Optimization  and detailed engineering of Breakwater, dedging and ancillary works in San Antonio Port works

According to the technical projections carried out on the basis of the current operating conditions, it has been estimated that demand for handling containers in the 5th region ports will exceed the current maximum port capacity by the middle of the next decade (2020-2030); therefore, in order to respond to these demand requirements appropriately and provide continuity and support to national foreign trade, the port's offer has to be increased significantly.

SENER is responsable of  the Optimization Engineering and the Detailed Engineering of protection works, dredging and complementary work of San Antonio works. For this purpose, the project includes the following activities:

  • Review of the available background
  • Design and optimization of the protection works in order to be verified in a physical model
  • Construction of a physical model to test the protection works of the Large-Scale Port, which will be developed by external laboratories (HR Wallinford and INH) under SENER's criteria and supervision
  • Optimization of the works according to the lab results
  • Design of a pedestrian walkway on the breakwater
  • Planning of the works, as well as the preparation of the specifications, construction methodologies, budgets and tender plans for the works

As part of its master plan, EPSA has considered the development of major transformation works and an expansion of the port's capacity and operations, with a view to fulfilling the objectives of serving the development of Chile's trading in upcoming decades.

This port will be called the Large-Scale Port and it will be located in San Antonio, Chile. The plan is to build 2 terminals that focus on the traffic of containers in their last stage. These container terminals will include a 1,730-m berthing line each, with the Large-Scale Port featuring a global capacity of 6 million TEUs per year.

When developing the Large-Scale Port, a 3,900-m breakwater that takes into account the significantly unfavorable swells will be required constructing, as well as dredging the inner dock and access points, the volume of which has been estimated to be 13 million m3. Subsequently, the area of level ground comprising the new terminals will have to be filled.

A railway access for each of the terminals has been planned in order to load/unload containers, and a semi-automated internal operating method will be implemented, just like in current modern terminals, with STS cranes, RMGs, straddle carriers and yard jockeys.
