Ⅰ. Imbali yoPhuhliso lweImpompo yokuNciphisa eLwandle
1. Iimpompo ze-PN zokutsalwa kwechungechunge zaveliswa ngaphambi kwee-1980s, ezinobungakanani ukusuka kwi-1PN ukuya kwi-10PN,
2. Emva kweminyaka yoo-1980,iimpompo ezinodakaukusuka phesheya kwaqaliswa: siphucule uthotho lwe-G (GH), olusetyenziswa kwi-cutter suction dredger ukumpompa amasuntswana amakhulu egrabile; Uchungechunge lwe-AH lweempompo luphuculwe kwimpompo yokukhupha i-sludge discharge; Iimpompo zodaka ezintywilayo zisetyenziselwa ukudiliza kumazibuko kunye ne-submarine trenching kunye nokubeka intambo.
3. Emva kwe-2000, iimveliso ezine, i-250WN, i-300WN, i-450WN kunye ne-500WN, ziye zavavanywa kakuhle kwi-"Hundred Ships Plan" yaseChina.
4. Emva kowama-2005, ukusetyenziswa okuyimpumelelo kweemodeli ezinkulu zeempompo ze-dredge kunye neempompo zoxinzelelo oluphezulu zokugungxula ezinobubanzi obungaphezulu kwe-600 kunyuse uyilo kunye nokuveliswa kweempompo ze-dredge kwinqanaba elitsha.
