Image 1 — Towers and cables over process units (conceptual)

Overview

The concept

Tall towers carry, through stay cables, a net that spans several process units at once, in the manner of cable-stayed bridges. The wide column-free span keeps room for cranes and maintenance, with side walls around the perimeter.

Proposed purpose

To study covering the highest-priority units without obstructing operations and maintenance.

Introductory details

Applications, components and considerations

Potential applications

■  Main process units

■  Areas needing free crane movement

■  High-priority zones

Components (overview level)

■  Structural steel towers on deep foundations

■  Steel or composite stay cables

■  Modular net panels

■  Net side walls

■  Steel frames linking cables to the net

Integration & maintenance

■  Soil studies and specialist structural design

■  Openable panels above scheduled lifting points

■  Aviation warning lights on towers

■  Periodic inspection of cables and foundations

Note: Images and models are conceptual visualisations for presentation and development purposes. Any actual application is subject to engineering study, testing and the required approvals.

Discuss this concept for your project

The concept serves as a starting point for discussion; the suitable solution is defined after a site study, testing and the necessary approvals.
