Construction
and maintenance
of ports

Boskalis has extensive experience constructing and maintaining ports and waterways worldwide. Our activities include dredging port access channels, inner channels, turning basins and mooring berths and constructing breakwaters utilizing our versatile fleet of trailing suction hopper dredgers, cutter suction dredgers and backhoes. Where additional land is needed for port development, we reclaim harbor islands and land for yards and terminals. In addition, we construct quay walls and offer soil improvement by compacting and vertical/horizontal drainage.

Bringing your project to a safe haven

Constructing ports involves a lot more than just hydraulic engineering. We also conduct detailed technical and financial feasibility studies for each project, and can assess and monitor your project’s environmental impact and by applying our building with nature techniques even assist in overcoming environmental concerns. We can take care of ongoing maintenance, which can also be taken into account during the construction process. In this way we bring even the most complex project to a safe haven.

Project highlights

Dredging_port_construction_Gorgon.jpg

Creating Gorgon

In 2009, Boskalis was awarded a contract on the Chevron-operated Gorgon Project, one of the largest and most complex contracts to be undertaken in our history. Our scope of work included the design and construction of some of the port facilities at Barrow Island.

Duqm

Duqm port construction

This extraordinary EPC project we dredged a new harbor basin and entrance channel with a depth of 18 meters, constructed a kilometer-long quay wall, two 400 meter-long jetties and reclaimed land for a port platform including ground improvement and associated 4 km shore protection.

Co-creation in Brazil

From 2011-15, Boskalis was involved in the construction of one of Latin America’s largest port-industry complexes in Rio de Janeiro, Brazil. Boskalis dredged two huge access channels, a turning basin, an inner channel, mooring berths and constructed revetments for the breakwater and over 13 km of access roads.

Expansion coal terminal, Muuga

The Muuga Coal terminal, sited on a bay, east of the existing port of Muuga, is to handle some five million tons of Siberian coal a year for destinations worldwide. The coal is shipped to Muuga by rail. Future developments may include container berths and steel facilities. The main contractor for the development of the Muuga coal terminal was the Estonian project management group A.S. Merko Ehitus. The dredging subcontract was awarded in late May 2003 to Terramare Eesti O.Ü., the Estonian arm of the Finnish-based Boskalis group company Terramare Oy.

Construction drilling island and ice barriers, Kazakhstan

Agip Kazakhstan North Caspian Operating Company B.V. (Agip KCO), a consortium of eight leading oil companies, is active in the northern section of the Caspian Sea. The gas and oil reserves in this area were mapped out in 1998 and 1999. To allow for their exploitation, Boskalis International has created an artificial island measuring 225 x 225 meters, and underwater berms, for Agip KCO. Four years later, the time was ripe for the construction of the drilling island and ice barriers. Once they were in place, Agip KCO could start to extract and distribute the oil reserves.

Port construction, Daya Bay

In Daya Bay, P.R. China, a USD 4.3 billion petrochemicals complex was being built by CNOOC and Shell Petrochemicals Company (CSPC). Daya Bay is located in the southwest of China, Huizhou Municipality, Guangdong Province. The project called for the construction of two marine facilities, one nearby the petrochemicals complex, the other one further offshore. Early 2004, the Boskalis International B.V. and Nanjing Changjiang Waterway Engineering Bureau (NCWEB) partnership commenced dredging for the CSPC Nanhai Petrochemicals project. Key requirement of the project was to preserve the sensitive environment in Daya Bay. Hydronamic, Boskalis’ own engineering consultancy, designed the required monitoring plan and took responsibility for its implementation.

Creation artificial lagoon, Barcelona

Increasing or compensating nature is one of the challenges in modern infrastructural projects. Within the scope of the extension of the Port of Barcelona compensation was required for nature to be preserved. A natural reserve, south of the Port of Barcelona and north of the International Airport of Barcelona, had to be increased and was realized within the city limits of Prat de LLobregat by the use of the cutter suction dredger Para and its auxiliary equipment.

Port development, Coega

The Coega port project - on Algoa Bay at the mouth of Coega River - is designed to act as a catalyst for regional economic development. The new port and its adjacent Industrial Development Zone, 20 km east of Port Elizabeth, are described as South Africa's largest infrastructural development scheme for a decade.

Cleanup petroleum harbor, Amsterdam

The Amsterdam Petroleum harbor on the North Sea Canal has been used for the storage and transshipment of oil products since its construction in 1887. Over many years routine operations and unchecked discharges resulted in severe contamination of the harbor.
