Design & Drawing Service


With many years of experience in the storage, handling and processing of liquids, Integ are well qualified to offer a design service to consultants, fabricators and authorities. Design calculations are carried out by our engineers using special purpose software. Detailed fabrication drawings for pressure vessels and tanks can be prepared to established design codes using CAD draughting techniques.

Pressure Vessels

Computer generated design calculations to EN13445, PD5500 and ASME VIII design codes for vertical and horizontal cylindrical vessels subject to pressure using Finglow software including modules for local loading, tall columns with wind/acceleration/seismic loading, and cyclic pressure loading.

Cylindrical Storage Tanks

Design of vertical and horizontal tanks to BS799, BS2594, EN12285, EN 14015, API 650 using in-house software including wind loading/holding down bolt design. Seismic analysis of vertical storage tanks in accordance with EN 14015 Appex G. All calculation outputs including full printout of formulae and variables etc.

Rectangular Storage Tanks

Design of internally and externally stiffened tanks to BS799 using in house software plus Roark & Young for detailed analysis of plate and section loading. Designs optimised for most economic combination of plate thickness and stiffening sections.


Simple tank and vessel support and access structures designed to BS499,BS5950 & Eurocodes using the Scale Structural Calculations Ensemble software.

Design Drawing

General arrangement and detail fabrication CAD drawings produced on AutoCAD work stations. A0 size ink jet plotter/scanner for output to film or paper. Drawings can be produced with client logo and title blocks.

Tank Surveys

For existing tanks we offer a full condition survey and report service including ultrasonic thickness checks and fitness for purpose reports including change of use when it is the intention to store higher S.G. products.


Xerox plain paper A0 size plan printer for drawing prints and reproducibles. Xerox collating photocopier for multi copying of design calculations.
