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.

The project for the land reclamation and slope protection works was awarded as a lump sum Design and Construct Contract and executed under a full Quality Assurance system. The Client was represented by a team of his own staff, which had the task to control the Contractor’s procedures as laid down in the Project Quality Plan and randomly attend the numerous testing procedures. During the preparation stage of the project Hydronamic has been involved in the review and optimisation of the design as laid down by the Client in order to advise Boskalis Westminster Middle East for taking over the design responsibility in the contract. Later on during the construction phase, Hydronamic assisted on site by the implementation of the quality system, the execution and interpretation of testing procedures, the reporting, planning and several design and engineering issues.

Dredging of sediments, Miami river

The Miami River, which flows through an urban industrial area of Miami, Florida, had not been dredged since the area was built in 1934. In 1990 the US Army Corps of Engineers advised the city that the sediment had to be removed from the river as it was impeding shipping. There was one caveat however: the sediment, contaminated with heavy metals, pesticides and oil, could not be placed in the ocean.

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.

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.

Reclamation and dewatering works, Sepetiba Bay

The German steel-maker ThyssenKrupp Steel and the Brazilian mining giant Companhia Vale do Rio Doce (CVRD) teamed up to construct a EUR 3 billion steel factory at Sepetiba. This is a small town of 36,000 inhabitants near Rio de Janeiro with good access to the Atlantic Ocean. The new steel factory allowed Brazil not only to export more of its plentiful mineral resources, but also to produce semi-finished products that can be sold at higher margins. The government authorities of Brazil and Rio de Janeiro both supported the project.

Port construction, Vuosaari

Vuosaari Harbor is the most significant harbor project in Finnish history; in fact, it is unique even on a European scale. Both existing harbors in Helsinki’s city centre are being transferred to the eastern outskirts of the city. They are being replaced with a harbor with excellent traffic connections that can meet the increasing demand for cargo handling. The Vuosaari Harbor Center will provide a competitive and modern service package, with smooth connections between harbor operations and other logistical facilities. The harbor center will comprise the gate area, the closed harbor area and the adjacent Business Parks. The fairway to the Harbor Center will be 32 km long, at least 200 m wide, and 11 m deep. The port area comprises 150 ha, of which 90 ha will be land reclaimed from the sea.
