The sailors joined the Lothringen in Rotterdam. The guns were mounted and the ship was fueled. On the 7 March 1941 the ship sailed for the port of Cherbourg, France, arriving in the afternoon of 8 March. Lothringen then visited Brest harbour, then Saint-Nazaire on 20 March followed by La Pallice on 11 May. Outfitting and supplies

 Fuel oil for surface craft, received from the tanker Rheum that taken together amounted to 11,000 ton. Provisions and fresh water. metal drums of lubricating oil for U-boats. Capture
On 11 May 1941, Lothringen started in [a Pallice, the deep-water port of La Rochelle, France. The ship was due to rendezvous with a U-boat on 17 June 1941, however on the early morning of the 15 June Lothringen was sighted at position 
, north west of the Cape Verde Islands, by Fairey Swordfish aircraft of the aircraft carrier HMS Eagle while on patrol as part of  Operation Salvage looking for commerce raider and  U-boat supply ships in the South Atlantic. The Swordfish attacked with machine-gun fire and 250lb bombs damaging the ships lifeboats. The lack of seaworthy boats meant that the crew never scuttled the ship and Naval Intelligence at the time described it as the first time a ship surrendered to aircraft. The ship was captured on the same day at 17:00 by the  light cruiser . When the Lothringen was captured, it provided valuable new techniques and design in Replenishment at sea and specifically a new type of buoyant rubber hose. Allied service

In September, it left Bermuda, crewed by the Royal Fleet Auxiliary and sailed to Halifax, Nova Scotia, Canada and in October sailed from there to the United Kingdom as part of Convoy HX 153. Empire Salvage was used in refuelling experiments with other British ships before fitting out with armament. Empire Salvage returned to Halifax and served there as "Station Oiler". For Operation Husky, Empire Salvage was in the Mediterranean refuelling ships in Algiers harbour and the Gulf of Salerno. In late 1944, Empire Salvage transferred to the Far East supporting British operations there around Ceylon. The Empire Salvage was transferred back to the Dutch government but chartered by the Ministry of War Transport for continued operations. Post war
