Ministry of Earth Sciences, Annual Report 2007-08In order to study effects of sediment re-suspension and resettlement, monitoring of the environmentalparameters have been carried out during 10th plan by collection of samples at the test and referenceareas for the benthic disturbance experiment periodically. Results of the monitoring cruises haveindicated that some of the sediment characteristics appear to have regained the conditions similarto that of pre-disturbance stage, the numbers and diversity of benthic organisms showed onlymarginal restoration. The parameters indicate that the benthic conditions are steadily moving towardsrestoration and the effect of disturbance is waning off.Regarding environmental variability data in Central Indian Ocean Basin (CIOB), the results of onedegree spacing sampling showed distinct difference in distribution patterns of sedimentcharacteristics, faunal assemblages and seafloor morphology which are critical for mining activity.More data was collected in the likely first generation mine site for knowing the spatial variation indistribution patterns and the data are being processed. This work was entrusted to National Instituteof Oceanography (NIO), Goa.3.3 Technology Development (Mining):The National Institute of Ocean Technology has been actively involved in the development oftechnology for Polymetallic nodule mining from 6000m water depth. The various components ofthe project are:3.3.1 Development of underwater mining system for long term operation:The mining trials were conducted using Research Vessel ORV Sagar Kanya and the underwatercrawler was successfully tested during year 2000 off Tuticorin coast at 410 m depth for shortperiod.In order to qualify the LARS, a dummy weight of approximate size 3mx3mx3m was manufactured.The systems were initially qualified using a crawlerdummy weight at a depth of 357 meters off Chennaicoast.After completion of dummy trials and satisfactoryperformance of LARS and DP system, crawlertrials were carried out near Angria Bank offGoa coast. The launching operation went intwo phases. In the first phase, it was launchedto a depth of 20m and all the operationsincluding slurry pumping was done at45 m 3 /h.Crawler dummy weight launched throughLARS from ORV Sagar Kanya18
Deep sea testing of underwater mining systemfor long term operation at a depth of 515 m offChennai Coast with new isolated oil filled pressurecompensated sub-sea power pack wascompleted off Chennai Coast during mid July2006 to study the behavior of various subsystemswith the new configuration, without the crawlersitting on sea floor.3.3.2 Development of underwater collectionand crushing system for Manganese NoduleMining.Underwater crawler entering the splashzone in seaThe second phase of development is the development of collection and crushing systems formanganese nodule mining. The system is being designed for mining rate of 8 tons/hour of wetnodules with nodule abundance of 5 to10 kg/m 3 in sea floor. The manipulator in sand miningcrawler will be removed and replaced with collector & crusher. The Crawler will be made tocollect artificially laid nodules at 500m depth for qualifying system. The two phases of theproject are:a) Development of Artificial Nodule Laying System.b) Underwater Collection and Crushing System for Manganese Nodule Mining.A Remotely Operated Subsea Artificial Nodule Laying System has been developed for creatinga small mine site similar to that of the one in CIOB. Artificial nodules have been prepared withproperties close to that of manganese nodules. The system was tested successfully off Chennaicoast at a depth of 518 m during the third week of June, 2007.3.3.3 Development of soil tester forin-situ measurement of soil propertiesin the Central Indian Ocean Basin.Subsea Artificial Nodule Laying Systembeing launchedIn-situ soil strength values are very usefulinputs for design of underwater crawler formining nodules from soft sea floor. An Insitusoil tester capable of operation in 6000mdepth has been developed jointly withSEVMORGEO, Russia to measure the insitusoil properties in Central Indian OceanBasin.19
