Port construction,
Khalifa port

The Khalifa Port and Industrial Zone (KPIZ), one of the world’s largest greenfield development projects, is part of Abu Dhabi’s major diversification plan to develop various sectors such as property, tourism, infrastructure and others. Abu Dhabi’s main existing port, Mina Zayed, is hemmed in by Abu Dhabi city, limiting its accessibility and the possibility for expansion.

The new Khalifa Port, located 4.6 km offshore, is built on an artificial island (Port Island) with a separate berth island (for Emirates Aluminum). These islands are connected to the mainland by causeways and bridges. Khalifa Port is scheduled to replace Mina Zayed by late 2012 and provides infrastructure for a wide range of industrial and commercial activities in Abu Dhabi. When completed, the first phase of Khalifa Port will handle 2 million TEUs, four times the capacity of Mina Zayed. In June 2007 the Khalifa Port Marine Consortium (KPMC) was formed with partners Boskalis Westminster Middle East Ltd., Archirodon Construction and Hyunday Engineering & Construction. In October 2007 KPMC was awarded a multi-faceted design, procurement and construction contract. The specified work included dredging of an access channel and port basin, land reclamation, rock protection works, breakwaters and quaywall construction, to be performed by the Consortium in which Boskalis had a 43% share. When the contract was awarded, most of the final Khalifa Port and Industrial Zone (KPIZ), Abu Dhabi design work for the port’s construction had yet to be done. The client – Abu Dhabi Ports Company (ADPC) – sought contractors with the skills and multidisciplinary services able to deliver design expertise as the operations progressed. Boskalis engineers from the inhouse company Hydronamic coordinated the design activities, not only in the dredging and reclamation works, but also in the rock protection works, breakwaters and construction of the quay walls, bridges and breakwaters.

Port development, Gothenburg

Gothenburg turns around some 34 million tons of cargo annually, including 700,000 TEU (containers), and is unique in the region. With regard to the variety and frequency of calls from intercontinental liner trade the port is outstanding in Sweden. The port can be reached from the sea via two different channels: Torshamnen Fairway and Böttö Fairway. From a navigational point of view both channels needed to be deepened and widened at a number of places. Thus there were two good reasons to enhance the fairways: securing the port’s future as the premier port for liner trade and creating safer navigation. This resulted into a major dredging contract which was awarded in June 2002 to Boskalis Westminster Dredging Company.

Remediation, Urk harbor area

Many port areas requiring dredging works have been forced to put projects on hold due to the absence of an environmentally safe solution for the disposal or processing of contaminated sediments. While this is a global problem, the availability of central, large-scale repositories in the Netherlands has transformed disposal economics at the national level. Nevertheless, the high level of debris encountered during the dredging of ports and harbors remains a major challenge to all contractors. The hydraulic transport of sediments with a high debris content is impossible.

Port construction, Pusan

The 4th largest container terminal in the world is located in the South East of the South Korean peninsula at Busan. As the old port is completely surrounded by the metro-city, expansion of the old port is restricted. To solve the chronic phenomenon of cargo congestion MOMAF (Ministry of Marine and Fisheries) decided in 1997 to construct a new port situated 20 km west of Busan with a final total handling capacity of 4.6 million TEU and total expenses of 4.2 billion USD.

Port construction and environmental monitoring, Mejillones

Boskalis International B.V. was working as a subcontractor to the Chilean civil contractor Empresa Constructora BELFI SA, which was awarded the contract to construct phase 1 of the New Mega Port Mejillones. This port has been developed in order to ship the copper of the Chilean mining corporation CODELCO.

Cleanup, Ketelmeer

Ketelmeer, a lake in the Netherlands with a length of some 10 kilometers and a width varying from two to three kilometers, separates the North Eastern and Southern Polders constructed during the late 1960s and early 1970s. It is a major example of the problem of 'historic pollution'. Lake Ketelmeer receives the waters of the Rijn and IJssel and over a period of three or more decades, tens of millions of cubic meters of highly contaminated sediments entered Ketelmeer from hundreds of upstream locations. The bottom was covered by polluted sediments to an average depth of 50 cm. A significant proportion of this material had to be removed, or capped by the cleaner sediments of recent years, if a normal aquatic environment was to be restored.

Tunnel construction Warnow, Rostock

The Warnow Tunnel is located in Rostock, Germany, at the old mouth of the river Warnow in the Baltic Sea. In the DDR period this area grew out to be the main harbor of East-Germany. After the 'turn' (die Wende) in 1989 the port more or less died. Goods came cheaper and quicker from Rotterdam, Bremen and Hamburg by rail.
