Abstract

Fires can occur anywhere and anytime, including shipyards. Fires in shipyards can cause companies to incur repair costs, recover company assets, and provide insurance for victims. The existing extinguishing system is still simple and does not cover the entire area. Therefore, it is necessary to plan a fire extinguishing system with NFPA and SNI standards that can cover all areas of the company. The initial planning step is to design the pipeline system, then select pumps, calculate pipe support requirements, and calculate estimated material costs. This research resulted in a total head using pipe flow expert software of 210.114 m. The percentage of errors between manual calculations and software is 3.363%. The need for pipe support for an 8-inch pipe requires a minimum of 1 support, while a 6-inch pipe requires a minimum of 71 supports. So, theestimated cost of materials and equipment in this plan is IDR 3,443,630,750.

Abstract

Shipyards have facilities that have the potential to cause fires because there is work that generatesheat and contains flammable materials. The existing hydrant system at the shipyard is still simple and does notcover the entire area. Therefore, it is necessary to plan a hydrant system that can cover all areas in accordancewith NFPA and SNI standards. Planning begins with determining the number and placement of hydrant pillars,pipe routing, head loss calculations, and pump selection. The pipeline requires 7.776 m of 8-inch pipe, and 6-inch pipe requires 1915.477 m of pipe. The total head losses obtained from the calculation at the farthesthydrant pillar is 217.426 m. The selected pump is a Wilo 150 GF with a pump head of 240 m and a capacity of1250 US GPM.
