11/15/2022 0 Comments Pressure vessel anchor bolt designAny large discrepancy between these two results shall be brought to the attention of the equipment design group/ Vendor. When final loading data for the equipment becomes available Civil engineer shall check the support reactions based on the principle described here. However for preliminary design Civil engineer shall calculate the load based on the principles described in this design note. Location and extent of adjacent new structures and foundations not otherwise shown in the above-referenced drawings shall be verified. Generally foundation design loads shall be based on data provided by equipment Supplier including Wind and Seismic loads. (c) Requirement of platforms and access to platforms.Ī) Level of the bottom of base plate of the equipmentĭetails to be obtained from underground drawingsī) Electrical and instrument duct banks and other u/g services.Ĭ) Locations and extent of adjacent foundations. (b) Elevation of exchanger/vessel supports. (a) Location of exchanger/vessel foundation. O) Location of cleats on vessel to connect ladders and access platform on top of the vessel. M) Piping load, passive fire proofing load etc. L) Wind and seismic loads along both direction. J) For exchangers, bundle weights if bundle is removable. I) Location of fixed and sliding ends, sliding plate thickness and Material of construction. G) Empty, erection, test and operating weights of exchanger/ vessel. The following design information is requiredĪ) Overall dimensions of exchangers/ vessels (diameter and length),ī) Centre of gravity under empty and operating conditions.Į) Size and spacing of anchor bolt holes, including slotted holes.į) Width, length and thickness of saddle support base plates. At places where I found difficult to type, I made images from the main document and pasted them below. Sorry for poor editing as Linkedin editor has limited functionality unlike MS word editor. If you bring to my notice I will correct them. However, it does not change much with regards to other codes. The below design procedure is demonstrated using BS codes and UBC 1997 ( for earthquake loading). I hope this article will help practicing civil and structural engineers. Solomon Manoharan, MIStructE who is my senior and highly experienced structural engineer. The procedure was prepared by me 10 years back and was checked and verified by Mr. In the below paragraphs a concept notes covering the design procedure for such vessels is provided. Though the vessels serve different purposes from process point of view, their foundation design procedure is more or less the same. Horizontal vessels are most common in various industrial plants.
