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.

QuayQuip has just won another major order for an iron ore transhipment berth, following the recent success with Moma Sands. The London Mining plc’s Marampa Iron Ore Mine will be served by a barge loading facility at Thofayem, 50km upstream of from the Sierra Leone capital Freeport, on the southern bank of the Port Loko River. The installation will be QuayQuip’s largest true ‘Flat Pack Port’ to date.
London Mining plc was founded in 2005 to supply ore to the global steel industry. Headquartered in the UK, it currently operates in Africa, the Americas, the Arabian peninsula and China. Marampa was acquired in 2006. The mine first operated between 1933 and 1975; approval was recently granted to London Mining to restart production. The facility is eventually expected to handle between five and eight million tonnes of ore per year.
In mid-October 2010, QuayQuip tendered for the manufacture and supply of the entire berth. The winning design’s main structure is a series of 22 floating, interlocking platform sections, each 12m long and 3.5m wide: a total length of 260m, 45 guide piles and a 30m gangway, all supplied by QuayQuip.

QuayQuip supplied complete systems for a recent project at an LNG supply facility, from steel and fender units to the smallest fixings.
Full traceability for several thousand parts is never trival. Every fender supplied had its own ITP (Inspection and Test Plan) among other documentation. A team of twenty QuayQuip inspectors and engineers worked at the factory to monitor the process in fine detail.

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.
