An evaluation of additional criteria for assessing the condition of oil terminal tanks with the aim of extending safe service life - Part 1

Abstract

This article examines topical issues regarding the monitoring technical condition for vertical cylindrical tanks of oil terminals. It presents an analysis of standards in the Russian Federation and abroad for tank technical diagnostics in the area of strength calculations when determining the remaining lifetime of tank structures. The possibility of using laser scanning technology to evaluate tank technical condition is also demonstrated. Standards in the Russian Federation, unlike abroad, recommend carrying out strength calculations of tank structures using finite element methods and 3D models. These 3D models correspond to the real geometric shapes of structures, which are mapped using discrete geodesic surveying. Surface laser scanning technologies (SLS) have been in use in both domestic and foreign practice for over 12 years. They enable the geometric parameters of structures to be checked with high accuracy during operation. The issue. SLS technologies have not previously been used in the Russian Federation to develop computer models of tank structures for strength calculations and measurements using finite element methods
