Port development, Raahe

The Raahe project is the largest dredging contract in Finnish history. Access for larger ships is economically important for the clients using the port of Raahe, such as the steel company Ruukki.

So it was decided to deepen the entrance channel and to extend the port, creating more land by reclaiming the dredged material from the basin and allowing large container vessels and bulk carriers to enter the extended part of the basin. The port extension eliminates the need to transship goods at sea using barges. The project was carried out by Terramare OY (Finland), the Finnish operating company of the RBW group. The project consisted of 4 separate sections:

  • Construction of a fill area in the basin area;
  • Capital dredging of the basin area and reclaiming this material into the fill area;
  • Removal of the existing breakwater;
  • Capital dredging of the 10 km long entrance channel / fairway.

Construction drilling island and ice barriers, Kazakhstan

Agip Kazakhstan North Caspian Operating Company B.V. (Agip KCO), a consortium of eight leading oil companies, is active in the northern section of the Caspian Sea. The gas and oil reserves in this area were mapped out in 1998 and 1999. To allow for their exploitation, Boskalis International has created an artificial island measuring 225 x 225 meters, and underwater berms, for Agip KCO. Four years later, the time was ripe for the construction of the drilling island and ice barriers. Once they were in place, Agip KCO could start to extract and distribute the oil reserves.

Cleanup, Ketelmeer

Ketelmeer, a lake in the Netherlands with a length of some 10 kilometers and a width varying from two to three kilometers, separates the North Eastern and Southern Polders constructed during the late 1960s and early 1970s. It is a major example of the problem of 'historic pollution'. Lake Ketelmeer receives the waters of the Rijn and IJssel and over a period of three or more decades, tens of millions of cubic meters of highly contaminated sediments entered Ketelmeer from hundreds of upstream locations. The bottom was covered by polluted sediments to an average depth of 50 cm. A significant proportion of this material had to be removed, or capped by the cleaner sediments of recent years, if a normal aquatic environment was to be restored.

Tunnel construction Warnow, Rostock

The Warnow Tunnel is located in Rostock, Germany, at the old mouth of the river Warnow in the Baltic Sea. In the DDR period this area grew out to be the main harbor of East-Germany. After the 'turn' (die Wende) in 1989 the port more or less died. Goods came cheaper and quicker from Rotterdam, Bremen and Hamburg by rail.

Installation gas pipeline, Gelugor Mainline

The Gelugor transportation system is a 24'' gas pipeline from the Tenaga Nasional Berhad (TNB) Prai Power Station, Mainland Peninsular Malaysia across the Strait of Pinang to the TNB Gelugor Meter Station on Pinang island. The pipeline has a length of 6.4 km and was put into use in the beginning of 2000. Boskalis Offshore has constructed the protection of the pipeline with rock material. The function of the protection differs along the chainage of the pipeline. A shipping channel is situated between the island and the peninsular. The pipeline in the shipping channel has been covered for to protect against ship anchors (drop and drag).
