Plug and Play Manhole Kit Holder for Storage Tank: A Comprehensive Design Analysis

摘要

A novel design of a manhole kit holder, namely "Plakhor" was developed by TBBM Boyolali of PT Pertamina (Persero). The device has an advantage of a plug and play system which has an important feature to assist the cleaning of storage tank confined space. The present report addressed the design considerations, mechanical test results, and stress analysis of the developed device. The design was developed by considering engineering standards of API 650 while the stress analysis was conducted using finite element analysis (FEA). Meanwhile, a series of mechanical tests such as tensile strength, bending, press, and torsion were also conducted to determine the mechanical strength of the material used in this design. The stress analysis results indicated that the design construction was safe enough to hold the manhole weight and in an excellent agreement to that of the physical test result.
