The last two years have been busy for QuayQuip at Cape Preston, West Australia. The Sino Iron project, CITIC Pacific’s huge new magnetite extraction and processing facility, has developed rapidly – QuayQuip are proud to have contributed fender systems and structures worth just over $2 million, across many of the berths in its new, purpose-built port.

In July an article looked at QuayQuip’s latest Pivot Fender project. As its fender systems enter service we will examine the project in more detail and share images of the installation process.

The brief

The $1.75 million order, built and installed in China, is designed to serve iron ore barges of 16,000dwt. Just under 28 million tonnes per year of processed ore will pass through the facility.

The berth posed formidable challenges: the approach height range exceeds 13m, and the structure will be subject to upward forces from wave action combined with resonance and overturning moments.

The design

QuayQuip decided to move beyond old-school design approaches. Conventional systems would have been unstable, maintenance-prone. They would also need bulky supporting structures. The design team instead combined an innovative fender panel design with hinge technology, already proved durable by the dredging industry. Designers used the latest CAD software and FEM techniques to model the lightest possible fender systems and supporting structure, all to a finer precision than would have been possible even a few years ago.

QuayQuip just took innovative fender systems a step further with a US $1.75 million Pivot Fender installation, built and installed in China.

Every year the port is scheduled to handle up to 27.6 million tonnes of processed ore using 16,000dwt barges. The berth posed several design challenges: barges may impact the berthing structure over a 13m height range, and wave action on the structure could impose significant upward forces. The design had to take resonance and overturning moments into account.
