NEW CRUISE FERRY TERMINAL IN THE PORT OF STOCKHOLM, SWEDEN The new port facility consists of three new ferry berths and two upgraded ferry terminals. Each berth is configured with a 30 m wide movable steel ramp, submerged bulbous bow protection structures, and berth equipment.

The water depth at the berth is 11 m and the total berth length is approx. 1200 m. The suspended deck consists of double spanned prefab reinforced concrete deck elements typically 8 m x 8 m supported on prefab pile caps and approximately 1,050 tubular driven steel piles (pile length varies from 30-55 m).

All prefab elements were cast in Poland and transported to the construction site, placed on the pile caps and then cast together with the other prefab elements.

Along the inner edge of the suspended pile deck a double anchored steel sheet pile wall was installed to retain the new fill above the existing sea bed. In areas with un-sorted existing rock fill, large anchored prefab concrete L-walls were installed instead.

Cement-limestone piles and jet grouting were used in the reclamation areas to improve soil conditions. Rock armour was placed to protect the existing slopes and the new retaining walls from propeller scour. COWI is the design consultant for all structural design.

WIKINGER OFFSHORE WIND FARM, GERMANY The joint venture of COWI and IMS Ingenie- urgesellschaft mbH, led by COWI, has been entrusted with the detailed design of the foundations and the basic design of the substation.

COWI was Iberdrola’s representative in the preliminary geophysical and geotechnical investigations for the 1st German regulatory system's (BSH) release, and is finishing the detailed geotechnical investigations for the 2nd BSH release.

Before this, COWI carried out the feasibility study of the turbine foundation types, investigating concepts for monopiles, gravity based foundations and jacket foundations for depth variations up to 42 m. Based on our preliminary foundation design, we were awarded the basic design of the jacket foundations equipped with AREVA 5 MW turbine, for the application for the 2nd BSH release. The offshore wind farm is expected to deliver up to 400 MW.

For the offshore substation, COWI’s scope of work includes the mechanical and electrical design services in addition to the topside and jacket structure design.

THE PEARL-QATAR The Pearl-Qatar project involved detailed design of the reclamation works for the 400 hectare new island requiring approximately 13.5 million m³ of fill and the associated sea defence structures for the 40 km of new shoreline.

The development included private beaches along most of the perimeter, which adds to the aesthetics and exclusiveness of the development. Various concepts were developed to create a variety of beach environments that are optimised to suit the local conditions and requirements.

Numerical hydrodynamic model studies were carried out to determine the metocean design basis.

COWI has, in addition to the island design, rendered technical assistance during construction and the design of the marinas.
