Coastal defense and
riverbank protection

Boskalis is a leading global player in the field of coastal defense and riverbank protection. We design, construct and maintain hard sea barriers, such as dikes, dams and flood barriers, and also soft sea defenses, such as beach and near-shore replenishment. In addition, we provide innovative solutions for forms of coastal protection based on the principles of building with nature such as the sand motors and the use of mangroves.

Ensuring safety and natural balance

Safety and a natural balance are the most important aspects of good coastal protection. Our vast experience and expertise enable us to assist you with the economic and environmental assessment of your coastal protection project. We have a proven track record and the drive to maintain a well-balanced ecosystem.


Our innovative and building with nature solutions

  • Sand motors use natural forces like tides, wind, currents and waves to spread sand along the coast from a central replenishment location.
  • The creation of a wave-reducing system. Examples are the combined approach of land reclamation and new mangrove forests to protect the North Java coastal area in Indonesia and a green wave reducing dike in The Netherlands. A willow forest, planted along the front of the dike, is expected to be able to absorb up to 80% of the waves’ force.

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.

Pusan_New_Port_5_header.jpg

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.

Warnow_Tunnel__3__header.jpg

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.
