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.

Creating two berths pockets, NCIG terminal

For 200 years the Port of Newcastle has been Australia’s premier coal export harbor. Of the 95 Mtpa of various commodities such as steel, aluminum, minerals and so forth exported from Newcastle in 2008-2009, 90.5 Mtpa were attributable to coal. Average annual growth rate of coal exports from 1990 to 2006 was 6.1%. This constant increase has caused a spike in ships queuing to enter the harbour to be loaded. To increase capacity and avoid these traffic jams, a decision was made to develop a new coal stockpile area and construct a third coal terminal.

Port expansion, Balboa

The plans to expand the Panama Canal represent one of the most important infrastructure improvements of the 21st century. Since its opening in 1913 the Canal has provided the shortest and most economically viable shipping route from Pacific to Atlantic seaports. With the ever-increasing size of modern-day vessels, it was inevitable that the Canal would need to be widened and deepened. The expansion of the Canal has made the extension of the Port of Balboa at the mouth of the canal on the Pacific Ocean a necessity. The Phase 4 projects included Marine Works and Civil Works to improve two existing berths and to build a completely new berth capable of handling not only Post Panamax but also Super Post Panamax ships.

Land reclamation, North Manama Causeway

The purpose of the project was to provide additional land to accommodate a section of a proposed new highway system to service the area and to relieve congestion on the corniche road. Boskalis appointed Hydronamic (the in-house engineering department of Boskalis) to provide detailed design and on site assistance with supervision of the sub-contractor for the rock works.

Port environmental mitigation measures, Hamina

Hamina, which is close to the Russian border in south-east Finland, is a home port for the oil industry and a transit harbor for timber, cars and other goods on their way to Russia. To provide access for larger vessels it had to deepen the existing channel by two meters to 12 meters and create a new channel section. Terramare Oy, a subsidiary of Royal Boskalis Westminster, won this assignment in late 2008. The project started in July 2009.

Port development, Pipavav

As a result of the booming container market in recent years, GPPL and APM Terminals introduced a long term investment plan to further develop the port’s facilities. Phase 2 of the expansion program included the reclamation of a new storage (container stacking) area and the extension of the port’s capacity by deepening the approach, channels and berths, allowing larger (container) vessels to enter the port. Zinkcon Marine Singapore, a subsidiary of Boskalis International B.V., won the contract for the dredging and reclamation works for Phase 2. In the beginning of 2009, however, the client re-evaluated the investment against the background of the dramatic effects of the economic crisis, which seriously affected the global container market. GPPL, APMT and ZMS agreed to optimize the project in such a way that all parties would benefit.
