The tuubada nuugista ayaa inta badan lagu dabaqayaa gacanta jiidista ee '' '' 'Fredetger' (TSHD) ama jaranjarada cutter-ka ee dredger cabirkiisu (CSD). Marka la barbardhigo tuubooyinka dheecaanka, tuubooyinka nuugista waxay u adkeysan kartaa cadaadiska taban marka lagu daro cadaadis wanaagsan, oo si isdaba joog ah uga shaqeyn kara xaaladaha foosha xun. Iyagu waa tuunbooyinka caagga ah ee caanka ah ee loogu talagalay drengers.

Tilmaamaha ugu muhiimsan ee tuubooyinka nuugista ayaa ah caabbinta wanaagsan, iska caabbinta cimilada, iyo dabacsanaanta.

Caadi ahaan cadaadiska ugu sarreeya ee shaqada ee tuubooyinka nuugista ayaa ah ilaa -0.1 MPA, iyo cadaadiska tijaabada waa -0.08 MPA. Hogaagga nuugista leh shuruudaha gaarka ah ama loo habeeyay, sida kuwa u adkeysan kara cadaadiska u dhexeeya -0.1 MPA ilaa 0.5 MPA, ayaa sidoo kale la heli karaa. Tiirarka nuugista ayaa ku habboon heerkulka himilada ee u dhexeeya -20 illaa 50 ℃ ℃, oo ku habboon in la gudbiyo isku-darka biyaha (ama bacda, dhoobada, dhoobada, dhoobada, dhoobada) 1.0 g / cm³ ilaa 2.0 g / cm³.

Tiirarka caloosha ee CDSR waxay u hoggaansamaan shuruudaha Heerarka Caalamiga ah ee Iso28017-2018 iyo heerka warshadaha kiimikada Wasaaradda Shiinaha Hg / T2490-2011, waxayna sidoo kale la kulmi karaan shuruudaha waxqabadka sare iyo waxtarka ee macaamiisha.

Marka loo eego xaalado shaqo oo kala duwan, guud ahaan waxaa jira afar nooc oo ah tuubooyinka nuugista: Tuubbada nuugista oo leh naasos bir ah, tuubada nuugista, tuubada nuugista, tuubada rasaasta xinjirta leh iyo tuubada tuubada xirta.
