| Source measurement | — | Chauvenet was the first Navy vessel specifically designed and built to conduct coastal hydrographic surveys. With sister ship Harkness the two were to replace the World War II transports converted to coastal survey ships Tanner (AGS-15) and Maury (AGS-16) . The ship was operated by MSC with a civilian crew under the technical direction of the Oceanographer of the Navy through the U.S. Naval Oceanographic Office (NAVOCEANO). The surveys were conducted by a complement of military and civilian surveyors. The ship embarked four 36 ft (11.0 m) launches, two helicopters, chart production and printing equipment, the Navy/civilian survey detachment and a Navy Sea Bee coastal survey team with landing and shore vehicles. Survey operations, under NAVOCEANO's Hydrographic Surveys Department, were conducted by the United States Navy's (USN) Oceanographic Survey Unit 4 (OCUNIT4). United States Navy units aboard consisted of a helicopter detachment, a detachment of Seabees as well as several other Navy departments supporting survey missions.[source]USNS Chauvenet · Navy coastal surveys; only the objects and conditions stated in this passage The ship, primarily assigned to the Pacific, was equipped with an early shipboard data acquisition and processing system designated the Hydrographic Data Acquisition System (HYDAS) based on the PDP-9 computer. The identical system was installed aboard Harkness . Similar systems were installed on Sgt. George D Keathley (T-AGS-35) and Kellar (T-AGS-25) . One computer was dedicated to real time collection of survey data and another to processing the data for making nautical charts or being a backup for the real time data collection in event of failure of that computer. A real time navigation plot was generated on a flatbed plotter. The processing computer processed data collected by the ship and the sounding launches which had an associated data collection system designated HYSURCH for hydrographic survey and charting system. The launches themselves were 36 foot fiber glass, diesel powered, "sports sedans" capable of 30 kn (35 mph; 56 km/h) smooth water speed and modified for survey operation.[source]USNS Chauvenet · Navy coastal surveys; only the objects and conditions stated in this passage Chauvenet grounded two hours before midnight 8 May 1982 on Dauisan Reef ( 09°47′0″N 121°13′30″W / 9.78333°N 121.22500°W / 9.78333; -121.22500 ) in the Sulu Sea while transiting from Subic Bay to survey areas in Indonesia. Damage was considerable with flooding of several spaces. Navy salvage operations based aboard Brunswick (ATS-3) over two weeks refloated the ship for temporary repairs at the Ship Repair Facility at Subic before being towed to Sasebo , Japan for permanent repairs.[source]USNS Chauvenet · Navy coastal surveys; only the objects and conditions stated in this passage |
