Abstract

Proyek Cutter Suction Dredger direncanakan memiliki kapasitas 3000 m3/h dengan kedalaman pengerukan maksimal sebesar 14 m serta elevasi discharge 10 m diatas permukaan laut menggunakan floating pipeline system sepanjang 700 m. Untuk memindahkan sedimen hasil pengerukan ke tempat pembuangan digunakan pompa slurry. Dalam proyek ini bertujuan untuk memilih pompa slurry yang sesuai kebutuhan.
Tahapan dalam proyek ini terbagi menjadi dua, yakni: 1) penghitungan karakteristik fluida dan Head efektif instalasi yang dilakukan secara manual dan secara numerik dengan software pipeflow expert., 2) pemilihan pompa dilakukan dengan cara memplot hasil dari perhitungan kapasitas dan juga head efektif instalasi yang telah dilakukan kedalam kurva unjuk kerja pompa yang sudah tertera pada data sheet pompa. Hasil menunjukkan bahwa Fluida slurry memiliki karakteristik, yakni: Densitas (ρ) sebesar 1269 kg/m3, Specific Gravity (SG) sebesar 1,269, dan Viskositas Dinamis (μ) sebesar 0,0016416 kg/ms. Head efektif instalasi (Heff) untuk fluida air secara analitik didapat 93,666 m dan secara numerik menggunakan pipe flow expert didapat 93,800 m sehingga tingkat kesalahannya 0,1431 % berada pada batas yang diijinkan <2%. Sehingga dalam proyek CSD ini, pompa slurry yang digunakan adalah Warman® 10/8 F-AH High Head Slurry Pump dengan kapasitas 1150 – 4000 m3/h, Head 20 – 100m, Kecepatan 600 – 1000 rpm, efisiensi ± 82%, NPSHR < 4,5 m, dan inlet/outlet diameter 254/203 mm.
==============================================================================================================================
The project of Cutter Suction Dredger is designed to have a capacity of 3000 m3/h and a maximum dredging depth of 14 m and a discharge elevation of 10 m above sea level using a 700 m floating pipeline system. To transfer the dredged sediment to the disposal site, a slurry pump is used. In this project the aims is to select the slurry pump according to the needs.
The stages in this project are divided into three: 1) Calculating the fluids characteristics and effective Head of the installation manually and numerically using Pipe Flow Expert software. 2) Pump selection done by plotting the calculation result of the capacity and effective head of the installation which has worked according to pump performance curve listed in pump datasheet.
The results showed the working slurry fluid has a characteristics, specifically: Density (ρ) of 1269 kg/m3, Specific Gravity (SG) of 1,269, and Dynamic Viscosity (μ) of 0,0016416 kg/ms. The Head effective installation (Heff) for working liquid of water analytically is 93,666 m and numerically, using a pipe flow expert it is obtained 93,800 m thus resulted error rate of 0,1431% within the allowable limit <2%. Therefore, in this CSD project, the slurry pump used is Warman® 10/8 F-AH High Head Slurry Pump with a capacity 1150 – 4000 m3/h, Head 20 – 100m, speed 600 – 1000 rpm, efficiency ± 82%, NPSHR < 4,5 m, and inlet/outlet diameter 254/203 mm
