PERENCANAAN BALLAST PIPING SYSTEM PADA KAPAL PENUMPANG REFURBISH

Abstract

If the ship's skin (ship plate) is damaged or leaks, it will cause seawater to enter the room or compartment of the ship. This lasts until a new balance of the ship occurs or until the ship itself sinks due to water ingress. And also the negative stability of a ship that has negative stability does not have the ability to straighten back, which causes the ship to tilt again and can even become upside down. From this case, an adequate ballast system is needed. In the context of updating the ballast piping system lines, it starts with mapping the design, including the selection of materials suitable for the fluid in the pipe. The design must take into account compliance with class regulations, space efficiency, in order to increase system effectiveness and reduce environmental impact. This research includes calculating the requirements for ballast tanks, bilge line specifications, pump selection, and manual headloss analysis. The results show that the required ballast tank volume is 462 m3, with a main pipe diameter of 100 mm and branch pipes of 80 mm and sch 40. as well as the required pump power of 15 kW, which is calculated from the overall calculation results...
