Port development
and maintenance

Boskalis provides integrated solutions for a fully operational port - from the development of new ports to the improvement or expansion, maintenance and protection of existing ports. We cover all project phases from (pre-) feasibility and design through to construction, including dredging access channels, environmental monitoring, soil remediation and financing. We offer comprehensive infrastructure solutions (quay walls, roads, railways, tunnels and bridges) and have over a century experience in land reclamation to accommodate it. We also deliver cost-effective sea defense.

Port development – expertise managing complexity

Boskalis has a proven track record delivering complex port development projects. We use our vast experience and expertise to assess the economic and environmental impacts of your project, and manage the numerous disciplines and contractors involved in the design, planning and time-critical construction phase. We specialise in developing greenfield facilities in remote locations with limited access and infrastructure, and a heightened environmental focus.

Port protection – cost-effective, sustainable solutions

Boskalis designs, constructs and maintains breakwaters and revetments to protect your port. This may involve seabed preparation and rock installation. Our expertise in quarry management, logistics and in-situ production of concrete elements, enables us to optimize the construction process to deliver an integrated, cost-effective sea defense. Through our subsidiary Boskalis Hirdes, we can also remove unexploded ordnance.

Port infrastructure – streamlining execution

Ensuring excellent connections with the hinterland requires a wide variety of port infrastructure solutions. We streamline execution by managing subcontractors, communicating with stakeholders, eliminating interfaces and/or acting as a specialist subcontractor. We have the expertise to create new land required for development and new infrastructure.

Involve Boskalis early on and we can improve your processes, mitigate risks, minimize uncertainties and deliver the solutions you seek.

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.

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.

Rehabilitation of old breakwater, Port of Poti

The city of Poti is located at the mouth of Georgia’s largest river, the Rioni. It has been an important trade centre for centuries. Since the early 19th century, many plans have been developed for the creation of a major sea port. Construction work started in the 1850s on the main breakwater that is still protecting the port today. During its long lifetime, this structure has been maintained by frequently adding 20-60 tons of concrete cubes to the armour layer. Significant settlement of the structure over time has lowered the crest level considerably, resulting in large overtopping volumes and therefore in port-operation downtime. As a result, a rehabilitation project was executed between 2006 and 2008 by Royal Boskalis Westminster N.V. to reduce the downtime caused by overtopping waves.
