Otto Bröhan was a German fishing trawler that was requisitioned by the Kriegsmarine in the Second World War for use as a Vorpostenboot, serving as V 207 Otto Bröhan and V 206 Otto Bröhan. She was scuttled at Caen, Calvados, France in June 1944. She was raised in March 1945 and converted to a survey ship for the French Navy, renamed Ingénieur Hydrographe Nicolas. She served until 1960 and was then scrapped.
Otto Bröhan was 55.65 metres (182 ft 7 in) long, with a beam of 8.44 metres (27 ft 8 in). She had a depth of 4.21 metres (13 ft 10 in) and a draught of 4.90 metres (16 ft 1 in).[1] She was assessed at 510 GRT, 189 NRT, 1050t displacement.[2][3] The ship was powered by a triple expansion steam engine, which had cylinders of 35 centimetres (13+3⁄4 in), 55 centimetres (21+5⁄8 in) and 88 centimetres (34+5⁄8 in) diameter by 66 centimetres (26 in) stroke. The engine was made by H. C. Stülcken Sohn, Hamburg, Germany. It was rated at 135nhp and 540ihp.[2] It drove a single screw propeller via a low pressure turbine, double reduction gearing and a hydraulic coupling,[2] and could propel the ship at 12.5 knots (23.2 km/h).[1]
HistoryEdit
Otto Bröhan was built in 1937 as yard number 723 by H. C. Stülcken Sohn, Hamburg,[1] for Cranzer Fischdampfer AG, Hamburg.[2] She was launched on 28 December.[4] The Code Letters DJVI were allocated,[2] as was the Cranz an der Elbefishing boat registration PC 9.[4][5] The trawler was named after Otto Bröhan, a fishing boat captain from Hamburg.[6] She entered service on 8 March 1938. On 1 April, her registration was moved to Hamburg as HH9.[4][5] She fished off Norway and Iceland.[6]
On 6 October 1939, Otto Bröhan was requisitioned by the Kriegsmarine for use as a vorpostenboot. She was commissioned into 2 Vorpostenflotille as V 207 Otto Bröhan.[7] Her armament consisted of one 88 mm anti-aircraft gun at the bow and one 20 mm cannon aft.[6] She was redesignated V 206 Otto Bröhan on 20 October.[7] She served in the North Sea, and following the Fall of France she was based at Saint-Malo, Ille-et-Vilaine, France and Saint Helier, Jersey, Channel Islands. In 1943, Otto Bröhan was rebuilt and her armament was strengthened. She now carried a single 88 mm anti-aircraft gun and five 20 mm cannon. Gunners were provided with armoured shields for protection.[6]
In March 1945, Otto Bröhan was refloated, given basic repairs at Caen, and laid up in August 1946.[3] She was acquired by the French Navy and, between 1947 and 1948, converted to a hydrographic survey vessel at the naval dockyard at Cherbourg, Manche.[3][12] She was commissioned on 1 January 1949 as Ingénieur Hydrographe Nicolas, with the Pennant Number P 664.[3] Her armament consisted of two 20 mm cannon.[6][13] Her complement was 68 men.[12][13] She was based at Toulon, Var and was used for survey and mapping work of French and North African coasts.[6]Ingénieur Hydrographe Nicolas was withdrawn from service on 18 July 1960.[12] She was sold at Cherbourg that year by the Domaines de l'État, as Q 193, for scrapping.[3][6]
