Dredging and construction, Pluto LNG project

The Pluto LNG project is located about 190 km northwest of the coastal town Karratha, in the Northern Carnarvon Basin, Western Australia. The project is a joint venture between Woodside Burrup Pty. Ltd., the operator, with a 90% interest, and Tokyo Gas (5%) and Kansai Electric (5%). The A$12 bn project will process gas from the Pluto and neighboring Xena gasfields.

The project was executed in two phases: first the berth pocket, part of the turning basin and two trenches were excavated to allow the construction of the new LNG jetty; then part of the turning basin and two trenches, which traverse the existing NWSV LNG shipping channel, were dredged. Dredging the two trenches early in the program was required since shipping in the NWSV LNG channel was scheduled to increase in the near future, decreasing the time available for dredging. Work took place from late November 2007 through early May 2008 with the removal of 2,100,000 m3. In the second phase, from 1 September, 2009 through July 2010, the remainder of the turning basin and the shipping channel were dredged and 5,600,000 m3 were removed.

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.

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.
