Besides periodically inspecting the structures in tile domes and recommending improvements in their design, materials, and maintenance, APLUW has recently developed an instrument package to monitor selected parameters of the dome water in situ. Previously, analyses of dome-water corrosivity combined information from three sources: water samples collected as the dome was pumped out, pierside measurements, and laboratory tests of the electrochemical corrosion rate of typical materials used in the dome. With this procedure, dome water samples were obtained only at the end points of the operation cycle, i.e., during maintenance prior to and following patrol. The new instrument package (called the Dome Water Monitoring Instrumentation System, or DWMIS) monitors and records dame-water parameters such as salinity, conductivity, pH, temperature, dissolved oxygen, and galvanic potential periodically each day to establish changes and trends. The goals of this monitoring program are to understand dome water corrosivity and how the corrosivity is affected by the exchange rates between the dome and surrounding, external seawater. The knowledge gained will be used to formulate recommendations for reducing the corrosivity of the dome water.<<ETX>>","PeriodicalId":130255,"journal":{"name":"Proceedings of OCEANS '93","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127128235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control system allows the user accurately control cable bottom slack and position the cable along a pre-planned route. The system was successfully used to lay an underwater acoustic tracking range for the US Navy. A total of eight, 40 mile long cables, each having eight in-line hydrophones and several repeaters were laid in water depths of 40 m to 1800 m off San Clemente Island, California. The hydrophones were placed within specific targets along the cable route despite multiple abrupt turns in the paths, and a fully functional acoustic range is now in place. The flexibility and accuracy of the system in controlling cable bottom slack and cable bottom placement are presented using data from this Navy cable lay. The importance of properly measuring drag coefficient and forecasting currents for deep ocean cable lays is also discussed. The cable deployment control system proved that it can provide proper ship and cable engine commands to recover from unexpected full ship stops and resume deployment operations with no adverse effects on the cable lay.<<ETX>>","PeriodicalId":130255,"journal":{"name":"Proceedings of OCEANS '93","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126829387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
