In 2011, QuayQuip was challenged by Transport for London to design a floating impact protection system for the new Emirates Air Line – an ambitious cable car route across the River Thames.

Working in close collaboration with the main contractors, Mace, and consultants Buro Happold and Royal Haskoning, QuayQuip had to prepare a floating barrier capable of safely dissipating large energies, and have it ready for delivery in time for the cable car entering service by summer 2012.

Toward the end of 2010 we featured a radical new floating berth design for London Mining’s iron ore facility in Marampa, Sierra Leone.

QuayQuip’s specialist engineers are now installing and commissioning the berth. In the coming weeks, barges of 20,000 tonne displacement (16,000 tonne DWT) will arrive to begin the transfer of iron ore to ships moored in deeper water.

QuayQuip has delivered another set of fender systems to the Barrow Island LNG facility in West Australia.

The centrepiece of the installation was a complete dolphin, preassembled in the factory for drop-in installation from the delivery vessel. The structure was equipped with two quad-cone (QCN1300) Parallel Motion fender systems, each rated to 3.2 megajoules.

QuayQuip helped bring the 80 year old Van Cauwelaertlock up to the latest berthing and mooring standards with the installation of both fender systems and bollards.

Two large V-fender systems made from 18 QME-1250 element fenders protect the lock corners. A further seven 2.4 metre long PFS 300 extruded fenders were installed. All systems use 100% virgin grade UHMW-PE for longer service life.

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.

Last August we published an article about the QuayQuip/Marener partnership’s upgrade of Tsawwassen Berth 4, near Vancouver in British Columbia. The berth is now hard at work receiving BC Ferries vessels on their way to and from destinations across the province.

QuayQuip has just completed another pontoon fender project. The latest installation was at Rossaveel Ferry Terminal in County Galway, Ireland. The berth will serve ferries departing for the Aran Islands, historically famous for their remote monastic communities.

Three ‘finger’ piers (floating pontoons) have been equipped with thin-walled, wide bore QCY500 cylindrical fenders in a soft rubber compound. Read more…

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.

Four years ago a trans-shipment jetty was built on the Mozambique coast to serve the Moma Sands mine, enabling the transfer of titanium ore and other heavy mineral ores to large vessels moored offshore.

The initial fender installation was not up to capacity for normal operations. QuayQuip are replacing the four existing single-cone systems with tougher double-cone systems that absorb quadruple the energy, and adding four more on the opposite side to create a double-sided berth. New Donut fenders (also known as ‘monopile fenders’) guide motorised, self-loading/unloading barges safely around the end of the jetty. Read more…

QuayQuip has recently upgraded the Holmsgarth Ferry Terminal, Lerwick, on the Isle of Noss in the Shetland Islands, following winter storm damage and the introduction of the RoRo freight vessel MV Hildasay earlier this year. Holmsgarth serves ferry routes to Aberdeen and Kirkwall, and to Hanstholom in Denmark.

The design process began with a detailed calculation of the optimal fender performance for a midship impact at any given radial angle. The rebuilt central structure incorporates the remaining capacity of the previous dolphin into a series of new piles and a concrete cap. Read more…
