Dredging and reclamation, Port of Peterhead

The project consisted of capital dredging, reclamation, quay construction and breakwater extension works for Peterhead Smith Embankment Development, in order to develop the area in the north of the harbour at Smith Embankment to provide sheltered berths for vessels ranging from 20 to 160 m in length.

The project was awarded to a Joint Venture between Westminster Dredging and R J McLeod, a well known Scottish Civil Engineering contractor, responsible for the piling and associated civil works involved with the new quay. Westminster Dredging carried out the dredging and reclamation following on from Rockfall, who –together with Terramare – pretreated rock within the dredge area by drilling and blasting. The majority of the dredged material was placed onshore to reclaim an area of Smith Embankment, protected by rock. To protect the new quay, a 100 m long rubble mound extension to the existing Albert Quay breakwater was constructed, for which a total of 130,000 tonnes of rock were used; the remainder armourstone with individual weights of 10 to 16 tonnes. Rock placement was carried out by Manu-Pekka fitted with a special rock grapple. Subsequently, the 120 m long, open piled quay was built along the inside of the extension to the breakwater. The orientation of the breakwater extension has been determined to minimize the reflection of waves on to the oil tanker jetty and the Princess Royal jetty on the south side of the bay. Westminster Dredging have dredged some 100,000 m3 of sand, silt, clay weathered and pretreated rock. This work was carried out by backhoe Manu-Pekka, together with split hoppers Long Sand and Cork Sand. Other associated works included the demolition of the western end of the existing Albert Quay before the new extension was constructed.

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 petroleum harbor, Amsterdam

The Amsterdam Petroleum harbor on the North Sea Canal has been used for the storage and transshipment of oil products since its construction in 1887. Over many years routine operations and unchecked discharges resulted in severe contamination of the harbor.

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).

Fixed Link between Rosario and Victoria

The Joint Venture Boskalis International - Ballast Nedam JV was a subcontractor to the Consorcio Impregilo, Hochtief, Roggio and Techint which was awarded the construction of the fixed link between Rosario, in the province of Santa Fe and Victoria, in the province of Entre Rios. The Client in this project was the Argentine Government, and the leader of the Consorcio was Impregilo. The Consorciol executed all the civil constructions such as bridges while the JV Boskalis International – Ballast Nedam (BKI/BND) constructed, using sand only, the road embankments, connecting the several bridges.
