PERHITUNGAN RENCANA GARIS

(LINES PLAN)

A. Perhitungan Dimensi Kapal1.Panjang Garis Air Muat (Lwl)

Lwl= Lpp + 2 % x Lpp

(Ref : ITS Th.1982 Diktat Rencana Garis)= 102,80 + 2 % x 102,80= 104,856 m 2.Panjang Displacement (L Displ)

L Displ= 0,5 x (Lwl+ Lpp )(Ref : ITS Th.1982 Diktat Rencana Garis)

= 0,5 x (104,856 + 102,80)

= 103.828 m

3.Coefisien Midship (Cm) Formula Arkent Bont Shocker.

Cm=0,91+ (0,1x Cb )

=0,91+ (0,1x0,74 )

=0,986Memenuhi Syarat(0,95 ~ 0,99)

4.Coefisien Prismatik (Cp) Formula Troast

Cp=Cb/ Cm

=0,74/0,986

=0,750Memenuhi Syarat(0,68 0,82)
