ANALISA PEMASANGAN SISTEM PENGGERAK PADA KAPAL CRANE BARGE DENGAN PROPULSI ELEKTRIK

Abstract

A Crane barge ship is a ship designed specifically to have a crane on deck. The function of this
ship is to unload coal/bulk cargo at the mid-sea, which is to go the middle of the sea this sip must be towed
by Tugboat. This research will discuss the analysis of the propulsion system using electric propulsion with
azimuth thruster propeller. In this study the calculation is the resistance of the ship, power requirement by
the ship, selecting of a propeller, electrical system. The calculation resistance of the ship using maxsurf
resistance software, before simulation the model 3D of ship design in maxsurf modeler. Then if the
resistance value is determined can be used to calculate the power of electric motor requirement as the
primer mover of the ship. Then the result of these calculations can be selected as the propeller. Based on
the calculation result, the value of the ship resistance is 1555,95 kW when the ship used 4 azimuth thruster,
so the resistance value is 388,987 kN. The power of the electricity needs to supply power to motor electric
as the primer mover is 4632 kW. The Selection of propeller used is a product from thrustmaster which has
a thrust is 529 kN with a diameter propeller is 2.99 meters.
