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.

Reclamation, dredging and excavation, The Wave

Through Orascom, the Omani government is developing their tourist and real estate sector in order to diversify its economical drivers. The Wave, Muscat is the first freehold tourism and residential development to be launched in the Sultanate of Oman. The USD 805 million project will stretch along 7 kilometers (4.35 miles) of beachfront land overlooking the Gulf of Oman and covers an area of approximately 2.5 million square meters (26.9 million square feet). It is located in Muscat, Oman's capital city, about 5 kilometers (3.1 miles) from Muscat’s Seeb International Airport.

Dredging, reclamation and
shore protection, Soyo LNG

Angola is one of the world’s deep water oil exploration ‘hot spots’. More than 50 significant oil discoveries in Blocks 14, 15, 17 and 18 are believed to contain at least 10 billion barrels of oil. With the increase in oil production comes large quantities of associated gas. Historically, in the absence of a local market, associated gas has been flared or reinjected into the reservoirs. Sonangol, the state oil company, and some of its oil producing partners developed the Angola LNG Project to reduce flaring of gas and curtail gas injection. Angola LNG is a joint venture project involving the major oil producers in the country. Sonangol and Chevron are the co-leaders of the project; the other partners are Total, ENI and BP.

Port expansion, Ras Laffan

The Ras Laffan project is one of the largest maritime engineering projects in the world. Its sheer size can best be viewed from space. Over a period of three years, more than 3,000 specialists have been working together to create the largest LNG harbor in the world. The total contract value is approximately USD 2 billion, with the Boskalis share amounting to 50%. Qatar has natural gas reserves of roughly 25 trillion m3, 15% of the world total. The gas is transported from the Offshore North Field (26,000 billion m3), 80 kilometers north of Qatar, into Ras Laffan, where it is liquefied and pumped into latest generation tankers.

Channel deepening, Melbourne

To maintain its position as number one container and general cargo port in Australia, the Port of Melbourne Corporation (PoMC) proposed a plan to make the port accessible to 14m draught vessels during all tidal phases. Following the selection of a partner in April 2004 an Alliance Agreement was developed between PoMC and Boskalis Australia Pty Ltd, i.e, a contract where risk sharing was the norm and Boskalis could provide advice during the project development phase using its ‘in house’ expertise and experience.

Gas fields development, Krishna Godavari basin

A large-scale dredging, trenching, pipe pulling and backfilling project. Reliance Industries develops the offshore gas field known as Block KGDWN-98/3 in the Krishna Godavari Basin, Bay of Bengal off the East Coast of India. The gas field will be linked to onshore customers and covers an area of approximately 7,500 km2. The field stretches an area 40 to 60 kilometers southeast of Kakinada. The scope of works comprised the dredging of a 21 kilometers long and 18 meters wide trench for three 24" gas pipelines, each with a 6" piggyback pipeline, one 12" effluent pipeline and two umbilical cables in water depths ranging from 0 to 50 meters. After pipe laying by the main contractor the pipeline trench was backfilled with partly rock and sand.
