APDL – Structural rehabilitation of the Oil tankers terminal

ABOUT

The structure which was subject to intervention dates from 1967 and consists of three berth zones: a mooring for oil tankers, a viaduct and a pipeline. These structures had never been subject to rehabilitation, with the exception of the viaduct, in 1993. The oil tanker terminal extends along more than 1750 meters, allowing the simultaneous mooring of three oil tankers, within 100, 70 and 40 meters long berths. The inspection was focused only on the emerged elements, such as reinforced concrete slabs, prestressed beams and reinforced concrete blocks.

The performed inspection revealed severe concrete pathologies mainly caused by corrosion, in some part promoted by microcracking due to accidental loads from ships and in others by carbonation of concrete, all factors that contributed to the chloride ingress.

The rehabilitation design addressed the general degradation of the structures, and measures of protection, reinforcement and replacement were then prescribed, in order to ensure safety for an extended lifetime in a very demanding environment.

GEG was responsible for the inspection plan, the extensive evaluation of structural problems and the design of the rehabilitation work of the concrete of the oil tanker’s terminal in the Port of Leixões, in the north jetty.


This project is included in GEG’s vast portfolio of projects in the Port of Leixões – one of the most important port infrastructures and maritime communication gates of Portugal – where GEG has been developing, for over two decades, a continuous and full range of activities in multiple areas.
