Stair towers are designed to ensure safe, stable, and easy access to working areas. They feature complete landing access, handrails, and non-slip steps. In some cases, stair towers are also fitted with cladding to protect personnel from harsh environmental conditions, such as wind, snow, and far-field blasts. The stair towers are made from either steel or aluminum. Steel stair tower designs comply with Eurocode 3, while aluminum designs follow Eurocode 9. Nowatec has completed numerous projects involving the design of steel and aluminum stair towers for both onshore and offshore facilities. The design process includes strength analysis under various conditions, such as in-service use, lifting, upending, towing, and sea transportation. Additionally, joint design and strength calculations are carried out for both welded and bolted connections. |
