Kapal Isap Produksi (KIP) Timah I is a Cutter Suction Dredger (CSD) type in function to extract tin ore from a mining location such as sea floor, execute initial tin preparation, and then to transport it to another place for advance process. The needs to build suction dredger based on reverse engineering method has placed the reference design analysis in a crucial step to adjust the ship design to its utilization. <br /> <br /> <br /> Two aspects of ship design analysis are ship stability and structure strength. Ship initial stability depends on the position of its center of gravity and buoyancy. A ship is possessed of stable equilibrium criteria when at a certain angle its weight and buoyancy force can produce the righting moment that able to turn ship position back into the normal position. Besides that, a ship must obey the safety policy of dredger that presupposes 50 cm minimum freeboard. In the other hand, strength analysis is focused to analyze structure strength of ladder as a support structure of suction. <br /> <br /> <br /> The analysis result shows that KIP’s design is appropriate to stable equilibrium criteria; however its freeboard doesn’t meet a demand of dredger safety policy until pontoon addition is executed. The addition a number of pontoons along with its position arrangement, finally, will yield the satisfying freeboard result. <br /> <br /> <br /> The utilizing of modeling analysis software, which based on finite element method, produces stress output of ladder structure with 1.5 of minimum safety factor. A demand to produce 2 of minimum safety factor makes ladder modification compulsory at the next step. Thus, structure addition and reposition are able to create eligible ladder design alternatives.
