Port upgrade, Pointe Noire

The rehabilitation of the Port of Pointe-Noire focused on the renovation and upgrading of the main infrastructure of the port and its adaptation to developments in containerized traffic, offering a draught of -15 m. Furthermore, the work included the construction of a protective berm, an extension of the external breakwater, the rehabilitation and extension of quays, and dredging work.

The projects executed by Boskalis are part of an investment program that consists of multiple phases. Infrastructural upgrades are ongoing within Congo. The current port upgrade phase consists of the following activities:
  • Maintenance and deepening of the channel and turning basin to allow for larger vessels;
  • Expanding the area for container storage and protecting the area with slope protection works;
  • The installation of a breakwater to deflect the littoral current away from the entrance channel and to act as a sand trap, extending the dredging interval in the channel from 2 to 5 years;
  • The installation and extension of additional quay length and the upgrade of the current container quay.

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.
