Isosiyete y’Abanyamerika TDI-Brooks yarangije ubukangurambaga bukomeye bw’ubushakashatsi ku nkengero z’inyanja ya New York na New Jersey. Hagati ya Mutarama 2023 na Gashyantare 2024, iyi sosiyete yakoze gahunda nini yo gusesengura aho umuyaga uturuka mu nyanja mu mazi abiri yo mu ntara n’ay’igihugu.
TDI-Brooks yakoze imirimo itandukanye nko gusesengura imiterere y’ubutaka, gusesengura ibintu birambuye bya UHRS, gusesengura imiterere y’ibyataburuwe mu matongo, gupima imiterere y’ubutaka n’ingero z’amazi yo mu nyanja mu byiciro bitandukanye.
Iyi mishinga irimo ubushakashatsi ku burebure bwa kilometero zisaga 20.000 z’ubukode bw’imitingito bw’imiyoboro imwe n’iy’imiyoboro myinshi hamwe n’imiyoboro y’insinga ku nkombe za New York na New Jersey.
Intego, ishingiye ku makuru yakusanyijwe, ni ugusuzuma imiterere y’inyanja n’inyanja, bishobora kuba birimo ingaruka zishobora kubaho (ingaruka za geologiya cyangwa ibyago byatewe n’abantu) zishobora kugira ingaruka ku ishyirwaho ry’imashini z’umuyaga n’insinga zo munsi y’inyanja mu gihe kizaza.
TDI-Brooks yakoreshaga ubwato butatu bw’ubushakashatsi, ari bwo R/V BROOKS McCALL, R/V MISS EMMA McCALL na M/V MARCELLE BORDELON.
Iperereza rya tekiniki ryakozwe ryakozwe ku bikoresho 150 bya Pneumatic Vibratory Cores (PVC) n'ibindi bikoresho birenga 150 bya Neptune 5K Cone Penetration Tests (CPTs) byakusanyijwe mu gace k'ubukode n'inzira y'insinga ya Offshore Cable Track (OCR).
Hamwe n'iperereza ryakozwe ku nzira nyinshi zo gusohokeramo, hakozwe ubushakashatsi bw'ubutasi buzenguruka agace kose kakodeshejwe, imirongo y'ubushakashatsi ishyirwa ku ntera ya metero 150, hanyuma hagakurikiraho ubushakashatsi burambuye bw'ibyataburuwe mu matongo ku ntera ya metero 30.
Ibyuma bipima ikirere byakoreshejwe birimo Dual Beam Multibeam Sonar, Side Scan Sonar, Seafloor Profiler, UHRS Seismic, Single Channel Seismic Instrument na Transverse Gradiometer (TVG).
Ubushakashatsi bwakorewe ku bice bibiri by'ingenzi. Agace ka mbere karimo gupima impinduka mu burebure bw'amazi n'imisozi, kwiga imiterere yayo (imiterere n'imiterere y'imiterere y'inyanja bitewe n'imiterere y'ubutaka), kugaragaza ibintu byose bibangamira ibidukikije cyangwa byakozwe n'abantu ku butaka bw'inyanja cyangwa munsi yayo nk'amabuye, imiyoboro, ibihombo, ibintu birimo amazi y'umwuka, imyanda (isanzwe cyangwa ikozwe n'abantu), imyanda, inyubako z'inganda, insinga, nibindi.
Icya kabiri ni ugusuzuma ingaruka mbi zishobora guterwa n’amazi maremare zishobora kugira ingaruka kuri utwo duce, ndetse n’iperereza ryimbitse rya tekiniki y’isi mu gihe kizaza muri metero 100 uvuye hasi mu nyanja.
TDI-Brooks yavuze ko gukusanya amakuru bigira uruhare runini mu kugena ahantu heza ho gukorera imishinga yo mu nyanja nko mu mirima y’umuyaga.
Muri Gashyantare 2023, isosiyete yatangaje ko yatsindiye isoko ry’ubushakashatsi ku birebana n’imiterere y’ubutaka, imiterere y’ubutaka n’ingero z’amazi yo mu nyanja kugira ngo yige imiterere y’amazi yo mu nyanja mu gace k’ubukode bw’umushinga ndetse n’inzira zishobora koherezwa mu mahanga ziturutse ku nkombe y’uburasirazuba bwa Amerika.
Mu yandi makuru aturuka kuri TDI-Brooks, ubwato bushya bw’ubushakashatsi bw’iyi kompanyi, RV Nautilus, bwageze ku nkombe y’uburasirazuba bwa Amerika muri Werurwe nyuma yo kuvugururwa. Ubwo bwato buzakorerayo ibikorwa by’umuyaga wo mu mazi.
Damen Shipyards ikorana n'abakora mu nganda z'ingufu zo mu mazi hirya no hino ku isi. Ubumenyi n'uburambe byabonetse binyuze mu bufatanye bwa hafi n'ubufatanye bw'igihe kirekire byatumye habaho itsinda rikomeye ry'amato mato n'amanini ahuye n'ubuzima bwose bwo mu mazi hibandwa ku ngufu zishobora kuvugururwa. Igishushanyo mbonera gisanzwe gifite ibice bya modular gitanga [...]
