The ship was built in 1935 at the Kremer Werft in Elmshorn for the distribution point for chlorinated lime and the ship management by the Lübeck shipping company Lübeck-Wyburger Dampfschiffahrtsgesellschaft. The Norden resembled a conventional coaster with aft superstructures and engine room. In the hold , however, it had four 45 m³ cylindrical gas tanks made of seamlessly drawn Mannesmann pipe for a working pressure of up to 10.5 bar. The ship was powered by a six-cylinder four-stroke diesel engine made by MWM with 150 hp, the on-board power delivered two auxiliary diesels with 15 hp each. After the positive experience with the Norden , the shipping company also had the comparably designed but slightly larger ship Trave built near Kremer in 1939 . In 1940 the Navy commandeered the ship. It stayed in motion until 1945 on behalf of IG Farbenindustrie . The cargo handling in Lübeck took place at a shore station of IG Farben, where the chlorine was pumped into the ship by means of a compressor from tank wagons . The transports initially carried chlorine to Norway, but during the war, chlorine from Mäntyluoto in Finland was loaded from barrels using a mobile system and unloaded in Königsberg . Both ships survived the Second World War and were transferred by their crews to Methil after the war and delivered there to the shipping controller .
Great Britain passed the north on to Norway in 1946, where it operated under the management of A / S Nordag and the name Bergsnes from 1946 , before it was passed on to the Herøya Elektrokjemiske Fabrikker in Porsgrunn in 1947, who operated the tanker as Klor . In 1953 the ship was transferred to Hydro Tankskips A / S without being renamed. In 1959 Martin Sætre from Mastrevik / Bergen became the new owner. He renamed it Sætre and had the ship extended and converted into a dry freighter, which increased the carrying capacity to 350 tons. In 1965 the ship received a new Wichman three-cylinder two-stroke diesel engine with 30 hp. In 1967 Harald Sætre from Eidsvågsneset / Bergen took over the ship and from 1971 it was sailing as Aro for Jonas Austnes in Haramsøy / Ålesund. In October 1973 Sigurd Botn from Austefjord / Ålesund acquired the Aro , but sold it in 1976 to Magnar Brandal from Brandal / Ålesund. On May 11, 1978 the Aro leapt on a trip from Austefjord to Raudeberg with sand in front of Måløy and sank, killing one crew member.
The Trave
After being handed over to the shipping controller , the Trave, which was built in 1939, was initially in operation until 1952, before it was put back into service by the Hunting & Sons shipping company as Empire Chlorine until 1953 . In 1954 the ship was renamed to the old name Trave for a short time , then in Hybo and then in Hyborg , before it was put into service in the same year for the Norwegian shipping company A / S Klorsalg under the name Uniklor . From 1978 the ship with the IMO number 5373139 sailed as Frisnes for the shipping company Frimann Skeie from Kopervik. In 1989, the ship moved within Norway to the Oystein Forge shipping company, which operated it as Hinnatank until 2000 . Since then, the ship, which has meanwhile been equipped with an alpha diesel main engine with an output of 257 kW, has been operating as Miljøtank for the Norwegian shipping company Miljøtank A / S until 2005 and for the shipping company Mongstad Sjøtransport A / S from Fonnes since 2005.
