ANALISIS KELAYAKAN HORIZONTAL DIRECTIONAL DRILLING (HDD) MELEWATI TAXI WAY 2 PADA PROJECT PT. WIJAYA KARYA
Abstract – Pipes or pipelines are connecting network systems for transporting produced fluids from one place to another, where the pipes are usually found in the ground or commonly called buried pipes, can also be installed above ground level or can also be called at over the land. At this time PT. Wijaya Karya is working on construction, one of which is the construction of pipelines as a means of distributing avtur fuel from the DPPU Pertamina. The project passed the Taxi with a distance of 577 meters with the method used is Horizontal Directional Drilling (HDD). The design analysis method in this final project is done by means of manual calculation by finding the Installation Load which is the attraction of the pipe which is done one by one starting from T1 (365,858 Kg), Tarc1 (3104.66 Kg), T3 (25241,465Kg), Tarc2 ( 35636,046 Kg) and T2 (73288,476 Kg), Towing Load represents the total tensile strength of pipes of 73288,476 Kg, individual load is an individual that is in accordance with the level of tensile (0,0000231 MPa), Bending (76,950 MPa) and Hoop (0,87 MPa) , the combined load is a combination of Tensile and bending (0.438), then the combined stress of Tensile, bending and Hoop (0.169), Operating Load (108.45 MPa) and the voltage gauge during operation and analysis of the tension of the pipe which is passed by the aircraft on the taxi way 2 (0,000981 MPa). All that is done by doing manual calculations and is in accordance with the permitted values that have been determined. In this research it is hoped that the Horizontal Directional Drilling (HDD) design can be used as a reference for a more optimal design. From the results of this study, variations in the angle of the pipe entering the ground (entry point) 9.01 ° and the angle of the pipe coming out of the ground (exit point) 5.71 °.
