Construction and maintenance of ports

Project highlights

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 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.

Dredging techniques

Trailing suction hopper dredger

Trailing suction hopper dredgers can fill their own holds (hoppers) by sucking material from the seabed using a trailing suction head fitted to pipes that trail over the bed as the ship sails.

Cutter section dredger

Dredging with a cutter suction dredger takes place while the vessel is moored with spuds or anchors and consists of powerful cutting action combined with suction.

Backhoe dredger

A backhoe dredger (BHD) is a hydraulic excavator installed on a pontoon. Dredging is executed by the excavator which is mounted on a turntable at the front of the pontoon. The backhoe dredger is mainly used for dredging in shallow or confined waters.

Cleanup, Westergasfabriek

The Westergasfabriek was built by the British firm Imperial Continental Gas Association (ICGA) in 1883, and was at the time the biggest coal-fired gas factory in Amsterdam. The project site, covering four hectares, housed coal storage yards, gasometers, purification plants, a water tower and office buildings, all designed by the famous Dutch architect Isaac Gosschalk. The municipal energy company used the site for storage into the early 1990s.

Land reclamation, Shaikh Khalifa Bin Salman Causeway

The Shaikh Khalifa Bin Salman Causeway is located in the State of Bahrain in an expanse of water called the Khawr Al Qulayah. It connects the Hidd Drydock Highway to the Mina Sulman Port. This major infrastructure project is carried out in advance of the planned expansion of the Bahrain port activities. This New Port project is planned at the Hidd side and via the Shaikh Khalifa Bin Salman Causeway direct connected with the existing Mina Sulman port and Saudi Arabia. The total length of the Shaikh Khalifa Bin Salman Causeway is approximately 6,500 m, including a bridge of 400 m, which was constructed in 2000.

Tunnel construction Øresund, Denmark - Sweden

The Øresund Tunnel forms part of the Øresund Link that connects the cities of Copenhagen in Denmark and Malmö in Sweden across the Øresund.

Land reclamation Check Lap Kok airport Hong Kong

In 1996 Hong Kong was a modern city-state with almost 6 million inhabitants where air traffic was a very important component for economic activity. The old airport Kai Tak, with a single runway, was no longer able to cope with the growing number of passengers and amount of freight. The authorities decided to build a new, bigger airport at a new location in Hong Kong, a 350 hectares hilly island off the coast about 28 km west of the city center.
