Data kapal Untuk menghitung reaksi beban pada dermaga, dibutuhkan data kapal yang tertambat di dermaga tersebut. Adapun data kapal yang tambat di dermaga tersebut antara lain :

Data Kapal Utama Ukuran Nilai LOA (Length Overall) LBP (Length Before Particular) LWL (Length Water Line) B (Breath) T (Througth) H (Heigth)

Satuan 106.66 M 97.95 M 16.3000 M 16.5 M 6M 8.35 M 15.3 Knot 7.87032 M/s 3952 Ton

V (Velocity) DWT (Death Weigth Tonnage) g (Berat Jenis Air) C (Faktor Kulit Kapal Baja)

1.025 Ton/M3 1.0075

Parameter Fn (Froude Number) Cb (Coefficient Block) Cm (Coefficient Midship) Cw (Coffecient Water Line) Cph (Coefficient Prismatic Horizontal) Cpv (Coefficient Prismatic Vertical) Lcb (Longitudinal Centre of Bouyancy)

Metode Van Lammeran Ayre Van Lammeran Schneekluth

Schneekluth

Rumus Fn = V / (( G * Lbp) ^ 0.5) CB = C - 1.68 * Fn CM = 0.9 + (0.1 * Cb) Cw = (1 + 2 * Cb) / 3 Cb / Cm Cb / Cw LCB / Lbp = (8.8 -38.9 * Fn) / 100

AM (Area Midship)

Displacement (2) Koreksi Displacement Letak Lcb pada Disp Jarak midship Ldisp ke Fp Jarak midship Lbp ke fp Jarak antara midship Ldisp dengan Lbp Jarak antara Lcb terhadap midship Lbp h Volume Displacement Letak Lcb Nsp Koreksi Lcb Koreksi Volume Displacement

Vol Disp * g * c (D2 - D1) / D2 0.74 * Ldisp 0.5 * Ldisp 0.5 * Lbp Ldisp - Lbp Lcp disp - Jarak midship Ldisp dengan Lbp L disp / 20 1/3 * h * S1 (S3 + S2) / S2 LCB Disp - Lcb Nsp (Vol Disp Awal - Vol Disp NSP) / Vol Disp Awal
