Pafupi ndi madoko awiri omwe alipo Mongla ndi Chittagong, ndi nthawi yomanga doko lachitatu panyanja: Payra, doko lomangidwa kuchokera pachiyambi kuti liwonjezere doko lofunika kwambiri komanso kulola zombo zazikulu kuyimba pamalopo, kunyalanyaza kufunikira madoko ena monga Singapore ndi Colombo.
Asitikali apanyanja achi Bengali akupanga njira yolowera ku doko latsopanoli kuchokera kumtunda, Jan De Nul njira yolowera kuchokera kunyanja.
"Timaphatikiza gawo lazinthu zophwanyidwa pamtunda kuti tipange ma terminals amtsogolo.Pachifukwa ichi, timasonkhanitsa zombo zisanu ndi zitatu zowotchera, makilomita ambiri amtunda, mapaipi ozama komanso oyandama komanso zombo zing'onozing'ono kuti zithandizire ntchitoyi, "adatero Jan De Nul.
Dera la dokolo ladzazidwa ndi mchenga pomwe ma terminal adzamangidwapo.Derali lili ndi mahekitala 110.
Khomo lolowera ndi la makilomita 75 ndipo limayenda mpaka makilomita 55 panyanja, kutengera komwe kuli, kuzama ndi cutter suction dredgers (CSDs) kapena trailing suction hopper dredgers (TSHDs).
Ma hopper amatayira mchenga kunyanja kapena kuuphatikizira pamtunda pamalo otayira dredge.
Odulira onse amalumikizidwa ndi mzere woyandama wautali wa makilomita 2.5, kudzera momwe zinthu zodulidwira zimasamutsidwira kumalo oyenera kutaya panyanja.
Ma CSD ndi zombo zoyima zoboola.Ikafika pamalo oyenerera, anangula awiri amatsitsidwa, ndipo spud imalowa pansi panyanja kuti ikhale yoyenera.
Panthawi ya ntchito zowononga, wodulayo amayendayenda pansi panyanja kuchokera ku nangula wina kupita ku wina.
Ngati nyengo simalolanso kuti spud ikhale yotsika, ndipo motero dredging sangathe kupitilizidwa, spud imakwezedwa, ndipo nangula wachitatu amatsitsidwa - chotchedwa storm-nangula - kusunga sitimayo pamalo oyenera. .
