The paper presents a new quay wall design applied in the South Pars port project. The quay is constructed of 7 metre diameter circular caissons made of reinforced concrete ring elements stacked upon each other. The method was developed in order to avoid construction of a dry dock needed for casting of conventional caissons. The design conditions, design loads, and the stability calculations are explained as well as the experience from the construction of the quay.
