analisa stabilitas ponton 8.4m
DESCRIPTION
analisa stabilitas ponton yang bertujuan untuk mengetahui batas aman olah gerak excavator.TRANSCRIPT
1
PERHITUNGAN STABILITAS ( FINAL STABILITY )
NAMA PONTON : PONTON 8.4m
TYPE : PONTON CATAMARAN
PEMILIK : -
I. Ukuran Utama Ponton :
Panjang seluruhnya (Loa) = 8.4 m
Panjang garis tegak (Lpp) = 8.4 m
Lebar (B) = 6.2 m
Tinggi (H) = 1.4 m
II. Penilaian Stabilitas
Penilaian stabilitas didasarkan pada tabel analisa stabilitas dengan berbagai kondisi
simulasi operasi.
III. Berat dan Tititk berat kapal kosong
Berat dan titik berat kapal kosong dibagi menjadi dua bagian, yaitu :
1. Berat konstruksi
2. Berat excavator dan beban yang diangkat excavator.
Perhitungan berat dan titik berat pada tiap-tiap bagian konstruksi dihitung berdasarkan
estimasi berat konstruksi, berat excavator dihitung dari data spesifikasi dari maker,
perlengkapan dihitung berdasarkan perkiraan.
Untuk perhitungan tersebut didasarkan pada gambar dan dokumen pendukung antara
lain sebagai berikut :
1. Rencana Umum
2. Rencana konstruksi
3. Data spesifikasi excavator.
Dengan hasil sebagai berikut :
Berat kapal kosong = 11 ton (approx.)
Titik berat terhadap garis tegak buritan ( AP-G ) = 4.2 ton (approx.)
Titik berat terhadap dasar ( KG ) = 0.75 m (approx.)
2
IV. Rencana Tangki-tangki dan Perlengkapan
Rencana tangki-tangki dan perlengkapan untuk perhitungan stabilitas ini dapat dilihat
pada gambar rencana umum.
V. Perhitungan stabilitas
Perhitungan stabilitas yang dilakukan dengan berbagai simulasi kondisi operasi
ponton, adalah sebagai berikut :
1. Kondisi ponton kosong dengan excavator diatasnya, tanpa beban kerja excavator.
2. Kondisi ponton kosong dengan excavator diatasnya, dan excavator bekerja pada
maksimum reach at ground level.
3. Kondisi ponton kosong dengan excavator diatasnya, dan excavator bekerja pada
maksimum loadingheight.
4. Kondisi ponton kosong dengan excavator diatasnya, dan excavator bekerja pada
maksimum depth cut.
Masing-masing dihitung dengan kondisi siap compartement / tangki yang ada pada
ponton dalam kondisi kosong tanpa muatan atau beban didalamnya.
