Subcon Europe was contracted by Subtech Group for the design and fabrication of 1680m2 of CoastMatt™ for the scour protection of Terminal de Carvão da Matola. This dry bulk terminal has an annual export of 7.5mil tonne of coal and magnetite and the scour protection was part of the current upgrading of the terminal to accept delivery of super panamax vessels.

 

 

 

 

 

 

 

The CoastMatt™ design previously used in Subcon’s Brisbane River project was appropriated for use on this project. The use of already proven formwork and breakout tool design allowed for fast track fabrication to assist with the Client’s limited schedule. The steel work was fabricated in Cape Town and then trucked to Mozambique. Once on site, Project Engineer Jack Francis oversaw the production and installation of the CoastMatts™. Working with in conjunction with the Subtech site team and local labour services, production rates were up to 100m2/day.

 

 

 

 

 

 

 

 

 

 

In order to avoid demurrage charges of a full terminal shutdown, the CoastMatt™ was designed to be single edge lifted to allow for installation on the quayside during vessel loading times. Pig tail anchors pre-installed by divers allowed the CoastMatts™ to be secured at the base of the quay wall, then laid down of a 60° gradient to the dredged berth pocket. This method of installation allowed for the CoastMatt™ to be installed perpendicular to the quay wall while allowing divers to keep a safe distance from the load before disconnecting.

This project marks the first contract executed in the African region by Subcon. With this local exposure, several new opportunities for further work have already been presented through the project’s design engineer, PRDW. On the back of this successfully executed contract, Subcon hopes to further consolidate its presence in the region.
