson, towing the nuclear blasted USS Prinz Eugen to its impending (and not expected) doom by capsizing, from Bikini to Kwajalein (quality of film is not good). You might notice USN personnel walking about the radioactive ship:

However, after being towed back to Enubuj Island, Eugen suddenly capsized and sank, next to Carlson Island.

Since 1979 various parts have been salvaged by various organizations.

In 2010, Republic of the Marshall Islands wanted the fuel oil still onboard removed for environmental reasons.  The fuel oil recovery began in February 2018 and ended in October 2018.
