Examination of the underwater portions and the bottom-level regions of hydraulic structures by divers is very important in submarine engineering. This article discusses such examination as carried out by divers equipped with aqualungs and suggests that because of the huge frontage in ports, wharves, docks, etc., the completely new method of television examination of underwater structures has indisputable advantages: reliability of the information, practicality, and ready display of information to specialists for group decision. The Central Scientific-Research Institute for Transport Construction of the Ministry of Transport Construction has developed a mobile television unit for inspecting port installations. Five units are in current use. First indications are that they are 2.5 to 3 times more efficient than divers in ventilated equipment. Attachments to the television units make it possible to examine almost vertical underwater structures, but divers cannot as yet be completely replaced. Underwater photography already enjoys preference among specialists, although in many instances the murkiness of the water makes it necessary to use attachable bells to replace the dirty with clean water and permit photography. A Leningrad plant for experimental underwater photographic equipment in 1967 put out such bell attachments. The author cites inspection by aqualung divers in Tallin, Riga, Murmansk, Nakhodka, Vladivostok, and Sheskharis and instances the 140 shifts needed by 40 divers to inspect 8000 sq. meter of fill wharves and 620 running meters of piling.
