Abstract

One of the company that provides bulk liquid and gas terminal services in Semarang is
conducting a construction project for 2 storage tank T-04 dan T-05. The two tanks in the project will
be used for HSD (High Speed Diesel) and Methanol storage. HSD and Methanol are classified as
flammable materials, so it is necessary to have installation of firefighting as the protection of fire
hazard. The problems that will be discussed in this study include planning the foam firefighting system
starting from determining the path of the piping system, calculating the minimum pump power manually
and with the help of Pipe Flow Expert Software to make comparisons. Then calculate the bladder tank
capacity requirement for foam solute storage. Researchers also modelling the mixing chamber that was
made to determine the conditions of mixing water and foam solutes. Tank T-04 and T-05 have an area
of 196.56 𝒎𝟐
. Discharge time of 50 minutes with a maximum application rate of 2.595 𝒎𝟑
/min. Tank
T-04 and T-05 each have 1 discharge outlet with a placement 1 m from the top of the roof tank. The
minimum pump power from Pipe Flow Expert software modeling is 17.14 Kw and manual calculation
is 16,638 Kw. The minimum bladder tank capacity is 2650.45 Liters. From the results of the modeling
of the mixing chamber, the author made improvements to the company's design so that the optimum
mixing was found to be 80.382%.
