CS Pacific was a cable ship registered in Copenhagen, Denmark owned by the Great Northern Telegraph Company. The steel vessel was built in 1903 in the shipyards of Burmeister & Wain and delivered that year for the purpose of laying and repairing submarine cable in the Far East networks. Historical records of this cable ship are kept in the National Maritime Museum of Denmark. Pictorial records of the ship are available through the DieselHouse interactive initiative. Operations The vessel was based in Shanghai where the Great Northern Telegraph China and Japan Extension Company had its central office in the Telegraph Building located in the Bund. In addition to the CS Pacific another cable ship called Store Nordiske was assisting in the general maintenance and repairs of the Chinese and Japanese links concerned mainly with the sections Vladivostok-Nagasaki, Nagasaki-Shanghai, Shanghai-Hong Kong involving more than 2000 nautical miles of submarine cable. The classification society Bureau Veritas was in charge of the regular survey of the ship. In the 1910s the CS Pacific underwent a major refit in the Shanghai Old Dock in order to get a long awning over the main deck and new rigging to support the wireless antennas. The decks and upper bridge were regularly covered by large canvas to mitigate the effects of the hot temperatures and heavy rains of the humid subtropical climate. In 1932, Axel Ejner Christiansen, the Captain of the sister ship Store Nordiske died of cholera. Two minor incidents are recorded in the history of the vessel. Some damage occurred in 1904 during the journey from Copenhagen to Shanghai due to heavy storms. In 1939 a collision between the CS Pacific and Italian steamer Granatiere Padula is also recorded. The accident happened in the Huangpu River and caused little damage. Cable gear To carry out her main duties, the ship was equipped with different machinery and cable gear supplied by the electrical company Johnson and Phillips (Charlton, Kent, UK) The manufacture of this heavy metal equipment took place in 1902 by the Telegraph Engineers Department of J&P. Cable engines were mounted one forward and one aft of the machine. Cable drums to pick up and pay out the cable were installed in the spar deck where a dynamometer was also installed. The ship was equipped with three cable tanks with a cone in the middle used as a water tank. The diameters of these tanks
